IRS FAQ 12.5 Small Business/Self-Employed/Other Business : Form SS-4 & Employer Identification Number (EIN)
Is an employer ID number the same as a tax ID number?
Yes, an employer identification number, or EIN, is also known as a taxpayer identification number, or TIN. A sole proprietorship that has no employees and files no excise or pension tax returns and a LLC with a single owner (where the owner will file employment tax returns) are the only businesses that do not need an employer identification number. In these instances, the sole proprietor uses his or her social security number as the taxpayer identification number.

Do businesses have to obtain the taxpayer identification number (TIN) from vendors and keep it somewhere on file?
In general, businesses are required to obtain the TIN from vendors if they are required to file any return, document or other statement that calls for the taxpayer identification numbers (TINs) of other taxpayers. Form W-9 (PDF), Request for Taxpayer Identification Number and Certification, can be used to make the request. The business should also maintain the verification of these numbers in their records.
