Expression
^[1-9][0-9]{3}\s?[a-zA-Z]{2}$
Description
Validates Dutch Postal Codes (ZipCode). There was a previous one listed here, but it's not entirely correct. Namely that dutch postal codes can contain a zero but cannot start with one, so this one is the adjusted version.

Seems "1831 sA" still is valid now... I propose: ^[1-9][\d]{3}\s?(?!([sS][adsADS]))([a-eghj-opr-tv-xzA-EGHJ-OPR-TV-XZ]{2})?$


Title: The term 'Dutch' is wrong!

The term 'Dutch' is wrong! This is a postal code from The Netherlands, not 'Dutch'! 'Dutch' is NOT a country but a language which is spoken in different countries (with different forms of postal codes). As such, please do not use such a regexp if you know you' users speak 'Dutch'. Their postal code might be quite different!

This is too simple: letter combinations SS, SD and SA are not allowed for historic reasons. F, I, O, Q, U and Y are in use nowadays. I posted a correct(er) one

Sam, I was just looking at your modification and have two questions for you: 1. You say that the letters "F, I, O, Q, U and Y" can't be used, but in the regex you still allow the o (O). Typo ? and if so, in the regex or in the earlier statement ? I'd appreciate it if you could give me a link to the official docs for the specification of the postcodes which contains these exceptions. 2. With your regex, the postal code "1234" (without any letters) WILL pass. This shouldn't happen. I've adjusted your sample to take this into account: ^[1-9][\d]{3}\s?(?!(sa|sd|ss|SA|SD|SS))([a-eghj-opr-tv-xzA-EGHJ-OPR-TV-XZ]{2})$ and in case the o from question 1 should be excluded the sample will become: ^[1-9][\d]{3}\s?(?!(sa|sd|ss|SA|SD|SS))([a-eghj-npr-tv-xzA-EGHJ-NPR-TV-XZ]{2})$ Grz, Jrf

Dutch postal codes cannot contain "SA", "SD" and "SS" and those letters : F, I, O, Q, U and Y. You could use this one : ^[1-9][\d]{3}\s?(?!(sa|sd|ss|SA|SD|SS))([a-eghj-opr-tv-xzA-EGHJ-OPR-TV-XZ]{2})?$
