Rules for address details
- The Street names must be valid.
- House numbers or building numbers are mandatory. They can either be included in the Street field, or they can be used in the field especially assigned for them.
- The zip code must be valid and recognized by our routing database. If the zipcode/country/service code combination doesn't yield any result from our routing database, it's not permitted to use that combination. Please refer to http://www.geopostcodes.com/data to look up correct postcodes and refer to https://en.wikipedia.org/wiki/ISO_3166-1#Current_codes for the correct Alpha 2 ISO and Numeric country codes.
