How Do You Activate Your Subway Card?

A customer can activate the Subway card either in-store or online at, depending on the purchase method. Cards bought at Subway restaurants or at specific retailers, such as Walmart, are activated when purchased.

When a customer purchases a Subway card online, he must activate it when it arrives in the mail by visiting the website and entering the card number in a registration form. Cards that are already activated can still be registered online to enter the Subway rewards program, which earns the cardholder a point for every dollar spent at the restaurant. The points can then be used for food items.
