  • CAID pattern issue
    If banks use inconsistent CAID patterns, verify the correct pattern with the bank.
  • Multiple descriptors
    Collect each BIN and CAID combination descriptors to ensure accurate enrollment.
  • No traffic on MID
    Confirm any traffic on the MID with the merchant. If there is traffic, it’s necessary to obtain VISA ARNs of the latest chargebacks or transactions, which should be no older than 120 days. The second digit of VISA ARNs must be 4, and an ARN should have 23 digits. Without ARNs, there is a risk of enrolling an incorrect combination.
  • Shared acquirer BINs/CAIDs
    If sharing a BIN/CAID with another entity outside your business network, contact support team for help with enrollment in services such as Ethoca/CDRN.
