Hi,
I have got this article from The Economic times, just go through this... This may help you
How to Merge 2 UAN Accounts:
You need to notify your current employer or write to the EPF to get the previous UAN blocked and the existing balance transferred to the active UAN. The employee must file a claim to have the EPF account connected to the blocked UAN transferred to the active account. To resolve the issue, the EPFO will conduct a verification. Send an email to [Login to view] with your present and previous UAN in the subject line. This process can be time-consuming.
The old UAN is deactivated by transferring the funds to the new one. After the transfer request, EPFO verifies the transfer claim. Both the UANs are linked and EPFO will deactivate the old UAN once the transfer process is done. The process of UAN merging will be completed automatically. Once EPFO verifies your new UAN, it will be linked with your PF account.
The second method for deactivating one of the UANs is automatic, and it will take less time than the above-mentioned method.
Step 1: Visit the EPFO portal
Step 2: Enter using your documents
Step 3: On the menu bar, Click on 'Claim'
Step 4: Click on "Request for Transfer of account" to file an online Transfer Claim
Step 5: Enter Captcha and click on "GET PIN"
Step 6: After entering the PIN obtained on the registered smartphone, the online claim application can be submitted.
It is worth noting that when a request for EPF transfer is made, the EPFO device automatically detects the duplicate UAN. The old UAN from which the funds are being transferred will be deactivated once the identification process is completed. The old EPF account will be linked to the new UAN once the UAN is automatically deactivated. You will receive an SMS informing them of the old UAN's deactivation status. In case you have not yet activated the new UAN, you will be sent an email with instructions on how to do so.
