IRS Identity Verification Letters: What to Do Next

Choose the route on your IRS letter

A verification request concerns a return the IRS received. It is different from an e-file rejection that your software says was not accepted. This help center sits alongside our rejection guides, but the next step is the IRS notice response—not automatically correcting and retransmitting a return.

• CP5071, 5071C or CP5071F: follow the notice; if it offers online verification, use the Verify Your Return online guide. The IRS CP5071-family instructions cover all three names.
• CP5447, 5447C or CP5447F: the IRS CP5447-family instructions offer online verification and notice-specific alternatives. See CP5447 phone, mail and upload alternatives.
• 4883C: call the Taxpayer Protection Program number printed on the letter. Prepare with the 4883C phone-verification guide and the IRS letter instructions.
• 5747C: if you filed the return, the dedicated IRS instructions direct an in-person appointment. If you did not file, call the hotline on the letter. Use the 5747C appointment guide.

Have the documents for your verification route ready. After successful verification, use the processing and refund follow-up guide.

Does the IRS need verification before processing my return?

A separate notice about checking income or withholding has its own response process. Use the IRS refund-review guide if that is the issue described.

For a return subject to this request, the IRS needs your response before it can continue. Its 4883C instructions say it cannot process the affected return, issue a refund or credit an overpayment until it hears from you. This does not mean every taxpayer must complete the online service.

Read the response deadline on your own correspondence. If you cannot complete the requested method, follow its alternative or contact instructions. A delayed refund by itself does not establish that you need this service.

Does a verification letter mean someone stole my identity?

Not necessarily. The IRS notice instructions distinguish taxpayers who filed the return from people who did not. If you filed it, verify as directed so processing can continue. If you did not file it, tell the IRS through the notice process; someone may have used your information.

For an unfamiliar filing, see someone filed taxes in my name. For a child’s SSN issue, use the child identity-misuse guide. Do not assume every duplicate claim proves theft.

I signed into ID.me. Am I finished?

No—not just by signing in. The IRS Verify Your Return instructions say to sign in or create an account, then answer the return-verification questions. If you create an account, you may need to sign in again to finish. Follow the result and any further instructions shown by the IRS service.

What about 6330C, 6331C, 6167C or 5216?

The current IRS Taxpayer Protection Program procedures map pilot Letter 6330C to 4883C and pilot Letter 6331C to 5071C. Read the actual correspondence before choosing a route. Letter 6167C concerns incomplete authentication; Letter 5216 concerns a taxpayer who could not authenticate. Follow the specific follow-up request rather than assuming another online attempt is the solution.

Do I need Form 14039 or an IP PIN?

The IRS verification service says you do not need Form 14039 after verifying through it unless the IRS tells you otherwise. The 4883C and 5747C pages also direct recipients to their letter response instead of filing an affidavit. Use our existing conditional Form 14039 guide for separate qualifying situations.

An IP PIN protects tax filings and has its own enrollment process. Getting one should not be treated as completing a verification-letter response. See IP PIN enrollment or CP01 versus CP01A if your question concerns those notices.
