Regular expression for Dutch phone number

问题

I'm looking for a regular expression to match a Dutch phone number. These are the formatting requirements:

Should start with 0
Contains maximum of 1 (optional) dash "-" character, for now it does not matter where it is, as long as it's not the first character
Total length 10 or 11 characters

This is what I've come up with so far:

^0+-{1}?([0-9]{10,11})$

I have seen this before at http://regexlib.com/Search.aspx?k=phone%20number Check this website out, hope it helps.

(^\+[0-9]{2}|^\+[0-9]{2}\(0\)|^\(\+[0-9]{2}\)\(0\)|^00[0-9]{2}|^0)([0-9]{9}$|[0-9\-\s]{10}$)

Regular expression to evaluate dutch-style phone numbers. Possible example prefixes: +31, +31(0), (+31)(0), 0, 0031 followed by 9 numbers (which can contain a space or -).

Try this regex: ^(?=^.{10,11}$)0\d*-?\d*$

I came up with this creation

^(?:0|(?:\+|00) ?31 ?)(?:(?:[1-9] ?(?:[0-9] ?){8})|(?:6 ?-? ?[1-9] ?(?:[0-9] ?){7})|(?:[1,2,3,4,5,7,8,9]\d ?-? ?[1-9] ?(?:[0-9] ?){6})|(?:[1,2,3,4,5,7,8,9]\d{2} ?-? ?[1-9] ?(?:[0-9] ?){5}))$

Here is a regex for Dutch mobile phonenumbers including a check for international prefixes (0031 or +31). Check it at: https://regex101.com/r/Y2DG19/1

^\(?([+]31|0031|0)-?6(\s?|-)([0-9]\s{0,3}){8}$

Hope this helps people out.

here's my solution:

extension String {
    func isValidPhone() -> Bool {
        let dutchRegex = "^(06[0-9]{8}|[+]{1}31[0]?[0-9]{9,10}|0031[0]?[0-9]{9,10})"
        let phonePredicate = NSPredicate(format:"SELF MATCHES %@", dutchRegex)
        return phonePredicate(with: self) 
    }
}

This will validate all numbers with +31, 06, 0031 so will only work for Dutch phone numbers

回答6:

You can also do it like this. First you remove all not digits and then you check the number with the regex.

const regex = /^((\+|00)?31|0(?!0))(\d{9})$/;
const valid = regex.test(input.replace(/\D/g, ''));

It works with numbers starting with 0031, +31, 0.

I tried to elaborate on @Raj's solution by adding some more constraints on the use of hyphens or spaces, because it somehow captured 06-01-2019 as well. I placed some comments in there as well to provide examples:

\b(\+[0-9]{2}(?# e.g. +31)|^\+[0-9]{2}\(0\)|\(\+[0-9]{2}\)\(0\)(?# e.g. +31(0)|00[0-9]{2}(?# e.g. 0031)|0)([6][\-\s]?[1-9][0-9]{7}(?# e.g. 0612345678 or 06-12345678 or 06 12345678)|[6][\-\s]?[1-9][0-9]\s?[0-9]{2}\s?[0-9]{2}\s?[0-9]{2}(?# e.g. 06-12 34 56 78)|[6][\-\s]?[1-9][0-9]\s?[0-9]{3}\s?[0-9]{3}(?# e.g. 06-12 345 678)|[6][\-\s]?[1-9][0-9]{2}\s?[0-9]{3}\s?[0-9]{2}(?# e.g. 06-123 456 78)|[0-9]{2}[\-\s]?[1-9][0-9]{6}(?# e.g. 030-1234567)|[0-9]{2}[\-\s]?[1-9][0-9]{2}\s?[0-9]{2}\s?[0-9]{2}(?# e.g. 030-123 45 67)|[0-9]{2}[\-\s]?[1-9][0-9]\s?[0-9]{2}\s?[0-9]{3}(?# e.g. 030-12 34 567))\b

(I know... And I didn't even cover all cases containing whitespaces)

回答8:

I have generated the following one for Dutch mobile numbers. Until now, I tested with some possibilities and was able to cover them. I hope it helps.

\(?(31\s*|0)-?6(\s*\)?|-?\s*)([0-9]\s{0,3}){8}
