A GCN number is an identifier that enables companies to retrieve information associated with a coupon from a database.
According to the provided reference, the GCN (likely standing for Global Coupon Number or similar) serves as a key to accessing coupon details. Here's a breakdown of its function:
-
Retrieval of Coupon Information: The primary purpose of the GCN is to allow businesses to quickly and accurately pull up coupon-related data stored in a database.
-
Specific Uses: The retrieved information is used for several vital tasks, including:
- Validity Checks: Confirming that the coupon is genuine and hasn't expired.
- Offer Conditions: Accessing the terms and conditions attached to the coupon offer (e.g., eligible products, minimum purchase requirements).
- Redemption Status: Checking whether the coupon has already been used to prevent fraud or double redemption.
In essence, think of the GCN as a unique serial number for a coupon, allowing for efficient management and tracking within a digital system. It standardizes how coupons are identified and validated across different platforms and retailers.
