Whatnot is one of the fastest-growing live shopping platforms in the world. Known for its high-energy livestream auctions, Whatnot connects buyers and sellers of collectibles in real time — including trading cards, sneakers, Funko Pops, comic books, sports memorabilia, vintage items, and a wide range of niche collectible categories. The platform has become especially popular among collectors who enjoy bidding during live streams, claiming items instantly, and interacting with sellers face-to-face through video.
Whatnot allows creators and sellers to host live auctions, set up shop pages, manage inventory, print shipping labels, and build communities around their collections. For buyers, the platform offers fast purchases, verified sellers, buyer protection policies, and an engaging, entertainment-driven shopping experience. Because Whatnot involves real-money transactions, identity authentication, financial payouts, and community interactions, maintaining security is critically important.
This is why Whatnot may require phone number verification when users create an account, apply to become a seller, or attempt to bid in auctions. Verifying phone numbers helps the platform ensure that users are legitimate and reduces fraud — particularly important in high-value collectible markets.
However, many users prefer not to verify Whatnot using their personal phone number. Some may want an added layer of privacy, others create multiple accounts for buying and selling, and international users often face barriers receiving SMS from U.S. services. In these cases, a temporary virtual phone number from 5SIM provides a fast and secure way to receive verification codes without exposing your real number.
As a marketplace combining live entertainment with financial transactions, Whatnot needs to ensure user security and platform integrity. Phone verification plays a central role in preventing fraudulent activity and maintaining trust between buyers and sellers.
