What this product checks

Submit a phone number for a Viber account-registration check. The result is an account signal, not a Viber message delivery receipt.

Reading the result

A conclusive yes or no describes the account signal at the time of checking. Unknown means no conclusive answer; it must not be treated as no. A registration signal does not verify identity, consent or message delivery.

Where teams use Viber checks

  • Plan messaging in markets where Viber is a common everyday app.
  • Compare Viber and WhatsApp coverage of the same list before choosing a channel.
  • Remove numbers without a Viber account from a Viber campaign audience.

−70%

1,000 valid unique numbers from one country cost $0.15 at the bulk price ($0.00015 each). A country with only 300 numbers is still checked and is billed as the minimum number of checks: $0.075. Checking the 1,000 numbers one by one at the single-check price would cost $0.50.

This is the cost shown before you submit. Duplicates and invalid rows are removed first; a completed list is charged this amount, unknown results included, and a failed list is refunded in full.

Viber check questions

How much does each Viber check cost?

$0.0005 per single check, in real time. In a bulk task each country is its own group at $0.00015 per check; a country with only a few numbers is billed as the minimum number of checks. A group is charged in full once its batch completes, unknown rows included, and refunded if the batch fails.

Is an unknown Viber result charged?

Not in a single check: only a conclusive answer is charged. In bulk, yes: each country is charged in full once it completes, unknown rows included; a list that fails is refunded. Invalid rows and duplicates cost nothing.

Can I check Viber through the API?

Yes. Send POST /api/v1/checks with the product ID viber for one input, or POST /api/v1/bulk-jobs with a file for a list.

Example request

POST /api/v1/checks
curl "https://api.numdetect.com/api/v1/checks" \
