What Are Coupon Codes?

A coupon code (also known as a promo code or discount code) is a combination of letters, numbers, or symbols that consumers can enter during checkout to receive a specific discount or offer. These codes may provide:

Percentage discounts (e.g., 20% off)

Fixed amount discounts (e.g., ₹500 off)

Free shipping

Buy One Get One (BOGO) deals

Access to exclusive products or services

History of Coupons

Coupons have been around since the 1880s. Coca-Cola was the first company to distribute paper coupons to promote free samples of its soft drink. Over the years, paper coupons evolved into digital formats, leading to the rise of promo codes used in eCommerce.
