The Wire Fraud Statute (18 USC 1343): Full Text Explained in Plain Language

The federal wire fraud statute, 18 U.S.C. § 1343, makes it a crime to use any wire communication in interstate or foreign commerce as part of a scheme to defraud someone of money or property.

Penalties reach up to 20 years in federal prison per count, or 30 years when a financial institution is involved.

The statute is only one paragraph long, but federal prosecutors use it to charge everything from internet scams and business email fraud to complex financial crimes and public corruption cases.

Understanding what each phrase in the statute actually means, and how federal courts have interpreted those words, is the starting point for any federal wire fraud defense.

This article walks through the full text of 18 U.S.C. § 1343, phrase by phrase, and explains in plain language what the government must prove and where the law creates openings for the defense.

What Does the Full Text of 18 USC 1343 Say?

The entire federal wire fraud statute fits into a single paragraph.

Here is the full text of 18 U.S.C. § 1343, exactly as it appears in federal law:

Whoever, having devised or intending to devise any scheme or artifice to defraud, or for obtaining money or property by means of false or fraudulent pretenses, representations, or promises, transmits or causes to be transmitted by means of wire, radio, or television communication in interstate or foreign commerce, any writings, signs, signals, pictures, or sounds for the purpose of executing such scheme or artifice, shall be fined under this title or imprisoned not more than 20 years, or both. If the violation occurs in relation to, or involving any benefit authorized, transported, transmitted, transferred, disbursed, or paid in connection with, a presidentially declared major disaster or emergency (as those terms are defined in section 102 of the Robert T. Stafford Disaster Relief and Emergency Assistance Act (42 U.S.C. 5122)), or affects a financial institution, such person shall be fined not more than $1,000,000 or imprisoned not more than 30 years, or both.

That is the whole statute.

Every federal wire fraud prosecution in the country is built on these words.

The language is broad by design.

Congress wrote it to cover a wide range of fraudulent conduct, and federal courts have interpreted it to reach virtually any dishonest scheme that touches a phone line, an email server, or an internet connection.

But broad does not mean unlimited.

The U.S. Supreme Court has repeatedly stepped in to draw boundaries around the statute’s reach, and every phrase in the text carries specific legal meaning that prosecutors must prove beyond a reasonable doubt.

The sections below break down each key phrase and explain what it means for someone facing federal wire fraud charges.

What Does “Scheme or Artifice to Defraud” Mean?

A “scheme or artifice to defraud” is any plan or course of action intended to deceive someone out of money or property through dishonest means.

Federal courts have deliberately kept this definition broad.

As the DOJ Criminal Resource Manual explains, Congress never defined “scheme or artifice to defraud” when it first used the phrase, and it has not defined it since.

Instead, courts measure fraud by what the DOJ describes as “nontechnical standards,” looking at whether the defendant engaged in “wrongdoing one in his property rights by dishonest methods or schemes” or “the deprivation of something of value by trick, chicane, or overreaching,” as the Supreme Court described in Carpenter v. United States (484 U.S. 19, 1987).

In practical terms, this means prosecutors do not need to prove that a scheme followed any particular pattern or formula.

A business email scam, a fake investment pitch, a billing fraud operation, and a public corruption scheme can all qualify as a “scheme or artifice to defraud” under the same statutory language.

The scheme does not even need to succeed.

Federal prosecutors can bring charges based on the intent to carry out the scheme, regardless of whether any victim actually lost money.

Does the Scheme Have to Be Completed for Charges to Apply?

No, and this is one of the most important things to understand about the wire fraud statute.

The text says “having devised or intending to devise,” which means federal prosecutors can charge wire fraud at two different stages.

“Having devised” covers schemes that are already in motion or fully carried out.

“Intending to devise” goes further and covers schemes that are still in the planning stage.

This forward-looking language gives prosecutors the ability to bring charges before a fraud scheme produces any results at all.

If the government can show that a person intended to create a fraudulent scheme and used a wire communication in connection with that intent, the elements of the offense can be met even if no money ever changed hands.

Where Does the Defense Challenge This Element?

The breadth of “scheme or artifice to defraud” creates both risk and opportunity.

Because the definition is so flexible, prosecutors can stretch it to cover conduct that looks more like aggressive business tactics or failed deals than actual fraud.

The primary defense against this element is good faith.

If a defendant genuinely believed that the representations being made were true, or that the business arrangement was legitimate, there is no fraudulent intent and therefore no “scheme to defraud.”

Good faith is a complete defense to wire fraud.

A defendant who acted on honest, even if mistaken, beliefs about the facts did not engage in a scheme to defraud. However, believing that a business venture will ultimately succeed does not excuse knowingly false representations made to investors or partners along the way.

Courts have also drawn a line between fraud and what is known as “puffery,” which is the kind of exaggerated sales talk that no reasonable person would take as a statement of fact.

Saying “this is the best investment opportunity you will ever see” would ordinarily be puffery, depending on context.

Saying “this investment is guaranteed to return 20% annually” when no such guarantee exists is a false representation that can support wire fraud charges.

What Does “Obtaining Money or Property by Means of False or Fraudulent Pretenses” Require?

The wire fraud statute targets schemes aimed at getting money or property through lies, and federal courts have spent decades defining what qualifies as “money or property” and what makes a pretense “false or fraudulent.”

This phrase works together with “scheme or artifice to defraud” to describe the types of dishonest conduct the statute covers.

The statutory language covers both broader deceptive schemes and specific acts of obtaining property through false pretenses, but under either theory, the scheme must target money or property.

In practice, both theories require proof that the scheme targeted money or property.

What Counts as “Money or Property” Under the Wire Fraud Statute?

“Money or property” under the wire fraud statute means traditional, recognized property interests, and the Supreme Court has repeatedly refused to stretch this phrase beyond that boundary.

The landmark case is McNally v. United States (483 U.S. 350, 1987), where the Supreme Court held that the mail and wire fraud statutes protect property rights only, not the public’s intangible right to honest government.

That decision threw out a conviction based on a theory that a public official’s failure to disclose a conflict of interest defrauded citizens of their right to honest services.

Congress responded the next year by passing 18 U.S.C. § 1346, which added honest services wire fraud back into the law as a separate category.

But the core requirement from McNally still stands for traditional wire fraud: the scheme must target actual money or property.

The Supreme Court reinforced this limit in Ciminelli v. United States (598 U.S. 306, 2023), where it unanimously rejected what was known as the “right-to-control” theory.

Under that theory, some courts had allowed wire fraud convictions when a defendant deprived someone of “potentially valuable economic information” needed to make business decisions.

The Supreme Court said no.

Justice Thomas wrote that “potentially valuable economic information necessary to make discretionary economic decisions is not a traditional property interest,” and the right-to-control theory is not a valid basis for wire fraud liability.

This matters for defense purposes because it limits what prosecutors can charge as wire fraud.

If the alleged scheme did not target actual money, tangible property, or a recognized property right, the wire fraud statute generally does not apply. The one significant exception is honest services fraud under 18 U.S.C. § 1346, which covers bribery and kickback schemes by public officials and private fiduciaries even without a traditional property loss.

What Makes a Representation “False or Fraudulent”?

The representation must be materially false, meaning it must have a natural tendency to influence, or be capable of influencing, the decision at issue.

The Supreme Court established this requirement in Neder v. United States (527 U.S. 1, 1999), holding that materiality is an element of wire fraud that the government must prove.

A statement that is technically inaccurate but lacks any natural tendency to influence the relevant decision is not material. The government does not need to prove that the victim actually relied on the false statement, which distinguishes criminal fraud from civil fraud’s reliance and damages requirements.

The false representation generally needs to be a statement of fact rather than a vague opinion, though federal courts have recognized since Durland v. United States (1896) that fraudulent promises about future conduct can also support wire fraud charges.

As noted above, general sales talk or puffery does not qualify.

Federal courts look at the totality of the defendant’s representations, the context in which they were made, and whether a reasonable person in the victim’s position would have relied on the false information in deciding to part with money or property.

Half-truths can qualify as affirmative misrepresentations on their own, because a misleading partial truth can be just as deceptive as a direct lie. Pure omissions or silence, by contrast, generally require a separate duty to disclose before they can support a wire fraud charge.

For example, a financial advisor who tells a client that an investment is “doing well” while hiding the fact that it has lost 40% of its value has made a materially false representation through omission.

What Does “Transmits or Causes to Be Transmitted by Means of Wire, Radio, or Television Communication” Cover?

This phrase is what makes wire fraud a federal crime instead of a state one, and in the internet age, it is often one of the more straightforward elements for prosecutors to establish.

The statute was written in 1952 when “wire communication” meant telephone calls, telegraph messages, and radio or television broadcasts.

Today, federal courts have interpreted this language to cover every form of electronic communication, including emails, text messages, phone calls, fax transmissions, wire transfers, internet-based transactions, social media messages, video conferences, and any data transmitted through internet infrastructure.

The DOJ Criminal Resource Manual describes the requirement as “the use of an interstate telephone call or electronic communication made in furtherance of the scheme.”

In practical terms, most fraudulent schemes that involve internet or phone communications will satisfy this element, though the government must still prove that the specific wire communication was used to execute the scheme.

What Does “Causes to Be Transmitted” Add?

The statute does not require the defendant to personally send the wire communication.

The phrase “transmits or causes to be transmitted” means that a defendant can be liable for wire communications sent by other people, so long as the defendant set the communication in motion or it was a reasonably foreseeable result of the scheme.

For example, if a person submits a fraudulent insurance claim by mail, and the insurance company processes the claim by sending an electronic payment or an internal email about it, the person who submitted the claim “caused” those wire communications to be transmitted.

Several federal circuits, including the Eighth Circuit, have held that the government must show it was “reasonably foreseeable” that interstate wire communications would be used as part of the scheme.

This standard is not hard for prosecutors to meet.

In a world where nearly every financial transaction, business communication, and government process involves electronic transmission, it is generally foreseeable that wire communications will cross state lines at some point.

What Does “In Interstate or Foreign Commerce” Require?

The wire communication must cross a state line or an international border.

This is the jurisdictional hook that makes wire fraud a federal offense rather than a state crime.

In most cases, this element is easy to establish.

Even a single email sent from Dallas to a server in another state crosses state lines.

A phone call routed through cell towers in multiple states crosses state lines.

An internet transaction processed through a bank or payment processor in a different state crosses state lines.

Federal courts have consistently held that the interstate commerce element is satisfied whenever a wire communication passes through infrastructure in more than one state, even if both the sender and the recipient are in the same state.

Because internet traffic is typically routed through servers and networks spanning multiple states, most internet-based communications will satisfy the interstate commerce requirement, though the government must establish the interstate routing through evidence in each case.

What Does “For the Purpose of Executing Such Scheme or Artifice” Mean?

The wire communication must have been used for the purpose of carrying out the fraudulent scheme, not just incidentally connected to it.

This is the nexus requirement.

Prosecutors must show that the wire communication was sent in furtherance of the fraud, meaning it played some role in advancing, continuing, or completing the scheme.

The wire itself does not need to contain any fraudulent content.

A routine email confirming a meeting, a phone call to schedule a wire transfer, or a text message coordinating logistics can all satisfy this element if the communication helped move the fraud forward.

Federal courts have interpreted “for the purpose of executing” broadly.

The communication does not need to be the central act of the fraud.

It just needs to be a step along the way.

Can Each Wire Communication Be Charged as a Separate Count?

Yes, and this is one of the most significant consequences of how the statute is structured.

Each individual wire communication made in furtherance of a fraudulent scheme can be charged as a separate count of wire fraud.

That means a single fraud scheme that involved 50 emails could result in 50 separate federal wire fraud counts, each carrying up to 20 years in prison.

In practice, the federal sentencing guidelines group related counts together, so a defendant convicted on multiple counts will not necessarily face the maximum sentence on each one served consecutively.

But the potential exposure is enormous, and prosecutors use the ability to stack counts as significant leverage during plea negotiations.

This is also why the distinction between a wire communication used “for the purpose of executing” the scheme and one that is merely incidental matters so much at trial.

Every wire the government can connect to the scheme adds another count to the indictment and another potential sentence.

What Types of Communications Qualify as “Writings, Signs, Signals, Pictures, or Sounds”?

The statute covers “any writings, signs, signals, pictures, or sounds” transmitted by wire, which is essentially everything.

This language was written to be comprehensive, and courts have treated it that way.

Emails are writings.

Phone calls are sounds.

Text messages are writings.

Images sent electronically are pictures.

Electronic data transmissions are signals.

There is no practical scenario in which a wire communication falls outside this list.

The breadth of this language is another reason the wire fraud statute has become one of the most widely used federal criminal statutes.

It is broad enough to cover every common form of electronic communication that exists today, and its open-ended language means courts are likely to extend it to new technologies as they emerge.

What Are the Penalties for Wire Fraud Under 18 USC 1343?

The base penalty for a wire fraud conviction is a fine under Title 18 (generally up to $250,000 for individuals, or $500,000 for organizations) and up to 20 years in federal prison, or both, for each count of conviction. Under 18 U.S.C. § 3571(d), the court can also impose a fine of up to twice the gross gain or twice the gross loss from the offense, which can far exceed the standard limits in large-scale fraud cases.

This 20-year maximum was established by the Sarbanes-Oxley Act of 2002.

Before that, the maximum sentence was only five years.

The increase from five to 20 years reflected Congress’s response to the wave of corporate fraud cases in the early 2000s, including Enron and WorldCom, and signaled that wire fraud would be treated as a serious federal felony.

Because each individual wire communication can be charged as a separate count, and sentences on multiple counts can run consecutively, the effective maximum sentence in a case involving multiple wires can reach well beyond 20 years.

What Is the Financial Institution Enhancement?

When a wire fraud scheme affects a financial institution, the penalties jump significantly.

The maximum prison sentence increases from 20 years to 30 years per count.

The maximum fine increases from $250,000 to $1,000,000.

The statute of limitations also extends from the standard five years to 10 years when a financial institution is affected, giving federal prosecutors significantly more time to investigate and bring charges. In 2022, Congress also enacted separate legislation extending the statute of limitations to 10 years for certain PPP loan fraud and COVID-19 EIDL fraud cases.

Federal courts have interpreted “affects a financial institution” broadly.

A scheme does not need to target a bank directly.

If a bank or other financial institution as defined in 18 U.S.C. § 20 suffers any financial exposure or risk of loss as a result of the scheme, the enhancement can apply. The § 20 definition is broader than just federally insured banks and includes mortgage-lending businesses, credit unions, insurance companies, and branches of foreign banks, among others.

For example, a mortgage fraud scheme that causes a bank to issue a loan it would not otherwise have approved “affects” that financial institution, even though the bank was not the intended target of the fraud.

What Is the Disaster Relief Enhancement?

The statute also provides enhanced penalties when the fraud occurs “in relation to, or involving any benefit authorized, transported, transmitted, transferred, disbursed, or paid in connection with, a presidentially declared major disaster or emergency.”

This provision was added by the Emergency and Disaster Assistance Fraud Penalty Enhancement Act of 2007.

The penalties under this enhancement match the financial institution enhancement: up to 30 years in prison and a fine of up to $1,000,000.

This provision has been applied in prosecutions related to fraud involving Hurricane Katrina relief funds and, more recently, in cases involving fraudulent claims for COVID-19 disaster relief benefits, including PPP loan fraud.

How Do Federal Sentencing Guidelines Apply to Wire Fraud?

The statutory maximum sets the ceiling, but the actual sentence in a wire fraud case is heavily influenced by the United States Sentencing Guidelines (USSG), specifically Section 2B1.1.

The base offense level for wire fraud under the guidelines is 7.

From there, the offense level increases based on the greater of actual or intended loss from the scheme, with enhancements ranging from +2 levels for losses over $6,500 up to +30 levels for losses exceeding $550 million under the current guidelines (amendments effective November 1, 2026 will raise these thresholds to $9,000 and $750 million, respectively).

Other enhancements can apply for schemes involving 10 or more victims, use of sophisticated means, targeting of vulnerable victims, abuse of a position of trust, or obstruction of justice.

These guideline calculations often matter more than the statutory maximum because they determine the recommended sentencing range that a federal judge will use as the starting point at sentencing.

How Has 18 USC 1343 Changed Since It Was First Enacted?

The wire fraud statute was first enacted in 1952, modeled directly on the federal mail fraud statute (18 U.S.C. § 1341), which dates back to 1872.

Congress created the wire fraud statute to extend federal fraud protections beyond the postal system to cover fraudulent schemes conducted through telephone, telegraph, radio, and television communications.

At the time, the maximum penalty was five years in prison. In 1956, Congress amended the statute to extend its reach to foreign commerce, adding coverage for wire communications crossing international borders.

Since 1952, the statute has been amended several times.

In 1989, Congress passed the Financial Institutions Reform, Recovery, and Enforcement Act (FIRREA), which added the financial institution enhancement to the wire fraud statute, increasing the maximum sentence to 20 years and adding a maximum fine of $1,000,000 for wire fraud schemes that affect a financial institution as defined in 18 U.S.C. § 20.

This change came in response to the savings and loan crisis of the 1980s, when widespread financial institution fraud exposed gaps in federal sentencing authority. The following year, in 1990, Congress increased the enhanced maximum prison sentence from 20 years to 30 years, which remains the current ceiling for wire fraud affecting a financial institution.

In 1994, Congress updated the fine language from a fixed amount to “fined under this title,” aligning it with the general federal fine provisions.

In 2002, the Sarbanes-Oxley Act quadrupled the base maximum sentence from five years to 20 years.

This was the most significant penalty increase in the statute’s history and reflected the post-Enron push to treat corporate and financial fraud as seriously as drug crimes and violent offenses.

In 2008, the Emergency and Disaster Assistance Fraud Penalty Enhancement Act added the disaster relief enhancement, extending the 30-year maximum and $1,000,000 fine to fraud schemes connected to presidentially declared disasters or emergencies.

Throughout all of these amendments, the core operative language of the statute has remained essentially unchanged since 1952.

The words “scheme or artifice to defraud” and “transmits or causes to be transmitted by means of wire, radio, or television communication” are the same words that were written more than 70 years ago.

What has changed is how broadly courts interpret those words to cover technologies that did not exist when the statute was drafted.

What Key Supreme Court Decisions Have Shaped How Courts Read the Wire Fraud Statute?

The Supreme Court has issued several landmark rulings that define the boundaries of the wire fraud statute, and each case has either expanded or narrowed what federal prosecutors can charge under 18 U.S.C. § 1343.

The table below compares the most important decisions.

The overall trend from the Supreme Court is one of tightening the statute’s boundaries.

McNally, Skilling, Kelly, and Ciminelli all pulled back prosecutorial theories that had stretched wire fraud beyond what the Court considered the statute’s text to support.

At the same time, Carpenter and Kousisis show that the Court is willing to uphold broad applications of the statute when the prosecution targets recognized property interests.

For anyone facing wire fraud charges, these cases are essential reading.

They define what prosecutors can and cannot charge, and they provide the legal framework that a defense attorney will use to challenge the government’s theory of the case.

Frequently Asked Questions

What is the federal wire fraud statute?

The federal wire fraud statute is 18 U.S.C. § 1343. It makes it a crime to use wire, radio, or television communications in interstate or foreign commerce to carry out a scheme to defraud someone of money or property through false pretenses, representations, or promises. The base penalty is up to 20 years in federal prison and a fine of generally up to $250,000 per count of conviction.

What are the elements of wire fraud under 18 USC 1343?

To convict someone of wire fraud, federal prosecutors must prove four elements beyond a reasonable doubt: the defendant knowingly devised or intended to devise a scheme to defraud, the scheme involved materially false pretenses, representations, or promises, the defendant transmitted or caused the transmission of a wire communication in interstate or foreign commerce to execute the scheme, and the defendant acted with specific intent to defraud.

What is the maximum penalty for wire fraud?

The maximum penalty for a standard wire fraud conviction is 20 years in federal prison and a fine of generally up to $250,000 per count, though the court can impose a higher fine under 18 U.S.C. § 3571(d) based on the gain or loss from the offense. When the fraud affects a financial institution or involves benefits connected to a presidentially declared disaster, the maximum increases to 30 years in prison and a $1,000,000 fine per count.

Does the wire fraud statute require proof of actual financial loss?

No. Federal prosecutors do not need to prove that any victim actually lost money. The statute requires proof of a scheme to defraud and the use of wire communications to execute it, but the scheme does not need to succeed. A person can be convicted of wire fraud even if no victim actually lost money, so long as the government proves all elements of the offense beyond a reasonable doubt.

What is the statute of limitations for wire fraud?

The standard statute of limitations for wire fraud is five years from the date of the offense. When the fraud scheme affects a financial institution, the statute of limitations extends to 10 years. This extended timeframe gives federal prosecutors significantly more time to investigate and bring charges in cases involving banks and other financial institutions covered by 18 U.S.C. § 20.

Can sending a single email lead to federal wire fraud charges?

Yes. A single email, text message, phone call, or any other wire communication sent in interstate commerce for the purpose of executing a fraudulent scheme can support a federal wire fraud charge. Each individual wire communication can be charged as a separate count, so multiple emails or calls within the same scheme can result in multiple federal charges, each carrying up to 20 years in prison.
