What it means
It is free and issued directly by the IRS, usually immediately through the online application. Anyone charging to obtain one is charging for a form.
Funders use it to tie the applicant to filings and tax records. On bank and SBA files it appears on the Form 4506-C authorization that pulls tax transcripts, and a mismatch between the EIN on the application and the EIN on the returns stops a file cold.
A sole proprietor with no employees can operate on a Social Security number, though an EIN is still worth having: it keeps the owner's SSN off vendor forms and is required for most business bank accounts.
Where this one catches people
An EIN creates neither business credit nor liability separation. The marketing claim that an EIN lets a business borrow "with no personal guarantee and no personal credit check" describes a small and mostly inaccessible corner of the market. Essentially every small-business funder pulls the owner's personal credit and takes a personal guaranty regardless of how the entity is registered.

Is employer identification number the same as an interest rate?
Employer Identification Number is defined above; if you are comparing it against a rate, check whether the two measures share a time dimension before you put them side by side.
Which products does employer identification number apply to?
It is not specific to one product — it appears across the market.

Can I suggest a term?
Yes — [email protected]. The glossary grows from what people are actually shown in contracts.
