8-Digit BINs are coming: Ensure you’re ready with PaySim

Mastercard and Visa are moving from 6-digit BINs to 8-digit BINs for prepaid, debit and credit cards in the coming months. Both Visa and Mastercard have confirmed that from April 2022, they will no longer be issuing 6-digit BINs. 

With the timing running out, have you tested your cards and payments system are compatible? 

What happens if it goes wrong? 

  • Incorrect routing and authorisation failures 
  • Unexpected BIN fees / monthly management fees 
  • Settlement and clearing failures 
  • Host card management system, affiliate bank processing, reporting failures 
  • Incorrectly split portfolios across consumer and commercial 

The impact of 8-digit BINs  

The change to BIN will impact acquirers, issuers and processors.  Affected systems may include  

  • ATMs 
  • POS devices and terminal 
  • Switches 
  • Authorisation and settlement systems 
  • Data analytics and reporting systems 

Payment companies and services providers should be testing their systems to ensure they can acquire, issue and process transactions from cards with 8-digit BINs.
