About This Tool
This tool validates Chinese ID numbers with support for both 15 and 18 digits. It parses region (province/city/district), birthday, and gender, and verifies the checksum. It also converts 15-digit IDs to the standard 18-digit format. All computations happen locally so your data is never uploaded or stored.
