Find any 730- phone number in Illinois
The 730 area code is an Illinois-based code created in 2008 as part of a relief plan that was necessary due to the increasing numbers of phone lines in the state. Serving as the first-ever overlay code for the Illinois territory, the area code made room for thousands of additional phone numbers within the state by combining the existing 630 and 847 area codes. This was important for the state, as their population is considerable and their needs for phone lines were much larger than what these two area codes could have handled alone.
Area codes are each part of the North American Numbering Plan (NANP) which assigns specific areas of a particular region to a specific 3-digit combinations known as the area code. These area codes are then further broken down in to 7-digit numerical combinations known as central-office codes. This area-specific system is widely used in North America and allows for easy transmission of calls and messages to multiple destinations within a single region. In the case of the 730 area code, all phone numbers in Illinois that include this code, can be accessed through the NANP framework.
