WhatsApp, Telegram and Signal allow one account per number, YouTube verifies two channels a year, and Google publishes no limit. See the full list below.
A phone number costs money, so a limit makes it harder to create thousands of fake accounts. The limit also affects ordinary people: families sharing a phone, or someone with separate work and personal accounts.
| App | Accounts per number | Good to know |
|---|---|---|
| One at a time | Registering the number on a new phone moves the account there | |
| Telegram | One | One app can hold several accounts, each with its own number |
| Signal | One | Registering elsewhere moves the account; Registration Lock protects it |
| Viber | One | Computers and tablets link from the phone |
| One confirmed account | Remove it from the old account to reuse it | |
| Discord | One | Some servers require a verified phone |
| YouTube | Two channels a year | Stated in YouTube Help |
| Kaggle | One | Needed for GPUs and internet in notebooks |
| Google / Gmail | Not published | Often reported as a few accounts; see Gmail limits |
| Apple | Not published | Apple can refuse a number used on too many accounts |
| OpenAI / ChatGPT | A small number | The limit is not always stated |
| Instagram, TikTok, X | Not published | Varies with region and account history |
Apps change these rules without notice, so treat anything "not published" as a guide, not a promise.
Step-by-step fixes are in phone number used too many times.
Some apps allow separate work and personal accounts; others, such as LinkedIn, allow one per person. A different number does not make a forbidden account allowed. Creating accounts to dodge a ban, or to spam, breaks the rules and usually gets every account closed.
The same number on dozens of apps appears in dozens of databases. If one leaks, it can bring spam and targeted scams. Using an authenticator app rather than text codes also protects you against SIM-swap fraud.
Want to test this before paying? Look at our free Indian numbers or free German numbers, though many apps refuse free numbers.
Google does not publish a number. People often report a few accounts before the number is refused.
No. A number can be on one WhatsApp account at a time.
Sometimes after a long time, but apps rarely say when. Removing the number from an old account is more reliable.
Usually, in the security or account settings, as long as you can still sign in.
It depends on the app. Check its rules: some allow it, and others allow one per person.
