# Dutch district code (CBS wijkcode) (`nl_wijk_code`)

> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

Code of a district (wijk) of a Dutch municipality in the Wijk- en Buurtkaart of Statistics Netherlands (CBS), WK followed by six characters, the 4-digit municipality code (nl_municipality_code) and a 2-character district number, as in WK059901 for Rotterdam Centrum. In 2026 only Amsterdam uses letters in the district number, as in WK0363AA. The codes of the neighbourhoods (buurten) of a district are nl_buurt_code.
