There are three types of ENUM, the '''Public User ENUM''', which allows an end user to enter his or her own records in the ENUM registry under the public dumaine164.arpa ehereby the DNS is publicly available to any internet user; '''Private Infrastructure ENUM''' is used  by a closed group without using the e164.arpa public domain instead, they opt to use the process of creating a domain name from a telephone number and resolving it to a URI to exchange IP traffic; and the third type is the '''Public Infrastructure ENUM''' which is assigned by a National Number Administrator which normally delegates a telephone number to a carrier, which in turn assigns the telephone number to an end-user. The Carriers maps telephone numbers to an internal network addresses to enable call routing features which are not publicly available, highly secure and the access is restricted only to other service providers.<ref>[http://www.enum.org/what/types Types of ENUM]</ref>

# It serves as single number point of contact wherein  a single ENUM number facilitates the routing of telephone calls to the internet instead of the regular telephone sytem, meaning it allows numerous access to different types of communication such as fax, cellular phones and many others.
