- A: This tool supports identifying and extracting both 18-digit (new version) and 15-digit (old version) Chinese mainland citizen ID card numbers.
- Q: Can I process text containing a large number of ID card numbers at once?
- A: Yes, you can paste text containing a large amount of content into the input box at once, and the tool will automatically iterate through and extract all ID card numbers that conform to the rules.
