Stay protected from spam calls with Viber's Caller ID.
Caller ID will display a spam-probability indicator when you receive a call from an unknown number.
Viber's Caller ID is only available on Android mobile phones in select countries.
What is Caller ID?
Viber's Caller ID is a safety feature at its core, providing you with a spam-probability indicator for incoming calls from unknown numbers. This spam probability is based on various factors, among which is how many Rakuten Viber users have previously reported the caller as a spammer.
Turn Caller ID ON/OFF
How the spam score is calculated
Phone numbers that were previously reported by other Rakuten Viber users as a source of spam will be displayed to you with a relevant spam probability indicator. You can still choose to answer the call or decline it. In case you have identified a spam call, by tapping the Report button you help the system improve and protect other users from spam calls.
Post call options
After you finish your call, you can choose to perform the following actions:
Call the phone number back (call costs will apply)
If the caller doesn't have Rakuten Viber, you can invite them to download Rakuten Viber
Tap to report a spammer
How can I report a caller as spam/fraud?
You can report a caller as spam or fraud in the post-call screen. To do that, tap the Report button.
If an incoming call is flagged as spam but comes from a legitimate caller - tap Edit in the top right corner and uncheck the Spam checkmark. Adding a caller name during this step will save it locally (for you only).
Why do I have a high spam-probability as a caller?
While any user can block you from calling them, you must be reported by many users to receive a high spammer probability score by Caller ID.
