[Tagging] New tag for major recipient postcodes

[Rainer]

Hi all,

recently I came across postal codes in POI addresses, which aren't the 
classic scheme addr:postcode & addr:city & addr:street & 
addr:housenumber. However it is a special postcode that is assigned to 
recipients that receive a big amount of post every day, typically big 
companies or authorities. This kind of postcode is used only together 
with addr:city and does not require street and housenumber. So to say 
the post company has a big sack for post to that special postcode, puts 
in all the letters that are addressed to it and delivers the sack to the 
recipient.
After some discussion in the german user forum 
https://forum.openstreetmap.org/viewtopic.php?id=60421 I want to propose 
a tag for this kind of postcode and would like to discuss it here in the 
tagging mailing list.

The proposal is:  addr:postcode_major_recipient

It should be used on POIs, because it is an attribute of the company, 
authority or whatever, but not as an address of a building, because it 
is not assigned to such directly. Target is to have a separate tag for 
this kind of postcode to avoid a mix-up with the normal addr:postcode.

As I am not a native British English speaker, I have asked one and 
consulted the english page of the Deutsche Post. Reference: 
https://www.postdirekt.de/plzserver/PlzSearchServlet?lang=en_GB -> goto 
More -> Find major recipient

Probably similar kinds of postcodes exist also in other post companies 
in other countries, so inputs about that are welcome.


Best regards,
Rainer
