How many WhatsApp accounts can one phone number have?
Quick answer
One phone number can have one WhatsApp account and, separately, one WhatsApp Business account, but not both active on the same number at the same time in most cases. Registering the number in one app moves it away from the other. One account can run on a phone plus up to four linked devices. If you want two separate accounts, you need two numbers.
People ask this when they want a second account without a second SIM, or when they're setting up WhatsApp Business. The rule is simple once you separate accounts from devices.
One number, one account
WhatsApp identifies accounts by phone number. If you register a number that already has an account, the account moves to the new device and the old device is logged out.
WhatsApp and WhatsApp Business
WhatsApp and WhatsApp Business are separate apps. A number registered on WhatsApp Business isn't registered on regular WhatsApp. If you move a number from WhatsApp to Business, WhatsApp offers to bring your chats along.
Accounts vs devices
| What | Limit |
|---|---|
| Accounts per number | 1 |
| Linked devices per account | Up to 4, plus the main phone |
| Accounts on one phone | Depends on the phone and app; each needs its own number |
Getting a second number
For a second account you'll keep, use a second SIM or eSIM. To try a second account, a Noir SMS number can receive the registration code, keeping in mind it's single use.
Frequently asked questions
Can I have two WhatsApp accounts on one number?
No. One account per number.
Can I use the same number on WhatsApp and WhatsApp Business?
Not at the same time in most cases. The number moves to whichever app you register last.
Can my whole team use one WhatsApp account?
Up to four linked devices can share one account. Larger teams use WhatsApp's business platform.
Is it allowed to have many WhatsApp accounts?
WhatsApp's terms are about how you use it. Mass-creating accounts for spam is banned, and Noir SMS doesn't allow it.
