be planned in such a way that some, or most, apartment buildings don't face a named street. In this case, a number of expedients can be used. In older neighbourhoods, a "main" building may have the same number as one or more "subsidiary" buildings accessible via driveways behind the main building. They will be addressed as vul. Lenina, d. 123 (123 Lenin St) An address may also cover one or more subsidiary buildings behind the main building, addressed as vul. Lenina, d. 123, bud. 2 (123 Lenin St, unit 2, where bud. (abbreviation for ) means a '(subsidiary) building'). In newer areas with more regular street plans, apartment buildings that do not face a named street may be designated with Cyrillic letters appended to the building number, e.g. 123-а, 123-б, etc., in Cyrillic alphabetical order. In some microraion neighbourhoods, with few, if any, buildings facing named streets, the name (or more likely number of the microraion (planned housing development)) would be used instead of the street name; thus someone may live at 4-th microrayon, d. 123, kv. 56, i.e. 123 - 4th Microraion, apt. 56. Source: Belposhta Belgium In Belgium, the address starts with the most specific information (addressee individual identification) and ends with the most general information (postcode and town for domestic mail or country for cross border mail.) Spatial information of a physical address (including building, wing, stairwell, floor and door) may be useful for internal path of delivery, but is not allowed in the delivery point location line (i.e. the line containing street, number and box number). If needed, this information will appear on a line above the delivery point location line. The street number is placed after the thoroughfare name (unlike in France), separated by a space. Separators such as punctuation (point, comma or other signs) or "nº", or "nr" are not allowed. Extension designation (box numbers), if present, appears in the delivery point location line, preceded by the word for "box" ( in Dutch, in French). Symbols such as b, Bt, #, -, / are not allowed as separators between the street number element and the box number element. Examples of a correctly formatted postal address: The Belgian addressing guidelines are registered with the Universal Postal Union (UPU and see the link Universal Postal Union – Postal addressing systems in member countries). These guidelines indicate exactly how to combine the various address components in order
