Still annoyed by spam calls? The recycled phone number checker can detect whether an 11-digit number has been recycled and reissued by the carrier. Number recycling refers to carriers putting deactivated phone numbers back on the market. By entering a phone number and a pre-verification date, this tool returns the status description, carrier information (China Mobile/China Telecom/China Unicom), and risk warnings, helping you avoid spam and registration conflicts left by the previous owner.
How do I check the recycled status of a phone number?
Simply enter the 11-digit phone number and an 8-digit date (yyyyMMdd format) to check.
Does the pre-verification date affect the test results?
Yes. This date is used to simulate the status of the number at a specific point in time. If it exceeds the carrier's cooling-off period (usually 6 months), it may show a "Ready for Release" status.
The phone number must be 11 digits; the date must be in an 8-digit numeric format (e.g., 20250101). Results are for reference only. For dynamic number statuses, please refer to real-time carrier data. Do not use this tool for illegal purposes. For sensitive information queries, we recommend verifying through official channels.
Enterprise users are advised to integrate the API endpoint (path: /verify/mobile_twice_check) to batch verify registration numbers. Typical scenario: Entering 18800001234 + 20250101 might return "Recycled Number Risk | China Mobile | This number was canceled in 2024".
