Short answer The original CP575A–J series is the notice issued when a new EIN is assigned. The IRS says it cannot duplicate or recreate that original notice. Letter 147C confirms a previously assigned EIN. Eligible Business Tax Account users can now download a digital CP575 that the IRS treats as a substitute for both.

Compare the three documents

Original CP575A–JNew EIN notice

Generated when the IRS assigns the EIN; the original series cannot be duplicated or recreated.

Digital CP575Downloadable confirmation

Available to eligible Business Tax Account users and usable as a substitute for the original notice and Letter 147C.

Letter 147CPreviously assigned EIN

Requested from the IRS when written verification of an existing EIN is needed.

Is digital CP575 equivalent to Letter 147C?

Yes. The IRS’s CP575 notice page says the digital notice is equivalent to Letter 147C and is accepted by banks and other institutions as written confirmation of the entity’s EIN.

Keep the notice permanently and make secure copies for business-verification requests. Do not publish a complete EIN confirmation or upload it to an uncontrolled document link.

How to obtain EIN confirmation

  1. Entity transcript: request an entity transcript using the IRS business transcript process.
  2. Digital CP575: eligible Business Tax Account users can download it from their account.
  3. Letter 147C: call the IRS Business and Specialty Tax line and request “Letter 147C, EIN Previously Assigned.”

The IRS lists these three options on its EIN confirmation page.

Calling for Letter 147C

The official business contact page lists 800-829-4933, Monday through Friday, 7:00 a.m. to 7:00 p.m. taxpayer local time, for EIN and business-account assistance. Verify current hours before calling. The IRS will need to authenticate an authorized caller before disclosing account information.

Have the legal name, EIN if known, responsible-party information and address of record available. A third party may need formal authorization; possessing a formation document alone does not automatically authorize disclosure.

Confirmation does not change the IRS account CP575 and Letter 147C document an EIN already on file. They do not correct a legal name, mailing address, business location, responsible party or entity classification.

If something on the record is wrong

  • Use the IRS business-name-change procedure for a legal-name change.
  • Use Form 8822-B for a business mailing/location address or responsible-party change.
  • Report a responsible-party change within 60 days, as required by the IRS.
  • Do not apply for another EIN merely to replace a lost notice.

What a bank may ask for

A bank or provider controls its own verification process. The IRS says the digital CP575 is accepted by banks and other institutions as written EIN confirmation, but an institution may still request identity, ownership or formation documents for its separate compliance review.
