Sierznia marked on Poland, Warsaw shown for scale.
When an exit in Sierznia is worth asking for
For most sites, an IP address here identifies as Poland first and Sierznia second. Checks that stop at the country, and that is prices, catalogs, language and most geo-blocks, behave the same whether your exit sits in Sierznia or in Warsaw.
City targeting starts to matter when the question is genuinely local: store stock and pickup, delivery estimates, local search results, regional pricing, or anything a map decides for you. If that is your task, ask for Sierznia specifically. If it is not, the country exit is cheaper and far more stable.
City-level residential supply moves week to week everywhere, ours included. If nothing is live in Sierznia the moment you ask, the reliable fallback is the Poland country exit, and the free Poland list shows the public pool measured live.

FAQ
Sierznia proxy questions, answered
Residential plans support city-level targeting, so you can request Sierznia specifically, or widen the same request to Łódź Voivodeship without changing plans. What is live in any one city moves constantly, for every provider; the Poland country exit is the request that never depends on one place.
To a site that reads only the country: no. Sierznia and Warsaw look identical there. To anything local, map results, stock, delivery estimates, the city is exactly the difference, and that is the one case worth paying the supply constraint for.
In Łódź Voivodeship, Poland, 100 km southwest of Warsaw. The local timezone is Warsaw time (Europe/Warsaw).
Then take Łódź Voivodeship as a whole, or the Poland country exit. Single-city supply is fluid in this whole industry, and we would rather hand you the wider fallback in one click than promise a specific street and miss.
