Referral.is is a community-driven directory for discovering and sharing referral codes, referral links, and invite offers for apps and services. It brings together submissions from real users and organizes them into searchable listings, curated collections, and featured offers. Visitors can explore opportunities across finance, banking, credit cards, travel, cashback, food delivery, money transfers, shopping, crypto, gaming, and technology.

Each listing highlights available program details, such as potential rewards, eligibility, and relevant terms. Examples include offers associated with PayPal, Remitly, Hilton Honors American Express, ZA Bank, and SoFi. Because benefits and requirements vary by program, Referral.is encourages users to check current terms on the destination site before signing up or using a code.

The site also publishes guides explaining referral codes and how to assess offers, alongside frequently asked questions and collections of popular services. Users can submit their own codes or invite links to share with others. Referral.is describes its goal as making referral offers easier to find and review, while noting that rewards depend on each program’s rules and eligibility conditions.
