Government Impersonation Scams: IRS, SSA, Medicare, and Beyond

Scammers routinely pose as federal agencies. Learn how to tell a real government call from a fraudulent one—and what agencies actually do.

How Government Impersonation Scams Work

Government impersonation scams are among the most consistently reported fraud types in the United States. Callers claim to represent the IRS, Social Security Administration (SSA), Medicare, the FBI, or other official bodies—then use fabricated authority to extract money or sensitive information. The Federal Trade Commission (FTC) ranks imposter scams as a top fraud category by both volume and dollar losses reported each year.

IRS initial contact method	U.S. mail only (IRS.gov official policy)
Payment method real agencies never use	Gift cards, wire transfers, cryptocurrency (FTC and SSA OIG guidance)
Imposter scam rank among fraud types	Consistently top-reported category (FTC Consumer Sentinel Network)
Where to report SSA impersonation	oig.ssa.gov (SSA Office of the Inspector General)
Where to report all government imposters	ReportFraud.ftc.gov (Federal Trade Commission)

The mechanics are straightforward: a caller creates a false emergency, invokes a government agency's name to add credibility, and pushes the target toward a quick, irreversible payment or data disclosure. The urgency is manufactured. Real federal agencies operate through documented, verifiable processes—not surprise phone demands.

Understanding how these calls are structured can interrupt the manipulation before it succeeds. For a detailed look at the psychological levers scammers use, see The Anatomy of a Scam Call.

Agency-by-Agency: What Real Contact Looks Like

Each major federal agency has specific, documented communication practices. Knowing those practices makes it far easier to identify an impersonator.

IRS

The Internal Revenue Service initiates contact with taxpayers through U.S. mail, not phone calls or email. If there is a genuine tax issue, you will receive a written notice with a case number, a specific IRS office address, and instructions for responding or appealing. The IRS will never demand immediate payment via gift card, wire transfer, or cryptocurrency, and it will never threaten arrest for non-payment on a first contact.

Social Security Administration

The SSA does make outbound calls in some circumstances—for example, if you have an existing claim in progress—but it will never demand that you confirm your Social Security number to verify your identity, and it will not threaten suspension of your SSN. If you receive an unexpected call from someone claiming to be the SSA, hang up and call the agency directly at its publicly listed number (1-800-772-1213).

Medicare

Medicare representatives do not call beneficiaries to ask for Medicare ID numbers, bank account details, or payment. Unsolicited Medicare calls requesting personal information are almost always scams. Legitimate Medicare communications arrive by mail or through established healthcare provider channels.

Other Agencies (FBI, DEA, CBP)

Law enforcement agencies like the FBI or DEA do not call private citizens to demand payment to avoid arrest. Callers claiming you must pay a fine immediately or face federal charges are impersonating law enforcement—a federal crime in itself. Real law enforcement contact involves documented warrants, official credentials, and established legal processes.

Red Flags Common to All Government Impersonation Calls

Regardless of which agency a scammer claims to represent, several warning signs appear consistently. Phone Scam Red Flags Every Caller Should Know covers these in detail, but the most actionable signals include:

Demand for gift cards, wire transfers, or cryptocurrency — No legitimate government agency uses these payment methods.
Threats of immediate arrest or legal action — Real legal processes are documented and allow time for response.
Caller ID spoofing — Scammers routinely display authentic-looking government phone numbers. A recognizable number does not verify identity.
Instructions to keep the call secret — Legitimate agencies have no reason to request secrecy.
Requests to confirm sensitive data — Agencies that already have your information will not ask you to read it back to prove who you are.

If a call hits even one of these markers, the safest response is to hang up, then independently look up the agency's official contact information and call back through that verified channel.

Certain personal habits also increase exposure to these schemes. See Mistakes That Make You an Easier Target for Phone Scammers for practical ways to reduce your risk profile.

What to Do After a Suspicious Call

If you believe you received a government impersonation call, three steps matter most: do not pay or disclose information, document what happened, and report it. The FTC accepts reports at ReportFraud.ftc.gov; the SSA's Office of the Inspector General accepts reports at oig.ssa.gov. Both agencies use these reports to track patterns and support enforcement.

If personal information was already shared, consider checking your public records profile for inconsistencies that might signal identity fraud activity. Our overview of What Identity Theft Looks Like in a Public Records Search explains which record signals warrant follow-up.
