An extremely simple, lightweight way of requesting the Geolocation (lat, long, easting, northing) for any UK Postcode, as well as district and ward details.

Get information on a UK postcode


  • Ruby

  • Rubygems

Install the gem

sudo gem sources -a
sudo gem install pat

Include the gem in your project

require 'pat'

Request a postcode

@postcode = Pat.get("N1 1AA")

Use the results (returned as a hash)

puts @postcode["geo"]["lat"]
puts @postcode["geo"]["lng"]
puts @postcode["geo"]["easting"]
puts @postcode["geo"]["northing"]
puts @postcode["geo"]["geohash"]
puts @postcode["administrative"]
puts @postcode["administrative"]["district"]
puts @postcode["administrative"]["district"]["title"]
puts @postcode["administrative"]["district"]["uri"]
puts @postcode["administrative"]["ward"]
puts @postcode["administrative"]["ward"]["title"]
puts @postcode["administrative"]["ward"]["uri"]
puts @postcode["postcode"]

Try it out

irb -r rubygems -r pat

p = Pat.get("<your postcode here>")

Note on Patches/Pull Requests

  • Fork the project.

  • Make your feature addition or bug fix.

  • Add tests for it. This is important so I don't break it in a future version unintentionally.

  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)

  • Send me a pull request. Bonus points for topic branches.
