Recycled Phone Number Checker

Recycled Phone Number Checker: Core Features and Principles

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.

Frequently Asked Questions (FAQ)

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.

Important Notes

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.

Technical Notes & Usage Suggestions

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".
