Welcome to e164.org

What is e164?

In a nutshell: E164.org is a public enum directory of telephone numbers that can be reached over the Internet by anyone anywhere!

The system works by publishing a DNS zone, 'e164.org', that can be used by various Internet applications. The idea is to be able to map your phone number to an Email address, website, VoIP addresses, etc. Find out more.

We also have a Frequently Asked Questions page.

If you control large blocks of numbers, or would like us to handle your e164.arpa delegation, please contact us to discuss your requirements and options.

We have a number of plugins to integrate enum lookups into other applications
