Visa provides updates about migration to the eight-digit BIN
For: All merchants
Date effective: April 2022
Background
In 2017, the International Organization for Standardization announced a new standard for the migration of the payments infrastructure from the current six-digit Issuing Identification Number (IIN) to an eight-digit standard, to help ensure an adequate global Bank Identification Number (BIN) supply for the industry.
Effective in April 2022, Visa will implement eight-digit issuing BINs in accordance with this transition. Visa will only assign eight-digit BINs after the April 2022 release date.
Considerations
Systems accepting only six-digit BINs must be updated for eight-digit BINs. Consider how this change may impact your systems, including POS systems. Please follow the current global BIN file specifications and review your internal processes to ensure you are prepared to accommodate an eight-digit BIN.
In preparation for expanding to the new eight-digit BIN standard, migration can be simplified by efficiently managing the numeric capacity in existing six-digit BINs. This means using the identification and processing capabilities that exist at the account range level. Each six-digit BIN contains 1,000 discrete account ranges, and can support multiple products/programs, as permitted for certain product types in the Visa Rules. Visa expects compliance with existing policies that require the ability to process and manage products at the account range level.
Clients must ensure their vendors, agents, and third parties are involved in preparation and testing activities for adoption of the eight-digit BIN.
Numerics terminology changes
Visa has several numeric identifier values used for processing, routing, and identification within the payments ecosystem. Visa will consolidate identifier names and, in some cases, rename to clarify usage with the conversion to an eight-digit issuing BIN. Visa will use the term “BIN” solely to refer to the six- or eight-digit PAN prefix used to identify the issuer licensee. Visa-assigned numeric identifiers used for processing, historically referred to as “BINs,” will be renamed using terminology specific to each of their functions.
Starting in fourth quarter 2019, Visa documentation will be updated to use the future identifier names shown in the table below.
Identifier name | Description | Format | ||
Future | Current | Future | Current | |
Primary Account Number (PAN) | Primary Account Number (PAN) | Used for identifying different processing characteristics. | 16-digit, numeric1 | 16-digit, numeric1 |
Account Range | Account Range | First nine digits of the PAN used to identify various product and processing attributes. | Nine-digit, numeric | Nine-digit, numeric |
Acquiring Identifier | BIN, Acquiring BIN, Acquiring Institution Identification Code, Affiliate ID, Acquiring Route Identifier (RID), RID, Acquiring ID | Assigned by Visa to identify the acquirer. | Six-digit, numeric | Six-digit, numeric |
Issuing Identifier | Primary Account Number (PAN) | Assigned by Visa and used to define issuing processing. Multiple issuing (ISO) BINs may use the same issuing identifier. | Six-digit, numeric | Six-digit, numeric |
VSS Processor | BIN, Processor, Settlement BIN | Used to define the settlement entity for V.I.P. Full Service endpoints. | Six-digit, numeric2 | Six-digit, numeric2 |
BASE II Center Information Block (CIB) | BIN, Processor BIN, CIB | Used to define the processor/settlement entity for BASE II endpoints. | Six-digit, numeric | Six-digit, numeric |
File Deliver Endpoint Identifier | Non-core numeric identifier (NCNID) | Used to identify a specific endpoint. | Six-digit, numeric | Six-digit, numeric |
Issuing (ISO) BIN | BIN, Issuer Identification Number (IIN), ISO BIN, Card Prefix | Identifies the issuer. Same as first digits of PAN. Rarely used in Visa processing. | Eight-digit, numeric3 | Six-digit, numeric3 |

Visa Resolve Online Identifier | Routing ID | Used to identify various Visa Resolve Online organizations, enabling endpoint access to specific disputes. | 11-digit, numeric | Six-digit, numeric |
Encryption rule identifier | BIN, Encryption BIN, Pseudo BIN, Routing ID | Used as a Visa system locator to ensure correct keys are associated with a given entity. | 11-digit, numeric | Six-digit, numeric |
119-digit PANs are used for V PAY in Europe.
2The length will be 10 digits when a four-digit network identifier is included.
3Existing BINs will remain six digits unless and until an issuer chooses to migrate them to eight digits.
