# Invalid Country Code

The country code is not a valid ISO 3166-1 alpha 3 code.

### Solution {#solution}

The country code you're using might not be in the correct format. Enter a valid, three-letter ISO code representing the country. This must be in ISO 3166-1 alpha-3 form. For example, for the United States, the code would be 'USA'.
