Rostki - Rostkach

Urodzil sie w Rostkach
Wojewodstwa Bialystok
Powiat Lomzia
Urzad Stanu Cywilnego Lomzy

Does this mean born in Rostki, Province of Bialystok and if so were I to write this on my
letter to assure it getting to proper Rostki.

yes


you may need full postal address, although in some smaller towns, villages etc they know people by name.

Yes it does.

I imagine you want (or need) to write to “Urząd Stanu Cywilnego w £omży”. If so, it should be like this:

Urząd Stanu Cywilnego w £omży
xx-xxx £omża
Województwo białostockie
Poland

where xx-xxx stands for postal code (have no idea what it is though)

Ok, found it. The full address is:

Urząd Stanu Cywilnego w £omży
Stary Rynek 14
18-400 £omża
Województwo białostockie
Poland

Thank You.
