Entering a phone number in a reverse phone lookup service may provide an address for that number. Some lookup services such as 411.com also provide resident names and phone service used.
Many websites have free reverse phone lookup capability, including Anywho.com, Reversephonelookup.com, Whitepages.com and Spydialer.com. Whitepages.com provides a name, address, map and approximate age for the phone number’s owner, while Anywho.com can also find addresses for international phone numbers.
People often do a reverse phone lookup when they don’t recognize a phone number on their mobile phone or landline. This type of lookup can help a consumer screen for telemarketers, creditors and other calls they do not wish to answer. A consumer could also use this technology if he wrote a phone number down but didn’t include and now can’t remember the corresponding address or contact.
