I'm unable to see any data dumps on your download page for admin3 and admin4 codes?

How do I find this information i.e. the place name that relates to admin3 and admin4 codes?

Do you mean they are self referencing as follows:

Code:
      select  t4.name as town,
         t3.name as county, 
         t2.name as district, 
         t1.name as admin1, 
         t0.name, 
         t0.feature_class, 
         t0.feature_code,
         t0.country_code,
         t0.admin1,
         t0.admin2,
         t0.admin3,
         t0.admin4,
         t0.population
 from geoname t0
 left join geoname t1 on t1.admin1 = t0.admin1 and t1.feature_code = 'ADM1'
 left join geoname t2 on t2.admin2 = t0.admin2 and t2.feature_code = 'ADM2'
 left join geoname t3 on t3.admin3 = t0.admin3 and t3.feature_code = 'ADM3'
 left join geoname t4 on t4.admin4 = t0.admin4 and t4.feature_code = 'ADM4'
 where t0.name = 'London'
 
 
 


It would help if the documentation was updated as it doesn't make this clear?

no. Your query is wrong. The full code hierarchy is needed in the where clause.

Not sure what you mean. Which file are you referring to - GB.zip is the one I'm using? The above query seems to work?

Please can you provide an example of what you mean. My query is for an autocomplete ajax suggestion.
