The site course-tax.com was designed to offer our web site visitors an on-line resource to find all area code and zip code information within the North American Numbering Plan.
course-tax.com uses mostly information published by the North American Numbering Plan Administrator (NANPA). New overlay codes and splits announcements are received from the NANPA via email and published in the area code news section.
By using our site, you can see area codes by state and city, area code list by number, international dialing codes, and search area code by number.
Our newest service is a reverse phone lookup that allows you to search for the name of the owner of over 80 million phone numbers. If we can't find the name of the owner via our white pages listings, we may leave a request to site visitors to share information about the owner of the phone number.
The advantage offered by this website over similar ones is in the simplicity of its design and navigation structure what resulting in an easy to use, but comprehensive area code resource. Our goal is for all visitors to spend as little of their time as possible looking for information on this website.
We want you to use our site as on-line resource to find the information about area codes and phone numbers that you are seeking. You can search and exchange information about the owners of phone numbers. course-tax.com is updated and maintained on a regular basis. Our costs to operate the web site are paid by advertising.
