A Taxpayer Identification Number (TIN) is a nine-digit number issued by the Internal Revenue Service (IRS) to identify taxpayers. There are two main types of TINs:

• Employer Identification Number (EIN): An EIN is used to identify businesses and other organizations.
• Individual Taxpayer Identification Number (ITIN): An ITIN is used by individuals who do not have a Social Security number (SSN).

An EIN is not the same as a TIN. An EIN is a specific type of TIN that is used to identify businesses and other organizations. A TIN can also refer to an ITIN, which is used by individuals who do not have an SSN.

Here is a table that summarizes the key differences between an EIN and a TIN:

Here are some of the situations where you might need an EIN:

• If you are starting a business
• If you are hiring employees
• If you are opening a bank account for your business
• If you are applying for a loan for your business
• If you are registering your business with the state

If you are not sure whether you need an EIN, you can contact the IRS for more information.

To apply for an EIN, you can either file Form SS-4 online or by mail. Form SS-4 can be found on the IRS website.

Once you have an EIN, you will need to use it on all of your business tax returns and other paperwork. You will also need to provide your EIN to your bank, vendors, and other businesses that you do business with.
