## What the PAN Aadhaar Link Lookup API does

PAN Aadhaar Link Lookup returns the linkage status and, in addition, the masked Aadhaar number associated with the PAN.

The masked number lets you confirm which Aadhaar is linked without ever handling the full value, so you can reconcile against a customer's declared Aadhaar while keeping your data footprint minimal.

## Where teams use the PAN Aadhaar Link Lookup API

1.  Confirming which Aadhaar is linked to a PAN
    
2.  Reconciling a declared Aadhaar against tax records
    
3.  Checking linkage without handling full Aadhaar numbers
    
4.  Detecting mismatches between declared and linked identity
    

## Frequently Asked Questions (FAQs)

Why masked rather than full?

The last four digits are enough to confirm which Aadhaar is linked, and avoiding the full number keeps you clear of unnecessary handling obligations.

What does a mismatch mean?

The customer supplied a different Aadhaar from the one linked to their PAN. Worth investigating before proceeding.

When should I use the plain status endpoint?

When you only need to know whether linkage exists, not which number is linked.
