I would suggest that as long as the area has clearly defined boundaries (in accessible official documents) and it was defined or is actively used by country's administrative officials or agencies then that would constitute for accepting it.

US counties (or the equivalent: Louisiana has parishes, and I don't
recall what Alaska's are called) are strictly hierarchical - they
don't cross state lines - and all fifty states have them. The federal
government asks for 'county' on a wide variety of forms, including
passport and security clearance applications. The block that a notary
public uses to witness signatures begins "State of ____, County of
____, SS: (City/Town/Village/Other) of ____:"

I don't map special-purpose administrative districts, of which New
York has a whole menagerie. I don't object if others do, but don't try
to fit them into the boundary=administrative hierarchy.  They don't
go. In New York, the admin_levels are as tabulated on the Wiki: 2=US
4=NY 5=New York City (don't ask!) 6=county 7=city, town, Indian
Reservation 8=village, hamlet (outside cities), ward, district,
precinct, community board (in cities). There are only a few ways in
which this scheme breaks hierarchy (New York City, one other city that
has annexed across a county line, a chartered city that has in
practice reverted to being a village, and about 15% of villages are in
two or more towns.). If things like school, library, police, fire,
water, sewer, or sanitation districts were to be included, the
hierarchy would be broken all over the place. And that only scratches
the surface of special-purpose administrative districts. As I said, go
ahead and map them, but don't try to make admin_level fit.
