ID Card Parser

This is a free, efficient browser-based utility designed to analyze 18-digit Chinese Resident Identity Card numbers. It instantly decodes hidden information such as the province, city, district, date of birth, gender, and zodiac signs without any software installation. It is optimized for HR professionals, developers, and individuals needing to verify ID formats or calculate age quickly.

Yes, your privacy is fully protected. This tool operates entirely on 'Client-Side' technology using JavaScript within your browser. The ID numbers you enter or generate are processed locally on your device and are never transmitted to our servers or stored in any database. You can use it with complete confidence.

No, it cannot. This tool strictly adheres to privacy laws and only parses the information encoded within the number logic itself (like region codes and birth dates) based on the GB 11643-1999 national standard. It does not connect to any police or government databases, so it cannot retrieve personal names, photos, or addresses.

The 18th digit of a Chinese ID card is a validation code calculated mathematically from the first 17 digits. If the calculator reports a checksum failure, it means the ID number contains a typo or is mathematically invalid. This feature helps prevent data entry errors in forms or systems.

The 18-digit number is structured as follows: digits 1-6 represent the administrative division code (location), digits 7-14 represent the date of birth (YYYYMMDD), digits 15-17 represent the sequence code (where the 17th digit indicates gender: odd for male, even for female), and the 18th digit is the validation checksum.

The Random button generates a mathematically valid, virtual ID number. This is particularly useful for software developers and testers who need sample data to test input forms, validation logic, or age calculation features in their applications without using real personal data.
