# PostalCodeValidator
[![Build Status][ci status badge]][ci status]
[![License][license badge]][license]
[![Swift Version][swift version badge]][swift version]
A validator for [postal codes](https://en.wikipedia.org/wiki/Postal_code)
with support for 200+ regions.
```swift
import Foundation
import PostalCodeValidator
if let validator = PostalCodeValidator(locale: .current) { // United States (US)
validator.validate(postalCode: "95014") // true
validator.validate(postalCode: "22162-1010") // true
validator.validate(postalCode: "1234567") // false
validator.validate(postalCode: "INVALID") // false
}
// 248 regions supported
if let validator = PostalCodeValidator(regionCode: "JP") { // Japan (JP)
validator.validate(postalCode: "154-0023") // true
validator.validate(postalCode: "12345") // false
}
```
> **Note**: Only the region of a locale is used to determine validation rules.
> To validate the postal code for a particular region,
> you can construct a locale using an identifier with the `"und"` language code.
## Requirements
- Swift 4.0+
## Installation
### Swift Package Manager
Add the PostalCodeValidator package to your target dependencies in `Package.swift`:
```swift
import PackageDescription
let package = Package(
name: "YourProject",
dependencies: [
.package(
url: "https://github.com/FormatterKit/PostalCodeValidator",
from: "0.1.0"
),
]
)
```
Then run the `swift build` command to build your project.
## Known Issues
- Armed forces in Germany (and likely other countries)
use [special postal codes](https://de.wikipedia.org/wiki/Feldpost_%28Bundeswehr%29),
which aren't included in the upstream data source.
This will cause validation of these postal codes to fail.

## Additional Details
The CLDR previously maintained a list of postal code formats,
but that information was
[deprecated in v27](http://unicode.org/reports/tr35/tr35-info.html#Postal_Code_Validation).
Following the guidance of the
[twitter-cldr-rb](https://github.com/twitter/twitter-cldr-rb/issues/166) project,
`PostalCodeValidator` sources its information from http://i18napis.appspot.com.
The most recent release of this software uses
information retrieved from the website on November 27, 2019.
