One of the oldest sites on the web,
continuously online since 1996!

Our main section is a search engine for finding the location and/or rate centers of telephone prefixes. If you have a phone number you can find out where it is located. In addition, there is a section to find the area codes for communities and/or rate centers. Also, a list of prefixes and which area codes have them.

More telephone-related information is being added regularly. Check back often.

See the index below to see all of what we have.
