ISO 3166-1 is part of the ISO 3166 standard, which defines codes for the names of countries, dependent territories, and special areas of geographical interest. ISO 3166-1 specifically provides a set of two-letter (alpha-2), three-letter (alpha-3), and numeric country codes.
ISO 3166-2 is a subset of the ISO 3166 standard. It defines codes for the principal subdivisions of all countries coded in ISO 3166-1. These subdivisions can include states, provinces, regions, or other similar entities. The code generally consists of the ISO 3166-1 alpha-2 country code followed by a hyphen and the subdivision code. The format and composition of the subdivision code vary from country to country.
Many security systems offer enhanced geographic details through ISO 3166-2 codes. By utilizing these codes, you can achieve more accurate mapping.

You can parse Amazon AWS WAF logs using the following query:
parse @message /labels.*region:(?<region>.*?)"/
| stats count(*) as requestCount by region
Approximately 99% of the location data was obtained from Wikidata, with the rest being manually curated. The mapping of country codes to Wikidata was derived from various sources, also involving manual curation.
| Level | Gazetteer | Total(according to Wikipedia) |
|---|---|---|
| Country | 250 | 242 |
| Subdivision | 5366 | 5043 |
In this gazetteer, some legacy codes are retained to enhance system compatibility.
Of course! The generation script is available in this repository, as well as the source countries and subdivisions files.
