We need someone to do some work using our database. We have a zip field in our database stacked with zip codes. We need someone to make a list of all zipcodes in the database. There must be no duplicates, so remove any duplicate zipcodes.
English zipcodes have this sort of format
PL20 8HJ or HA7 2BW.
So from there you would take it from PL20 8HJ to PL. Then write how many zipcodes there are that begin with PL etc.
Do this for all postcodes in the database. You will need coding skills as this is not a manual entry job as there are too many entries.
