IRS processing times vary depending on submission method and applicant eligibility. This guide outlines general processing estimates for EIN applications and how confirmations are typically issued. Processing times are determined solely by the IRS and may change without notice.
Current EIN Processing Times
| Method | Processing Time | Confirmation |
|---|---|---|
| Online (with SSN) | Typically issued immediately upon successful submission | EIN confirmation provided online |
| Fax (Form SS-4) | Estimated 4–6 weeks (subject to IRS backlog) | CP-575 confirmation letter issued by mail |
| Mail (Form SS-4) | Estimated 6–8+ weeks (varies by IRS workload) | CP-575 confirmation letter issued by mail |
For non-US residents without SSN or ITIN, online EIN application is not available. Fax submission is generally faster than mail, but timelines depend on IRS processing volume.

- Expecting faster processing than IRS estimates
