An IRS Identity Protection PIN (IP PIN) and a credit freeze protect against different kinds of identity misuse. An IP PIN helps stop someone from filing a covered federal tax return using your Social Security number (SSN) or individual taxpayer identification number (ITIN). A credit freeze restricts access to your credit report to make it harder to open new credit in your name. Both are free, and you can use both if you are concerned about both tax fraud and new-account fraud.
What an IRS IP PIN and a credit freeze each protect
IRS Identity Protection PIN
An IP PIN is a six-digit number the IRS uses to verify your identity when you file covered federal individual income tax returns. It is tied to your SSN or ITIN. The IRS says eligible taxpayers can request one even if they are not required to file a return, and parents or legal guardians can request one for a dependent after identity verification.

Credit freeze
A credit freeze limits access to your credit report. Because lenders generally need to review a report before approving a new account, a freeze can help block fraudulent credit applications. It does not protect your IRS account, prevent tax-return fraud, or stop every form of identity theft. FTC: Credit freezes and fraud alerts
Compare the protections, cost, and upkeep
| Decision factor | IRS IP PIN | Credit freeze |
|---|---|---|
| Main risk addressed | Someone filing a covered federal individual return using your SSN or ITIN | Someone opening new credit in your name by accessing your credit report |
| Cost | Free | Free to place and lift |
| Who can use it | Anyone with an SSN or ITIN who can verify identity, including eligible non-filers | Consumers can freeze their files at Equifax, Experian, and TransUnion |
| How long it lasts | One calendar year; the IRS generates a new PIN each year | Until you lift it |
| What you maintain | Retrieve or receive the new PIN each year and enter the current-year PIN on covered returns filed that calendar year | Keep it in place, then temporarily lift it when a lender needs access to your report |
| Setup | An IRS online account is the fastest route; Form 15227 or an in-person appointment may be alternatives | Contact each of the three nationwide credit bureaus separately |
| Main inconvenience | A missing or incorrect PIN can lead to an e-file rejection or delay processing of a paper return | A new-credit application can be delayed until the relevant bureau freeze is lifted |

Which protection fits your situation?
Choose an IP PIN for tax-return concerns
Consider requesting an IP PIN if you have experienced tax-related identity theft, want to make it harder for someone to file a federal return using your SSN or ITIN, or want to opt in proactively. The IRS allows eligible people to request one even when they have no filing requirement. IRS identity-theft victim assistance
Freeze all three credit reports for new-account concerns
If you are worried about someone opening credit in your name, place a freeze with Equifax, Experian, and TransUnion. A freeze with one bureau does not freeze your files at the other two. This can be especially useful after a lost wallet, data breach, or other identity-theft concern.
Use both if both risks matter
An IP PIN and a credit freeze apply to separate systems, so having one does not make the other unnecessary. IRS notice guidance lists an IP PIN and a credit-file protective step separately for people whose information may have been compromised. If you have actual identity theft, report it at IdentityTheft.gov and follow any case-specific IRS instructions. IRS: Understanding your CP18A notice

A credit freeze does not lower your credit score or disable existing credit cards, but it can prevent a lender from reviewing your report for a new application until you lift it. Ask the lender which bureau it uses, lift that bureau’s freeze, and refreeze the file afterward. FTC credit-freeze guidance
How to get and use an IRS IP PIN
- Try the IRS online account. Sign in, complete identity validation if prompted, and select the IP PIN option in your profile. The IRS identifies this as the fastest enrollment route. IRS: Get an Identity Protection PIN
- Check whether Form 15227 is an option. For 2026 guidance, a taxpayer whose adjusted gross income on the last filed return was below $84,000 for an individual or $168,000 for married filing jointly may use Form 15227 if the other requirements are met. The IRS calls applicants to validate their identity. IRS IP PIN FAQs
- Request an in-person appointment if needed. If you cannot use the online or Form 15227 route, request an appointment at a Taxpayer Assistance Center and bring the required identity documents. See the IRS enrollment guidance for current instructions.
- Get the new PIN every year and use it on covered returns. An IP PIN is valid for one calendar year. Use the current-year PIN on covered federal returns filed that year, including a return for an earlier tax year filed during the calendar year. Missing or incorrect PINs can cause e-filed returns to be rejected and paper returns to be delayed for validation. IRS IP PIN FAQs
- Keep the number private. Give it to a trusted tax professional only when needed to prepare and submit your return. The IRS says it will never request your IP PIN by phone, email, text, or social media message. IRS Tax Tip 2026-56, July 16, 2026
How to place or lift a credit freeze
- Contact all three bureaus. Place a freeze separately with Equifax, Experian, and TransUnion. You can submit a request online, by phone, or by mail; there is no charge. USAGov credit-freeze guidance
- Ask a lender which bureau it will check. If you apply for new credit, lift the freeze with the bureau the lender uses rather than assuming one request covers all three.
- Allow time for processing. USAGov states that online or phone requests to place a freeze must be completed within one business day, and mailed requests within three business days. Online or phone requests to lift a freeze must be completed within one hour; mailed lift requests must be completed within three business days. These are official processing requirements, but check the bureau’s current instructions and allow time before an imminent application. USAGov credit-freeze guidance
- Refreeze the file after the lender’s review. You can keep the protection in place when the application process is finished.
When a fraud alert may be a better fit
A fraud alert is different from a freeze: it leaves your credit report accessible but asks businesses to verify your identity before opening an account. The FTC says an initial fraud alert lasts one year and can be renewed; an extended alert for identity-theft victims lasts seven years. It does not replace an IP PIN for tax-return concerns. FTC: What to know about credit freezes and fraud alerts
Neither an IP PIN nor a freeze is a blanket shield against identity theft. Official guidance describes their intended protections, but does not establish a head-to-head effectiveness rate showing that one is better overall.
