# Postal Dataset

This is a dataset for noccylabs/dataset holding postal code patterns for
validating postal codes.


## Datasets

### postalcode

Field | Type | Description
---|---|---
`iso` | string | The ISO 2-letter country code
`format` | array | Valid formats, see below
`regex` | string | Unguarded regex to validate against


- The value in `format` is treated literal, except for the following characters:
  `#` indicates a number, `?` indicates a digit, and `*` indicates either a number
  or digit.
- The regex must be bounded, for example as `"<^".$regex."$>"`. This is done so
  that multiple expressions can be combined easily.
