I have recently discovered Cartodb and I am trying to create a bubble/thematic map of postcodes. I have a csv document with one column of postcodes from around the UK. I have uploaded the dataset and when georeferencing the data i choose from the postal code tab and enter United Kingdom as a country.
The issue is that only a handful of the post codes got georeferenced while the rest remain null. The postcodes are valid so not sure why it's not working.
Is there something I am doing wrong?
EDIT here is an screenshot of the data, you can see a few have their long/lats while others don't
