With Cashfree Payments, you can do verification for any number of PAN via two modes:

  1. Via Dashboard 
    You can use the dashboard to not only do single PAN verification, but you can also download the sample template, add PAN of users and upload the file and get instant response for upto 10,000+ PANs at a time. 
  2. Using API
    This is an integrated automated way to do bulk verification. The API can be integrated with existing company internal systems or ERP and then requests can be pushed directly using API.
