Get An Identity Protection PIN (IP PIN)

What's an IP PIN?

An IP PIN is a six-digit number assigned to eligible taxpayers that helps prevent the misuse of their Social Security number on fraudulent federal income tax returns.

Important: You currently can’t opt-out once you get an IP PIN. You must use your IP PIN to confirm your identity on all federal tax returns you file this year and in future tax years. 

Getting Your IP PIN 

To get your IP PIN, you must be eligible as determined in Step 1 below. You’ll receive your IP PIN online once we verify your identity. We’ll send you a new IP PIN each December by postal mail.

1. Determine your eligibility...

You must get an IP PIN to file your current or prior year tax returns in 2017 if:

  • You lost the CP01A Notice we sent you with your new IP PIN, or
  • You didn't receive your new IP PIN and you had one before, or
  • We rejected your e-file return because your IP PIN was missing or incorrect

You may choose to get an IP PIN only if:

2. What you need...

To get an IP PIN, you must pass our identity verification secure access process.

3. Get your IP PIN!

Note: If you previously registered for an IP PIN, Get Transcript, View Your Tax Account or an Online Payment Agreement, you should log in with the same username and password. You may be required to verify your identity again.

Unable to Get Your IP PIN Online?

If you’re unable to get your IP PIN using our Get An IP PIN tool, go to Retrieve Your IP PIN to see if you meet the requirements to have an IP PIN reissued.

Additional Information

Visit FAQs about the IP PIN for more information. Visit our Identity Protection page if you don’t meet any of the IP PIN eligibility requirements in Step 1 above and you believe you're a victim of identity theft.

Credit Security Freeze with Experian

If you've placed a credit security freeze with Experian, you must contact them to have the freeze temporarily removed to allow us to verify your identity. Once you have your IP PIN or are no longer attempting to register, you may contact Experian to resume the freeze unless you scheduled it to resume automatically.
