Addressing knowledge centre

Addressing practices differ essentially from country to country: there are more than 200 address formats in the world, 200 database structures and at least 20 language scripts are officially used to write addresses.

This diversity is very difficult to comply with when dealing with addressing at the international level. Our Addressing Knowledge Centre is designed to answer questions arising as a result of this variety and complexity. 

It consists of three parts: Universal POST*CODE® DataBase-specific FAQs, General Addressing Issues and Thoroughfare Types and Abbreviations.

  • Updated August 2022 - Where I can find the list of field lengths/types of the Universal POST*CODE® DataBase data? etc.
  • Updated November 2022 - Where can I find lists of different types of thoroughfares, and their abbreviations used in different countries?
  • Updated November 2024 - Which countries in the world have/do not have a postcode system?
    Is there a standard that a country should follow when it does not adopt a postcode?

Postal Addressing Systems (PAS)

A proper addressing system guarantees speed and efficiency in the processing of postal items among UPU member countries (including their territories) and other non-member country territories (as exceptionally authorized by the Acts of the UPU or the decisions of its bodies). The information available on these pages allows you to:

  • Prepare addresses in accordance with the standards of the designated operator of the country of destination;
  • Obtain additional information on a country’s addressing system or postal operations;
  • Check that a postcode is correctly structured, by checking the number and nature of its components;
  • Verify that the elements comprising a postal address are written correctly.

International addressing

Looking up a postcode

The postcode is the fundamental, essential element of an address. It is a key component of a postal addressing system.

A unique, universal identifier, it unambiguously identifies the addressee's locality and assists in the transmission and manual or automated sorting of mail items.

At present, around 130 countries use postcodes as part of their addressing systems.

To validate an international address, consult the websites of one of our partners.

Addressing S42 standard

The UPU has developed two addressing standards: S42 and S53.

Standard S42: International postal address components and templates

The S42 international addressing standard consists of two parts:

S42 part A defines:

  • a set of postal address components used in worldwide addresses;
  • languages for expressing address templates, i.e. formal descriptions of address formatting rules.

S42 part B:

  • provides country-specific address templates. A country defining its S42 template provides precise information about its address elements and formatting rules.
  • creates a library of templates that can be easily incorporated into computer systems for managing addresses.

Standard S 53: Exchange of name and address data

S53 facilitates exchange of name and address data between postal authorities, businesses, mailers and other organizations. It incorporates the S42 elements and templates.

  • The S42 international addressing standard comprises of a generic list of address elements (used in all UPU member countries) and country-specific templates that tell users how to transform address elements into an accurately formatted address.

Steps to create S42 template


This page outlines the process for creating a new template.

Country: submit sample

To launch its template development, the country contacts the S42 expert group by e-mail. The country's expert supplies a sample data set, which should consist of between 20 and 50 address examples representing all the address formats recommended by the postal operator. 

Country and UPU: map addresses into elements

Each address in the sample needs to be mapped into S42 elements reflecting their use in the country. For example, mapping the address line "12 Main Street" involves dividing it into 3 parts: "12", "Main", and "Street", and linking them to appropriate address elements as follows: "12" – street number; "Main" – thoroughfare name; "Street" – thoroughfare type.

UPU: create a draft template based on mapped sample

On the basis of a mapped sample, the S42 expert group creates a template which is fed into a computer program known as a tester. This program reassembles each address from elements and checks the result against the submitted data. The test of the template is positive when all addresses from the sample have been assembled correctly.

Country: validate and approve template 

At the end of the process, the country expert checks that:

  • all addresses in the sample data set are properly formatted;
  • the sample contains a sufficiently complete representation of formats recommended by the country; and
  • the addresses are correctly mapped to S42 elements.

UPU: publish template and deliver certificate

The template developed through this process is published in the next version of standard S42, and the country that developed the template is presented with a “S42 certificate of recognition” during one of the annual Postal Operations Council or Council of Administration sessions.

Compliant countries

S42 templates have been developed for the countries listed below.

For each S42 compliant country this web page provides access to standardized address format description (SAFD). The SAFD includes address formats, mapping of S42 elements to national elements specified by countries and metadata incorporated in the S42 template.

Access to XML S42 templates is provided for registered users only. See application form.
