What Is a PAN Bank Account Linkage Check?
A PAN bank account linkage check tells you whether a submitted Permanent Account Number and bank account appear linked in the available information.
Banks hold a PAN against the accounts they open. Later processes then assume the account receiving the money belongs to the person whose PAN is on the file. Where the two are not linked, that assumption fails quietly, usually at the payment.
Running a PAN and Account Linkage Check Through an API
An API puts the check inside the flow that already holds both values, instead of leaving it to a failed credit or a reconciliation list.
Your application submits the PAN with the bank account details, and a linkage status comes back in a structured response.
The value shows at volume. One broken file can be sorted out by hand, while a payout run of several thousand cannot.
What You Send: A PAN and a Bank Account
You send a pair your workflow already holds: the PAN, and the bank account it is checked against. That normally means the account number and the IFSC that identifies the branch.
Both come from your own customer file, covered by the consent and authorization your relationship rests on. The fields available may vary with the data source and the record, and the scope of a response depends on the selected service contract.
Linkage Check, Account Verification and Name Match
Three questions get run together at payout time, and they are easy to confuse.
Account verification asks whether an account exists and can receive a credit. Penny Drop answers that by depositing a nominal amount and reading back the name the bank holds against it. Penny Less answers a similar question without moving money.
A linkage check asks something narrower: whether that account and the submitted PAN appear associated in the available information. It does not confirm identity, verify either value on its own, or describe the balance or state of the account.
Teams paying out at scale usually run both. The account has to be reachable, and it has to belong to the person the file is about.
Who Runs a PAN Linkage Check
- Lending and NBFCs check the disbursal account against the applicant's PAN before release, so a mismatch surfaces while the file is still open.
- Fintech and payment platforms check a merchant's settlement account at onboarding, before settlement instructions are set up.
- Insurers check the claimant account ahead of a settlement that will be reported for tax.
- Marketplaces, staffing and gig platforms check seller and worker accounts before a payout run, where one mismatched record can hold up a batch.
- Enterprise finance teams check a vendor account before the first payment against a new master record.
How to Check PAN and Bank Account Linkage Online
- Collect the PAN and the bank account details on the same customer file.
- Confirm that consent and an authorized business purpose cover a check on both.
- Submit the pair through the API.
- Read the returned status, and send a mismatch to review.
- Ask the customer to correct the record, then re-check before the payment goes out.
Where the Linkage Check Sits in Your Payout Flow
Place the check before the first payment. A mismatch found while the customer is in the flow is a correction. The same mismatch found at disbursal is a reversed credit, a support ticket and a re-run.
Treat an inconclusive result as its own outcome. Records update on their own schedule, and a gap in the available information says nothing against the customer.
Keep the status with the file it justified, and re-check whenever a customer changes the account they want to be paid into.
Consent Rules for a PAN Linkage Check
A PAN and a bank account are both personal information, and relating them is more sensitive than reading either alone. Run the check only for customers you already hold a relationship with, for a purpose they were told about, with consent and authorization recorded.
Keep consent specific and revocable. Limit access to the team whose work needs it, and keep the status only as long as that purpose requires. Where a status affects something the customer experiences, such as a held payout, give them a route to correct their records.
