Geographic number
type of telephone number
A geographic number is a telephone number, from a range of numbers in the United Kingdom National Telephone Numbering Plan, where part of its digit structure contains geographic significance used for routing calls to the physical location of the network termination point of the subscriber to whom the telephone number has been assigned, or where the network termination point does not relate to the geographic area code but where the tariffing remains consistent with that geographic area code.
In the Netherlands any telephone number consists of 10 digits and the geographic number is often separated with a minus sign. The number 0592 for example is the geographic number for the area in and around the city Assen, and Groningen uses 050. Someone living in Assen has a caller ID of 6 numbers and someone in Groningen has a caller ID of 7 numbers.

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
