Mastercard has launched Account Range Enablement (ARE), a transformative digital solution designed to streamline and modernize the registration of account range data. Traditionally, users were required to register individual Primary Account Numbers (PANs), a process that was both time-consuming and operationally intensive. ARE enables the updating of entire account ranges in a single step, significantly accelerating onboarding and reducing manual overhead.  

ARE introduces strategic flexibility, users can now dynamically manage pricing tiers and product eligibility, aligning more easily with Mastercard's commercial flexible interchange Pricing Program. This capability supports faster market entry and better regional pricing alignment.

#### Following are the execution steps: {#following-are-the-execution-steps}

1. The customer updates the account range along with the associated product for registration using the `PUT /account-ranges` API endpoint.
2. The Account Level Management (ALM) validates the account range and product, then updates the account range in the system.
3. The API response is provided to customers with the updated account category code, accept codes or reject codes as applicable.
