About EIN (United States)

What is EIN?

The EIN (Employer Identification Number) is the tax identification number for businesses in the United States, issued by the IRS. It has 9 digits in XX-XXXXXXX format and is the American equivalent of Brazil's CNPJ.

Number structure

The first two digits identify the IRS campus that processed the application. The rest is a sequential number. There is no public algorithmic check digit — EIN validation is done by querying the IRS.

Use in development

International invoicing systems, payment platforms operating in the US, and fiscal compliance applications need EIN as a business registration field. Use fictitious numbers to test these flows.
