A registrar is an authorized retailer of domain names. In order to be able to offer domain names for registrations, Registrars must be certified by ICANN. Registrars charge customers retail prices for domains and then pay the domain registry the difference. In addition to domain names, most registrars offer additional services like website hosting, website building, eCommerce stores, email, Internet marketing, and other value-added services.
