证件号码正则表达式

Question

I'm trying to find a regular expression for bolivian document numbers:

1234567 LP or 1234567LP

I tried using \\w?\\s?, but it accepts special characters, like * or %. There isn't a defined number of digits (6 to 8 digits) or letters (2 to 3 letters). It can has one or none white space character.

Any suggestion? Regards.

Answer 1

try this:

\b[0-9]{6,8} ?[A-Z]{2,3}\b

(if you want to check a whole string, you must add anchors ( ^ and $ ) at the begining and at the end of the pattern. Then word boundaries are no more useful). Example:

^[0-9]{6,8} ?[A-Z]{2,3}$

Answer 2

Regex.IsMatch(input, @"^\d{6,8} ?[A-Za-z]{2,3}$");
