How does Middesk help verify EINs?

Overview

A Taxpayer Identification Number (TIN) is a unique identification number used by the Internal Revenue Service (IRS) in the administration of tax laws. While there are various types of TINs, all businesses will have some form of TIN, which will act as a unique identifier of a business entity.

The list of TIN types are the following:

• Social Security Number (SSN)
• Employer Identification Number (EIN)
• Individual Taxpayer Identification Number (ITIN)
• Taxpayer Identification Number for Pending U.S. Adoptions (ATIN)
• Preparer Taxpayer Identification Number (PTIN)

Today, Middesk focuses on EINs, which are assigned to business entities, as well as estates and trusts.

Verifying the EIN of a business is a crucial part of business verification. When creating a Business through Middesk with a TIN, Middesk will verify that the EIN is valid and that it matches the name passed to Middesk. If the EIN is unable to be verified or does not match the name provided, Middesk will perform a series of lookups to identify alternate names that may be associated with that EIN.
