Croatia phone number format

  • Country code +385
  • Trunk prefix 0

What does a Croatia phone number look like?

8 or 9 digits after the trunk 0. Landlines are written +385 X XXX XXXX and mobiles +385 9X XXX XXXX. In full international (E.164) format a Croatia mobile is written +385912345678: the country code +385, with the national trunk prefix 0 removed, and no spaces or punctuation.
The anatomy of a Croatia phone number under ITU-T E.164: country calling code 385, then the national destination code, then the subscriber number, to a maximum of fifteen digits after the plus. Nationally a Croatia number is written +385 X XXX XXXX with the trunk prefix 0; in E.164 the prefix and the spacing both come off.
National formatting is for people. E.164 is for databases, APIs, and caller ID — store Croatia numbers in the right-hand form.

Validation

How to validate a Croatia number

Validating a phone number is three separate checks, and conflating them is the usual source of bugs:

  1. Format: does it match the shape for Croatia? 8 or 9 digits after the trunk 0, after the country code and with the 0 stripped.
  2. Allocation: is the prefix actually in use? A number can be the right length and still belong to an unallocated range.
  3. Reachability: is there a live subscriber? Only a carrier lookup (HLR or equivalent) answers that, and it is the only check that catches disconnected numbers.

For form validation, check format only and be permissive: accept spaces, dashes, brackets, and a leading 0 then normalise. Rejecting a real customer because they typed their own number the way they normally write it is a far more expensive error than storing one badly formatted row.

Store in E.164 (+385912345678) and format for display at render time. Storing the display format is how a database ends up with the same person recorded four different ways.

Frequently asked questions

What does a Croatia phone number look like?
8 or 9 digits after the trunk 0. A landline is written +385 X XXX XXXX and a mobile +385 9X XXX XXXX. In full international format that becomes +385912345678.
How do I write a Croatia number in international format?
Start with +385, remove the leading 0 from the national number, then append the rest with no spaces or punctuation. +385 1 234 5678 becomes +38512345678.
How many digits is a Croatia phone number?
8 or 9 digits after the trunk 0.
How do I tell a Croatia mobile from a landline?
By the prefix. Mobiles follow the pattern +385 9X XXX XXXX, while landlines follow +385 X XXX XXXX.
Should I store phone numbers with the plus sign?
Yes. Store every number in E.164: leading +, country code, national number, no spaces or punctuation, up to 15 digits. It is the only format that is unambiguous internationally, and it is what makes deduplication work. Format for display, store canonical.
