Limiting overpass turbo query by postal_code and country

Question

I'd like to limit a query (for highways) by postal_code and country (since the postal_codes are only unique on a national level).

Let's say that is my query:

area[postal_code="19300"]->.searchArea;
area.searchArea[name="Germany"];
way(area.searchArea)[highway][name];
(._;>;);
out;

By that I get highways in Germany and in France.

I thought about something like

area.searchArea[name="Germany"].->searchArea2;
way(area.searchArea2)[highway][name];

But this doesn't work.

What would be the correct syntax?

Or how could I link something like

{{geocodeArea:Germany}}

to this kind of query?

Overpass API does not support area in area queries. However, you can define two different areas and use both of them as filter criterion in the same statement:

area[postal_code="19300"]->.zip;
area[name="Deutschland"]->.de;
way(area.de)(area.zip)[highway][name];
(._;>;);
out;
