Frazao Auctions is a Lisbon-based auction house specializing in philately. Founded in 2023 by Luís Frazão and his son, Marco Frazão, the company brings collectors together through regular auctions and a direct-purchase shop. Its offerings cover a broad range of philatelic material, including stamps, covers, postal history, cancellations, picture postcards, philatelic literature, collections, and albums. The firm has a particular focus on Portugal and its former colonies, while also seeking to expand its selection of material from other countries to serve Portuguese and international clients.

Frazao Auctions provides services beyond buying and selling. Collectors can request valuations and assistance with the formal certification process for philatelic items. Auctions are presented in multiple parts and may include live and online bidding or online-only formats; completed auction results are also available on the site. Prospective bidders can register to participate, and the company invites visitors to subscribe to its newsletter for updates about new offerings and upcoming sales.
