Can I keep my phone number when I switch provider in Croatia?
You can keep your number when you change operator, and porting must not cost you anything. The number must work in the new network within one working day of the date agreed with you. Your old contract then ends automatically.
You can usually take your mobile or landline number with you to a new provider. You ask the new provider to transfer it, and the number moves on an agreed day.
📜 The rules in Croatia
Compensation
€30 per started day of late, early or unwanted porting, for at most 15 days and up to 10 numbers per request. Claim it in writing or electronically from the new operator within 30 days of the switch.
The details
- Ask the new operator: the switch request it fills in with you is also your porting request, and it arranges the porting time with the old operator so you are not left without service. (hakom.hr)
- Porting may take at most 2 working days from when the old operator receives the request, unless you chose a later date. You are without service for at most 3 hours, on a working day between 8:00–11:00 or 12:00–15:00. (narodne-novine.nn.hr)
- Late, early or unwanted porting: €30 per started day, for at most 15 days and up to 10 numbers per request. Claim it in writing from the new operator within 30 days; payment is due within 30 days of your claim. (narodne-novine.nn.hr)
- After you cancel a contract, the old operator must still let you port the number for at least 30 days, unless you gave up that right. (hakom.hr)
- A minimum term cannot block porting; you only owe the agreed early-termination fee. With prepaid, the old operator must refund remaining credit on request; it may charge for this only if the contract says so, in line with its real costs. (narodne-novine.nn.hr)
- A geographic (landline) number can only be kept at the same location, and numbers cannot be moved between fixed and mobile networks. (narodne-novine.nn.hr)
- You can check the porting status of your number, and which network any number is in, with HAKOM's e-Prenosivost application. (hakom.hr)
Hrvatska regulatorna agencija za mrežne djelatnosti (HAKOM)
Telecom regulator: explains your rights on its user protection line (working days 9:00–11:30) and settles disputes with operators after the operator's two-stage complaint procedure.
Inspektor elektroničkih komunikacija (HAKOM)
Handles your report if switching compensation is refused, wrongly calculated or not answered within 30 days; email inspektor@hakom.hr.
🪜 Step by step
- Do not cancel the old contract firstIf you end the old contract before the transfer, the number can be lost. Let the new provider request the transfer.
- Get your details readyYou usually need the number, the name on the old contract and sometimes a customer number or transfer code from the old provider.
- Agree the transfer dateThe new provider tells you when the number moves. Keep the old SIM or line in use until then.
- Check that everything worksTest calls and messages on the new SIM or line, and check that the old provider sends a final bill and stops charging.

❓ Questions
How long does a number transfer take?
It is usually quick. If the rules in Croatia set a maximum time or compensation for delays, you find them on this page.
Can I keep my number if I still owe the old provider money?
You still have to pay what you owe under the old contract. Ask the new provider before you switch whether anything could hold up the transfer.
Can I move a mobile number to a landline, or the other way round?
Usually not: mobile numbers move between mobile providers, landline numbers between landline providers.
