An Employer Identification Number, issued by the Internal Revenue Service, is the most important identifying number for US businesses, especially for tax purposes. This post addresses how you can find a lost EIN.
Find the Lost EIN Yourself
The IRS Lost or Misplaced Your EIN? page starts by recommending searches for existing records that should include the lost EIN:
- The IRS confirmation notice that was provided when the EIN was issued.
- Bank accounts that were opened, or governmental licenses that were issued, based on the EIN.
- Tax return that were filed.
