About Countries/counties/postcodes (CS20400S)

You use this window to store information about countries and counties where your organisation has operations, customers, or suppliers. The information you provide here is used to define branches of your company and to create customer and supplier accounts.

You identify countries by a two-letter country code in accordance with the ISO 3166 standard. Country information includes the phone code for the country, input masks for postcodes and VAT registration IDs (if required), and information about country administrative units (counties or provinces).

You can also track whether VAT registration is required in the country. If you set up input masks and regular expressions for postcodes, users can avoid occasional input errors.

This window is also where you set the customer validation settings for AutoInvoice on the Customer validation tab.
