What Do You Do If You Forget Your Tax ID Number?

If a tax identification number is misplaced, there are a number of places or ways to find it. The Internal Revenue Service can be reached by calling the Business and Specialty Tax Line at 800-829-4933.

When calling the Business and Specialty Tax Line, the identification number will be given only to the authorized person by relaying identifying information. Examples of an authorized person include a sole proprietor, a partner in a partnership, corporate office, trustee of a trust or an estate executor.

Identification numbers can also be found by referring to any documents issued that contain the number, such as a state or local license, or contacting your bank.
