Iowa

Iowa is reportedly one of the safest states to live in the United States. The Hawkeye state joined the union in 1846 and has since become an economic hub for agricultural, manufacturing, and financial businesses. Over three (3) million people live and work in Iowa. Information on residents and businesses with registered phone numbers is available on the Iowa phone number database. 

Generally, an Iowa phone number begins with one of five area codes. Telephone companies began using area codes in 1947 as a better way to facilitate long-distance phone calls.

Before then, phone companies used switchboards. However, this system could not handle the volume of phone calls that came with the broader availability of telephones after world war II.

Another relic of the past is phonebook directories, aka white pages. These directories listed the name, address, and phone numbers of persons living in a small town or city block. However, just like switchboards, phonebook directories became inefficient when more people began to own phone numbers. Phone companies couldn’t just keep up with the cost of printing several editions of white pages every other month. Besides, white pages were often the targets of vandalism—people tore off pages for personal use or privacy reasons. 

Iowa white pages are now available online and better. You can now access names and contact addresses by performing a reverse phone lookup on the Iowa phone numbers database. How does this work? When a resident purchases a phone number, their mobile carriers typically require them to register personal information and contact details. This registration and the uniqueness of a phone number make it possible to obtain information about a phone number owner with a reverse phone lookup. 

Consider the typical Iowa phone number, 515-NXX-XXXX. The first three digits of the phone number, 515, is the area code for a defined city. The next three digits, NXX, the prefix code, specify the specific town or street where the phone number owner resides. Finally, the line number, XXXX, is unique to the specific owner. So, if the phone number were to be a house address, the line number would be a specific flat number or house number. 

Many persons can have the same area code and prefix code. However, the line number is unique to a specific individual. No two persons have the same line number. Thus, when you perform a reverse phone search, you only get the information logged for the registered owner of that phone number.
