(^[ABCEGHJKLMNPRSTVXY]\d[ABCEGHJKLMNPRSTVWXYZ]?\d[ABCEGHJKLMNPRSTVWXYZ]\d$)|(^\d{5}(-\d{4})?$) This permits Canadian Postal Codes without the space and American Postal Codes. - If a purchaser enters an invalid postal code (ie: X1X 1X1) which is supposed to be Canada Post's format but doesn't work with the Canada Post plugin, then they receive a custom error message, however they are STILL PERMITTED to continue with the purchase which indicates Free Canada Post shipping. It looks like I need a way to prevent the user from entering the incorrect Postal Code format at the time they are entering it, or somehow convert it to the correct format. - [ ![hikashop-18-05-01a.jpg](/forum/attachment/43544) ](/forum/attachment/43544 "...-18-05-01a.jpg") [ ](/forum/attachment/43544?download=1 "...-18-05-01a.jpg") Last edit: 8 years 6 months ago by [jukeboxjunkey](/forum/user/15117-jukeboxjunkey "View jukeboxjunkey's Profile").
