Concerned about the risks associated with newly registered phone numbers? Using carrier data interfaces, this tool allows you to input an 11-digit mobile number and returns its active duration range (e.g., 0-3 months or 24+ months). The phone number age refers to the continuous service time of the number on the carrier's network, which is a key metric for assessing user stability, anti-fraud, and credit evaluation.
Which regions are supported for phone number queries?
Currently, only 11-digit mainland China mobile numbers (e.g., 18888888888) are supported. Numbers from Hong Kong, Macau, Taiwan, and international regions are not supported at this time.
Why do the results show a range instead of specific days?
The carrier data interface returns standardized range values (e.g., 6-12 months), which are primarily influenced by data update cycles and number porting records. The accuracy margin of error is approximately ±15 days, making it suitable for preliminary risk control screening.
Please enter a valid mainland China mobile number (11 digits). Virtual carrier numbers may return "Unknown". Results are for reference only; sensitive business operations should be combined with multiple verifications. The system does not store query records, but please do not use this tool for illegal purposes.
For financial scenarios, it is recommended to use this in conjunction with real-name authentication. For new numbers showing "0-3 months", you may request additional proof of income. Typical query example: Entering 18800001111 might return "timeDesc: 24 months and above", indicating long-term stable usage of the number.
