Croatian bureaucracy runs on three things: your OIB number, your registered address, and patience at the counter. Get the first two right in week one and everything else — banking, utilities, the driving licence — follows. Here's the sequence.
Figures verified 9 July 2026The OIB is Croatia's equivalent of the Portuguese NIF — an 11-digit identifier the tax administration issues free, on the spot or within days, at any Porezna uprava office (a lawyer can obtain it under power of attorney before you arrive). Without it you can't open a bank account, sign a lease, connect electricity, or enrol with HZZO. Then register your address within 3 days of entry at the police station — Form 16a plus a lease, deed, or notarised owner's statement. Skipping registration isn't a paperwork slip; it can void a residence permit.
You can drive on a valid US or Canadian licence as a visitor. Once you're a resident, the licence must be exchanged at MUP — third-country licences are generally usable for up to 12 months from residence registration. Whether the exchange requires a practical driving test depends on the issuing country's arrangement with Croatia, and US states are not treated uniformly — check your specific case with your police administration early, because retaking a driving test in Croatian is nobody's idea of retirement. Budget for a medical certificate (liječničko uvjerenje) as part of the exchange.
Which US states and Canadian provinces exchange cleanly, and who faces a test.
The certificate timeline, airline rules, and the summer heat embargo problem.
Which banks handle FATCA smoothly, and what non-residents can open before the permit.
OIB, registration, licence, bank — it's all doable, and it's all faster with someone who's done it fifty times. We'll introduce a Croatia settling-in specialist we've independently vetted.
