Although cell phone numbers are becoming more ubiquitous than home numbers, they can also be more anonymous. The holder of a number can live hundreds or even thousands of miles away from the area code, or the number can be ported to a different service provider. Online services, including some service providers' own websites, can identify a number by original service provider or current service provider. Find out if your friends are in your network using these search options.
