I have tried with above three expressions. The regular expression doesn't need a lot of explanation. ^\d{5} says that the regular expression must start ("^") with exactly five ("{5}") digits ("\d"). ([\-]\d{4})? Last expression i.e.Matches US or Canadian zip codes in above formats is not validating if I enter 12345 e123 or 12345 123r. JavaScript regular expression to validate zip code. Let me first show you the JS code.

Some of the addresses are missing a space between the streetname and the ZIP code. I put the code and one of the user complained that it wont work, The user's canada Zip code is M5R 1GR that means the pattern is changed. Now in this Zip code its ANA NAA.

For this we are going to make program named Matching_Zipcode.java. The steps involved in program Matching_Zipcode.java are described below:-

To Check Indian Zip codes use

String zipCode = "\\d{5}(-\\d{4})?":-This is the regular expression use to match with Zip code.

Imports System.Text.RegularExpressions

Function IsValidZip(ByVal sZipCode As String)

Return Regex.IsMatch(sZipCode, "^\d{6}$")

End Function

A valid zip code can either have 5 digits or 5 digits followed by an hyphen(-) and ends with four digits.
