Most taxpayers don't need an an IP PIN — the IRS only issues them in select cases.

If you know you need an IP PIN to file your taxes and you lost your CP01A letter (or never received it), you can:

• Retrieve 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). Note:  IRS live phone assistance is not available at this time. 

We're unable to issue IP PINs and you won't find them on your tax paperwork. You can only get IP PINs from the IRS.
