What Is Chinese ID Lookup?

Chinese ID Lookup is a simple, fast online tool that verifies and decodes the information embedded in Chinese identity numbers. It supports Mainland China Resident Identity Cards, as well as Hong Kong, Macau, and Taiwan Resident Permit numbers. Each valid ID number contains location codes, date of birth, gender, and a checksum. By running a quick lookup, you can confirm whether a number is structurally valid and extract basic demographic data without needing to access any private databases.

This tool is especially useful for businesses, HR professionals, and service platforms that need to validate identity numbers provided during registration or verification. Instead of manually checking the format or relying on slow, unreliable methods, Chinese ID Lookup gives you an instant result with clear, accurate information. It respects privacy by only processing the number’s logic structure and never storing or sharing any personal data.

Key Features

  • Instant validation – Enter a Chinese ID, Hong Kong, Macau, or Taiwan permit number and get results in seconds.
  • Detailed breakdown – Displays province, city, district of origin, birth date, gender, and checksum status.
  • Supports four region types – Covers Mainland China (18-digit), Hong Kong, Macau Permanent Resident, and Taiwan Resident Permit formats.
  • No registration required – Use the tool freely without creating an account or logging in.
  • Privacy-safe – All processing happens in-browser; no data is sent to or stored on any server.

Frequently Asked Questions

Is this tool free to use?

Yes, the Chinese ID Lookup tool is completely free. There are no hidden fees, no usage limits, and you do not need to create an account. Simply enter a number and get instant validation results.

Does it look up real personal information like names or addresses?

No. The tool only extracts data that is mathematically embedded in the ID number itself – such as administrative region codes, birth date, and gender. It cannot reveal names, addresses, or other private details. The lookup is purely based on the number’s structure and public code tables.

Why does my Hong Kong resident permit number show as invalid?

Hong Kong permit numbers follow a specific format that may include brackets and letters. Make sure you enter the complete code (e.g., ABC123456(7)). The tool expects the standard format without spaces. If the number is correct but still flagged, it may be an older or non-standard issue.

Can I use this tool for Macau resident permits?

Yes. The tool supports Macau Permanent Resident Identity Card numbers. These usually start with a letter followed by digits. Enter them exactly as shown on the card (including any parentheses). The validation logic checks the checksum and length.

How accurate is the gender and birth date information?

The birth date and gender are derived directly from the ID number structure. In Mainland China IDs, digits 7–14 encode the birth date in YYYYMMDD format, and the second‑last digit indicates gender (odd = male, even = female). These decodes are 100% accurate when the number is structurally valid.

What should I do if the tool shows “Invalid checksum”?

An invalid checksum means the number failed the weighted modulus verification. This could be due to a typo, an outdated number, or a fraudulent entry. Double‑check the digits you entered. If the number is from an older 15‑digit format (pre-1999), this tool supports only the current 18‑digit standard.
