Endpoint
GEThttps://address-formats.x402tookit.com/postal-code-examples?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need concrete, real-world postal code examples for a specific country along with pattern validation — ideal for populating UI hints, generating test data, or verifying that a country's postal code format is what you expect. Prefer this over a raw pattern-check endpoint when you want both the pattern and example codes in a single call.
Side effects
- Missing or invalid 'country' query parameter returns an error
- Unsupported or unrecognized country code returns no results or an error
- Country has no postal code system — returns empty examples or a relevant message
- Limit parameter out of range (< 1 or > 50) may be clamped or return an error
- Service degraded flag set to true when data freshness or completeness is reduced
