HAS gray pages directory is a phone book that differs from a standard phone book in that entries are listed by phone number instead of name. A gray page directory is also known as a reverse phone lookup directory, reverse phone directory, reverse lookup directory, reverse phone listing, reverse phone directory, cross directory, and other similar close derivatives.

While you can easily find a free gray pages directory that contains landline numbers, you won’t have as much luck with cell phone numbers. This is because information related to cell phone owners cannot be found in the public domain, but is scattered throughout the databases of many cell phone companies.

Savvy entrepreneurs spotted the demand for gray page directories (re: cell phone numbers) and consequently various reverse phone lookup Companies have sprung up in the US over the last decade or two. These companies have collected information about the owners of mobile phone numbers from various sources and offer online lookup services, for a price of course. Many of these companies offer a basic search function to identify the name and address of the owner of a cell phone (or landline number, even those not listed) and supplement this service by offering additional information, such as criminal background check, background check, details about neighbors, relative etc. You get what you pay for as always.

You may find some companies that offer free reverse cell phone lookup features, but you will find that such free features end with no information other than the name of the phone company and provider. You will then be invited to pay for any useful information.

Of course, gray page directories are used by the police, other law enforcement agencies, and emergency services, but their directories are off limits to the public.
