Finding out the folio number

Long time around back, around 10 years, my dad bought some physical shares of Allahabad Bank. Now the share certificate is lost and he’s doesn’t have any idea about folio number and dividend payout. Is there any way through which I can find out the folio number so that I can apply for duplicate certificate.

Assuming PAN might have linked to the investments. Can using PAN, if you register on CDSL . It should show all investments.

OR try the steps mentioned in

Thanks for the info. I will see if I can find out from their website. But I think Allahabad Bank is not listed now. Its price tanked.
