ID Card Number Attribution Query

Tool Introduction

This "ID Card Number Attribution Query [Real-time]" online tool aims to provide users with a fast and convenient ID card number attribution query service. Users only need to enter a valid ID card number, and the system will real-time parse its first six administrative division codes and display the province and city attribution information corresponding to the ID card number, including the attribution code and detailed administrative division name. Whether you need to verify information or understand the regional source, this tool can provide instant and accurate query results.

Structure and Meaning of ID Card Numbers

Chinese resident ID card numbers consist of 18 or 15 digits, and their structure contains rich geographical and personal information. Among them, the most crucial are the first 6 digits, which are called administrative division codes, directly corresponding to the provincial, municipal, district/county-level administrative division codes of the cardholder's household registration. Through these 6 codes, this tool can parse the precise attribution of the ID card number, helping users quickly identify the regional source of the ID card. For example, the first two digits represent the province, the third and fourth digits represent the city, and the fifth and sixth digits represent the district/county. The subsequent 8 digits are the date of birth code, the second and third to last digits are the sequence code, and the last digit is the checksum.
