How to verify a Whatnot account with a temporary number

By the Noir SMS team3 min read

Quick answer

Whatnot sends an SMS code when you create an account. A temporary number from Noir SMS can receive that code; UK numbers are in good stock for Whatnot right now. A temporary number is for the sign-up check only: if you plan to sell, Whatnot asks for identity and payout details that must be your own.

Whatnot is a live-shopping marketplace for collectibles. You can browse streams with just an account, and that account starts with a phone check. This guide covers how to pass that step with a number from Noir SMS, and where a temporary number stops being useful.

Which country to choose

Check the Whatnot service page: the live price and stock differ by country and move during the day. UK stock for Whatnot is deep on Noir SMS and its price is among the lowest for the service, so it is a sensible first try, even if you live elsewhere. If the app rejects the number, try the United States next.

What the phone number is used for

Whatnot uses the number to confirm you are a person and to reduce duplicate accounts. Order and stream notifications can also come by SMS if you leave them on. Because a Noir SMS number is receive-only and expires after 20 minutes, turn off SMS notifications and use email and push instead.

Step by step

  1. Choose the countryOn the Whatnot page of Noir SMS, check the live price per country and pick one with stock.
  2. Buy the numberAdd funds from $5, then buy one number. The number appears in your dashboard.
  3. Enter it in WhatnotType the number with its country code at the phone step and ask for the SMS code.
  4. Confirm and secure the accountEnter the code from your dashboard, then add an email and a strong password and turn off SMS alerts.

Buying and selling are different

Browsing and bidding need only a verified account. Selling asks for more: identity details, a payout method and often tax information. These must be yours and real, and a temporary phone number cannot stand in for them. Do not use a temporary number for an account you intend to get paid on.

When no code arrives

Some apps delay the SMS on the first try. Wait a minute, request again once, and if nothing arrives cancel the order after 2 minutes. You are refunded automatically at the latest after 20 minutes. Do not keep requesting codes; too many tries can lock the number for a while.

Frequently asked questions

Does Whatnot accept temporary numbers?

Many carrier mobile numbers work. A number can still be refused if it has been used before, and then you cancel for a refund.

Can I sell on Whatnot with a temporary number?

The sign-up code, yes. Selling requires your own identity and payout details, so do not rely on a temporary number for that.

Which country is cheapest?

It changes with stock. The Whatnot page shows live prices; UK numbers have been among the cheapest.

What if I lose access later?

The number returns to the supplier after 20 minutes, so keep an email on the account for recovery.
