SMS sent to invalid phone numbers cause unnecessary costs. Validate recipient numbers, especially before the first dispatch.
Validate a single number
Open Lookup, enter the phone number and pick one of the three lookup types:
- HLR (€0.0116) - checks whether the number exists, is reachable and returns carrier information.
- MNP (€0.0058) - checks whether the number was ported to another network.
- CNAM (€0.0087) - returns the registered caller name (US/CA).
Run the lookup. The result shows whether the number is valid and reachable, plus carrier information, country and number formats.
Validate multiple numbers
Bulk validation of contacts is no longer available in the webapp. For larger lists use our Lookup API and feed the results back into your contact database programmatically.
