It is also possible to replace the street name line with a PO box (e.g. Box 51). In Switzerland, the address is generally formatted as follows:  The canton abbreviation (SO, VD in the examples) is needed only for cities/town that have the same name but in another canton for example: Renens and Renan which were both, in the past, called Renens, the difference stays today and Renens is often mentioned as Renens VD.

In Thailand, address are generally formatted as follows:   Turkish addressing system is as follows: However, in rural areas with decidedly little population and with no street addresses, address format is much simpler:  Some neighbourhoods in the Ukraine may 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. Bandery, d. 123" ("123 Bandera St") An address may also cover one or more "subsidiary buildings" behind the main building, addressed as "vul. Bandery, d. 123, bud. 2" ("123 Bandera St, unit 2", where "bud." (abbreviation for будинок, "budynоk") means a '(subsidiary) building'). In newer areas with more regular street plans, apartment buildings that don't 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, bud. 123, kv. 56", i.e. "123 - 4th Microraion, apt. 56". In the United Arab Emirates, Emirates Post Group recommends the following format:  Not all of the roads and buildings in the UAE are numbered consistently and no postal codes are used in the United Arab Emirates.
