Wrong name or address on the CP 575

Verified on November 5, 2026 against the IRS page “Employer identification number” and Form 8822-B and its instructions, cited in full at the foot of this entry.

§ 1 —First, read the defect correctly

The CP 575 prints what the IRS recorded from the SS-4: the legal name (line 1) and the mailing address (line 4). Compare it, character for character, against the formation document. Then place the defect: a name that differs from the legal name the state recorded, or an address that is wrong or has since changed. The two are not corrected the same way, and a Letter 147C corrects neither — it only reports the record as it stands (REF C-1).

§ 2 —The address: Form 8822-B

A business mailing-address or location change is reported to the IRS on Form 8822-B, Change of Address or Responsible Party — Business — the same form that reports a responsible-party change (REF B-5).² File it by mail to the address the form's instructions assign. Until the change is processed, IRS mail — including a mailed Letter 147C — goes to the old address of record, so the order of operations is: correct the address first, then request documents.

§ 3 —The name: written correction to the IRS

Where the recorded name itself is wrong — a transcription error from the application, not a later legal name change — the IRS's EIN guidance directs the entity to write to the IRS at the address where the entity files its return, explaining the correction and identifying the entity by its EIN, so the record can be amended.¹ Enclose the evidence of the correct name: a copy of the formation document as the state recorded it. Keep the letter and its mailing record with the CP 575. This library states the route as the IRS publishes it; where a reader's case is a legal name change rather than an error, the reporting follows the return-filing instructions for the entity's form, and that distinction is one to confirm against the current IRS guidance for the entity type before writing.

§ 4 —Verifying the correction landed

After the correction has had time to process, request Letter 147C (REF C-1). The 147C prints the name and address currently on file: it is the cheapest proof that the record now reads as it should, and it is the document to give a bank whose name-match failed on the old spelling.
