Temporary Phone Number for Whatnot

Updated 3 min read

Whatnot won't let a bid or a live sale go through until the account's phone number is SMS-verified. Grabbing an additional virtual number for that one step is a practical option when bidding from abroad or keeping a live-shopping account on its own number. 5SIM has available Whatnot numbers, delivers the SMS online, and keeps the order in your dashboard.

Whatnot runs shopping as live video. A seller goes on air, holds each item up to the camera, and viewers bid in real time or buy at a set price, with payment and shipping handled inside the app. Shows run on their own rhythm, quick auctions, giveaways to viewers, and a chat that moves fast. It started with trading cards and collectibles and now covers sneakers, comics, electronics, vintage clothing, and sports memorabilia.

The format is growing fast. In the first half of 2026, Whatnot passed the 8 billion dollars in gross merchandise value it took all of 2025 to reach, and it signs up about 650,000 new users a week. The number of sellers past a million dollars in lifetime sales more than doubled over the year, and the company says it holds close to 60% of a live-commerce market worth more than 22 billion dollars.

Investors have kept pace. An August 2026 round raised 545 million dollars and set the valuation at 20 billion, nearly double the figure from ten months earlier. Whatnot has launched in the UK, several European markets, and Australia, and plans AI tools that help sellers write listings and read their sales data.

Creating an account takes an email or a phone number, and Whatnot confirms a number by SMS before an account can bid or sell, part of keeping fake buyers out of live auctions. Someone who would rather keep bid and shipping alerts off a personal line can register with an additional virtual number and read the SMS in a 5SIM order.
