Number Screening Platform FAQ: 10 Common Questions Answered & Practical Guide (Telegram/WhatsApp Number Screening Tutorial)

Overseas customer acquisition relies on number screening, but many teams encounter a series of questions when using a number screening platform for the first time: What is a number screening platform? How do you check whether Telegram numbers are active? What’s the difference between WhatsApp number screening and Telegram number screening? Will per-number billing cause costs to spiral out of control? This article summarizes 10 common questions about number screening platforms and provides clear operational guidelines based on real-world scenarios like Telegram/WhatsApp screening, global number generation, data export, and deduplication. Whether you are running an independent site, managing a community, or working as a third-party operations team, this article will help you get started quickly and efficiently take the first step in customer acquisition.

What is a number screening platform? How is it different from ordinary number validation tools?

A number screening platform is an online service that batch-processes deep data such as validity, activity status, and gender for social accounts across multiple platforms. Taking KK-DATA as an example, it supports Telegram, WhatsApp, iMessage, RCS, and other platforms. A single task can process approximately 1 million numbers, and it offers advanced features like activity window selection, gender identification, and tgid/wsid export.

In contrast, ordinary number validation tools can usually only perform a simple “registration check”—determining whether a number is registered with a certain app. They cannot determine whether a user is active or export social IDs in bulk. In simple terms: ordinary validators are like a talking pen—they can only “read one and say one”; a number screening platform is like a scanner—it scans an entire box of books at once and tells you which pages have been turned.

How to use a number screening platform to check whether Telegram numbers are valid and active?

Telegram screening is the most common scenario for overseas customer acquisition. The operation process is divided into four steps:

1. Select the detection type: In the console (e.g., https://app.kkdata.cc/ ), create a new task and select “Telegram Screening.” You will see three core options:
   • tg registered: Verifies whether the number has registered for Telegram.
   • tg valid: On top of registration, excludes accounts that have recently been deleted or restricted.
   • tg active: Checks whether the number has had any active behavior (sending messages, opening the app, etc.) within a specified time window.
2. Configure the activity window: Choose 7 days, 15 days, or 30 days based on your promotion rhythm. A shorter window yields more proactive users but fewer in number; a longer window covers a broader audience but may reduce activity quality.
3. Submit the task: Upload a CSV/TXT file containing phone numbers (one number per line, international format like +8613800138000). The system will display an estimated cost. Confirm and submit.
4. Export results: After the task is completed, download the filtered results from the console. The CSV file will include each number’s detection status, activity level, gender (if supported), tgid, and other information.

How to choose the activity window (7/15/30 days)?

• 7-day window: Suitable for short, quick promotional activities like limited-time offers, flash sales, or meeting invitations. You want to reach users who have been active in the past week, ensuring a high immediate response rate.
• 15-day window: A balanced choice. Suitable for daily product pushes or community recruitment, maintaining a decent activity level while keeping a larger quantity.
• 30-day window: Suitable for the cold-start phase of long-term conversion, such as brand awareness building or content seeding. First cover all registered users, then use subsequent interactions to screen high-potential leads.

Recommendation: If your budget allows, first run a 30-day window to screen all registered users. Then, target the 7-day active users for the first round of marketing, and put the remaining users into a nurturing process.

What is the benefit of exporting tgid? How does it help community management?

tgid is the unique numeric identifier assigned to each user by Telegram. Its practical uses are:

• Bypass number segment restrictions: Initiate conversations or invite users to groups directly via tgid, which is more stable than using phone numbers and less likely to trigger system limits.
• CRM integration: Link tgid with customer behavior data for easier tagging, grouping, and attribution analysis.
• Batch operations: Use automation scripts to batch-send messages or add users to groups based on a tgid list, improving operational efficiency.

When screening WhatsApp numbers, which detection types should you focus on?

The core of WhatsApp screening is confirming whether a number is registered with WhatsApp (i.e., “valid number detection”), and you can export wsid—the equivalent of WhatsApp’s user ID. Unlike Telegram, WhatsApp currently does not provide native activity detection or gender identification. Therefore, when using WhatsApp screening, focus on these two points:

• Valid number detection: Filter out invalid numbers and unregistered numbers, keeping only real users who actually use WhatsApp. This is the foundation for precise targeting.
• wsid export: Similar to tgid, wsid can be used for subsequent automated message pushes (e.g., via WhatsApp Business API), reducing delivery failures caused by number changes.

Additionally, if you also operate iMessage or RCS services, KK-DATA supports detection for these platforms. You can mix different detection types in the same task, but note that prices vary by platform—check the estimated cost before submitting.

The screening platform charges per number—how to control testing costs?

KK-DATA uses a no-subscription, pay-per-number model: you top up your balance first, and after the task is completed, the corresponding fee is deducted from the balance—pay only for what you use. This model is friendly to both small teams and large-scale needs, but beginners often overlook a few cost control tips.

How to estimate the cost before submitting a task?

When creating a new screening task in the console, after selecting the platform and detection type, the system will automatically display the estimated cost based on the number of uploaded numbers. If your balance is insufficient, the task cannot be submitted, and the system will prompt “Insufficient balance. Please top up first.”

Recommendation: Before uploading numbers each time, perform batch deduplication (using the data deduplication warehouse or preprocessing yourself) to avoid wasting money on checking duplicate numbers.

How much money can the data deduplication warehouse save you?

The data deduplication warehouse is a built-in “historical cache” feature of KK-DATA. When you submit a new task, the system automatically compares the numbers against previously checked ones. Numbers that have already been checked will not be charged again. This is especially useful for scenarios where you frequently clean the same customer list or perform incremental checks in batches.

Long-term use of the data deduplication warehouse can save 30%–50% of screening costs, depending on the data overlap rate.

Is global number generation free? How to quickly screen generated numbers?

Global number generation is completely free. KK-DATA supports three generation methods:

• Random generation: Select a country (240+ countries/regions), enter a quantity, and the system randomly generates numbers conforming to international format.
• Prefix generation: Enter the first few digits of a country’s number prefix (e.g., US +1301), and the system generates consecutive numbers under that prefix.
• Custom CSV import: Upload your own list of number prefixes, and the system parses and generates corresponding numbers.

Generated numbers can be submitted directly for screening with one click in the console, forming an end-to-end pipeline: generate → screen → export. However, note that while generation is free, screening still charges per number. It is recommended to first generate numbers for your target country, then run a Telegram/WhatsApp validity check to filter them, and finally perform an activity check on the valid numbers—this maximizes your budget.

What export formats are supported for screening results? How to handle subsequent data?

After screening is complete, results can be exported in CSV and TXT formats. CSV contains detailed fields (number, detection status, activity level, gender, tgid/wsid, etc.) and is suitable for importing into CRM systems, email marketing platforms, or Excel for secondary analysis. TXT usually contains only a list of numbers, suitable for direct use in batch messaging tools.

After export, you can:

• Import active numbers into Telegram or WhatsApp automation tools to start the first round of outreach.
• Segment users by gender or activity level and design differentiated messaging for different groups.
• Link exported tgid/wsid to your internal CRM to build user profiles and track conversions over time.

Frequently Asked Questions

Q: How accurate is the activity detection on the screening platform?
A: Activity detection is based on public social platform features, such as Telegram’s “Last Seen” time or channel interaction records. Accuracy is typically between 85%–95% (affected by platform data rules). It is recommended to use activity as a screening reference rather than an absolute judgment, and further validate through actual test sends.

Q: Can the same number be checked multiple times? Will I be charged repeatedly?
A: If you use KK-DATA’s data deduplication warehouse, the same number under the same detection type will only be charged once. However, if you switch detection types (e.g., first check “registered” and later check “active”), each type will be billed separately because they are different tasks.

Q: When generating numbers, will the system generate numbers that belong to real users?
A: Randomly generated numbers comply with international number rules but are likely unregistered/inactive numbers. They are mainly used for “dictionary-style” screening—testing to identify which are real registered users. Please comply with local laws and do not use them for harassment or illegal purposes.

Q: Can I use the screening platform to check other platforms (e.g., Facebook, Instagram)?
A: Currently, KK-DATA mainly supports four platforms: Telegram, WhatsApp, iMessage, and RCS. If you need detection capabilities for other platforms, please monitor official updates or contact customer support.

Q: What is the minimum top-up amount? Are there any packages?
A: The minimum top-up is approximately 50 USDT (TRC20). There is no subscription package; charges are per number, pay-as-you-go. Topped-up balances are valid indefinitely. For details, check the billing page (https://kkdata.cc/billing/).
