Letter 5071C is an identity verification request. The IRS wants confirmation that you filed the return submitted under your Social Security number.
The difference from Letter 4883C is the method. A 5071C points to an online identity verification service first, with a phone line as the backup route.
The letter includes a control number used during verification and lists the documents needed, usually the letter, the return in question, and the prior year return.
