Canadian Postal Codes

ZIP CODE AUTHENTICATION REQUIRED 

When making a purchase online, the zip code you enter on your credit card must match the zip code associated with your billing address. 

This zip code is usually the same as the zip code for your current mailing address. 
The first two digits identify the issuer's state, while the last three digits identify a specific town or city within that area. 

For Canadians, your Postal Code uses a combination of three letters and three numbers which totals six characters and will not work.  

When asked for a US zip code, use the 3 digits of your postal code plus 00.
