The Area format is used for large regions, such as municipalities. The Street level format is used for more specific locations, like streets or blocks. Not all countries use both formats. When both are available, the Area format usually serves as a prefix to the Street level format.

* A = letter

| Ghana uses a digital address system. A digital address is made up of two main components: a postcode (e.g. EN-200) and a unique address (e.g. 1987). The first letter in the postcode represents a region (E for Eastern Region in this case), the second letter/digit (N) represents the district (N for New Juaben). The next batch of numbers (200) represent the area code. The regional, district and area codes come together to form the postcode. The last batch of numbers (1987) represent the unique address of the location. A combination of the postcode and the unique address make up the digital address.<ref>{{Cite web |title=Get Help {{!}} GhanaPostGps |url=https://ghanapostgps.com/get-help/ |access-date=2023-02-21 |language=en-US}}</ref>

| The dummy postal code of Hong Kong is 999077.
However, if you provide this dummy code where your address label will be electronically created, the system may change the destination country to "Hong Kong S.A.R, CHINA". The addition of "CHINA" can significantly delay delivery. Use an alternate dummy instead (e.g. 00000).<ref>{{cite web | archive-url=https://web.archive.org/web/20160120064618/http://www.upu.int/fileadmin/documentsFiles/activities/addressingUnit/hkgEn.pdf | archive-date=2016-01-20 | url=http://www.upu.int/fileadmin/documentsFiles/activities/addressingUnit/hkgEn.pdf | title=Hongkong, China | access-date=2024-03-03}}</ref>

Ireland's postcode system (called Eircode) refers to individual properties – not to streets/areas. It is presented in the format A12 A1BC
The first 3 characters are a routing key referring to a postal district, and the second 4 characters are a unique,
pseudorandom identifier for individual properties.  
The codes are only used in full 7-character format. See: www.eircode.ie for more information. See also [[Republic of Ireland postal addresses]].

The inward postcode is always formatted as NAA. A valid inward postcode never contains the letters: C, I, K, M, O or V.

Also used by the former US Pacific Territories: [[Federated States of Micronesia]]; [[Palau]]; and the [[Marshall Islands]], as well as in current US territories [[American Samoa]], [[Guam]], [[Northern Mariana Islands]], [[Puerto Rico]], and the [[United States Virgin Islands]]. An individual delivery point may be represented as an 11-digit number, but these are usually represented by [[Intelligent Mail barcode]] or formerly [[POSTNET]] bar code.

The first digit is assigned regionally (for example, ZIP codes beginning with 9 are found in the western coastal states, Alaska, Hawaii, and islands in the Pacific), and ZIP codes with the same first three digits are served by the same USPS sorting facility (which sometimes serve multiple such groupings), so will be geographically clustered (for example, all ZIP codes in 919XX, 920XX, and 921XX are found in San Diego County, California).

==On the use of country codes==
The use of the country codes in conjunction with postal codes started as a recommendation from CEPT ([[European Conference of Postal and Telecommunications Administrations]]) in the 1960s. In the original CEPT recommendation the [[List of international license plate codes|distinguishing signs of motor vehicles in international traffic]] ("car codes") were placed before the postal code, and separated from it by a "-" (dash). Codes were only used on international mail and were hardly ever used internally in each country.

Since the late 1980s, however, a number of postal administrations have changed the recommended codes to the two-letter country codes of [[ISO 3166]]. This would allow a universal, standardized code set to be used, and bring it in line with country codes used elsewhere in the UPU ([[Universal Postal Union]]). Attempts were also made (without success) to make this part of the official address guidelines of the UPU. Recently introduced postal code systems where the UPU has been involved have included the [[ISO 3166]] country code as an integral part of the postal code.

At present there are no universal guidelines as to which code set to use, and recommendations vary from country to country. In some cases, the applied country code will differ according to recommendations of the sender's postal administration. UPU recommends that the country name always be included as the last line of the address.

In the list above, the following principles have been applied:

* Integral country codes have been included in the code format, in bold type and without brackets. These are also used on internal mail in the respective countries.
* The [[ISO 3166]] codes is used alone for countries that have explicitly recommended them.
* Where there is no explicit recommendation for [[ISO 3166]] codes and the codes differ, both "car codes" and [[ISO 3166]] codes are listed, with the "car code" listed first.  In some countries, such as Zimbabwe and Zambia, a system is being planned.  1 10 and 11 used to be used as postal codes for Harare, Zimbabwe but a four-digit code system such as 2401 for Zimbabwe, 2402 for Epworth and "Overspill Road," as well as the suburb of "Zinnia Close and Gardenia Close" are given the provisional postal code of 2401.  2501 is the planned postal code for Bulawayo and 2423 for Victoria Falls.
