What is an EIN?

An EIN is an “Employer Identification Number”: A 9-digit number that is issued by the IRS and used to uniquely identify legal entities operating in the United States. Think of it as a Social Security Number (SSN) for your business.

Companies must be incorporated as an independent legal entity, like an LLC or S-Corp, to apply for an EIN. The IRS uses this number to keep track of business tax return filers.

If you're operating your company as a sole proprietor and are not yet incorporated, or need help applying for an EIN, our partner LegalZoom can help get you set up today!

EIN reimbursement will be in the form of Brex Points. Brex does not provide, nor does it guarantee, any third-party product, service, information, or recommendation.
