Saint Kitts and Nevis HAS NO ZIP CODES OR POSTAL CODES. It is used in some Countries like Canada, South Africa, USA etc. but not in Saint Kitts and Nevis. That shouldn’t stop you from using a postal code, Most people have resorted to using 00000 or 12345. These are numbers they generated by themselves. I know that some of you will be asking what to use when filling a form online or when shopping online. you just have to use any code you like but i will suggest using 00000 Mind you 00000 is not the real postal code but since you really need to input your zip or postal code in a form you just have to use anything.
