IRS Identity Verification Guide: Response Methods
Understanding Identity Verification Notices
IRS identity verification notices occur when the agency cannot confirm your identity before processing a tax return, payment, or correspondence. This differs from standard audits because the IRS is not questioning your tax reporting.
The IRS issues these notices after detecting potential identity theft, suspicious filing patterns, or incomplete taxpayer information in its systems. Responding quickly and accurately to identity verification requests prevents account freezes, return processing delays, and unintended account lockouts.
Who Should Use This Guide
This guide applies to you if you received an IRS notice requesting identity verification, your tax return was rejected or flagged due to identity confirmation issues, or the IRS placed a hold on your account pending identity verification.
You should use this guide if you were asked to verify your identity online, by phone, or in person at an IRS office, or if your refund was delayed pending completion of identity verification.
This guide does not apply in the following situations
- You are responding to a formal audit examination notice
- You received a notice about unreported income or tax calculation errors
- Your issue involves a criminal investigation or fraud allegations
- You are appealing an IRS decision on substantive tax matters
- Your notice solely addresses amended return procedures or payment arrangements
Three Types of Identity Verification
The IRS uses three primary verification methods depending on the notice you receive. Letter
5071C requires online identity verification through the Identity Verification Service tool on
IRS.gov. Letter 4883C allows verification by phone or online using security questions. Letter
5747C requires scheduling an in-person appointment at an IRS Taxpayer Assistance Center, accompanied by physical documents.
Notice CP01A confirms the IRS applied identity theft protection to your account and will mail you an Identity Protection PIN. CP01A is not a request for verification documents. Identity verification notices and identity theft notices are separate processes with different procedures and requirements.
Online and Phone Verification Steps
For Letter 5071C (Online Verification)
1. Visit IRS.gov/verifymyidentity to access the Identity Verification Service tool.
2. Please have your notice, a copy of your tax return, and personal financial information readily available.
3. Answer security questions based on your financial history and account information.
4. Complete verification immediately to resume return processing.
5. Utilize the Where’s My Refund tool on IRS.gov after verification to track your refund status.
For Letter 4883C (Phone or Online Verification)
1. Please call the toll-free number listed on your notice during business hours.
2. Provide information to verify your identity over the phone with an IRS representative.
3. Alternatively, use the online Identity Verification Service tool at IRS.gov/verifymyidentity, if available.
4. Keep your notice, tax return, and financial records accessible during the call.
5. Request verbal confirmation that verification is complete before ending the call.
In-Person Verification Requirements
Letter 5747C requires you to schedule an appointment at an IRS Taxpayer Assistance Center.
Please call the number on your notice to schedule an appointment during our available hours.
You must bring original or certified copies of specific documents to your appointment.
Required documents for in-person verification include one government-issued photo ID such as a driver’s license, state ID card, passport, or military ID. You must also bring your original Social
Security card or a letter from the Social Security Administration showing your Social Security
number. Provide proof of your current address with a document dated within the past 12 months, such as a utility bill, bank statement, mortgage statement, or lease agreement. Tax returns and W-2 forms are generally not accepted as proof of Social Security number ownership at Taxpayer Assistance Centers.
The IRS will not accept expired photo identification documents. Ensure your government-issued
ID is up to date before attending your appointment. Please bring all required documents to avoid rescheduling and further delays in your return processing.
Identity Theft vs. Identity Verification
Identity theft notices and identity verification notices serve different purposes and require different responses. Identity verification notices request that you confirm your identity when the
IRS detects unusual activity, but it has not confirmed that theft has actually occurred. Identity theft notices address the confirmed or suspected fraudulent use of your Social Security number by another person.
If you receive a notice specifically stating someone else filed using your information, you must complete Form 14039, the Identity Theft Affidavit. Form 14039 is required in addition to or instead of standard identity verification procedures. Professional assistance is strongly recommended when responding to confirmed instances of identity theft.
Actions That Harm Your Position
Missing response instructions or deadlines will result in an automatic account lockdown, preventing filing or refund processing until a response is provided. Submitting incomplete information during online or phone verification requires you to repeat the process, which delays the return processing. Failing to bring all required documents to an in-person appointment may result in rescheduling and further processing delays.
Assuming verification is complete without confirmation from the IRS means that your return will not be processed. Ignoring follow-up notices or additional requests prevents account unlocking and may trigger collection action if you owe taxes. Providing information that does not match
IRS records flags your account for potential investigation into fraud.
What Happens After Verification
After you complete identity verification online, by phone, or in person, the IRS resumes processing your return. For online verification using Letter 5071C or 4883C, you receive
on-screen confirmation when verification is complete. For in-person verification using Letter
5747C, you receive confirmation at your Taxpayer Assistance Center appointment.
The IRS does not provide a uniform timeframe for sending written confirmation of successful verification or for issuing refunds after verification. Processing and refund timelines vary by individual circumstances and the IRS's processing volume. You can check your refund status using the Where’s My Refund tool on IRS.gov or the IRS2Go mobile app after completing verification.
When Professional Help Becomes Critical
Seek professional assistance when the IRS requests documents you cannot locate or do not possess, such as an original birth certificate or a lost Social Security card. Professional help becomes critical when your identity verification notice references identity theft or fraudulent filing in your account. You should consult a tax professional if you received multiple identity verification notices over several years, if your identity verification is tied to an active collection case or wage garnishment, or if you need representation at an in-person IRS appointment.
Many taxpayers successfully respond to identity verification notices independently by carefully following the instructions provided in the notices. Professional guidance provides the most value when documents are missing, multiple notices were issued, or identity theft is confirmed.
