WhatsApp Web and virtual numbers: what works and what doesn't
Quick answer
WhatsApp Web is a companion: you can't register a number on it directly. First register the number in the WhatsApp app on a phone, which is where a virtual number receives the SMS code, then link WhatsApp Web by scanning the QR code. After that, Web works normally. The account still depends on the number, so add a two-step PIN and email, and move it to your own number if you'll keep it.
Many people want WhatsApp only on a computer, for work or because they don't want it on their phone. WhatsApp Web and the desktop app make that possible, but only after the account exists on a phone. Here's how the pieces fit when the number is a temporary one.
WhatsApp Web can't register numbers
WhatsApp Web, the desktop app and WhatsApp on a second phone are linked devices. They connect to an account that was registered in the WhatsApp app on a phone. There's no option to type a number and receive a code on the web.
How to set it up with a virtual number
- Register WhatsApp in the app on a phone or tablet with the number, receiving the SMS code in your Noir SMS dashboard.
- Open web.whatsapp.com or the desktop app and scan the QR code from the phone in Settings, Linked devices.
- Set a two-step verification PIN and add an email in the app.
Does the phone need to stay on?
Linked devices work without the phone being online all the time. WhatsApp may log out linked devices if the main phone stays inactive for a long period, so open the app on the phone occasionally.
Keeping the account
If WhatsApp ever asks you to re-register the number, for example on a new phone, it sends a new code to that number. A recycled temporary number won't receive it. For an account you'll use long term, use WhatsApp's Change number to move it to a number you control.
Frequently asked questions
Can I verify WhatsApp on a PC?
Not directly. Register on a phone first, then link the PC with the QR code.
Can I use an Android emulator instead of a phone?
Some people do, but WhatsApp may flag unusual setups. A real phone or tablet is more reliable.
Will WhatsApp Web log out if the number expires?
The Noir SMS reservation ending doesn't log you out. Problems only start if WhatsApp asks you to verify the number again.
Can I use WhatsApp Business on the web?
Yes. WhatsApp Business also supports linked devices, including the web.
