ReferralCode is an online community and search platform for discovering and sharing referral codes, promotional offers, and refer-a-friend links. It helps people find ways to save money or earn rewards through word-of-mouth recommendations, while giving members a place to share their own codes and invite friends. The service is free to use and features search tools for browsing offers by brand, category, or country, alongside featured brands and recently added codes.

Listings span a wide range of areas, including shopping, travel and transport, banking, money transfers, cryptocurrency, betting, and gaming. Offers may include discounts, welcome bonuses, credits, free rides, or other rewards, with details and eligibility conditions provided by the users who submit them. Members can add referral codes, suggest new brands, and explore verified listings that display information such as usage, clicks, and recent activity. ReferralCode also provides guidance on how the platform works, FAQs, account access, and contact information. By bringing referral offers together in one searchable destination, it aims to make sharing recommendations and finding promotions straightforward.
