What is a 147C letter and how to get one from the IRS

Executive overview

Losing your EIN (Employer Identification Number) can block critical business tasks — opening bank accounts, applying for loans, filing taxes. A 147C letter is the IRS's official replacement document confirming your EIN.

You can't replace a lost CP575, but a 147C letter serves the same purpose and is easy to request.

What a 147C letter is

• Official IRS document confirming your organisation's EIN
• An EIN functions like a social security number for a business
• Not the same as a CP575 — that form is issued once only, at business formation
• Use a 147C letter when your CP575 is lost

When you need it

• Opening a business bank account or credit line
• Applying for a loan or business credit card
• Banks use the EIN to assess IRS standing and risk
• Filing taxes is easier with the number readily accessible

How to request one

• Call the IRS Business and Specialty Tax Line: 1-800-829-4933
• Available Monday–Friday, 7am–7pm
• Answer security questions to verify identity
• Choose delivery by fax (same day) or mail (4–6 weeks)
• Expect possible hold times; plan ahead if urgent

Alternatives if you can't reach the IRS

• Call your bank — they hold your EIN from account opening
• Check previously filed tax returns
• Review loan or credit card application forms
• Look at government licensing paperwork
