How postal index pages are organized
The index section is built as a directory of countries, cities and individual postal code pages. A country page shows cities where postal data is available, while each city page highlights the main postal index and links to all known codes for that city.
Separate postal index pages help users and search systems understand where a specific code is used. They connect the code with countries and cities, which makes the data easier to compare and cite.
For AI search and classic SEO, the section uses clean URLs, breadcrumbs, canonical links, structured data and internal links between country, city and postal code pages.
