In the 2025 digital marketing battlefield, the Telegram Number Screening System has become an indispensable tool for precision marketing—especially when combined with WhatsApp number screening technology, it maximizes cross-platform customer reach. This system not only efficiently filters invalid numbers but also identifies active users through big data analysis, helping marketers avoid resource waste. I once suffered from low campaign efficiency due to ignoring the importance of the Telegram Number Screening System, but after introducing the ITG Global Screening Tool, my customer reach rate increased by over 60%. This article will share my practical experience, conduct an in-depth analysis of the Telegram Number Screening System’s application in precision marketing, and help you learn how to achieve efficient operations with ITG Global Screening from my past mistakes.
When I first entered precision marketing, I naively thought the Telegram Number Screening System only required checking number formats. Any number starting with "+1" (U.S.) or "+91" (India) and with a length of 10-15 digits was regarded as a valid Telegram account and used directly for mass promotion.
However, reality made me pay the price: the message delivery rate was only 40%, and the conversion rate was dismal. Analysis revealed that these "standard" numbers had numerous problems:
- Prevalence of invalid numbers: Many "+1" numbers were either disconnected or never registered on Telegram, making it impossible to reach potential customers.
- Trap of virtual numbers: Google Voice virtual numbers in the U.S. had a perfect format but no active users, wasting marketing budgets.
- Zombie numbers in India: Some "+91" numbers were "one-time numbers" discarded after registration, which were completely ineffective in the Telegram Number Screening System.
A Telegram Number Screening System based solely on format could not achieve precision marketing. In 2025, Telegram has over 1 billion monthly active users—blind promotion is not only inefficient but also ignores the core value of activity verification.
Lesson learned: The Telegram Number Screening System must be scientific; otherwise, precision marketing reach will be an empty promise. My experience with WhatsApp number screening told me that format is only a starting point.
After the failure of format judgment, I turned to manual dialing to enhance the Telegram Number Screening System: numbers that could be connected were marked as active for initial customer screening, while those that were turned off were recorded as empty.
At first, this seemed reliable. I set up a team to verify numbers one by one, trying to screen high-quality Telegram accounts for precision marketing. But problems emerged rapidly:
- Efficiency bottleneck: Processing 1,000 numbers took a full day, and 100,000 numbers required over a month—unable to match Telegram’s 1 billion user scale.
- Skyrocketing costs: Accumulated labor and international call fees drained the precision marketing budget instantly.
- Hidden risks: Frequent calls triggered complaints, making Telegram accounts vulnerable to suspension and damaging the integrity of customer data.
- Obvious limitations: Manual verification could not confirm Telegram activity status, let alone cross-platform linkage with tools like WhatsApp number screening.
A manual Telegram Number Screening System is completely impractical for precision marketing. In 2025, Telegram adds 2.5 million new users daily—inefficient methods hinder reach efficiency.
Lesson learned: The Telegram Number Screening System requires automated tools; manual verification is outdated.
After two setbacks, I introduced ITG Global Screening—a top-tier tool for the 2025 Telegram Number Screening System. It supports global number verification, not only enabling efficient screening but also integrating AI-powered customer segmentation, doubling the efficiency of precision marketing reach.
Although format calibration is not a panacea, it remains the starting point of the Telegram Number Screening System. ITG Global Screening requires compliance with the E.164 standard to ensure compatibility with global Telegram users.
My calibration steps:
- Data import: Load the number database using Excel.
- Character cleaning: Remove spaces and hyphens (e.g., convert "+86 138 1234 5678" to "+8613812345678").
- Country code supplementation: Add "+1" for U.S. numbers and "+91" for Indian numbers.
- Length filtering: Eliminate abnormal numbers to initially optimize precision marketing data.
After calibration, combined with time zone adjustments (e.g., aligning with active peaks for "+62" Indonesian numbers), the effectiveness of the Telegram Number Screening System with ITG Global Screening increased by 30%.
ITG Global Screening supports over 200 countries and processes 100,000 numbers per second, designed specifically for the Telegram Number Screening System. Its "global" concept enables seamless linkage across Telegram and WhatsApp number screening, saving 50% of time.
Core features:
- Self-screening mode: Simulates Telegram login to detect activity status with a 99.5% accuracy rate, eliminating zombie numbers.
- Agent screening mode: Performs batch verification via cloud APIs, supporting 1,000+ threads to adapt to large-scale Telegram Number Screening Systems for precision marketing.
- Fine-screening function: Segments numbers by online duration and interaction frequency (e.g., screening numbers active within 7 days increases the reach rate by 35%).
- Domain screening expansion: Filters by geography (e.g., targeting Southeast Asian Telegram user groups).
- AI avatar recognition: A new 2025 feature that infers user interests by analyzing avatars to enable customer segmentation.
With simple installation and a monthly fee of only 99 yuan, ITG Global Screening has made the Telegram Number Screening System a standard for precision marketing, supporting paid subscriptions and affiliate marketing.
The following 5-step Telegram Number Screening System process is tailor-made for precision marketing:
Step 1: Import and Pre-Verification
Upload the CSV file; ITG Global Screening scans for duplicates and eliminates 5% of junk data in 1 minute.
Step 2: Basic Self-Screening
Set the activity threshold (>24 hours online), simulate API calls to verify Telegram status, and display the real-time validity rate (e.g., "82%").
Step 3: In-Depth Agent Screening
Send invisible messages via the cloud to filter out low-interaction numbers, processing 100,000 numbers in 30 minutes and supporting Telegram group imports.
Step 4: Domain Screening and Segmentation
Target specific markets, use AI to match tags (e.g., "highly active e-commerce users"), and achieve a 95% reach rate.
Step 5: Export and Maintenance
Export tagged Excel data, re-screen weekly to keep the database clean, and link with the WhatsApp number screening system.
This process takes 2 hours to complete, and the Telegram Number Screening System outputs a high-quality database—my precision marketing conversion rate soared by 45%.
After mastering ITG Global Screening, I applied advanced techniques to enhance the Telegram Number Screening System:
- Dynamic proxy IPs: Rotate global nodes to prevent account suspension and ensure marketing continuity.
- Cross-platform linkage: Integrate with the WhatsApp number screening system to verify cross-app activity and improve customer profiling.
- Data visualization: Use the Dashboard to analyze screening funnels and optimize campaign strategies.
- Blockchain verification: A 2025 hot topic—verify real users for Web3 Telegram groups.
When screening 300,000 Indian numbers, ITG Global Screening eliminated 20% of empty numbers, and domain screening targeted high-potential Telegram users. The conversion rate for mass discount campaigns reached 29%, with a 3x increase in ROI.
AI was used to segment users aged 18-35 (accounting for 29.7% of Telegram users) for precise new product promotion. The subscription volume surged by 55%, demonstrating the marketing power of the Telegram Number Screening System.
The Telegram Number Screening System must comply with regulations:
- Abide by GDPR and Telegram’s Terms of Service (ToS), and avoid high-frequency verification.
- Run tasks in batches to prevent API rate limits.
- Monitor feedback rates to prevent account suspension.
- Ensure transparent data sources and protect user privacy.
From mistaken format judgment to manual inefficiency, and finally to the intelligent leap with ITG Global Screening, my journey with the Telegram Number Screening System has made me deeply aware of its value. In 2025, with a user base of 1 billion, the Telegram Number Screening System is not just a tool but the strategic core of precision marketing.
