What is an OIB?
OIB stands for “osobni identifikacijski broj”. It is a personal identification number given to residents and citizens in Croatia, similar to a social security number in the United States. The OIB consists of eleven random numbers that do not correlate to your personal identity for security purposes.
When you get an OIB, you’ll be given a one-page two-part document that can serve as identification in conjunction with a photo ID like your passport. The top half is informational and can be detached. The bottom half is your official OIB number. When registering for state health insurance or applying for residency, you’ll need to provide bottom half of the document.
Do I need an OIB?
You will need an OIB if:
- You plan to buy property in Croatia
- You plan to open a bank, phone or utility account in Croatia
- You plan to reside in Croatia longer than 90 days and are applying for residency
- You plan to own a business and/or pay taxes in Croatia
It is not necessary to have an OIB to rent property, however. If you are without an OIB for any reason when signing a rental contract, your passport number can be used as an identification number instead.
How to get an OIB in Croatia
Getting an OIB is easy and can be done as soon as you arrive in Croatia. No need to begin the visa application process first. All you need is your passport and a completed application. There is no fee or cost to get an OIB.
To apply for an OIB identification number, you’ll need to follow these steps:
- First, complete Parts 1 and 3 of the application for an OIB. Download a copy of the OIB form here in Croatian and here in English.
- Make a copy of your passport to accompany your application.
- Visit any of the Ministry of Finance (or Ministarstvo Financija in Hrvatski) tax offices in Croatia. Here is the complete list of tax offices by city including contact phone numbers and addresses.
Once you submit your application, you can get your OIB number within minutes depending on how busy the office is when you apply. If you are not able to get it immediately, it will be prepared for you to pick up at a later date or mailed to your official registered address.
Keep your OIB in a safe place. If you ever lose your OIB document, apply for a replacement as soon as possible. Most likely, you’ll never need this document again after you get your first residence permit. It will be printed on your residence permit and your health insurance card.
