What is a voucher code?

A voucher code is a combination of letters or numbers that can be used to redeem a discount or special offer on a product or service. Voucher codes are often distributed by businesses as a promotional tool to encourage customers to make purchases and to reward loyal customers. They can usually be entered during the checkout process online or presented in-store at the time of purchase. Voucher codes typically have an expiration date and may have restrictions or limitations on use, such as a minimum purchase amount or a limited availability of use. Some voucher codes are one-time use only, while others can be used multiple times.
