WhatsApp username checker and rules
WhatsApp has no public username lookup, so our check gives you a link to open in your own WhatsApp. If a chat opens, the name is taken; if WhatsApp can't find it, reserve it. How our checks work
What can a WhatsApp username contain?
English letters, numbers, periods and underscores, 3 to 35 characters, with at least one letter.
| Character | Allowed? | Where |
|---|---|---|
| Letters a to z | Yes | At least one |
| Numbers 0 to 9 | Yes | Anywhere |
| Period (.) | Yes | Not first or last, never two in a row |
| Underscore (_) | Yes | Anywhere |
| Accents, spaces, other symbols | No |
It can't start with www. or end like a web address, such as .com. Capitals don't count, but periods and underscores do, so jo.hn and john are different names.[1, 2]
Can a business get a WhatsApp username yet?
You can reserve one now, and usernames go live country by country later in 2026. Businesses could start reserving on 29 June 2026.
WhatsApp doesn't publish a country list. It tells you in the app when usernames reach your country. On the WhatsApp Business Platform, your business portfolio needs a higher messaging limit before it can claim one.[1, 2, 3]
How do you reserve a WhatsApp username?
Update WhatsApp, then open Settings, Account, Username and enter the name you want.
- Check the name above, with Instagram and Facebook.
- Update WhatsApp, then go to Settings, Account, Username.
- If the same name is yours on Instagram or Facebook, add your WhatsApp account to Accounts Center to claim it.
- On the WhatsApp Business Platform, claim it in WhatsApp Manager or Meta Business Suite instead.[1, 2, 3]
What should you know before reserving a WhatsApp username?
Some names are held back for their owners, and nobody can search for your username.
| Fact | What it means |
|---|---|
| Instagram and Facebook names | Held for whoever owns them there |
| Well-known names | Held for public figures, governments and Meta Verified accounts |
| Blocked words | Such as bank, government, police and verified |
| No search | People need your exact username to reach you |
| Your number still shows | A business's phone number is shown when it messages people |

What can go wrong with a WhatsApp username, and how do you fix it?
Most problems come from the gradual rollout or a name someone already holds.
| Problem | Fix |
|---|---|
| No Username option | Update the app; WhatsApp will tell you when it reaches you |
| The name is taken | Use WhatsApp's username suggestions or a close version (what to do when your handle is taken) |
| Your own Instagram or Facebook name shows as taken | Link WhatsApp in Accounts Center, then claim it |
| A name with accents fails | Use English letters only |
| The Business Platform refuses your claim | Your portfolio needs a higher messaging limit |
Which platforms should you claim with WhatsApp?
Instagram and Facebook first, because their owners get first claim on the same WhatsApp name. Then Telegram and the .com. See every social and messaging platform we check, or read how to grow on WhatsApp.
