Area codes
of the Netherlands

A Dutch number is ten digits with its trunk 0, and the area code is the first three or four: 020 is Amsterdam, 010 Rotterdam, 070 The Hague, 0111 Zierikzee. There are 141 of them, and each one on this map is drawn as the places it serves — every woonplaats the regulator's net includes, on the Kadaster's own boundaries. The colour is the first digit after the 0, the five regions the plan was laid out in, with the 07x codes, given to cities all over the country, as a class of their own.

How to read the map. Each patch is a code and the numeral on it is what you dial there; the place beneath it is what the regulator calls the net. The colour is the first digit after the 0: 01 is the south-west, from Zeeland through Rotterdam to Breda; 02 the north-west, Noord-Holland; 03 the centre, from Utrecht to Arnhem and the new land of Flevoland; 04 the south-east, eastern Brabant and Limburg; 05 the north and east, from Friesland and Groningen down through Overijssel to the Achterhoek. The 07x codes — 070 The Hague, 071 Leiden, 076 Breda, 077 Venlo — were added for cities wherever they were, and have no region, so they are coloured apart. The big cities have two digits of their own, 010 to 079, and a few smaller ones do too: 013 Tilburg, 015 Delft, 046 Sittard.

Where the lines come from. The ACM administers the codes and names each net after its principal place, but publishes no boundaries. The Dutch Wikipedia list names every place in every net, and the Kadaster's BAG — the national register of addresses and buildings — has a boundary for each of the country's 2,503 woonplaatsen. So each code is the union of the places its net names. A place name that belongs to two or three woonplaatsen, which happens 132 times, goes to the one nearest the rest of its net; 220 places no net names — the Frisian villages the list spells in Dutch, hamlets, the harbour land of Rotterdam — take the code of the nearest place that is named, which is right except possibly on a net's border. Everything is drawn; nothing is left white.
