With this tool, you can easily check if a South African Identity Number is valid. Submit a 13 digit South African ID number and get the result as well as their age, gender and whether they are a citizen or not.
This plugin was built using the tutorial at How To Validate A South African ID Number With PHP. View on GitHub or download the plugin at WordPress.org.
Is this still valid in 2020? Please let me know in the comments below.
