Where to Find Your LLC EIN: CP 575 147C Letter and SS-4 Explained
Key Takeaways
- CP 575: original confirmation, issued once
- 147C: replacement verification, available by phone
- Form SS-4 copy: backup documentation
- Banks accept either CP 575 or 147C
Three Ways to Verify Your EIN
Three IRS documents contain your EIN: the CP 575 (original confirmation, issued once), the 147C (replacement verification, available anytime by phone), and your Form SS-4 copy (your original application).
Which to Use
Banks prefer the CP 575. If lost, the 147C is an accepted substitute. Your SS-4 copy is a backup. You need at least one of these documents.
