Struggling to Link My Old EPF Scheme Certificate to Current UAN Before Pension Application?

I have a scheme certificate from my past employer, which was issued in the year 2002. In 2002, after a gap of 6 months, I took employment in the present company. When I left the first company, I had taken out my PF amount, but because of 10 years of service, I received the scheme certificate. My past employment (1992-2002) does not have a UAN nor is it Aadhar linked.

I will turn 58 in a few months. In my present member login against UAN, I can only see my current employment details in past service details.

Attempts to Add Previous Employment

I have tried the following to add my previous employment:

1. I tried to use the transfer request - One member one account function in the member portal, but the system is asking to generate UAN for the old member ID.
2. When I try to generate UAN for the earlier ID, it says data mismatch. Contact the previous employer.

Question

Do I need to do anything to add my previous employment to the current UAN before submitting my 10D pension application?

Or do I just upload my scheme certificate while applying for 10D online? (There is a provision for uploading the scheme certificate.)

Hi, at the time of joining a new employer, you are required to submit the scheme certificate to them. The new employer should then submit your EPS scheme certificate and Form 11 to the respective PF office, enabling them to transfer the amount to your new PF Account. Please contact your former employer to assign a new UAN for you. Do not upload your scheme certificate online as you need to combine both the old and current pensions (if applicable).
