ID Card Check
Validate & parse ID numbers
TL;DR Summary & Citation: [ID Card Check] is used to Validate & parse ID numbers. Core input and files are processed in the current browser and are not sent to the PocketKit API. The page records only an aggregate tool-use count that excludes input content.
How ID-card validation works
The tool checks the check digit of an 18-digit Chinese ID per the GB 11643 rule locally and parses the birth date, gender and region code. The number is not uploaded.
Usage Guidelines & Tips
- It only validates format and the check digit, not whether the number really exists or is registered.
- ID numbers are sensitive; the tool processes them locally, storing and uploading nothing.
Frequently Asked Questions
1. Does passing validation mean the ID is real?
No. The tool only checks the 18-digit check digit and format and parses birthplace and gender; it cannot confirm the number exists or is registered.
2. Is the number I enter uploaded?
No. Validation and parsing happen locally; the sensitive number never leaves your device.
