Hi, which countries have bigger part of streets (especially in small villages) unnamed? Is it low street name site only in Czechia and Slovakia or is sparse street-named site in some other countries? And which countries have full street-named site, are streetnaming mandatory there?
In Poland entire villages may have unnamed streets. The addresses are simply Village 12, Village 13 etc. We use addr:place for that instead of addr:street. A couple of examples:
The rule of thumb is: the simpler the road network, and the smaller the village is, the more probable it is there will be no street names (although there are many regional variations).
Japan uses house block numbers instead of street names for addressing: Japanese addressing system - Wikipedia. Only major streets have names. Additionally you will find that junctions can have names for orientation while the streets between them are unnamed.
Nederland. All addresses include streetnames and postal codes; every public road or street accessing at least one address has a name. Addresses can also be objects such as wind turbines and even street cabinets (even wind turbines built in the sea).
Paths (including cycleways and footways) may or may not have names. Tracks leading into privately owned land or nature areas usually do not have names.
Major motorways without addresses sometimes have names, sometimes only reference numbers which are used as a name (eg “the A12”)
Municipalities issue the local street names and all street names are collected into a national database, which is freely available to OSM mappers.
In Poland there are places where roads are named but addresses are not using them.
See say Way: 172717224 | OpenStreetMap which is not using nearby street name (and AFAIK no address uses this street name).
(Osiedle Centrum C 7, Kraków)
Villages where the streets have no name also exist in Germany. We also use addr:place there.
I know a few places where nearly all streets have names, but some streets don’t. This seems to be possible only if there are no addresses on these streets, e.g. houses along there have their entrance on another street.
One of the weirder address schemes can be seen in Mannheim city centre - there are street names, but the adresses are using numbered blocks.
In Greece, several villages (small and medium) don’t have named streets. It’s more possible to find a named street in large villages. But in all cases of villages, no one is being used for addresses. The typical addresses for a house/shop in a village is just the name of the village, nothing else.
You may find signed streets in villages, usually old signs with barely any visible text, and that’s the only way to find the existence of a named street. Not even on the internet you will find those names, as they are not used in addresses (which would be the assumed main reason of a street’s name existence instead of just commemorating a person/event/place).
It’s not mandatory in Greece for a street to have an official name, that’s why you will find even in large cities cases of streets not having a name. Usually the officially unnamed streets within cities are named as “Πάροδος Χ οδού” (“X byway”, meaning byway of X main street). Sometimes those byways also have numerical naming, like “5η πάροδος” (“5th byway”), which is also commonly found in sparse residential areas (usually at touristic places).
This is where Norway is heading too. Although it may not be fully implemented yet, the goal is to have addresses based on street names throughout the country.

Any any municipality house number?
I know that Thailand has nameless streets, at least in small villages.

The rule of thumb is: the simpler the road network, and the smaller the village is, the more probable it is there will be no street names (although there are many regional variations).
There are even villages with mixed addressing: one part with named streets, with street-respective house numbering, and the other part unnamed, with its own pool of numbers.
It’s often the case in large villages that just recently decided to name their streets. They’re slow to roll out the changes.
Even though many houses have signed (sort of) numbers, they are not commonly used for addresses (although I think in few cases they do use them).
I suspect you’ll find some more-rural places of pretty much every country that don’t (yet?) have named streets. I very much enjoyed reading “The Address Book” by Deirdre Mask, which includes multiple contemporary stories (as well as history) about the efforts to get streets named and the challenges involved.
Yep, even in the U.S., where Hollywood would lead you to think every street has a name and white picket fences, some rural areas only have street names for local residential streets but not the highways that run through town or vice versa (and it’s even debatable whether those are names). In other areas, the roads have no identity whatsoever, so alternative coordinate-based addressing systems are in use.
In Ireland, many rural and village roads have no names and the buildings have no names or numbers. Address points (usually letter boxes) all have their own individual postcode (EirCode). Every public road should have a road number, although in many cases, this might not be published.
In Northern Ireland, pretty much every road has a name. Some of them were mandatorily added in the 1970s to roads that didn’t have names.
