In addition to identifying the name of the carrier, you can check whether a number is mobile/cellular, landline, or VOIP. This information can be extremely valuable for determining the best communication channel for your customers or prospects.

Depending on the service, it can also confirm if a number is active or disconnected, provide the owner’s name and business name, and perform spam & risk scoring. The free home location registry (HLR) API used by IPQS can connect directly to a telecom’s network and retrieve the underlying details of a phone number, providing more insight into its quality.

A common use case for a phone number lookup is to verify that a number belongs to an eligible wireless carrier before sending text messages. Some states have laws that require carriers to include their carrier ID in the message they send to users, so this is an important step for compliance.

Invalid phone numbers can be expensive to deliver to – and they waste valuable time on a team. This is especially true of mobile messaging, where each message can contain images and GIFs that are not supported on all devices. The easiest way to prevent this from happening is by regularly cleaning your contact list with our free carrier lookup tool.
