Got a letter from your bank in Poland? What it usually means

A letter, email or in-app message from your Polish bank usually falls into one of a few categories. Most are routine and don't need urgent action — but a couple of types do.

The most common types

• Request to update your customer information (KYC) — banks are legally required to periodically confirm details like your address, source of funds, or tax residency (this is standard anti-money-laundering practice, not something unique to foreign customers).
• A decision on a loan or credit application — approval, rejection, or a request for more documents before a decision can be made.
• A notice about account terms or fees changing — banks are required to give advance notice before changing terms; you usually have the right to close the account without a fee if you don't accept the change.
• A security or fraud alert — flagging unusual activity, sometimes asking you to confirm a transaction was really you.

What to check first

1. If it's asking you to confirm your identity or update documents, check it's a genuine request from your actual bank (via their official app or by calling the number on your card — never a number given only in the message) before sending anything, since bank-impersonation scams are common.
2. If it's a KYC/AML request, respond within the stated deadline — banks can restrict an account if this kind of request is ignored.
3. If it's about a loan or account terms, read it fully before assuming — Polish banking letters are often more formal in tone than the situation actually is.

If you're opening a business account rather than a personal one, see opening a business bank account as a foreign-owned company — banks there often ask for a specific set of documents up front, for the same KYC reasons.
