IRS Letter 4883C: Verify Your Identity by Phone

Act soon

← All IRS letters

What this letter means

The IRS needs you to call to verify your identity before processing your return.

Why you probably got it

An identity protection screen flagged the return.

Your deadline

Call the number in the letter. Processing is on hold until you do.

What to do next

  1. Have the letter, your return, and supporting documents ready before you call.
  2. Confirm the phone number at IRS.gov to rule out a scam.
Scam check: The IRS starts contact by mail. It will never demand payment by gift card, wire transfer, or cryptocurrency, or threaten immediate arrest. Pay only at IRS.gov or by check to the U.S. Treasury, and confirm any phone number at IRS.gov before calling.
