Employer Identification Number (EIN)

An EIN is also known as an Federal Employer Identification Number (FEIN) or Federal Tax Identification Number. It is issued by the Internal Revenue Service (IRS). A business needs an EIN to pay employees and to file business tax returns. An EIN does not expire and is unique to your business – once an EIN has been given to an entity, it will never be issued again.

Information

Most businesses must register with the US Internal Revenue Service (IRS) to obtain an Employer Identification Number (EIN). If you are not a US citizen, you may need an Individual Taxpayer Identification Number (ITIN) instead.

 

Apply for an EIN from the IRS either online, by fax, or by mail. To register online, use the IRS EIN Assistant. For fax or mail, review the IRS instructions for details. 

 

Note: A sole proprietor without employees, may use their Social Security Number instead of an EIN. This is the only exception.
