What is a Business Number?

A Business Number typically refers to an EIN issued by the IRS for tax reporting and withholding. For sole proprietors the TIN may be an SSN. Use the number the IRS has on file for the entity.

EIN versus SSN — which to provide?

Provide the EIN when the payee is a business entity. Individuals or sole proprietors may provide an SSN. When in doubt, ask the requester which TIN they require for reporting.

What happens if the TIN is wrong?

A mismatched TIN can trigger backup withholding, reporting penalties under IRC §6721, and payment delays. Correct errors promptly and provide a corrected form to the requester.

Can the form be signed electronically?

Yes. Electronic signatures are enforceable under the ESIGN Act (15 U.S.C. §7001) and UETA where adopted, provided intent, consent, attribution, and retention requirements are met.

Who should sign the form?

An authorized representative of the entity (officer, partner, owner, or authorized agent) should sign. Document authority and retain supporting corporate resolutions if needed.

How to correct a submitted form?

Submit a corrected form to the requester with an explanation. For IRS reporting corrections, the requester may need to file corrected information returns; coordinate with the payer or tax advisor.

What the Business Number Form Is and When it's Used

The Business Number Form is a standardized document used to collect an entity's taxpayer or business identification number (for example, an Employer Identification Number (EIN) or other TIN), legal entity name, and contact details for reporting, payment, or verification purposes. It is commonly requested by payers, vendors, banks, and government agencies to support tax reporting, vendor setup, and compliance checks. The form is often integrated into onboarding, vendor management, and contracting workflows, and may be executed electronically under U.S. e-signature laws such as ESIGN and state UETA statutes.
