Change the street address format
If you have contacts from different countries, you can change the format of their addresses to match their locations, to help correctly map the addresses. You can also change the default address format that Contacts uses.
Change the address format for a contact: Select a contact, then click Edit. Click an address label (such as Home), choose Change Address Format, then select the country or region that matches the address.
Change the default address format: Choose Contacts > Preferences, click General, click the Address Format pop-up menu, then choose a country or region.
