What is the screening system? What pain points does it solve in acquiring customers overseas?

Screen number system, to put it simply, is a tool that batches detects whether mobile phone numbers are registered, active, and have specific attributes (such as gender, age) on a certain social platform. It usually works in the way of “number → platform → test results”: upload a batch of numbers, the system automatically determines which numbers are available on the platform, and returns detailed fields.

For the overseas marketing team, the unscreened number library is like a barrel of raw materials with unknown ingredients:

• Invalid Reach: Sending messages to numbers that are not registered with Telegram is a waste of message quota.
• Account Banning Risk: Repeated mass messaging to inactive or low-activity numbers can easily be judged as harassment by the platform, resulting in the account being banned.
• Population mismatch: It needs male users but sends it to females, or it needs users around 30 years old but doesn’t distinguish between them. The conversion rate is extremely low.

The core value of Screen Number System is:

1. Reduce ineffective costs: Only market effective and active numbers, and every penny is spent wisely.
2. Improve accuracy: Narrow the target group through gender, age, active window and other dimensions to achieve targeted reach.
3. Protect Account Health: Avoid frequent sending to “dead accounts” or “zombie accounts” to reduce the probability of account closure.

What social platforms does the screening system support? What are the detection dimensions?

The current mainstream screening system covers the most commonly used social platforms for overseas business:

Platform	Common detection dimensions	Data value
Telegram	Open, active, gender, age, avatar, tgid	Suitable for community operation, private message promotion, adding followers
WhatsApp	Open, active, gender	Suitable for business communication and customer follow-up
Line	Open, valid, gender, uid	Japan, Taiwan, Thailand market
Zalo	Open, active, gender	Vietnam, Southeast Asia market
iMessage / iOS	Blue ID detection, iMessage availability	Reaching high-value iOS users
Viber	Open and active	Eastern Europe and Middle East markets
Facebook / Instagram	Open (some platforms)	Social advertising assisted verification
Binance, LinkedIn	Activation (specific scenarios)	Cryptocurrency/Business Group

Note: The detection fields of each platform are based on the actual column names when exported by the console. The specific fields supported by different filter systems may be slightly different.

What data can be obtained by Telegram filter number?

Telegram is one of the most frequently used platforms for overseas marketing. Through the Screen Number System, you can get the following fields:

• tg activation: Whether the number has been registered with Telegram.
• tg active: the last online time (the active window can be set, such as “active in the last 7 days”).
• tg gender detection: includes gender field, and age field. It should be noted that the age data is based on Telegram public information or model estimation, and can be used to screen people “about 30 years old”, but it does not have the accuracy of ID cards.
• tgid export: You can directly obtain the user’s tgid to facilitate subsequent targeted messaging through the API.

This data allows the marketing team to easily filter out segments such as “male users active in the last 30 days” or “female users aged 25 to 35 years old.”

What is the difference between WhatsApp and Line screens?

Although WhatsApp and Line are both instant messaging tools, there are significant differences in screening scenarios:

• WhatsApp: More focused on Active/Active/Gender. WhatsApp’s activity detection is usually based on last online time (visibility), while gender identification relies on public information or header analysis. Suitable for universal number verification in global markets.
• Line: In addition to being activated and active, the Line screen number can also output uid (user’s unique identifier) ​​and gender. Line uid can be used for targeted push (such as Line@ or Line Bot messages), which is particularly important in markets such as Japan and Taiwan. Additionally, Line’s age field is relatively scarce, and the actual value is subject to console export.

Generally speaking, WhatsApp is suitable for wide-spread verification, and Line is suitable for refined operations (especially in the Japanese market). The two can be used together to complement each other.

What is the billing model of the screening system? How are costs estimated?

Screen number system generally adopts the model of per-item deduction and no subscription package. You don’t need monthly or annual fees, you just need to recharge your balance first, and then the corresponding fee will be deducted every time a number is detected.

Key Features:

• Per-item deduction: Different platforms and different detection types (activated vs. active vs. gender) have different unit prices. Please see the real-time price on the console for the specific unit price**.
• Task Preview Cost: Before submitting the selected task, the system will display the estimated cost and confirm it before execution.
• Insufficient balance: If the balance is insufficient to pay for the entire batch of tasks, it cannot be submitted and needs to be recharged first.
• Recharge method: The current mainstream solution supports USDT (TRC20) recharge, with a minimum of about 50 USDT, and the balance will be automatically updated after arrival.

How to estimate costs?

Suppose you need to screen 100,000 numbers, 50,000 for Telegram activity detection and 50,000 for WhatsApp activation detection. Then check the console first: the unit price of Telegram activity detection is X yuan/item, and the unit price of WhatsApp activation detection is Y yuan/item. The total estimated cost (50000×X + 50000×Y) will be displayed before the task is completed. Since there is no monthly fee, this model is very suitable for small and medium-sized teams and occasional batch screening scenarios.

How to choose a screening system suitable for overseas teams? key assessment dimensions

The screening systems on the market have different functions. The following dimensions can help you make a reasonable choice:

• Platform Coverage: Are the major platforms in your target market supported? Such as Telegram, WhatsApp, Line, Zalo, iMessage, etc.
• Data Accuracy: How accurate is the activation/active/gender detection? You can test and compare in small batches first.
• Export format: Supports common formats such as CSV and TXT to facilitate downstream batch processing.
• Task Notification: Will you be notified via Telegram when completed? Avoid refreshing the background all the time.
• Data Deduplication: Is there a built-in deduplication function? Avoid wasting balance through repeated testing.
• Deposit method: Does it support USDT? How flexible is the recharge?
• Customer Service Response: Are there official robot and manual customer service channels?

Natural mention: KK-DATA has mature solutions in the above dimensions, especially supporting two-way customer service contact (https://t.me/kkdata_robot) and built-in data deduplication warehouse.

Why is data deduplication important?

In multiple number screening tasks, the same number may be uploaded repeatedly. If there is no deduplication mechanism, the system will detect the number repeatedly and charge fees repeatedly. Data Deduplication Warehouse will automatically compare the historical data before you submit the task, eliminate the numbers that have been detected, and only filter the new numbers. This can save 30% to 50% of costs, which is especially suitable for continuous customer acquisition teams.

How to get the results after the screening task is completed?

After the task is completed, there are usually two ways to obtain the results:

• Online Export: Select CSV or TXT format download in the console.
• Notification Push: Configure Telegram notifications to automatically send messages after task completion, including a summary of results and a download link.

Some systems (such as KK-DATA) also support pushing results directly to designated API interfaces to realize automated pipelines.

Practical application of screening system in acquiring customers on Telegram and WhatsApp

The following scenarios can directly connect to your marketing process:

Scenario 1: Verify whether the vertical user number has activated Telegram

You have a batch of customer mobile phone numbers collected from exhibitions and hope to promote products through Telegram private messages. Direct mass messaging may result in a large number of failed receipts. Use the Filter Number System → Select “Telegram Activation Detection” → Upload numbers → Filter out the numbers that have opened Telegram → Then send messages to these numbers. In this way, the message success rate can be increased from 20% to more than 90%.

Scenario 2: Screen the numbers that are active in the month and have a male gender for private message promotion

For high-priced products for male users (such as cross-border tools, training courses), you can check “Telegram active (last 30 days)” and “Gender: Male” in the screening task, and the results returned by the system will be the precise target group. You can also use the age field to further filter the group between 28 and 35 years old.

Scenario 3: Identify invalid numbers to avoid invalid group additions

When doing Telegram group fission, inviting invalid numbers will occupy the group request limit and affect group activity. First use the filtering system to filter out unactivated or low-active numbers, and only invite high-quality numbers to the group.

Common misunderstandings and pitfall avoidance guides in the screening system

Misunderstanding 1: Thinking that the screening results are 100% accurate

No system can be 100% accurate. Activity detection is based on recent online time, which may vary by several hours; gender detection is based on public information, and some users’ privacy settings are not public and cannot be determined. Recommended as a reference indicator, not an absolute standard.

Misunderstanding 2: The lower the price, the better

Low price may mean fewer detection nodes, slow data updates, or even the use of false results. The cost-effectiveness should be comprehensively evaluated in combination with “accuracy rate + platform coverage + export fields”.

Misunderstanding 3: Believe in “free forever”

No sustainable screening service can be free forever. So-called free versions often have limited quantities, high latency, and poor data quality. Billing by item is a common practice in the industry, and it is more reasonable to pay what you use.

How to avoid pitfalls?

Common pitfalls	Correct practices
Encountered the so-called “unlimited free” screening system	Test in small batches first and compare the results
Customer service requires transfer to third-party chat software	Contact through official channels (such as official robots, official website)
The remaining balance cannot be refunded after recharging	Choose the per-item deduction model to avoid pre-purchasing packages
Claims to be able to detect “accurate age on ID card”	Understand that age data is based on estimation and should not be overly relied upon

Are gender and age data accurate to the ID card level?

**Not precise. ** Age data is usually based on Telegram’s public information (such as birthday fields) or model predictions. It can be used for crowd profiling (for example, “most users are between 25 and 35 years old”), but cannot be used as the only basis for identity verification. Similarly, gender detection also has a certain error rate. It is recommended to make a comprehensive judgment based on multiple dimensions (such as avatar, nickname).

Are all country numbers supported?

Screen number system typically supports the generation and detection of 240+ country numbers worldwide. But please note: Screen number results are affected by local user registration behavior. For example, in a country with low penetration rate, the majority of Telegram activation test results may be “not activated”. For niche countries, some fields (such as gender) may be missing due to insufficient coverage.
