Mobile Number Re-issuance Query

Tool Introduction

The Mobile Number Re-issuance Query tool is an efficient and convenient online service designed to help users quickly identify whether a mobile number has been re-issued. By entering the mobile number you need to verify and the specified pre-verification date, this tool will provide you with a description of the number's current status and accurately identify its operator (China Mobile, China Telecom, China Unicom). Whether you are expanding your business, verifying user registrations, or simply want to understand the historical usage of a number, this tool can provide valuable reference information and effectively avoid potential problems caused by re-issuance.

Background and Impact of Mobile Number Re-issuance

"Mobile number re-issuance" refers to operators re-introducing mobile numbers that have been cancelled, suspended, or unused for a long time into the market for new users after a period of "cooling-off". This mechanism aims to efficiently utilize number resources but also brings some problems. For new users, they may receive spam calls and messages left by the previous owner, or even encounter situations where the number is already occupied when registering for various applications, leading to the inability to use services normally. For businesses and individuals, when conducting SMS marketing, APP registration verification, and other processes, if re-issuance detection is not performed, it may lead to incorrect information delivery, verification failure, and even risks such as privacy leakage. Therefore, performing a re-issuance query is of great significance for ensuring information security and improving business efficiency.

How to Use
