If you hired Northwest Registered Agent to form your LLC, they can also get your EIN from the Internal Revenue Service (IRS).
Once the IRS approves your EIN, they’ll issue an EIN Confirmation Letter (CP 575). Northwest will provide the EIN Confirmation Letter along with your other LLC approval documents and they’ll give them to you at the same time. So it depends on what state you form your LLC in.
However, Northwest can usually get an EIN within a few business days if you have a Social Security Number (SSN) or Individual Taxpayer ID Number (ITIN). If you don’t have an SSN or ITIN, it can take a few months.
