Tool Guide

Tool Introduction

The Online ID Card Number Age Batch Calculation and Statistics Tool supports batch parsing of ID card numbers and automatically calculating age, birth year, generational distribution, and other information. It is suitable for HR statistics, user analysis, data cleaning, and other scenarios.

The tool first performs basic validity checks on ID card numbers, then extracts birthday information for age calculation, and outputs three types of results: "statistics by decade, statistics by age, and detailed list," supporting one-click export to Excel.

For corporate HR, operations, and data personnel, it can quickly complete employee age structure analysis, user profile stratification, and abnormal number screening, improving data processing efficiency.

Frequently Asked Questions (FAQ)

Does it support 15-digit ID card numbers?

The current tool mainly performs validity checks and age statistics based on 18-digit ID card numbers; we recommend using 18-digit numbers preferentially.

Why do some numbers show an age of "-"?

This is usually because the number is invalid or the birthday digits don't conform to the rules; the system retains the original number and flags it as invalid for easy subsequent troubleshooting.

Will the data be uploaded to a server?

The tool mainly performs instant page-side calculation and is not used to store personal privacy data. Please do not submit sensitive information unrelated to your business.
