Changing mobile linked to epfo account

Hello Friends,

I have a PF account that has been inactive for the past 7 years. My account includes both employee and employer contributions for 10 years, and I also have a UAN number. I moved to the USA for a project and am unable to access my PF account through the portal, as I no longer have access to my old mobile number. I thought updating my Aadhaar, since it’s linked to the PF account, might help. I’ve updated my Aadhaar with a new mobile number, but it’s been almost 4 days, and the ePFO portal is still sending the OTP to my old mobile number. I’m not sure if the Aadhaar and PF accounts are linked or not.

Could anyone clarify:

1. How long does it usually take for the mobile number update in the Aadhaar system to reflect in the PF system?
2. Is it possible that the Aadhaar update won’t automatically propagate to the PF system? Do I need to visit the PF office to update it manually?

Any suggestions or advice given my situation would be greatly appreciated.

Thanks

Sunder
