Free Carrier Lookup

This carrier lookup tool uses Google's public database to check the numbers; no HLR checks are done. Thus, there can be cases where the data is not accurate. We recommend using Messente's Number Lookup API for the most accurate and up-to-date information.

Invalid phone numbers can prove costly to your business, especially if you’re sending out SMS marketing or verification campaigns to those numbers. Messente’s carrier lookup tool is the ideal solution for keeping your customer database clean from phone numbers that are incorrect or simply don’t exist. You get the following benefits:

• Providing validity, carrier, and location information about each phone number.
• Cleaning up your database.
• Making business processes more effective.
• Increasing your messaging ROI.
• Improving the customer experience.

The free tool supports one number at a time. For bulk validation or integration into your systems for automation, use our Number Lookup API, which enables large-scale validation via RESTful endpoints.

You will see whether the number is valid, which carrier it belongs to, and the associated country or location - essential data for routing messages or cleaning your database.

There are several reasons why text messages don’t get delivered. An invalid phone number is one of the main causes. By using our free carrier lookup tool, you can eliminate incorrect or non-existent phone numbers from your database to ensure you only call or send mass messages to valid numbers. This has a direct impact on lowering your SMS messaging costs and saves you time and resources too. We recommend you use the carrier lookup tool each time you add phone numbers to your database and before you launch an SMS campaign.
