When you intend to geocode a list of postcodes, it's entirely possible, though the approach depends on your specific objectives. Here are multiple possibilities:
If you wish to geocode a list of postcodes and navigate through the entire geocoding process, the postcodes are represented as points on the map. Typically, the geographic center of a postcode area is used for this purpose. For more detailed information on geocoding, we refer you to this page with a simple definition of geocoding.
If you possess data at the postcode level and aim to utilize it for a heatmap illustrating postcode areas, you can directly link the data to postcode regions on the map using the Map Postal Codes option. For further insights into these choices, we invite you to explore our documentation on Mapping Postal Codes.
