To find out whose number a phone belongs to, you can use a reverse phone number lookup service. These services allow you to enter the phone number and retrieve information about the owner, such as their full name, location, carrier, and sometimes additional details like social media profiles or address history. Here are some popular free and reliable options:

• IPQualityScore (IPQS) : Provides detailed info including carrier, line type, location, spam and risk scores, and can identify if the number is mobile, landline, or VOIP
