Import marker boxes from postcodes

For a list of branches or customers, import the postcodes and matching labels together rather than placing each marker by hand. Import up to 500 locations at a time; contact GBMaps if your job needs more.

1. 1

   Postcodes column

   Paste one full postcode per line, without a heading row. Keep the order exactly the same as the labels in the neighbouring box. The count helps you spot a missing row.

2. 2

   Marker text column

   Paste one matching label per line. For example, the first postcode and first label must describe the same branch. Avoid sorting just one column in your spreadsheet.

3. 3

   Import markers

   Looks up the postcode locations and creates the marker collection from the paired columns. Check the resulting markers and any failure message. Use a saved copy before replacing an existing set of annotations.

4. 4

   Advanced import

   Opens the modal importer with extra columns for size, colours, callout, position and London inset handling. Use it when individual rows need different styling or you want a reusable CSV file.

5. 5

   Maximum import size

   Dots and shapes support up to 2,500 locations per import. Marker boxes remain limited to 500 locations per import. On supported Eircode maps, no more than 200 of those locations can be full Eircodes. These are import limits, not a promised total number of objects per map. If you need more, choose Contact GBMaps and tell us the map, the type of import and approximately how many locations or rows you need, so we can discuss options. See Import limits for the other tools.
