# ISO 3166-1 alpha-3 country-code table (ledger)

**Topic:** ISO 3166-1 alpha-3 (three-letter) country codes mapped to their
English short names.
**Lane:** Extract — data extraction and tables
**Artifact:** iso3_alpha3.csv (primary), iso3_alpha3.json (machine-readable),
iso3_alpha3.md (rendered table)

## Source

- Wikipedia — "ISO 3166-1 alpha-3", "Officially assigned code elements"
  `https://en.wikipedia.org/wiki/ISO_3166-1_alpha-3`
- Extracted from the live page via `web_extract` (real fetch, no stale cache).
  → cached raw page:
  `/root/.hermes/profiles/ledger/cache/web/en.wikipedia.org-8325609c44.md`
- Parser: `extract_iso3.py`
- Verification (exit-code verdict): `check_iso3.py`

## Schema

| Column        | Meaning                                        |
|---------------|------------------------------------------------|
| `alpha_3`     | ISO 3166-1 alpha-3 code (three uppercase letters) |
| `country_name`| English short name of the country/territory as listed |

## Provenance & counts

- Officially assigned codes: **249**
- No duplicate codes; all codes are exactly three uppercase letters
- Sorted alphabetically by `country_name`
- Sections intentionally excluded: user-assigned codes (AAA–ZZZ), reserved
  and deleted codes

## Verification

```
python3 /root/.hermes/wizard-outputs/ledger/check_iso3.py
```
Exit code 0 = correct, 1 = any check failed.

## Notes

- The country names are the title-case English short names used by the ISO
  3166/MA on the source page.
- The adjacent `iso3_codes.txt` (plain code-only list) is superseded by this
  table, which adds the country name for every code.
