The six-digit IP PIN helps stop someone from filing a fraudulent federal individual tax return with your Social Security number (SSN) or Individual Taxpayer Identification Number (ITIN). A credit freeze restricts access to your credit report, making it harder to open new credit accounts in your name. If you are concerned about both tax-return fraud and broader identity theft, use both protections.
What an IRS IP PIN protects
An IRS IP PIN is a six-digit number assigned to an eligible taxpayer to help prevent misuse of an SSN or ITIN on a fraudulent federal income-tax return. The taxpayer and the IRS know the number, and the IRS generates a new number each year. It is a control on the tax-return filing process, not a general identity or credit lock.

Which returns use an IP PIN
The IRS identifies these covered forms: Form 1040, Form 1040-NR, Form 1040-PR, Form 1040-SR, Form 1040-SS and Form 1040-X. When the IRS has assigned an IP PIN, the taxpayer must use it on covered returns filed during the calendar year, including delinquent returns. The IRS FAQ also states that the requirement applies to amended returns. Keep the current year’s number available before preparing a return.
Why the number changes every year
An annual replacement limits the value of a number exposed in a previous filing season. A number from an earlier year is not a substitute for the current calendar year’s IP PIN. Treat the new number as a tax credential: do not post it, include it in ordinary email, or give it to a caller who contacts you unexpectedly.

Who can enroll and how to get an IP PIN
Anyone with an SSN or ITIN who can verify their identity may enroll in the IRS IP PIN program. The IRS describes three routes, with different identity-verification requirements.
1. Enroll through an IRS Online Account
An IRS Online Account is the fastest enrollment method identified by the IRS. After signing in, go to the Profile section and follow the IP PIN enrollment instructions. The program offers two enrollment choices:
- Continuous enrollment: you remain in the program and receive a new IP PIN each calendar year.
- One-time enrollment: participation ends automatically at the end of that calendar year.
Choose the option that matches your situation. Continuous enrollment is useful when you want an ongoing filing safeguard; one-time enrollment can fit a specific filing season without creating a continuing enrollment obligation.

If you cannot validate your identity for an IRS Online Account, the IRS describes Form 15227 as an alternative for applicants who fall under the agency’s stated adjusted-gross-income thresholds. The thresholds and eligibility conditions are IRS rules, so check the current form instructions before relying on this route. Do not assume that completing the form guarantees immediate enrollment; the IRS must complete its identity-verification process.

3. Visit a Taxpayer Assistance Center
Applicants who cannot use an online account or the Form 15227 route may be directed to an in-person Taxpayer Assistance Center. The IRS requires identity documents for an in-person request. Bring the documents the IRS currently accepts and follow the center’s appointment or access instructions. An in-person visit is the fallback for people whose identity cannot be validated through the other methods, not a replacement for bringing proof of identity.
How to use and protect an IP PIN
Enter the current IP PIN wherever the filing software or preparer requests it for a covered federal return. If the IRS has assigned you a PIN, omitting it or entering the wrong number can prevent electronic filing or delay processing while the IRS resolves the mismatch. The IP PIN is tied to the calendar year, so confirm that you are using the number for the year in which the return is filed.
If the IRS assigned your PIN after identity theft
After confirmed tax-related identity theft, the IRS may mail a CP01A notice containing the annual IP PIN. Keep that notice with your tax records, but do not carry the number in an unsecured location. The IRS provides channels for retrieving a lost number.

Use IRS channels to retrieve a lost IP PIN. Do not respond to an unsolicited request by phone, email, text message or social media. The IRS explicitly states that it will never use those channels to request your IP PIN. Someone asking for the number in an unexpected message is a fraud warning, even if the message uses IRS branding or claims that your refund is blocked.
What a credit freeze protects
A credit freeze restricts access to your credit report. Creditors generally will not approve new credit when they cannot review the report, so a freeze helps block identity thieves from opening new accounts such as a credit card or loan in your name. The freeze is administered through the relevant credit-reporting companies, using each company’s freeze procedure.
What happens when you want legitimate credit
A freeze can interrupt a legitimate application because the prospective creditor may need to review your report. Before applying, use the credit-reporting company’s process to lift the freeze temporarily or remove it, then reinstate the freeze after the creditor has finished its review. Keep the account credentials, confirmation details and any security information required to manage the freeze.
Why you do not have to wait for a breach
The Federal Trade Commission says consumers do not have to wait for their SSN or other personal information to be exposed in a breach, or for misuse to occur, before benefiting from a freeze. A freeze is therefore a preventive measure, not only a response to a known incident.

What a freeze does not stop
A credit freeze is aimed at new-credit fraud. It does not authenticate a federal tax return and does not supply the IRS with the six-digit credential used in the IP PIN program. It also does not, by itself, address every form of identity theft, such as misuse of an existing account or a fraudulent tax filing.

|---|---|---|
| Protected system | Federal tax-return filing | Consumer credit-report access and new-account opening |
| Main threat | Someone files a return using your SSN or ITIN | Someone seeks new credit in your name |

| Typical action | Enroll through an IRS Online Account or an IRS-described fallback route, then enter the annual PIN when required | Place a freeze with the relevant credit-reporting companies and lift it when a legitimate creditor needs access |
| Does it replace the other control? | No. It does not replace a credit freeze. | No. It does not replace an IP PIN. |
Do you need an IP PIN if you freeze your credit?
Usually, yes, if tax-return fraud is part of your concern. The controls operate on separate systems: the freeze limits a creditor’s access to your credit report, while the IP PIN helps the IRS identify an authorized federal return. Freezing your credit does not cause the IRS to require or recognize an IP PIN, and an IP PIN does not stop a lender from receiving a credit application in your name.
Choose an IP PIN when your priority is tax fraud
- You are worried that someone could file a federal return with your SSN or ITIN.
- The IRS has sent you a CP01A notice or otherwise assigned an IP PIN after confirmed tax-related identity theft.
- You want an additional filing control even though you have no known credit-account problem.
Choose a credit freeze when your priority is new-account fraud
- You want to make it harder for an identity thief to open a new card or loan in your name.
- Your personal information may have been exposed, even if you have not yet seen misuse.
- You are prepared to lift the freeze temporarily when applying for legitimate credit.
Use both when you want both protections
Using both is the broadest response supported by these two controls. The IP PIN covers the federal tax-return channel; the credit freeze covers access used in many new-credit applications. Neither one is a universal identity-theft shield, so handle each through its own administrator.
A practical setup sequence
The following order keeps the tax credential and credit controls separate while reducing the chance that you forget a required step.
- Define the threat you are addressing. If the suspected harm is a false tax return, start with the IRS IP PIN program. If it is a new account or loan, start with a credit freeze. If both are possible, do both.
- Attempt IRS Online Account enrollment. Sign in, open Profile, complete identity verification and select continuous or one-time enrollment.
- Use the IRS fallback route if needed. Check whether you meet the IRS’s current adjusted-gross-income conditions for Form 15227. If you do not, or if the IRS directs you elsewhere, arrange an in-person Taxpayer Assistance Center visit and bring the required identity documents.
- Record the current IP PIN securely. Store it where you can retrieve it while preparing covered federal returns. Do not disclose it to unsolicited contacts.
- Place the credit freeze. Follow the freeze procedures of each relevant credit-reporting company. Save confirmation information and the credentials needed to manage each freeze.
- Plan for legitimate applications. Before a lender or other creditor needs your report, lift the freeze temporarily through the appropriate company. Reinstate it when the application is complete.
- Recheck the calendar-year IP PIN. Because the IRS generates a new number each year, confirm the current number before filing in a new calendar year, including when filing a late or amended return covered by the IRS requirement.
Common mistakes and how to fix them
Assuming a freeze blocks a tax return
Problem: A taxpayer freezes every credit report and assumes a thief cannot submit a tax return. Fix: Enroll in the IRS IP PIN program as a separate step. A credit freeze controls credit-report access, not IRS return authentication.

- It can be a gift option
- Comes with secure packaging
- Helpful in various ways
Treating the IP PIN as a credit lock
Problem: A taxpayer obtains an IP PIN and expects lenders to reject new applications. Fix: Place a credit freeze with the relevant credit-reporting companies. The IP PIN is only for the tax-return channel.
Using last year’s number
Problem: The taxpayer enters an old six-digit number on a current-year return. Fix: Retrieve the current calendar-year PIN through IRS channels before filing.
Forgetting late or amended returns
Problem: The taxpayer includes the PIN on a timely original return but omits it on a delinquent or amended covered return. Fix: Apply the IRS requirement to the full set of covered filings, including Forms 1040-X and delinquent returns when the IRS has assigned an IP PIN.
Recommended Free Tools
Giving the number to an impostor
Problem: A caller or message claims to be from the IRS and asks for the IP PIN. Fix: End the contact and use official IRS channels to retrieve or verify the number. The IRS says it will never call, email, text or message you through social media to request your IP PIN.
Freezing credit without planning for a loan application
Problem: A legitimate lender cannot access the report, delaying an application. Fix: Keep the freeze-management credentials and lift the freeze temporarily before the creditor’s check, then restore it afterward.
Other identity-theft measures that may complement these controls
The FTC also identifies credit monitoring, identity monitoring, identity-recovery services and identity-theft insurance as optional services consumers may use. They are follow-on services, not substitutes for the government and credit-report controls above. A monitoring alert can help you notice activity, but it does not itself stop a fraudulent tax filing or prevent a creditor from reviewing a report. Compare the scope, renewal terms and recovery assistance of any paid service before enrolling.
Quick Recap
What to remember before filing or applying for credit
- An IP PIN is a six-digit, annually regenerated IRS credential for eligible taxpayers with an SSN or ITIN.
- IRS Online Account enrollment is the fastest route; Form 15227 and Taxpayer Assistance Centers are fallback routes under the IRS’s stated conditions.
- A credit freeze restricts credit-report access and helps block many new-credit applications.
- The two controls address different threats and do not substitute for one another.
- If you want protection against both fraudulent federal returns and new accounts, use both and manage each through its own administrator.
