The members have to understand that they get this error because of a wrong name registered with their EPFO database, so they have to update their name entered in EPF UAN Portal first.
In order to update/correct the registered name in EPFO database, the only thing is to fill & submit EPF Joint Declaration Form.
This Joint Declaration Form is so useful that a single form can also be used to update some other details like:
While filling the EPF joint declaration form, the member has to mention his/her wrong as well as the correct name. After that, the member should take that form to his/her employer for the attestation process. Then submit the attested form along with the employer's name correction request letter to your regional EPF office. The time period to update the same is at least 30 days.
Sometimes, PAN card details can also be wrongly updated. If that happened, then the members have to correct his/her name mentioned on his PAN card.
