Checkout your postal code on

http://jsfiddle.net/hgU3u/

^ matches beginning of string
[1-9][0-9]{3} matches a single non-zero digit, and three 0-9 digits
? matches 0 or 1 spaces (you could use * to match 0 or more spaces)
(?!sa|sd|ss) is a lookahead test to check that the remainder is not "sa", "sd", or "ss".
[a-z]{2} matches 2 a-z characters
$ matches the end of the string
/i at the end (from sabof's answer below) to simplify this (otherwise you would need to test !sa, !SA, etc... would be unnecessarily lengthy)

Thanks for your time. The above Regex match 1011 SD but it didnot match 1011. Please help. I need a Regex which matches both the value 1011 and 1011 SD.

Maybe this:

C#

"^[1-9][0-9]{3}\s*(?:[a-zA-Z]{2})?$"
