Hi There!

During tax season, many businesses – including corporations and LLCs – discover they need official documentation confirming their Federal Employer Identification Number (FEIN/EIN) for banking, lending, or vendor purposes.

If your original IRS CP575 notice has been misplaced, the IRS can provide an official confirmation letter.

Important: The IRS does not issue a new EIN once one has been assigned. Instead, you must request IRS Letter 147C, which serves as your official EIN confirmation.

How to Request Your EIN Confirmation

Step 1: Call the IRS Business & Specialty Tax Line

800-829-4933

Monday–Friday, 7:00 a.m.–7:00 p.m. (local time)

Step 2: Verify Your Identity

Be prepared to provide:

• Legal business name
• Responsible party’s name and SSN/ITIN
• Business address on file with the IRS
• Entity type

Step 3: Request IRS Letter 147C

Ask the IRS representative to issue Letter 147C. They can:

• Fax it to you during the call (fastest), or
• Mail it to your address of record (typically 10–14 days)

No fax machine? You may have the IRS fax the letter directly to our office at 203-933-8484, and we will promptly forward it to you.

Helpful Reminders

• The IRS will not provide your EIN verbally over the phone.
• Fax delivery is usually the quickest option.
• If your business address has changed and has not been updated with the IRS, additional steps may be required.
• Once received, please fax or email us a copy so we can maintain it in your permanent file.
• We recommend doing this for each of your corporations and LLCs.
