An identity protection PIN (IP PIN) is a six-digit number that prevents someone else from filing a tax return using your Social Security number (SSN) or individual taxpayer identification number (ITIN). The IP PIN is known only to you and the IRS. It helps us verify your identity when filing your electronic or paper tax return.
If you are a confirmed victim of tax-related identity theft and the IRS have resolved your tax account issues, they’ll mail you a CP01A Notice with your new IP PIN each year.
If you don't already have an IP PIN, you may get an IP PIN as a proactive step to protect yourself from tax-related identity theft. Anyone with an SSN or an ITIN can get an IP PIN including individuals living abroad.
