I am using ArcGIS Pro and am trying to select a number of polygons based on a list of postcodes from a standalone table.

I am using the Code-Point Polygon Dataset for the entirety of England, and I am trying to divide this into the 9 regions of England (e.g. East of England, North West, North East etc.) by using the postcodes.io dataset (https://postcodes.io/docs). I have a table listing the postcodes that are in each region, but I can't figure a way to select the polygons from the Code-Point dataset based on whether the postcode is contained within a given region.

Essentially, I have a standalone table listing the postcodes that fall within the East of England, and I want to select the polygons that have a postcode attribute that is matched within that table.

Try to join the table to your feature class, using either Add Join (temporary), or Join Field (permanent), and then Select by Attribute on the region field.

  • Thank you - I hadn't considered this! Now having trouble with ArcGIS Pro endless batch joining fields where null values exist...
