Numbering codes for service providers

A numbering plan is a type of system used in telecommunications for  assigning numbers to every terminal or device on the network, so that  each can be reached through direct dial numbers. In Dominica, a National  Numbering Plan is used for allocating numbers among telecommunications  providers and is managed by the Commission in accordance with the  regional numbering plan established by ECTEL.
