What Is a Phone Number Lookup?
Phone number lookups provide more details about a phone number. This can include the phone number subscriber's name as well as the carrier, location, and line type of the number. Distinguishing between a landline and a mobile or cellular number can be useful to check if the phone number is a personal or business number.
Number lookups can also determine if the phone number is associated with a virtual number such as VOIPs. These numbers usually represent a higher risk user or transaction, since they are not the user's real phone number. IPQS can also identify spam scores and risk scores associated with phone numbers reported for abuse. More details about the carrier network can be checked using our free carrier lookup tool.
