Terms of use

PostCode Check by Harlo is provided as is, without warranty of any kind. This is a format check: valid means the code has the right shape for the country. It does not confirm that the code is assigned, exists or is deliverable. Postal formats change; data: Google libaddressinput address metadata (Apache-2.0), snapshot 2026-10-26; country names from Unicode CLDR.

Fair use: about 60 requests per minute per IP. Don't attempt to bypass limits or overload the service. Access may be limited or withdrawn at any time.

Works with AI agents and assistants that can call an MCP server or a JSON API, for example Muse, Claude, ChatGPT or Cursor (descriptive only). PostCode Check is not affiliated with, endorsed by or sponsored by Google, the Unicode Consortium, any postal operator, Meta, Anthropic, OpenAI or Anysphere.

These terms may change; the current version is always at this page.
