Lookup Free service

Our free-to-use Lookup service provides basic number insights to help you keep your contact numbers organized. Validate numbers and formats, eliminate fraudulent contacts, and reduce your undeliverable messages by ridding your recipient lists of inactive numbers.

Number format

Verify that your numbers are formatted correctly and adjust entry errors to ensure your messages get delivered. Filter out numbers that are too long, to short, or contain unsupported characters. Our service applies known standards such as national formats and E.164 to keep your contact lists compliant and up to date.
