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, until such time that you get a national Croatian identification card. When registering for state health insurance or applying for residency, you’ll need your OIB along with your passport for identification.
Do I need an osobni identifikacijski broj?
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 the usual tourist stay for your nationality 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 one 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
Applying for one is easy and should be done as soon as you arrive in Croatia. No need to begin the residency application process first. All you need is your passport and a completed application. There is no fee or cost for the application.
To apply for an OIB identification number, you’ll need to follow these steps:
- First, complete Parts 1 and 3 of the application. Download a copy of the form here in Croatian and here in English.
- Make a copy of your passport or EU identity card to accompany your application.
- Visit any of the Porezna Uprava 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 the document with your number in a safe place. If you ever lose the document, you can apply for a replacement. Most likely, you’ll never need this document again after you get your first residence permit. Your OIB number will be printed on your residence permit and your health insurance card.
UPDATE 31/3/20: During the pandemic, foreign nationals can apply for an OIB over email. You will need to send your application, identity documents, phone number and the Porezna Uprava office where you’d like to pick up your OIB to: [email protected]. Your OIB will be read for pickup within 8 days.
