Understanding Croatian Phone Numbers

Croatian phone numbers are structured with the country code +385. When dialing from abroad, the national trunk prefix 0 used within Croatia is dropped.

Landline Numbers

• Format from US: 011 + 385 + Area Code (1-2 digits) + Local Number (6-8 digits)
• The area code for Zagreb is 1, followed by a 7 or 8-digit local number.
• Other regions have a 2-digit area code, typically followed by a 6-digit local number.
• Total digits after +385 for landlines: Typically 8 or 9. (e.g., 1 XXX XXXX or 2X XXX XXX).

Mobile Numbers

• Total digits after +385 for mobile: Usually 8 or 9 (e.g., 9X XXX XXXX).

Croatian Area Codes (Fixed Lines)

This is an exhaustive list of National Significant Numbers (NSNs) or area codes for landlines in Croatia. Remember to dial 011 + 385 before these codes, then the local number. The leading 0 found in domestic dialing is dropped.

Croatian Mobile Phone Prefixes

Croatian mobile numbers are typically 8 or 9 digits long after the +385 country code. They consist of a 2-digit prefix followed by a 6 or 7-digit subscriber number.

*Number portability is active in Croatia, so a prefix does not definitively indicate the current operator for a specific number. Newly issued numbers follow this plan.

Time Difference

Croatia operates on Central European Time (CET), which is UTC+1, during the winter months and Central European Summer Time (CEST), which is UTC+2, during the summer months (roughly late March to late October).

The time difference compared to the US East Coast (ET):

• During US Standard Time (EST, UTC-5) & Croatian Winter Time (CET, UTC+1): Croatia is 6 hours ahead of ET. (e.g., 12 PM EST is 6 PM CET in Croatia).
• During US Daylight Time (EDT, UTC-4) & Croatian Summer Time (CEST, UTC+2): Croatia is 6 hours ahead of ET. (e.g., 12 PM EDT is 6 PM CEST in Croatia).
• During brief transition periods when Daylight Saving Time changes don't align perfectly between the US and Europe, the difference can occasionally be 5 or 7 hours, but for most of the year, Croatia is 6 hours ahead of the US East Coast.

Croatia's Phone System

Croatia has a modern and well-developed telecommunications system. The infrastructure is largely digitized, with major operators like Hrvatski Telekom (owned by Deutsche Telekom), A1 Hrvatska, and Telemach Hrvatska providing comprehensive services. Fiber-optic networks are expanding, particularly in urban areas, supporting high-speed internet and voice services. Mobile phone penetration is very high, with extensive 4G/LTE coverage across the country and ongoing 5G network deployment. Mobile Virtual Network Operators (MVNOs) also offer competitive services, utilizing the infrastructure of the main carriers.

Best Times to Call

Considering the time difference (Croatia is generally 6 hours ahead of US ET):

• A good window for business calls from the US is typically morning ET (e.g., 9 AM - 11 AM ET), which corresponds to mid-afternoon in Croatia (3 PM - 5 PM CET/CEST).
• Croatian business hours are generally Monday to Friday, 8:00/9:00 AM to 4:00/5:00 PM.
