Please enter your Postal Code with a space between the first three characters and the last three characters, for example A2A 2A2.
Please note for Canadian Postal Codes the second character is always a 'number' not a 'letter', and in the second set of three characters, the first character is a 'number'. For example A3A 4G8, and the last character is also a number. (Lower case characters will be transformed to upper case characters for you.) If you enter the characters incorrectly the box outline will trun red and if you click the search button you will get an error message.
If the input box has a red outline around it, that means your Postal Code is either missing a space after the third character, or you have typed a letter where a number should be, or a number where a letter should be. Just fix it and the red outline should go away once the format is correct. The click on 'search'.
