What CP01A actually means

Not a problem — protection. The six-digit IP PIN changes every year, arrives each December/January, and must go on your return or e-filing rejects. Lose it and retrieval is online (or a mailed CP01A reissue if you can't verify).

Notice family: Identity Verification — The IRS suspects a return filed under your SSN might not be yours and won't process anything until you verify. Fast to fix when you follow the exact channel the letter names — and your refund waits until you do.
