147C Letter: How to Get Your EIN Verification Letter
A 147C letter is the IRS document that verifies an EIN already assigned to a business, and it replaces the original CP-575 notice when that notice is lost. It can only be requested by phone from the IRS Business & Specialty Tax Line by an authorized person, and it is delivered by fax or mail at no cost. Banks, payment processors and payroll providers accept it as proof that a legal entity name matches its EIN.
