Post Office, Bank, and Services

A trip to the post office or the bank feels like pure survival vocabulary, but a routine errand in Polish quietly drills three things at once: the unpredictable w/na split (you go na pocztę but do banku, you are na poczcie but w banku), the conditional of polite request (Chciałbym… "I'd like…"), and the instructional infinitive the clerk uses back at you (Proszę wypełnić "please fill in"). Once you see that these three patterns are baked into the whole exchange, the case endings and verb forms stop looking arbitrary.

"At the post office" — na poczcie, not w poczcie

This is the trap English speakers never see coming. In English, "at the post office" and "at the bank" behave identically. In Polish they do not. The post office is a na-place, the bank is a w-place (here, more precisely, a do/w place):

For location ("where") both take the locative case: na poczcie (from poczta), w banku (from bank). For motion ("where to") the destination swaps to a different preposition and case — na + accusative for the post office, do + genitive for the bank:

Why the difference? There is no deep logic — poczta is simply one of the institutions Polish files under na (like na uniwersytecie, na dworcu "at the station", na lotnisku "at the airport"), while bank, urząd ("office"), sklep ("shop") take w/do. You have to learn the assignment per word. The good news: the post office is one of the most common na-words, so it is worth memorizing as a fixed pair — na pocztę / na poczcie. See the w vs na location page for the full breakdown of which institutions go which way.

"I'd like to send…" — the conditional request: Chciałbym

At the counter you almost never say the blunt present tense Chcę wysłać ("I want to send"). It sounds demanding. The polite, default register is the conditional of chcieć: Chciałbym (male speaker) / Chciałabym (female speaker), literally "I would like":

The conditional ending is gendered because it grew out of the past tense: chciał- + -bym for a man, chciała- + -bym for a woman. Get the gender right — it refers to you, the speaker. The same frame works for any service request:

Full coverage of how this form is built lives on the conditional formation page. For an errand, just lock in the four shapes: Chciałbym / Chciałabym (I'd like) and Poproszę (the "may I have" used with nouns — Poproszę dwa znaczki "Two stamps, please").

Sending things — wysłać, nadać, przesyłka

Two verbs cover "send": wysłać (the everyday "send", used for letters, parcels, emails) and nadać (the slightly more official "post/dispatch", what you do at the counter). Destinations use do + genitive:

The thing you send is the przesyłka ("the shipment/item"). The price question is Ile kosztuje przesyłka? ("how much is the shipment?") or, asking about a specific letter/parcel, Ile kosztuje wysłanie tego listu?:

Note znaczek ("stamp"), plural znaczki — a diminutive in form but the ordinary word for a postage stamp. You buy znaczki (accusative plural) and stick them on a koperta ("envelope").

The clerk talks back — the instructional infinitive

Here is the second half of the exchange that catches learners off guard. When the clerk gives you instructions, Polish very often uses Proszę + bare infinitive instead of a command form. It is polite, neutral, and impersonal — the standard register for official instructions:

English uses an imperative ("Fill in the form, please"); Polish reaches for Proszę + infinitive (wypełnić, podpisać, poczekać). The key vocabulary of forms and signatures clusters here: formularz ("form"), wypełnić formularz ("to fill in a/the form"), podpis ("signature"), podpisać ("to sign"). This is the same instructional register you meet on public signs and notices, where verbs appear as bare infinitives (Nie palić "No smoking").

A counter exchange

Here is how the pieces fit together at the post office window:

Notice the rhythm: your side is built on Chciałbym + infinitive, the clerk's side on Proszę + infinitive, the price comes back in the genitive plural (złotych, under the after-numbers rule), and the institution stays a na-place throughout.

Common Mistakes

Key Takeaways

• na pocztę / na poczcie, but do banku / w banku — the w/na split is lexical; learn each institution's preposition as a fixed chunk.
• Counter requests use the conditional: Chciałbym (m.) / Chciałabym (f.) + infinitive. Get the gender right — it marks you.
• The clerk answers with the instructional infinitive: Proszę wypełnić, Proszę podpisać, Proszę poczekać.
• Destinations of sending take do + genitive (do Niemiec, do Francji); prices come back in the genitive plural (złotych).
