A Self-Select PIN is a 5-digit number you can choose that lets you electronically sign and submit your tax return. This is used as a method of authentication at the IRS. You can use the same number year after year. It is recommended that you write this number down somewhere secure so you do not forget it.

An Identity Protection Personal Identification Number (IP PIN) is a 6-digit number that is filed with your tax return to prevent someone else from fraudulently filing a tax return using your private information. This PIN shouldn’t be shared with anyone (except your tax preparer). This PIN helps the IRS verify your identity when you file. More information can be found here.
