Erlinsbach (AG) has a larger number of addresses (1241) that incorrectly use the municipality name in the addr:city tag, which correctly should just be “Erlinsbach” as this can be easily fixed within an editor I’m proposing to do so if there is no objection.
In Erlinsbach (SO) we have a similar, but different problem of the same magnitude in that the post code and city are missing from addresses that I’m not proposing to address at this point in time with a bulk edit (addr:city should be “Erlinsbach SO” there).
Bit of geoweirdness: the PLZ4 5017 area for Barmelweid is part of both municipalities and straddles the cantonal boundary.
