There are 2 main ways (using Qlik functionalities):
1) join the tables and filter the resulting one with a where condition with wildmatch function (it works as a like but with fields on the same table)
2) Extract the address code as a new field in both the tables and then join them on this new field.
for example you could extract the carachters after comma in the first table and before comma in the second
