In the UK, postcodes are a mixture of number and letters, e.g. (HA2 8HS) so usually LETTER, LETTER, NUMBER, (NUMBER), NUMBER, LETTER, LETTER.
I have tried to create a geo zone for all postcodes between HA2 - HA7 (including all values within that, e.g. HA3 4AB) but I can't get the Geo Zone which my shipping uses to work properly. It either lets all other codes through, or doesnt work at all.
Does anyone else have any experience in using the Geo Zones with UK postcodes?
Sorry, I haven't tried it with EShop; but if it's any help, in the past I used to have to define UK postcodes as 111111 to zzzzzz (i.e. anything in between) - the space can also cause an issue, but I don't think EShop has a way of automatically adding or deleting it
