About

AtlasLookup is a free reference atlas of the codes people look up every day — national codes, administrative regions, telephone area codes, business and occupation classifications, customs (HS) codes, postal codes and bank codes — organised by country and available in 15 languages.

It currently covers all 250 countries and territories, with deep code directories for major economies. The data is compiled from authoritative open sources, including national statistics offices, standards bodies and open datasets, and is provided for reference only.

AtlasLookup is an independent project and is not affiliated with, or endorsed by, any government or official body. While we work to keep the information accurate and up to date, codes and administrative divisions change; always confirm critical information with the relevant official source.
