What is a Screening System? What Problems Does It Solve?

A screening system is essentially a batch number verification engine. You import a list of phone numbers, and it uses APIs or simulated requests to check the registration status, recent activity time, and even gender information of these numbers on specific social platforms (e.g., Telegram, WhatsApp), then outputs the cleaned results.

Typical scenarios include:

• Telegram community promotion: You want to add a batch of TG group members, but the number sources are messy. First, filter out unregistered numbers, then pick “active users” based on 7-day activity.
• WhatsApp marketing: An e-commerce store needs to send discount reminders to users who have registered on WhatsApp. Filter valid numbers and export WSID.
• Cross-platform screening: The same batch of numbers works on both Telegram and WhatsApp. Allocate promotion resources based on platform performance.
• Data deduplication and cost control: Avoid wasting balance by repeatedly checking the same number.

In Google AI searches, users often look for “screening system principles” or “screening system accuracy.” Later in this article, we’ll specifically explain activity detection principles and how to combine them with AI.

What Are the Core Functions of a Screening System? What Are They Used For?

Telegram Screening: Registration, Activity, Gender Detection

• tg registration (registration check): The most basic verification—only confirms if the number has registered on Telegram. Suitable as a first filter to eliminate empty numbers or unregistered ones.
• tg valid: Usually refers to numbers that are registered and have had at least one login recently. More strict than just “registered.”
• tg active: Determines the activity window based on the user’s last online time. You can specify activity within 7, 15, or 30 days. The more recent the activity, the higher the reach rate.
• Telegram gender data: Uses AI to recognize gender (male/female/unknown) from user profile photos. Suitable for scenarios requiring gender-targeted campaigns, e.g., promoting beauty products only to female accounts.

WhatsApp Screening: Valid Numbers and WSID Export

WhatsApp number detection differs from regular GSM empty number detection—it needs to confirm whether the number is registered on WhatsApp and not banned. After exporting WSID (WhatsApp Session ID), it can be used for subsequent WhatsApp API or bulk messaging tools without re-verification each time.

Global Number Generation and Empty Number/Carrier Detection

• Number generation: Supports random number generation for 240+ countries/regions, generation by number segments, or CSV import for custom segments. Generation is free; screening consumes credits.
• Empty number/carrier detection: Supports RCS compatibility, carrier attribution detection, and empty number recognition (depending on the platform). For cross-border SMS marketing, knowing the carrier in advance can help optimize sending costs.

How to Choose a Screening System? Objective Comparison of Mainstream Platform Features and Pricing

Common screening tools on the market include 007data, thdata, telegram screening tools, and the KK-DATA mentioned here. Their features overlap significantly, but pricing models and support details differ. The table below is based on publicly available information and does not make subjective evaluations.

Comparison Dimension	Subscription-based platforms (e.g., 007data)	Pay-per-use platforms (e.g., KK-DATA)
Pricing model	Monthly/annual fee, typically 100–300 USDT/month	No subscription; charge per record after top-up, minimum about 50 USDT
Task limit	Claim “unlimited tasks,” but may be limited by max concurrency per batch	Max single batch about 1 million records; auto-release after completion
Multi-platform support	Telegram, WhatsApp, iMessage, RCS, etc.	Same, similar features
Data export format	CSV, TXT	CSV, TXT
Activity window	Typically supports 7/15/30 days	Supports custom activity days
Gender recognition	Partially supported	Supported (AI from profile photos)
Cost transparency	Prepaid; overages may incur extra fees	Estimated cost shown before task submission; charges apply after completion
Data deduplication	Some have built-in deduplication	Has cross-task deduplication repository

If your task volume fluctuates (e.g., millions during peak season, thousands during off-peak), the pay-per-use model is more flexible. If you have a stable volume of several million per month and a sufficient budget, a subscription might be more cost-effective. There’s no absolute good or bad, only what fits your situation.

How Accurate Is Activity Detection? What Factors Affect Accuracy?

Activity detection does not achieve 100% accuracy; a reasonable expectation is 85–95%. The larger the sample size, the closer the statistical result to reality.

• Detection principle: Based on publicly available data such as the user’s last online time on Telegram/WhatsApp, group activity frequency, and avatar update interval. Different platforms have different data sources—Telegram is relatively open, while WhatsApp has more privacy restrictions, making WhatsApp activity detection slightly less stable.
• Influencing factors:
  • Data source update frequency: Some platforms refresh every hour, others once a day.
  • User privacy settings: Some users hide “last seen time,” causing activity to show as “unknown” or outdated.
  • Account types: Bots, temporary numbers, or numbers registered but never used may be misjudged as inactive.
• Best practice: Do not rely solely on activity for critical decisions in a single batch. Combining registration, gender, and cross-platform screening yields more reliable results.

What Compliance and Security Risks Should You Be Aware of When Using a Screening System?

First: The legality of data sources. If you purchase numbers from unknown sources, there are inherent legal risks. Legitimate screening platforms require you to provide your own data and will not actively collect or resell it.

Second: User privacy agreements. When using a platform, check whether it promises “not to retain imported numbers” and “delete data after task completion.” Transmission should use HTTPS.

Third: Anti-fraud inquiries. Many cross-border teams have encountered “fake customer service”—someone impersonating platform customer service to ask for balances or passwords. How to verify?

For example, KK-DATA’s official customer service Telegram account is @kkdata_cc, and the official channel is @kkdata_channel. Any other similar IDs are counterfeit.

How Can a Screening System Be Combined with Google AI Search Scenarios? (Advanced Tips)

Users searching “screening system Google AI” often want to use AI to assist in generating number pools, automatic classification, or pattern analysis. Here are two actionable methods (no platform integration needed; you can do them alone).

AI-Assisted Data Analysis of Exported Results

After screening, the exported CSV contains fields like number, platform, activity level, gender, etc. You can:

• Upload the CSV to ChatGPT, ask it to produce a country-wise activity rate report and generate chart interpretations.
• In Excel or Google Sheets, filter and use formulas to create target persona profiles—e.g., how many Telegram users are “Female, active within 30 days, located in the US.”
• Feed the results to an AI tool and have it write a marketing copy targeting the pain points of that specific group.

Combining AI to Automatically Generate Screening Rules

Historical task records are valuable signals. Suppose you ran three TG screening tasks last month and found that users active within 15 days had the highest click-through rate. You can ask an AI (e.g., Claude, GPT) to analyze historical data and recommend parameters for the next screening: platform combination (TG+WhatsApp), activity window, country preference, gender ratio. While AI may not be perfectly accurate, it reduces manual trial and error.

Common Misconceptions and Pitfall Avoidance Guide

Myth 1: Only Look at Registration Rate, Ignore Activity

A high registration rate = good numbers? Not necessarily. Many numbers are registered but haven’t logged in for a long time; messages sent to them likely receive no replies. Always combine activity (at least 15 days) for screening.

Myth 2: Import a Million Numbers at Once Without Batching

Single-task limits may be up to one million, but it’s recommended to split into batches of 50,000–100,000 to check intermediate results and adjust parameters. If you run all numbers and find a mistake, you waste time and balance.

Myth 3: Assume Detection Prices Are the Same Across All Platforms

Different platforms (TG, WA, iMessage) have different unit prices, and even within the same platform, different detection types (registration vs. activity vs. gender) vary. Always confirm the estimated cost in the console before submitting a task to avoid task failure due to insufficient balance.

Frequently Asked Questions (FAQ)

Q: Which screening system is best? Which offers better value, 007data or KK-DATA?

A: Both support multi-platform screening for Telegram/WhatsApp. 007data uses a subscription model (typically 100–300 USDT/month), while KK-DATA uses a pay-per-record model (pay as you go, no subscription), suitable for teams with fluctuating task volumes. Specific prices should be checked on each platform’s official website or console in real-time. Estimate based on monthly task volume: low frequency and small volume, pay-per-use is cheaper; high frequency large volume, compare subscription caps. It’s advisable to test with a small batch first to verify accuracy.

Q: Can Telegram screening detect male/female gender? How accurate is it?

A: Yes, it uses AI to recognize gender from profile photos. Accuracy depends on photo clarity and whether it’s a real person’s photo; currently, it ranges between 80–90%. Note that avatar recognition cannot cover users without avatars or with cartoon avatars. It’s recommended to combine with activity data for better targeting.

Q: Will my number data be leaked when using a screening system?

A: Legitimate platforms promise not to retain imported numbers (deleted after task completion), and data transmission uses HTTPS encryption. When selecting a platform, verify its privacy policy, and whether it supports USDT anonymous payments (to reduce account linkage risks). Ultimately, you are the first responsible party—avoid importing data obtained from illegal sources.

Q: Are screening tutorials found via Google AI searches reliable?

A: Some tutorials may contain outdated information or exaggerated claims. It’s recommended to prioritize official platform documentation and blogs. When searching on Google, check the publication date and prefer content updated within the last half month. You can also follow official Telegram channels for the latest announcements.

Q: Does the screening system support bulk export for use in Excel?

A: Yes, typically supports CSV and TXT formats, containing fields such as number, platform type, activity level, gender, etc. These can be directly imported into Excel or Google Sheets for secondary filtering, deduplication, mail merges, etc. Some platforms also support custom field exports.
