Numer IBAN jest na wyciągu bankowym.

Polish does not have articles like the or a/an. So numer IBAN can mean the IBAN number or an IBAN number, depending on context.

In this sentence, the context usually makes it clear that it means the IBAN number.

• Numer IBAN = IBAN number
• jest = is
• na wyciągu bankowym = on the bank statement

So the sentence is perfectly natural without any article.

Numer means number, and IBAN is the international banking term IBAN.

So numer IBAN literally means IBAN number.

Even though in English some people avoid IBAN number because N already stands for number, in everyday language both English and Polish often still use this kind of phrasing. In Polish, numer IBAN is very normal.

Jest is the 3rd person singular form of być (to be), so it means is.

The sentence structure is:

• Numer IBAN = subject
• jest = is
• na wyciągu bankowym = on the bank statement

So literally: The IBAN number is on the bank statement.

In Polish, jest is often included in this kind of straightforward statement. It could sometimes be omitted in very informal or headline-style language, but in a normal full sentence, jest is the standard choice.

This is a very common question, because English often uses in where Polish uses na.

With documents, pages, lists, screens, and surfaces where information appears, Polish often uses na, especially when something is shown on or written on something.

So:

• na wyciągu bankowym = on the bank statement

It suggests that the information appears on that document.

Compare:

• na stronie = on the page
• na liście = on the list
• na fakturze = on the invoice
• na wyciągu bankowym = on the bank statement

Using w wyciągu bankowym would sound unusual here.

After the preposition na in this meaning, Polish uses the locative case.

The base form is:

• wyciąg bankowy = bank statement

But after na, it becomes:

• na wyciągu bankowym

The changes are:

• wyciąg → wyciągu
• bankowy → bankowym

This is because both the noun and its adjective must match in case, number, and gender.

So:

• nominative: wyciąg bankowy
• locative: na wyciągu bankowym

Wyciąg bankowy means bank statement.

Word by word:

• wyciąg = extract, statement
• bankowy = bank / banking-related

In banking, wyciąg bankowy is the normal term for a statement from your bank account.

So the full phrase na wyciągu bankowym means on the bank statement.

Because bankowy is an adjective describing wyciąg, and in Polish adjectives must agree with the noun they describe.

The dictionary forms are:

• wyciąg — masculine singular
• bankowy — masculine singular adjective

But after na, the noun is in the locative, so the adjective must also be in the locative:

• wyciąg bankowy
• na wyciągu bankowym

This kind of agreement is one of the most important features of Polish grammar.

Yes. Polish word order is more flexible than English word order.

The basic sentence is:

• Numer IBAN jest na wyciągu bankowym.

But you could also say:

• Na wyciągu bankowym jest numer IBAN.

Both are correct. The difference is mainly one of emphasis.

• Numer IBAN jest na wyciągu bankowym focuses first on the IBAN number
• Na wyciągu bankowym jest numer IBAN focuses first on the bank statement or on where to find the number

English is usually less flexible, but Polish often moves elements around to highlight different information.

Yes, you could say:

• Numer IBAN znajduje się na wyciągu bankowym.

This means almost the same thing: The IBAN number is located on the bank statement.

The difference is style:

• jest = simpler, more neutral, very common
• znajduje się = a bit more formal or explicit

In everyday practical instructions, both can appear, but jest is shorter and very natural.

The most natural translation is on the bank statement.

That is because Polish uses na here, and because the information is understood as appearing on a document. English sometimes says in the bank statement, but on the bank statement is usually the closer and more natural match for this Polish sentence.

Because IBAN is an international acronym. Polish keeps the capital letters, just as English does.

So:

• IBAN stays IBAN
• numer is lowercase because it is just a normal noun
• wyciągu bankowym is lowercase because these are ordinary words, not proper names

In Polish, IBAN is commonly pronounced like a normal word, approximately ee-bahn.

So the whole sentence would sound roughly like:

• Numer EE-bahn jest na vyh-CHYON-goo ban-KO-vym

That is only a rough guide, but the key points are:

• numer = NOO-mer
• jest = roughly yest
• wyciągu has a nasal vowel and a soft consonant cluster, which is harder for English speakers
• bankowym has stress on the second-to-last syllable: ban-KO-vym

Like most Polish words, the stress is normally on the penultimate syllable.

Yes, but it does not mean exactly the same thing.

• numer konta = account number
• numer IBAN = IBAN number

These are related, but not always identical in function. IBAN is the standardized international format of the bank account number.

So if the sentence specifically refers to the IBAN, then numer IBAN is the correct phrase.

You would say:

• Numery IBAN są na wyciągu bankowym.

Changes:

• numer → numery = numbers
• jest → są = are

The phrase na wyciągu bankowym stays the same.

So:

• singular: Numer IBAN jest na wyciągu bankowym.
• plural: Numery IBAN są na wyciągu bankowym.

It is neutral and perfectly natural.

It would fit well in:

• banking instructions
• customer service messages
• website help text
• spoken explanations

It is neither especially formal nor especially casual. That makes it a very useful sentence pattern to learn.
