Unfortunately, Endicia is unable to ship to certain countries via Priority Mail International and Priority Mail Express International. Any errors or error messages that you may encounter are caused when you try to create a Endicia label for these countries.
The first workaround option for this problem is taking your package directly to the post office. If your package is under 13 oz. you can use First Class Mail International. If either of these two options are unavailable then you can use UPS or FedEx to ship the package.
