Check the code, not just the pin
Maps shows where a place is. PostcodeDog shows the place, region and national format, and flags when a code is shared by several places or countries.

PostcodeDog vs Google Maps
A postal-code answer, not a map pin.
Google Maps is where people go to see where something is. PostcodeDog is where they go to check whether a postcode matches the city, region and format in front of them.
