Introduction
Wire fraud is the workhorse of federal financial crime prosecution. Found in nearly every major fraud case, 18 U.S.C. § 1343 reaches any scheme to defraud that uses interstate wire communications—which in the modern world means almost everything.
Understanding wire fraud helps explain why so many fraud cases become federal matters, what prosecutors must prove, and what defendants face. Court documents from wire fraud prosecutions reveal a consistent framework applied across wildly different schemes.

The Statute
18 U.S.C. § 1343 Text
The statute provides:
> 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.
Breaking It Down
Key elements:
1. Scheme to defraud
2. Intent to defraud
3. Material misrepresentation (or omission)
4. Use of interstate wire communication
5. Wire use connected to the scheme
Why 20 Years?
Standard wire fraud carries 20-year maximum, but:
- If financial institution affected: Up to 30 years
- If connected to presidentially declared disaster: Up to 30 years
- Each wire is a separate count
- Multiple counts can run consecutively
What Counts as “Wire”
Modern Interpretation
Courts broadly interpret “wire communication”:
Clearly covered:
- Phone calls (including cell phones)
- Emails
- Text messages
- Wire transfers
- Internet communications
- Fax transmissions
The interstate requirement:
- Communication must cross state lines OR
- Use facilities that operate interstate
- Internet communications generally qualify
- Even local calls often route interstate
Practical Result
Nearly any modern fraud involves wire communication:
- Sending fraudulent invoice by email = wire fraud
- Phone call making false representations = wire fraud
- Text message furthering scheme = wire fraud
- Online banking transaction = wire fraud
Elements in Detail
1. Scheme to Defraud
Prosecutors must show:
What qualifies:
- Plan to deprive others of money, property, or honest services
- Doesn’t require elaborate planning
- Can develop over time
- Includes obtaining property through false pretenses
What courts look for:
- Pattern of conduct
- False representations made
- Victim reliance
- Economic harm (or potential for harm)
2. Intent to Defraud
Mental state requirement:
What prosecutors must prove:
- Defendant knowingly participated
- Defendant intended to deceive
- Defendant knew statements were false
- Purpose was to obtain something of value
How intent is shown:
- Contemporaneous statements
- Pattern of deception
- Knowledge of falsity
- Concealment efforts
3. Materiality
The misrepresentation must matter:
Materiality means:
- Capable of influencing the victim
- Victim would have acted differently with truth
- Not trivial or incidental
Examples:
- False financial statements to obtain loans = material
- Fake credentials to gain trust = material
- Misrepresenting investment returns = material
4. Wire Use
The federal “hook”:
Must be:
- Interstate (or foreign) communication
- In furtherance of the scheme
- Doesn’t have to be the fraud itself—just connected
Timing:
- Before scheme completed
- During scheme execution
- Wire use need not be the final act
How Cases Are Built
Evidence Gathering
From court documents, typical evidence includes:
Documentary:
- Emails sent and received
- Financial records showing transactions
- Wire transfer records
- Business records
Testimonial:
- Victim testimony about representations made
- Insider testimony about scheme knowledge
- Expert testimony on materiality
- Cooperator testimony
Digital:
- Phone records showing communications
- Internet activity
- Banking records
- Communication platform records
Proving Each Element
Scheme: Documents showing pattern of misrepresentation
Intent: Communications revealing knowledge of falsity
Materiality: Victim testimony and expert analysis
Wire use: Records of interstate communications
Multiple Counts
Each Wire = Potential Count
Wire fraud allows separate charges for:
- Each fraudulent email
- Each phone call furthering scheme
- Each wire transfer
- Each text message
Practical Effect
In prosecution:
- Multiple counts provide leverage
- Jury may convict on some, acquit on others
- Sentencing can be consecutive
From our coverage:
Financial crime cases routinely include dozens of wire fraud counts, each representing a separate communication in furtherance of the scheme.
Defenses and Challenges
Common Defense Arguments
No scheme to defraud:
- Legitimate business dispute
- Good faith belief in representations
- No intent to deceive
No intent:
- Mistake, not fraud
- Reasonable belief in truth
- Lack of knowledge
No materiality:
- Statements were puffery
- Victims didn’t rely
- No economic impact
What Doesn’t Work
Victim fault:
- “They should have known better” not a defense
- Victim gullibility doesn’t excuse fraud
- Duty to verify doesn’t eliminate fraud
Scheme failed:
- Attempted fraud is still fraud
- Unsuccessful scheme still criminal
- Victim recovery doesn’t negate crime
Sentencing
Guidelines Calculation
Fraud sentencing considers:
Loss amount (primary driver):
- Higher loss = higher offense level
- Intended loss can be used
- Complex calculations for ongoing schemes
Specific characteristics:
- Number of victims
- Sophistication of scheme
- Role in offense
- Vulnerable victims
- Public corruption element
Typical Sentences
From court documents:
- Small schemes (under $100K): Often probation to 2 years
- Medium schemes ($100K-$1M): Often 2-5 years
- Large schemes ($1M+): Often 5-15+ years
- Massive schemes: Can exceed 20 years with consecutive counts
