Is This Letter Really From the IRS, SSA, or Medicare? Free Notice Verification Tool
Figures & notice codes last verified against IRS.gov, SSA.gov & CMS guidance in July 2026.
Quick Answer
Legitimate government letters from the IRS, SSA, or Medicare will ALWAYS include a specific official notice code (e.g., CP2000, CP14, CP504), list your taxpayer rights, and instruct you to make payments online at IRS.gov or via U.S. Treasury check. They NEVER demand retail gift cards, wire transfers, or immediate call-ins to unofficial phone numbers.
Authenticity Checker
Sophisticated mail fraud campaigns send realistic-looking official notices demanding immediate tax payments, threatening property levies, or claiming your Social Security number has been "suspended." These fake letters feature official seals and legal warnings to create panic. This free checker helps you analyze key indicators on your letter in under two minutes to verify if it is authentic.

How to Verify a Government Notice — Step-by-Step
- Step 1 — Check the upper right corner for notice numbers. Genuine IRS letters feature a notice code (such as CP14, CP2000, or LT11) or letter number (LTR 1058) in the top right margin. Search notice definitions directly in our IRS CP14 Notice Decoder or IRS LT11 Notice Decoder.
- Step 2 — Inspect the return address and payment recipient. Official checks are payable ONLY to the "United States Treasury." If a letter demands payment to a private collection agency, individual, or gift card portal, it is fraudulent.
- Step 3 — Verify the telephone number independently. Never call the 800-number printed inside a suspicious letter. Instead, compare it with official directory numbers (IRS: 1-800-829-1040, SSA: 1-800-772-1213, Medicare: 1-800-633-4227).
- Step 4 — Review the authenticity rating. Use our tool to score your notice and get direct login links to official .gov portals where you can confirm your actual balance without calling unknown representatives.
💡 Pro Tip
Create an official online account at IRS.gov/account and ssa.gov/myaccount. If a letter claims you owe taxes or that your Social Security record has an issue, logging into your official portal will instantly display your true account balance and active digital notices, bypassing fake mail scams entirely.

Common Notice Mistakes — And How to Avoid Them
Calling the Phone Number Printed on the Suspicious Notice
Fake government letters print 1-800 call center numbers operated directly by fraudsters. Calling the printed number connects you to scam operators who pretend to be IRS agents.
The fix is to look up official agency phone numbers independently at official government portals (e.g. IRS.gov, SSA.gov, Medicare.gov).
Assuming Official Looking Seals Mean the Letter Is Real
Scammers easily download high-resolution graphics of eagles, scales of justice, and official agency logos to print at the top of fake letters.
The fix is to look for official notice numbers (CP14, CP2000, CP504) and verify the account online instead of trusting printed logos.

Frequently Asked Questions About Letter Authenticity
What are the signs a letter is really from the IRS and not a scam?
A genuine IRS letter will clearly state your rights, reference a specific tax year, and usually arrive after multiple previous notices. The IRS will never demand payment via gift cards, wire transfers, or cryptocurrency, and will not threaten you with immediate arrest.
Does the IRS ever call, email, or text me first?
No. The IRS generally initiates most contact through regular mail delivered by the United States Postal Service. They will never initiate contact via email, text messages, or social media to request personal or financial information.
Can Social Security suspend my Social Security number?
No. The Social Security Administration cannot and will not ever "suspend" or "revoke" your Social Security number. Any letter or caller claiming your number is suspended due to criminal activity is guaranteed to be a scam.
How do I verify a Medicare letter is legitimate?
Genuine Medicare letters usually match your official Explanation of Benefits (EOB). To verify, log into your secure Medicare.gov account or call 1-800-MEDICARE directly. Never call the phone number printed on a suspicious letter to verify its authenticity.
What should I do if I think I received a fake government letter?
Do not respond to the letter and do not call any phone numbers listed on it. Verify your account status by contacting the agency directly using their official .gov website or published phone number. You can also report the scam to the Treasury Inspector General for Tax Administration (TIGTA).
Is it safe to call the phone number printed on the letter?
No. Scammers often print their own fraudulent call center numbers on fake letters. If you call the number, a professional scammer will answer pretending to be a government agent. Always look up the official agency number yourself.
What is the HHS Office of Inspector General and why do they contact people?
The HHS OIG investigates fraud in health programs like Medicare. While they do conduct legitimate investigations, scammers frequently impersonate them to steal personal data. A real OIG agent will never demand money or threaten you with immediate arrest over the phone.
Can I report a fake government letter online?
Yes. You can report fake IRS letters to TIGTA or phishing@irs.gov. Scams involving Social Security can be reported to the SSA Office of the Inspector General (OIG), and Medicare fraud can be reported at Medicare.gov or by calling 1-800-MEDICARE.
