If you are asking about the identity protection PIN (IP PIN), you can:
- Get your IP PIN online at the IRS's Get an IP PIN site, or
- Call the IRS at 1-800-908-4490 to have your IP PIN mailed to you (this can take up to 21 days)
If you got an IP PIN or CP01A notice from the IRS in the past (or you opted in to the pilot program), you must use your 2024 IP PIN to prove your identity when you file your 2024 return.
