## FAQ

### Does validation require an API key?

No, parsing and validation are performed offline and do not require a key.

### What is the format of a Nigerian postcode?

A postcode consists of 11 characters in five segments: state, LGA, district, area, and building unit (e.g., EK-01-A03-FK-01).

### How can I use this with an AI assistant?

You can run the MCP server using `uvx ng-postcode-mcp` or `npx ng-postcode-mcp` and configure it in your MCP settings.
