``sh`
$ npm install greece-postal-code
To validate a postal code:
`js
var postalCode = require('greece-postal-code');
postalCode.validate('10188'); // true
postalCode.validate('ab1234'); // false
`
Please note that the validation is strict, for example it will not allow spaces. Use clean() to remove any whitespace from the postal code string before validating it:
`js``
postalCode.validate('101 88 '); // false
var cleaned = postalCode.clean('101 88 '); // '10188'
postalCode.validate(cleaned); // true
