'''Telephone number mapping''' is a system of unifying the international [[telephone]] number system of the [[public switched telephone network]] with the [[Internet]] addressing and identification [[name space]]s. Internationally, telephone numbers are systematically organized by the [[E.164]] standard, while the Internet uses the [[Domain Name System]] (DNS) for linking [[domain name]]s to [[IP address]]es and other resource information. Telephone number mapping systems provide facilities to determine applicable Internet communications servers responsible for servicing a given telephone number using DNS queries.

The most prominent facility for telephone number mapping is the '''[[E.164]] number to URI mapping''' ('''ENUM''') standard. It uses special [[DNS record]] types to translate a telephone number into a [[Uniform Resource Identifier]] (URI) or IP address that can be used in Internet communications.
