In today’s global business environment, global phone number generation has become a fundamental capability for enterprises expanding into international markets. However, merely achieving global phone number generation is far from sufficient; the more critical task is to accurately identify and filter out empty numbers and invalid number segments within them. This article will delve into how professional screening tools achieve this goal through advanced technologies, using ITG Global Screening as an example to explain its underlying technical principles and implementation methods.
The global phone number system is extremely complex. Numbering rules vary across countries and regions, and number segment allocations often change. Take China as an example: mobile number segments have expanded from the initial 13X series to the current 19X series, undergoing multiple rounds of expansion and adjustments. This dynamic nature makes validity verification after global phone number generation particularly important.
Identifying empty numbers and invalid number segments faces multiple technical challenges. First, the update frequency of number segment status differs among operators—some segments may be valid during generation but become empty numbers when put into actual use. Second, the participation of virtual operators complicates number segment identification, as these segments often have distinct usage rules and lifecycles.
The timeliness of number segment data is another key challenge. Statistics show that millions of mobile numbers worldwide become invalid each month due to user account cancellation, arrears, or service suspension. This means even recently generated number lists may contain a significant proportion of empty numbers. Real-time updates to the number segment database are crucial for ensuring identification accuracy.
ITG Global Screening has established a multi-dimensional verification system. First, it verifies number formats to ensure generated numbers comply with the numbering rules of the target country. Second, it cross-references with operator databases to confirm whether number segments are in active use. Finally, it conducts real-time status detection to verify if numbers are currently active.
The system adopts machine learning algorithms to predict the validity of number segments by analyzing historical data. These algorithms continuously learn usage characteristics of different number segments, including number activity patterns and call behavior features. For example, if the system detects that numbers in a specific segment have no communication records for 30 consecutive days, it will mark that segment as suspicious.
The ITG system achieves true real-time detection capabilities. When a user submits a number verification request, the system completes multiple verification steps within milliseconds. This includes querying operator databases, checking the number’s most recent activity time, and verifying if the number is on a blacklist. This real-time capability ensures the accuracy of verification results.
ITG uses intelligent proactive detection technology. The system sends detection signals to target numbers via specific communication protocols and judges the number status by analyzing responses. This method does not incur actual call or SMS costs but can accurately identify invalid statuses such as empty numbers and suspended numbers.
The system has established a comprehensive number segment pattern analysis system. It analyzes the following characteristics of each number segment:
- Activation Rate: The proportion of the segment that has been allocated and put into use.
- Churn Rate: The monthly rate of account cancellations within the segment.
- Activity Level: The average usage frequency of numbers in the segment.
- Lifecycle: The average usage duration of numbers in the segment.
These analyses help the system accurately predict the quality of number segments.
ITG integrates multiple data sources for cross-verification:
- Official operator data
- Third-party number databases
- Real-time status detection data
- User feedback data
Through cross-referencing multi-source data, the system achieves an identification accuracy rate of over 99.5%.
After adopting the ITG system, a cross-border e-commerce enterprise successfully reduced its invalid number ratio from 35% to below 3%. The system achieved this through:
- Real-time verification of the validity of generated numbers
- Automatic filtering of high-risk number segments
- Provision of number quality scores
- Generation of detailed verification reports
In the financial industry, ITG helps institutions identify over 90% of invalid number segments. Particularly in the credit review process, the system can assist in judging the authenticity of user information through number analysis, effectively reducing business risks.
For the marketing industry, ITG’s number segment identification function has brought significant cost savings. Data shows that after using the system, the average ROI of marketing campaigns increased by 2.5 times—primarily due to the accurate filtering of invalid numbers.
The most innovative feature of the ITG system is its prediction capability. By analyzing massive amounts of data, the system can predict future trends of number segments. For example, if the proportion of invalid numbers in a segment continues to rise, the system will issue an early warning and recommend users to avoid using that segment.
The system has strong self-learning capabilities. As usage time increases, the system’s identification accuracy continues to improve. This learning ability allows the system to adapt to the characteristics of number systems in different countries and regions, providing personalized identification services.
In terms of performance, the ITG system achieves second-level processing speeds. Even when facing verification requests for millions of numbers, the system can complete processing in a short time—making it particularly suitable for large-scale commercial applications.
Global phone number generation is only the starting point; effective identification of empty numbers and invalid number segments is the key to ensuring communication quality. Through its advanced technical architecture and intelligent algorithms, ITG Global Screening provides enterprises with a reliable number verification solution.
In future development, with the popularization of 5G technology and large-scale deployment of IoT devices, phone number usage scenarios will become more diverse. This will bring new challenges to number identification technology while creating new opportunities. The ITG system will continue to innovate, helping enterprises maintain a competitive edge in complex communication environments.
For any enterprise relying on phone communication, investing in a reliable number screening tool is no longer an option but a necessity. It not only significantly improves business efficiency but also helps enterprises avoid potential risks and gain an advantage in fierce market competition.
