How to Confirm Tax ID Number
- 1). Contact the IRS directly to confirm a business' or organization's ID number. The IRS has Taxpayer Assistance Centers throughout the United States, but you can speak to a representative by calling (800) 829-4933 during the week.
- 2). Request the company's recent federal or state tax filing. Many businesses file quarterly reports with the IRS and disclose their tax ID numbers.
- 3). Contact a bank or credit union if you received payment from the business through the financial institution. For example, if the business paid for services by mailing a check, call the associated bank and verify both the account and tax ID number.
- 4). Search free public databases, such as through the state comptroller. Each state maintains a system to collect taxes from individuals and entities. The Texas Comptroller of Public Accounts operates a taxable entity search, which allows consumers to confirm an entity's name and federal tax ID number.
- 5). Register through an online tax search database, such as feinsearch.com or knowx.com/fein/search.jsp. Confirm the tax ID number after disclosing the company's name and address. You also can utilize batch services to quickly check several numbers. Make sure that you understand the free trial restrictions to avoid unwanted charges.
