FAQ
Carrier Detection questions
Can I look up carrier information in bulk? +
Yes. Call the REST API with a phone number and country code, and the response returns validity, line type, carrier, and region for that number. You are billed only for successful lookups.
Does the check message or notify the person? +
No. The check is passive and only queries carrier and line-type data. Nothing is sent to the number, and the account holder is never contacted or notified.
Which countries are supported? +
Carrier Detection supports multiple countries; you pass a country code alongside each number to get accurate results for that market.
Is there a free trial? +
Yes. New accounts receive free checks on signup, and every check is pay-as-you-go with no monthly fee.
