How to Fix UAN Mismatch and Aadhaar Errors During EPF Form 10D & Death Claims (2026 Guide)

Filing a Monthly Pension Claim (Form 10D) or a Death Claim on behalf of a deceased member (Form 20) involves the most stringent verification protocols in the entire Employees' Provident Fund Organisation (EPFO) ecosystem. Because these claims deal with lifelong payouts, widow/orphan pensions, and high-value beneficiary disbursements, the Unified Portal's backend algorithms are unforgiving toward data discrepancies.

If you or your nominees are attempting to file these critical settlement forms, you will likely encounter one of two hard-stop portal errors: “Requested UAN does not match with the Primary UAN” or “Member AADHAAR is not Verified.” Here is a technical breakdown of exactly what these two errors mean, why the EPFO 3.0 system is blocking your application, and the step-by-step statutory resolution process for both members and nominees.

Error 1: “Requested UAN does not match with the Primary UAN”

This error is the direct result of fragmented employment history. Over the course of a career, if you switch jobs and there is a slight spelling error in your name or a missing exit date from your previous company, your new employer's portal will fail to link your existing Universal Account Number (UAN). Instead, the system automatically generates a brand-new, duplicate UAN for you.

How to Resolve the UAN Mismatch (De-Duplication Process)

1. Identify the True Primary UAN: Log into the EPFO Member Portal. Navigate to View → Service History. The UAN that successfully lists your latest active employment is your Primary UAN. Make a strict record of all other secondary UANs.
2. Initiate an Online Transfer (Form 13): If you have active login access to both UANs, you must merge the accounts. Go to Online Services → One Member - One EPF Account (Transfer Request). Initiate a transfer of funds and service history from the old UAN(s) to the Primary UAN.
3. Offline Deactivation of Duplicate UANs: If you cannot log into the old UAN (usually due to a lost phone number or KYC block), you must escalate the issue for manual de-duplication. Send a formal email to your jurisdictional EPFO Regional Office or file a targeted grievance on EPFiGMS with the subject line "UAN Deduplication/Merge Request." Provide your Aadhaar, PAN, and a list of all UANs, explicitly requesting the department to deactivate the older UANs and map the previous Member IDs to your Primary UAN.
4. Re-file the Claim: Once the transfer is settled and the service history reflects accurately under the single Primary UAN, you can successfully re-file Form 10D or Form 20 without triggering the mismatch error.

Error 2: “Member AADHAAR is not Verified”

Under Section 142 of the Code on Social Security, the EPFO operates on a strict UIDAI-first compliance model. If a member’s Aadhaar is not digitally seeded and cryptographically verified against the EPFO master ledger, the portal will instantly freeze all outward claims—especially high-risk transactions like widow pensions and Employees' Deposit Linked Insurance (EDLI) settlements.

How to Resolve the Aadhaar Verification Error

For Living Members (Filing Form 10D):

1. Log into the UAN portal and check your demographic details under View → Profile.
2. If your Name, DOB, or Gender differs from your Aadhaar card, you must file an online Joint Declaration (under the Manage tab) to overwrite and correct the EPFO master records.
3. Once your ex-employer and the Regional Office approve the correction, navigate to Manage → KYC, input your Aadhaar details, and allow the system to auto-verify it via the UIDAI database. You can then file Form 10D digitally.

For Nominees Filing a Death Claim (Form 20, 10D, and 5IF):

1. If the deceased member's Aadhaar was not verified prior to their death, nominees cannot fix this online. The digital signature routing for online KYC requires a living member's Aadhaar-linked OTP, which is legally void after death.
2. The nominee must bypass the portal entirely and submit a physical, offline Composite Death Claim Form to the EPFO Regional Office where the last employer was registered.
3. This physical docket must include a meticulously compiled evidence file: the deceased’s Aadhaar copy, the original Death Certificate issued by the municipal authority, the nominee's Aadhaar and PAN, cancelled cheques, and an offline Joint Declaration.
4. The offline Joint Declaration must be physically stamped and signed by the final employer (or a Bank Manager/Gazetted Officer if the company is closed) certifying the true identity of the deceased member and bridging the demographic mismatch.
