The Letter That Isn't a Scam
Three genuine IRS letters look exactly like fraud: they arrive unannounced, announce that your return is frozen, and demand that you prove you are yourself. Ignore them and the refund never comes. Answer a fake version and you hand a stranger your identity. The difference is printed at the top of the page — and in who makes the first move.

The freeze
Here is the scene, because it plays out in thousands of kitchens every filing season. You filed in February. March comes, then April, and the refund does not. Instead, a letter arrives claiming the IRS received a return under your name and Social Security number and has frozen it until you verify your identity. Every instinct the modern world has taught you says this is a scam — and your instincts are pointing at the one letter in the envelope stack that is real. Letters 5071C, 4883C, and 5747C are the IRS's identity-verification letters, issued when something about a filed return — a new address, a new bank account, a mismatch the filters catch — makes the IRS ask whether the filer was you before it pays.
The freeze is total: the return is not processed and no refund moves until the verification happens. The deadline is 30 days from the date on the letter, and after a successful verification the IRS asks for patience on a scale that surprises people — processing can take up to nine weeks. And if the return named in the letter is one you never filed, that is not a reason to throw the letter away; it is the most important reason to answer it. Telling the IRS 'that wasn't me' is how the identity-theft case opens and how your own legitimate return eventually gets through.
Three letters, three doors
The letters are siblings, not triplets, and the number at the top chooses the door. Letter 5071C can be answered online, through the IRS Identity Verification Service — but you type idverify.irs.gov into your browser yourself, because the whole point is that no link in any message can be trusted to take you there; have the letter, last year's return, and this year's return on the table beside you. Letter 4883C closes the online door entirely: it is phone only, the number printed on the letter, with the Taxpayer Protection Program line at 800-830-5084 if the letter itself is lost. Letter 5747C is the strictest of the three — in person only, at a Taxpayer Assistance Center, by appointment (call 844-545-5640), carrying the letter, two forms of identification with one a current government photo ID, and the returns for the years named.
Notice the architecture, because it is the lesson: in every version, YOU initiate. The IRS starts the process the one way it starts everything — by U.S. mail — and then waits for you to walk through a door it controls. It never emails the invitation, never texts it, never calls first, and never, under any circumstances, asks for a fee, a gift card, or your Identity Protection PIN to 'release' a refund. (The PIN has its own annual letter, Notice CP01A — the harmless cousin, which asks for nothing and simply arms you to file.) The Notice Decoder now carries all four letters, each with its 'don't confuse this with' line, because confusing 4883C with 5071C wastes a week on a website that cannot help you, and confusing any of them with a scam costs a season.
Why the scammers love these letters
Fraud works by imitation, and these letters hand the imitators a perfect script: official-looking urgency, a frozen refund, and a request for the most sensitive facts a person owns. The fake versions arrive by text and email, carry links to counterfeit verification pages, and harvest exactly the documents the real process asks you to have nearby — prior returns, identification, account numbers. Everything that makes the genuine letter work is present except the one thing that cannot be faked into existence: the paper letter in your mailbox that started it all.
So the rule for the whole family fits in one sentence: if it did not begin on paper, it did not begin with the IRS. And the second rule is just as short: when the paper letter does come, do not let a healthy suspicion talk you out of a real thirty days. The scammers profit from both errors — from the family that answers the fake and from the family that ignores the real one until the freeze outlasts the season. Decode the letter, use the channel printed on it, and initiate every step yourself. That is the whole defense, and it works because you are the one who starts it.
