Where is the service code found and what is its purpose?

• A. In the magnetic-stripe data; it defines issuance rights
• B. In the magnetic-stripe data; it stores the cardholder's name
• C. In the magnetic-stripe data; it is a three- or four-digit value that defines service attributes, differentiates interchange, or identifies usage restrictions
• D. In the magnetic-stripe data; it identifies the card brand

Answer: (C)

The service code is stored in the magnetic-stripe data and appears as a three- or four-digit value. Its purpose is to convey how the card may be used: it defines service attributes, helps differentiate interchange rules, and identifies any usage restrictions that apply to processing transactions. This code guides the payment system on what is allowed or restricted for the card, such as whether cash access is permitted or if international use is restricted. It is not used to store the cardholder’s name, nor to identify the card brand, and it does not define issuance rights.
