Service Code

The Service Code is a critical component of the magnetic-stripe data encoded on payment cards, serving as a numerical indicator that conveys important information about the card's attributes and usage parameters. Typically consisting of three or four digits, the Service Code is positioned following the expiration date within the track data on the magnetic stripe of a payment card.

The Service Code plays a multifaceted role in the processing and authorization of payment transactions, encompassing several key functions:

The Service Code serves as a critical reference point for payment processing systems and stakeholders involved in the authorization, routing, and settlement of payment transactions. By interpreting the information encoded in the Service Code, merchants, acquirers, and card issuers can make informed decisions regarding transaction acceptance, routing optimization, and risk management.

It's important to note that while the Service Code provides valuable insights into the attributes and parameters of a payment card, it does not include sensitive authentication data such as the cardholder's account number, CVV/CVC, or PIN. Consequently, the Service Code contributes to the security and efficiency of payment processing by facilitating the proper handling and routing of payment transactions while safeguarding sensitive cardholder information from unauthorized access or misuse.
