What Is a 147C Letter From the IRS?

A 147C letter is a formal letter issued by the U.S. Internal Revenue Service (IRS) which verifies that the Employer Identification number (EIN) issued to your business is in their records. The 147C letter is typically requested by businesses needing proof of their EIN when they do not have the original EIN Confirmation Letter (CP 575). The 147C letter serves as legal verification of the EIN of your business as shown in the records of the IRS.

Why Is a 147C Letter Important?

Businesses commonly need a 147C letter for:

• Opening or verifying business bank accounts
• Applying for business loans or credit
• Licensing and permits
• Payroll and tax reporting corrections
• Verification requests from third parties

It is frequently used by small business owners, self-employed contractors, and employers who must confirm EIN details for financial or legal purposes.

What Information Is Included in a 147C Letter?

The IRS 147C letter includes:

• Legal business name
• Business address on file with the IRS
• Employer Identification Number (EIN)

This information reflects exactly what the IRS has on record and is considered valid proof of EIN ownership.
