There are so many variants, house numbers should just be a free text field allowing any combination of alphanumeric characters. Even more important, Waze needs to also allow searching of the same.

Australian addresses strangely work opposite. If the address was 3/12 then 3 is the unit number and 12 is for the building number. This type of address are seen in townhouses, unit complexes, and gated living

Australia also has addresses with letters in them usually for a detached house with multiple residences or a parcel of land divided with seperate houses. An example of these addresses would be 12a and 12b, rarely do you see a c

Hey, this would really be handy. Waze editor support the "1/14" house numbers, but address search does not navigate to them. We often have "4/a" house number in Hungary, too.

Agreed with this suggestion. We also have 1/2 addresses in parts of Pennsylvania too.

2763/1

Lukas - If you are from CZ/SK - that is different - those are not subdivisions of single house number, those are different numbering schemes - i.e. each number identifies the single house independently.

AND needs to be searchable as well !

Yes number 2583/25 or 84a its very usefull

I am also in order to add "/" A lot of home in my city has, for example, 256/26.

Well I live at 105/A, but dunno, it might be usefull, but for example we are 3 houses 105, 105/A, 105/B and we are right next to each other.

Or there can be letter before number, for example E820 - this sign is mostly for cottages...

In our country many houses and buildings have number with or with not / and not only with number but also with alphabet example: 12/A, 12/B etc ...

Another use for the slash would be for fractional addresses. There are HNs in Boston, e.g., that are "1/2" (literally, one-half, a house tucked in at the beginning of a street).
