NIS code
From Wikipedia, the free encyclopedia
The NIS code (Dutch: NIS-code, French: code INS) is a numeric code for regional areas of Belgium.
This code is used for statistical data treatment in Belgium. This code was developed mid-1960s by the Statistics Belgium. It was first used for the census of 1970.
The NIS code consists of 5 digits:
- The first number identifies the province. if this digit is followed by 4 zeroes, this code identifies the complete province. Example: 70000 identifies the province Limburg.
- The second digit identifies the arrondissement within this province. If after the two first digits there are three zeroes, then this code identifies the complete arrondissement. Example: 71000 identifies the arrondissement of Hasselt.
- The last three digits uniquely identify the municipality within that arrondissement. Example: 71066 identifies Zonhoven.
Special cases
- The country Belgium received the code 01000.
- The three regions received the codes 02000 for Flanders, 03000 for Wallonia and 04000 for the Brussels region.
- In 1995 the province of Brabant with first digit 2 was split in Flemish Brabant and Walloon Brabant. Flemish Brabant received code 20001 and Walloon Brabant received code 20002. The arrondissements kept their old codes.
- The provinces and municipalities of Brussels are sorted alphabetically on their French name.
