The UPU addressing unit provides as a product Post*Code database that contains postal addressing data sets from all UPU member countries. The structure of DB was designed initially to carry only postcode directory level of data but than it was extended to carry delivery point level. Currently, a new format that also will be compatible with UPU S42 templates and contain geo coordinates.
UPU has also developed international postal addressing standards S42 and P14. The S42 international addressing standard is comprised 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. In other words, a country defining their S42 template provides precise information about their address elements and formats.
As templates are expressed in both human and computer readable languages they are ready to integrate in address formatting computer systems.
UPU is also developing a standard on electronic exchange of address data. The work item is known as P14 and the first draft is expected in December 2008.
