When enterprises need to send mass SMS to customers or conduct precision marketing, the difference in tariffs among different carriers can cause significant cost waste. By analyzing the characteristics of 11-digit mainland China mobile numbers, this tool bulk identifies whether a number has completed Mobile Number Portability (MNP) and tags its current actual carrier (China Mobile/China Unicom/China Telecom). A single query eliminates the tedious traditional process of visiting carrier websites one by one.
How do I know if a number has been ported?
If the result shows "Ported," it means the number's current carrier does not match its original prefix.
How is the timeliness of bulk queries guaranteed?
The data update frequency is T+1 days. For highly time-sensitive operations, we recommend secondary verification through official carrier APIs.
Only supports valid 11-digit mainland China mobile numbers. Results do not contain user privacy information. For queries exceeding 3,000 numbers at once, we recommend processing them in batches.
Typical use case: An e-commerce company needs to send promotional SMS to 100,000 members. By using this tool to filter out all numbers "Ported to China Telecom" and routing them through a dedicated Telecom channel, communication costs can be reduced by 15-20%. Example input: 13912345678, 13012345678; Output: 13912345678 Not Ported China Mobile | 13012345678 Ported China Telecom.
