How this service works
Convert an ISO 3166-1 country code between alpha-2, alpha-3 and numeric; also name, currency, ccTLD, calling code.
Output
Returns a structured object containing the matched country's alpha-2, alpha-3, and numeric codes, official and common name, currency code(s), ccTLD, calling code(s), region, sub-region, capital, and independence status. A summary and attribution are also included. The `to` parameter lets you filter down to only the specific field type you need.
Example use cases
Normalize country codes in a data pipeline
“I have a dataset using ISO alpha-3 country codes like 'FRA' and 'BRA' — can you convert each one to its alpha-2 equivalent so I can match it against our internal system?”
Enrich checkout with currency and calling code
“A user signed up with country code '840' — can you convert that to alpha-2 and alpha-3 and also tell me what currency and international calling code that country uses?”
Resolve ccTLD for domain registration logic
“What is the country code top-level domain (ccTLD) for the country with alpha-2 code 'JP'? I need it to decide which domain extension to recommend.”
Technical details
Endpoint
GEThttps://country-codes-iso.x402tookit.com/code-convert?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to convert between ISO 3166-1 code formats (alpha-2 ↔ alpha-3 ↔ numeric) or retrieve standard country metadata like currency, ccTLD, or calling code from a known ISO code. Prefer this over the fuzzy-match or name-normalization sibling endpoints when you already have a valid ISO code and need a precise, structured conversion rather than name resolution or search.
Side effects
- Invalid or unrecognized country code returns a non-match or error result
- Ambiguous numeric codes may resolve to unexpected countries if input format is unclear
- Payment failure (402) if USDC balance is insufficient
- Rate limiting or service unavailability returning 5xx errors
- Deleted or reserved ISO codes may return degraded or partial results
