Hi Ed,

WOW! Thanks. I wasn't even going to try to format for the Canadian zips yet. My old mask was '99999-9999' and that didn't allow for the alpha in the Canadian zips, so they couldn't enter them. I didn't know the actual format of the Canadian zip anyway - 'til now thanks to you. This does muddy the waters slightly though: not all US zips will have 9 digits, some will be just 5. Hence I can't arbitrarily use the !9!9!9 mask if less then 9 digits. Maybe IF LEN(RTRIM(zip_code)) = 5 OR LEN(RTRIM(zip_code)) = 9 US Format ELSE Canadian format.

Thanks again. Have a nice day. Don't let the Love Bug Bite.

Regards,

Paige
