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.

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

Hey guys, thanks for the KML! I wrote a script to convert the data to SVG format and thought it might come in handy for others:

What's the difference between coordinates and coordinates8?
By Richard on 18th March 2013

So i've been using this data to render an svg out, so far so good, except the map is 90degrees clockwise :D However, Good stuff man :)
