1. Federal Statutes Behind Telecommunications Fraud Charges
Telecommunications fraud does not exist as a single defined federal offense. Prosecutors charge conduct involving phone networks and electronic communications through several overlapping statutes, often filing multiple counts simultaneously. The table below shows the most frequently charged statutes and the maximum sentence each carries.
| Statute | What it covers | Max sentence |
| 18 U.S.C. § 1343 (Wire Fraud) | Schemes to defraud using wire, radio, or television communications | 20 years per count; 30 years if a financial institution is involved |
| 47 U.S.C. § 227(e) (Truth in Caller ID Act) | Caller ID spoofing with intent to defraud or cause harm | Civil: up to $10,000 per violation; criminal referral to DOJ |
| 18 U.S.C. § 1030 (CFAA) | Unauthorized access to computer or network systems | Up to 10 years per count |
| 18 U.S.C. § 1028A (Aggravated Identity Theft) | Using another person's identifying information in connection with a federal felony | Mandatory 2-year consecutive sentence |
Conspiracy charges under 18 U.S.C. § 1349 carry the same penalties as the underlying wire fraud offense and are frequently added where more than one person participated.
2. Caller Id Spoofing and Impersonation Fraud
Spoofing and impersonation charges can look straightforward on paper, but the government still has to prove specific intent, not just that false information was transmitted. Where that intent is genuinely disputed, these cases are more defensible than they first appear.
How Federal Spoofing Charges Are Built
The Truth in Caller ID Act (47 U.S.C. § 227(e)) prohibits transmitting false caller identification information with intent to defraud or cause harm. The FCC handles civil forfeitures up to $10,000 per violation and refers criminal conduct to the DOJ. Criminal prosecution relies primarily on wire fraud under 18 U.S.C. § 1343. Common impersonation targets include government agency numbers, financial institution lines, and utility providers.
In New York, spoofing-based impersonation may also support state charges under N.Y. Penal Law § 190.25 (Criminal Impersonation in the Second Degree) alongside federal counts.
What Prosecutors Must Establish
To secure a wire fraud conviction for caller ID spoofing, prosecutors must prove three things: the false caller identification was transmitted in interstate or foreign commerce; the defendant acted with specific intent to defraud, not merely to test spoofing software or prank a recipient; and the communications formed part of a scheme to obtain money or property. The intent element is where most spoofing defenses concentrate.

3. Vishing and Social Engineering Attacks
Vishing is phone based social engineering designed to extract sensitive information or induce fraudulent financial transfers. Federal prosecutors typically charge these schemes under wire fraud and, where a bank account is directly targeted, under bank fraud (18 U.S.C. § 1344) as well.
A wire fraud vishing prosecution requires proof of:
- A scheme to defraud by materially false pretenses
- Use of wire communications in interstate or foreign commerce
- The defendant's knowing and intentional participation
Conspiracy under 18 U.S.C. § 1349 can be charged even where the scheme never completed. A defendant who joined the planning phase but was arrested before placing any calls may face the same maximum sentence as someone who ran the full operation.
4. Sim Swap and Account Takeover Fraud
A SIM swap attack induces a mobile carrier to transfer a victim's phone number to a device the attacker controls, capturing two factor authentication codes that then unlock bank accounts and other financial accounts. These cases draw charges from multiple federal statutes at once, and at least one of those charges carries a mandatory prison term that courts have no discretion to reduce.
Federal Charges in Sim Swap Prosecutions
Prosecutors in SIM swap cases typically combine three theories:
- Wire fraud (18 U.S.C. § 1343) for the underlying fraudulent scheme
- CFAA (18 U.S.C. § 1030) for unauthorized access to carrier systems or financial accounts
- Aggravated identity theft (18 U.S.C. § 1028A) where the defendant knowingly uses the victim's identifying information in connection with a federal felony
In New York, parallel state charges under N.Y. Penal Law § 190.80 (Identity Theft in the First Degree) are also possible where the victim's financial loss exceeds $2,000. Courts have generally rejected the argument that remotely inducing a carrier action falls outside the CFAA's definition of unauthorized access.
The Mandatory Consecutive Sentence Problem
The § 1028A count carries a mandatory two year consecutive prison term. Courts cannot run it concurrently with the wire fraud or CFAA sentence, regardless of mitigating circumstances. That constraint dramatically narrows sentencing flexibility at the plea stage and is one of the first issues to address when evaluating a SIM swap case.

5. Fraudulent Robocalls and Tcpa Violations
The Telephone Consumer Protection Act (47 U.S.C. § 227) prohibits automated calls and prerecorded messages sent without consent. The FTC and FCC both enforce civil TCPA violations, which carry $500 to $1,500 per call. In large scale operations, cumulative civil liability can run into the tens of millions.
Where robocalls advance a fraudulent scheme, the DOJ charges wire fraud in addition to any TCPA civil referral. Each call can constitute a separate wire fraud count, and the government does not need to show that any individual call produced a completed financial transfer.
6. Toll Fraud and Pbx Exploitation
Toll fraud involves unauthorized use of telecommunications infrastructure to generate call traffic for profit, typically through premium rate number arbitrage or resale of stolen network capacity. Business PBX (private branch exchange) systems are a frequent target.
Federal prosecutors charge toll fraud primarily under wire fraud and the CFAA. The prosecution theory is that network capacity has measurable monetary value, and unauthorized use of that capacity to generate revenue satisfies the property element of the wire fraud statute. Individual defendants face a separate criminal count for each unauthorized use of the network; businesses whose systems are exploited may face regulatory exposure.
7. Defense Strategies for Telecommunications Fraud Charges
Telecommunications fraud cases rest on digital evidence: call records, carrier data, device logs, and transaction trails. A defense needs to examine both what that evidence actually shows and whether the government's legal theory holds up under scrutiny.
Challenging the Evidence
- Suppression motions: Carrier records and device data are often obtained through pen register orders or subpoenas. Where that process was legally defective, a suppression motion may remove the government's core evidence before trial.
- Authentication and chain of custody: Digital records from third party carriers must be properly authenticated before admission. Gaps in documentation give the defense grounds to challenge reliability.
Challenging the Charges and the Count Structure
- Lack of intent: Wire fraud requires specific intent to defraud. A genuine belief that the conduct was authorized, or good faith reliance on a third party, can negate this element even where harm resulted.
- Interstate nexus: Wire fraud requires use of interstate wire communications. Where all relevant calls were entirely intrastate, the federal charge may not apply.
- CFAA scope: Courts have split on how broadly to read "unauthorized access." Access that was technically permitted by the system may fall outside the statute depending on the circuit.
- Count reduction: When prosecutors stack wire fraud, CFAA, and identity theft counts, negotiating a reduction in the count structure can substantially lower total sentencing exposure, particularly where the mandatory § 1028A term is part of the stack.
