ARN plays a key role in refund tracking and resolution:
Meaning of ARN
An Acquirer Reference Number or ARN is a unique identification code assigned to a credit or debit card transaction especially on major card networks like Visa and Mastercard. This happens once it has been processed by the acquiring bank (the merchant’s bank) and forwarded through the payment network.
Each ARN typically consists of a distinct long string of digits that is recognised by both the issuing bank (your bank) and the acquiring bank (merchant’s bank). It essentially acts like a tracking number that enables the transaction’s movement to be followed across different banking systems from the point of purchase or refund initiation to the final settlement.
This number improves transparency and traceability of online payments and refunds, which can otherwise be difficult to pinpoint as they pass through multiple intermediaries.
How to Obtain the ARN
You can get the ARN once a refund has been processed by the merchant’s payment system. Typically, after the merchant initiates the refund with their acquiring bank or payment gateway, an ARN is generated within a short period (often within 24–72 business hours). To obtain it:
Ask the merchant directly: Merchants or sellers can usually provide you with the ARN once the refund has been raised with their payment processor.
Contact your card issuer: You can also request the ARN from your bank or credit card provider; they can look up the reference code associated with your refund transaction.
Once you have this ARN, you can use it to follow up with your bank or payment provider to check where the refund currently stands within the banking network.
How ARN Helps Track Refunds
The ARN is extremely useful when a credit card refund is delayed or not showing up in your account. Because it is recognised by banks across the payment network, your issuing bank can use the ARN to locate the exact point at which your refund is in the processing chain—whether it’s still with the merchant’s bank, with the card network, or with your own bank.
By providing the ARN to your bank or card issuer, they can:
Trace the refund across systems: Banks can follow the refund’s path through various intermediaries to find out where it may be held up.
Resolve delays or errors: If the refund hasn’t reached your account on time, your bank can use the ARN to investigate and fix issues, such as routing errors or processing bottlenecks.
Confirm completion: The ARN helps confirm whether a refund was successfully processed and provides clearer evidence of the transaction’s status.
