Thanks for this. Can you produce the same but for outward code?

Thanks. We have renamed and moved any reference to Outcode to Area.

This isn't by UK Postcode Outcode, it's by postcode area

Not quite what I was expecting. A bit disappointing.

Sharon, sorry, not sure about where to find this data.

Hi, I see from other comments that this data isn't as detailed as would be useful, i.e. Post Code District or sector level, do you know if this would be available in KML format anywhere?
By Sharon Brittain on 29th August 2018

These are NOT outcodes. Outcode is the whole first part of the postcode e.g. NE28, not just NE!

Hi there We are also looking for KML files showing the postcode breakdown areas within each outward code Eg DE1, DE2, DE3, DE4 We have developed a tool in house to return a list of postcode breakdowns within a certain radius of a given postcode .. Eg All postcode breakdowns within 20 miles of DE1. However, we want to be able to visually see the postcode breakdowns on this map Do you have this KML data for us to download and utilise? Thanks Rob

Each Outcode is the name for each placemark in the KML file.

This is useless without the names of the postcodes.

The KML download is fantastic but was hoping it would be possible to also include postcode districts, even if just for London (or where one could find this), e.g. "W1-14" instead of just "W" which is in itself not that helpful. Thank you very much indeed!

Hi Andrew, have a look at KML Layers.
By Free Map Tools on 25th June 2014

Does anyone know if there is a way to use this with Google Maps API V3? Thanks
By Andrew on 6th June 2014

These are postcode areas, which make up part of the outcode. They are are not postcode districts - those are not free

Hi Guys, I need to get much more detailed than the outcode boundaries. Do you have a file that gives details of full outbound codes such as RG24 rather than just RG? I need to find polygons to overlay onto Google maps, any ideas? Thanks
