EIN Generator
Fictitious data, for testing only. Not tied to real people.
- Set how many numbers you need.
- Choose whether you want the formatted version with a dash after the prefix.
- Generate and copy the result.
An Employer Identification Number has nine digits written as two, then seven.
Those first two digits are the campus code — they identify which IRS processing centre issued the number. Only a specific set of values has ever been assigned, and this generator draws only from that set.
That matters because a number with an unassigned prefix is recognisable as fake by anything doing more than a length check. Generators that pick two random digits produce numbers that look wrong to anyone familiar with the format.
Historically the prefix indicated geography, but since online applications became the norm it reflects the processing campus rather than the business location.
Like the SSN, an EIN carries no verification digit. There is no arithmetic that distinguishes a valid number from an invalid one.
The only offline checks are structural: nine digits and a recognised prefix.
Real verification goes through the IRS, either via the TIN matching service available to filers or by comparing against the CP 575 assignment notice the business received.
It queries no registry. There is no business, name or tax record behind the number.
The number uses a legitimate prefix but corresponds to no registered entity.
Using an EIN that is not yours on a filing or a form is fraud. This tool exists for software development and testing.

Frequently asked questions
Because only a specific set of two-digit campus codes has ever been assigned by the IRS. Generating random digits would produce numbers recognisable as fake.
No. Like the SSN, it has none. Only structural checks are possible offline — nine digits with a recognised prefix.
An EIN identifies a business entity for tax purposes; an SSN identifies an individual. Both have nine digits, but they are formatted differently and issued by different processes.
Through the IRS — either the TIN matching service available to filers, or by checking against the CP 575 notice issued when the number was assigned.
