Which EIN document do you need?
Three different IRS documents cover the same nine-digit number at different points in its life. Most confusion comes from mixing them up.
| Document | What it does | When you use it |
|---|---|---|
| Form SS-4 | Applies for the EIN | Before you have a number |
| Notice CP 575 | Confirms the EIN, sent once | Arrives automatically after approval |
