Viber "Registration Can't Be Completed": Fixes

Viber "registration can't be completed" usually means the code check failed or the number was refused. Check the number, wait, and try a call.

Try these in order

1. Check the country and number, without a leading 0.
2. Update Viber from the app store.
3. Switch between Wi-Fi and mobile data; avoid VPNs.
4. Wait for the timer and choose to receive the code by call.
5. Restart the phone and try once more.

Other reasons

• Too many attempts: wait a day before trying again.
• Number type: some calling-app numbers are refused.
• Number restricted: a number Viber blocked for spam cannot register.
• Old account: the number may still be active on another device.

Registering on a computer

Viber on a computer links to the account on your phone with a QR code. Register on the phone first.

For codes that never arrive, see Viber code not received.

Activating Viber on a new phone

Viber can move your history to a new phone through its backup feature on Google Drive or iCloud. Back up on the old phone first, then register the same number on the new one and restore. Registration problems are often easier to solve while the old phone still works.
