How Does Phone Lookup Work?

There are six common methods of phone lookup based on public online services and sources.

The most apparent method unsurprisingly results to be a proven one. White pages services and call providers databases were go-to places for phone lookup from the beginning of the 2000s, and they still get millions of daily traffic. This is definitely the destination where you should start the search.

  • WhitePages — the oldest mobile phone database with 85% of American numbers as well as 5 million+ international numbers. The free version allows checking the owner’s age, name, address. The holders of paid subscriptions get access to a detailed profile. 

  • — AT&T-founded service, the website collects private and business numbers of all service users. The site also has a business version — Yellow Pages — for tracking corporate contacts and getting business data on the number’s owner.  Here, you can get the user’s address, map, name on a free plan. The website receives approximately 3.3 million users per month, which makes it one of the most popular contact platform.

  • Google works better with business phones than with personal ones. These days almost each business has a website with contact data — phone, mobile number, email.
