Croatian addresses write the street before the house number and place a five-digit postal code before the town. For international mail the code often carries an HR- prefix, and Croatian names and streets use letters like č, ć, š, ž and đ that Latin-only forms tend to mangle. Here is the correct format, a real example, and the mistakes that cause returns.
A Croatian label is recipient, optional company, the street with its house number, then the five-digit postal code and town on one line, then the country. There is no region or county line.

The leading digit marks the region (Zagreb codes begin with 1), and cross-border senders add the HR- prefix so the origin country reads the destination correctly.
The country-specific rules that generic autocomplete and single-line address fields tend to get wrong.
Croatian addresses write the street then the number: Ilica 5, never 5 Ilica. House numbers can include a letter (5a) or a slash for sub-units, so a number-first form built for the US misreads the line.
For cross-border shipments the five-digit code is often written HR-10000. The prefix is optional domestically but helps foreign carriers route to Croatia, so it should be accepted and not treated as an invalid character.
Every Croatian code is exactly five digits, for example 10000 for central Zagreb, and the leading digit marks the region. A four-digit code is out of date and a leading zero must be kept, so a field that trims digits corrupts the code.
Croatian names and streets use these letters, and đ is often mis-transliterated to dj. Inconsistent stripping, such as Đakovo becoming Djakovo in one system and Dakovo in another, causes mismatches against carrier data.
Each of these passes a basic "is this field filled in" check but fails at the carrier, turning into a redelivery, a return, or an address correction fee.

International carriers for inbound shipments. Include the country line and keep diacritics consistent; they charge address-correction fees when a code or street forces a manual fix.
