Finding Issuer BINs for Alert Troubleshooting

This article applies to merchants who need an issuer BIN for Chargeback.io Support to troubleshoot missing Verifi or Ethoca chargeback alerts.

This article doesn't explain how to find acquiring BINs for activating Rapid Dispute Resolution (RDR) chargeback alerts.

Sometimes Chargeback.io Support will ask for an issuer BIN when investigating why a chargeback alert didn't reach your account. Without the issuer BIN, Verifi and Ethoca cannot review the issuing bank details tied to that transaction.

An issuer BIN is the first 6 digits of the customer’s card. It identifies the bank that issued the card. Use issuer BINs only for troubleshooting missing alerts.

If you need to connect your account to Ethoca or Verifi for RDR, then use your acquiring BINs instead. For that process, use the guide for finding BINs and CAID.

This section explains whether you can get issuer BINs from your payment processor. It will also tell you how to find them in popular platforms.

If you use a payment processor other than Stripe or Shopify, check details of the transaction connected to the disputed transaction. You will need to look for the first 6 digits of the customer's card number.

If you can't find the issuer BIN in your transaction's details, ask your processor's support team if they can provide it. Though, most processors will not provide it.

Stripe doesn't provide issuer BINs because of PCI DSS rules.

This section explains how to find issuer BINs in Shopify Payments.

Step 1: Open the transaction timeline.

Step 3: Click “Information from the gateway.”

Step 4: Find the BIN

Step 5: Copy the issuer BIN or IIN and send it to a Chargeback.io Support.
