Numerics Initiative Reminder: Timing for BIN Prefix Sharing
Regions: US, Canada, AP, CEMEA, LAC, EUROPE
28 February 2023
Visa chose to hold reassignment of eight-digit BINs returned prior to April 2022 for at least a year following the adoption of the new eight-digit BIN standard. This was to give the ecosystem time to carry out any remaining system development needed to support this global industry change.
Visa is reminding payments ecosystem participants that they may begin seeing eight-digit BINs with the same six-digit prefix across different issuers and product lines as early as April 2023. Entities currently only reading to the sixth digit on BIN tables to make authorization and other decisions will need to update their systems by April 2023 to read out to the eighth digit, at a minimum, to prevent potential impact.
