Bulgarian addresses are written in either Cyrillic or Latin script, and a large share of ecommerce ships to a courier office or locker rather than a home. Add the four-digit postal code before the town and the block-based numbering used in housing estates, and generic checkout forms drop detail fast. Here is the correct format, a real example, and the mistakes that cause returns.
A Bulgarian label is recipient, optional company, the street or housing-estate address with its number, then the four-digit postal code and town on one line, then the country.

It sits before the town, and because many town and village names repeat across the country, the code plus the municipality is what pins the address down.
The country-specific rules that generic autocomplete and single-line address fields tend to get wrong.
Bulgarian addresses are written in Cyrillic domestically and transliterated to Latin for international mail. Either script works, but mixing them on one label, such as a Cyrillic street with a Latin town, can garble in carrier systems that expect one alphabet.
Many Bulgarian homes sit in a zhilishten kompleks (zh.k., housing estate) with no street number. The address is a block, entrance, floor and flat: zh.k. Mladost 1, bl. 25, vh. B, et. 3, ap. 15. A form with only a street field cannot capture this.
Econt and Speedy move much of Bulgarian ecommerce to a named office or automat rather than a home. That destination is an office code or location, not a street, so a checkout that requires a street address blocks a common delivery choice.
Bulgaria writes the four-digit code ahead of the town: 1000 Sofia. Because many settlements share a name, the code and municipality together resolve which one, so a wrong or missing code leaves the town ambiguous.
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.

The dominant domestic couriers for Bulgarian ecommerce, both built around office and locker pickup. They expect a full street or housing-estate address, or a valid office code when shipping to a pickup point.
International carriers for inbound shipments. Include the country line and keep to one script; they charge address-correction fees when a code or address forces a manual fix.
