postal-code

What is the most complete, precise and reliable way to get the coordinates (latitude / longitude) of a given ZIP / Postal Code of a given country? I need to make a lot of requests, so a high API limit rate (maybe even absent) would be useful. GeoNames dumps would be cool, but it seems to have way too many duplicate coordinates ( example ) and it also seems that their database is missing some ZIP / postal codes for specific countries. Are there any other (reliable) alternatives? While I was reading a Meta question , I came across this link: http://query.yahooapis.com/v1/public/yql?q=select%20

Where can I find a list of all UK full postcodes including street name and their precise coordinates? They should be not like AB1, AB23 etc but AB1 2AA, AB23 5ZZ etc. Preferably for free :) Thanks Doogal You can now get postcode data for free from the Ordnance Survey https://www.ordnancesurvey.co.uk/business-and-government/products/code-point-open.html This doesn't come with street names though If you want the data converted to lat/long then you can grab it from my site http://www.doogal.co.uk/UKPostcodes.php You can download the entire GB postcode data complete with Lat and Long values from

I am looking for a way to calculate approximate distance between two UK postcodes (distance in the straight line is good enough) for analysing data. Preferably easily accessible from java, but C#, native C++ etc. are fine as well. First, you need to translate the postcode into useful coordinates. For example, the Easting and Northing values from a Postcode lookup table, like the one from here: http://www.doogal.co.uk/UKPostcodes.php These Easting and Northing are UK Ordnance Survey grid coordinates in metres from the OS map origin. Convert them into Kilometres by dividing by 1000 Then use a

I'm trying to generate a UK postcode from a latitude and longitude search in Google Maps. For example, a search for 57.350237,-1.977539 in Google Maps returns this: http://i.imgur.com/35iB5.png I want to be able to extract that postcode - AB41 8. All I've seen so far are ideas on how to get the lat,lon from the postcode but not the other way around. Any ideas? Thanks, You could take a look at Google's Geocoding API, specifically Reverse Geocoding . Unfortunately in the UK, the Royal Mail are the only ones with such data of that accuracy and completeness. To access it, you have to pay them for

I am trying to use regular expressions to find a UK postcode within a string. I have got the regular expression working inside RegexBuddy, see below: \b[A-Z]{1,2}[0-9][A-Z0-9]? [0-9][ABD-HJLNP-UW-Z]{2}\b I have a bunch of addresses and want to grab the postcode from them, example below: 123 Some Road Name Town, City County PA23 6NH How would I go about this in Python? I am aware of the re module for Python but I am struggling to get it working. Cheers Eef repeating your address 3 times with postcode PA23 6NH, PA2 6NH and PA2Q 6NH as test for you pattern and using the regex from wikipedia

I’ve got a database full of UK Postcodes, now I’d like to be able to store the latitude and longitude of these specific postcodes along with the record with the database. Is there any way that I can obtain this data free without violating any T&C's? I know I could do this using Google maps API for each postcode, but I have way over 20,000 postcodes in this database and to get the lat and lng for each of these postcodes each time is not an option really. Thanks in advance, M Ben Postcode location data is available free now. See this answer: https://stackoverflow.com/a/2625123/587803 https://www
