About EINs
An Employer Identification Number (EIN) is also known as a Federal Tax Identification Number, and is used to identify a business entity.
This generator creates numbers that follow the correct format (2 digits, hyphen, 7 digits) but does not register them with the IRS.
What is This Tool?
An EIN generator creates realistic Employer Identification Numbers in the standard XX-XXXXXXX format used by the IRS. EINs (also called Federal Tax ID Numbers) are 9-digit numbers assigned to business entities for tax filing, banking, and federal reporting purposes.
EIN prefixes (the first two digits) are assigned by IRS campus location and range from 01-06, 10-16, 20-27, 30-48, 50-68, 71-77, 80-88, 90-95, and 98-99. This generator uses valid prefix ranges to create realistically formatted EINs for testing purposes.

Frequently Asked Questions
Are generated EINs registered with the IRS?
No. Generated EINs follow correct formatting but are not registered. Using a fake EIN for tax filing or business purposes is illegal.
What is the EIN format?
EINs are 9 digits formatted as XX-XXXXXXX, where the first two digits indicate the IRS campus that issued the number.
How is an EIN different from an SSN?
EINs identify business entities for tax purposes, while SSNs identify individuals. Both are 9 digits but use different formats (EIN: XX-XXXXXXX, SSN: XXX-XX-XXXX).
