Personnummer

GitHub Workflow Status

Validate Swedish personal identity numbers.

Installation

Add the package to your maven or gradle configuration.
If you prefer to use the package from github rather than maven-central, add the repository as well.

<dependency>
  <groupId>dev.personnummer</groupId>
  <artifactId>personnummer</artifactId>
  <version>3.*.*</version>
</dependency> 
plugins {
    id 'maven'
}

repositories {
    // If using maven central
    mavenCentral()
    // If you wish to use github
    maven {
      url "https://github.com/personnummer/java:personnummer"
    }
}

dependencies {
    configuration("dev.personnummer:personnummer")
}
