Marketing campaigns often suffer from wasted costs and low conversion rates due to large volumes of invalid phone numbers. This tool uses real-time carrier interfaces to bulk check phone number statuses, accurately outputting results such as unassigned, disconnected, active, high-risk, or inactive. Phone number validation is the technical process of verifying whether a number actually exists and is available, effectively identifying invalid numbers to save on SMS and telemarketing costs.
Q: How accurate is the phone number validation?
A: The accuracy rate exceeds 98%. It is based on real-time carrier data, but since number statuses can change at any time, we recommend re-validating before critical marketing campaigns.
Q: Does it support virtual network operator (MVNO) numbers?
A: Yes. It can identify the status of virtual operator numbers, such as those in the 170 and 171 prefixes.
Please ensure that the input numbers are 11-digit numeric strings, and do not exceed 100,000 numbers per validation request. The validation results are for reference only, and we assume no liability for marketing losses caused by status changes. All uploaded data is immediately deleted after real-time processing to ensure your privacy and security.
We recommend validating your customer database on a monthly basis to prevent wasted marketing resources due to changing phone number statuses. Typical input: 13800138000 (Active), 13900000000 (Unassigned); Output: Clear status labels and brief descriptions, such as "Disconnected: User has suspended service." For inactive numbers, consider combining them with re-engagement strategies to maximize their value.
