How do you handle postal code searches?
Postal code searches are not the most clear for geocoding APIs. For example, "75008" is a post code for both, Paris France and Šilalė Lithuania.
If most of your locations are limited to one country, you could set your Widget > General > Postcode preference to that country to see if search results are better.
For example, if your postcode preference is set to Australia, when visitors search for "3003" on your locator, internally we will pass "3003, Australia" to the geocoding API, helping it map to the right place. This does not apply to non-numeric searches (for example a search for "San Francisco" will still return the city of California).
