Complete tutorial on active screening of US TG numbers: active window settings, usage order and list stratification

Among overseas customers, US tg numbers are a key target market for many marketing teams - the United States has a huge Telegram user base, highly active communities, and huge potential for private messaging. However, the list of directly collected or purchased numbers is often mixed with a large number of silent accounts that have been “opened but have not logged in for several months” and even contain invalid numbers. If you send messages blindly, not only will the response rate be low, but it may also trigger platform detection, resulting in account restrictions. At this time, “activity filtering” becomes the core technology to distinguish valid users from invalid numbers.

This tutorial will teach you step by step how to use the KK-DATA platform to accurately obtain highly active US Telegram numbers in the order of “Activate Detection → Active Detection → List Hierarchy”, and introduce the active window setting strategies and best practices. Whether you are doing B2B customer development, e-commerce promotions, or social media traffic, this method can greatly improve reach efficiency.

What is the “US TG Number” activity filter? Why is it important?

“Activity filtering” refers to further detecting whether the account has had any online behavior (such as sending messages, logging into the app) within the specified time window on the basis of confirming that the number has been registered in Telegram. TG users do not necessarily log in every day, and many accounts may be abandoned after being registered for only a few days. If you only do “activation testing”, you will still get a large number of “zombie accounts”.

Value of activity filtering:

• Improve private message reply rate: Users who have been online recently are more likely to view and reply to messages.
• Reduce account risk: Group postings to silent accounts are easily marked as spam, and active accounts have a low complaint rate.
• Cost Saving: Only conduct follow-up marketing to high-value numbers to avoid wasting resources through invalid sending.

Taking KK-DATA as an example, you can first submit the “tg activation” task for the US tg number, then superimpose the “tg active” task on the activated number, and set different active windows such as 3 days, 7 days, 30 days, etc., and finally output hierarchical data.

Preparation before screening: What data and tools do you need?

Before you start screening, make sure you have the following elements ready:

• Original number list: It can be a CSV/TXT file accumulated by yourself (including the US +1 number segment), or you can use KK-DATA’s [Global Number Generation] (https://kkdata.cc/) module to randomly generate US numbers.
• KK-DATA account and balance: Register for the console (https://app.kkdata.cc/), and you can use it after depositing USDT (TRC20). Generating numbers is free, and screening numbers will be deducted on a per-item basis.
• Data deduplication: Use the platform’s built-in “data deduplication warehouse” to eliminate numbers that have been detected to avoid repeated deductions.

Number source: Global number generation and own list

• Global number generation: Enter the console → “Number generation” module → select the country “United States” (+1) → specify the number segment (such as 415 San Francisco, 212 New York) → export CSV after generation. The generation process does not consume the balance.
• Own List Upload: Paste or upload your number text (one per line) into the task input box. TXT and CSV formats are supported and the platform will automatically parse them.

Balance check and deduplication

Operation method: Upload the list in the “Data Deduplication” function of the console, and the system will automatically compare and return the number of “newly added” numbers. These new numbers are then used for screening tasks.

Step 1: Submit the “Activation Detection” task of the US TG number

1. Log in to KK-DATA Console → select “Telegram Screen Number”.
2. In the “Number Import” area, upload or paste your US TG Numbers list.
3. Select the detection type “tg activation” (that is, register for detection).
4. Confirm that the balance is sufficient to cover the estimated cost (the system will display the estimated cost) → Submit the task.
5. Wait for the task to complete (usually a few minutes to a few hours, depending on the number of numbers) and download the resulting CSV.

Interpretation of results:

• tg开通 Field: 1 means registered on Telegram, 0 means not registered.
• phone Field: Original mobile phone number.
• tgid Field: Telegram user’s unique numeric ID.

How to interpret the “tgid” field in the activation detection result?

tgid is a unique numerical ID assigned to each user by Telegram (similar to WeChat’s openid). Its uses include:

• Deduplication: The same user still has the same tgid under different numbers, which can be used to filter duplicates.
• Targeted Operation: Some third-party tools support sending messages through tgid without relying on mobile phone numbers.
• Exclude contacted users: Add the contacted tgid to the blacklist to avoid repeated interruptions.

Note: tgid cannot be reversed mobile phone number.

Step 2: Overlay “Activity Detection” - How to set the active window?

The activation test only tells you that the number is registered with Telegram, but it cannot determine the user’s recent activity. Next, perform “tg active” detection on the activated number and specify the active window.

Operation process:

1. On the “Telegram Screen Numbers” page of the console, import the “Activation” list exported in step 1 (only the numbers tg开通=1 are retained).
2. Select “tg active” for the detection type.
3. Set the active window: Common options are 3 days, 7 days, 14 days, and 30 days (some scenarios can be customized, whichever is provided by the console).
4. Submit the task and wait for the results.

Applicable scenarios for different active windows (3 days, 7 days, 30 days)

Active window	Recommended scenarios	List size	Response rate expectations
3 days	Promotions, limited time offers, urgent notifications	Smaller (most active)	Highest
7 days	Daily private message contact, community invitations	Medium	High
30 days	Brand cold start, content push, industry trends	Large (including weekly active users)	Medium
90 days or more	Long-term maintenance, reaching silent users	Very large	Low (not recommended for active private messages)

Select Strategy:

• If your customer acquisition goal is high conversion rate (such as selling courses, promoting paid products), it is recommended to first use a 3-day or 7-day window to acquire the most active users.
• If it’s Brand Exposure or Content Marketing, use a 30-day window to expand reach.
• Don’t start with a 90-day window – many users may log in only once every six months, resulting in extremely low response rates.

Step 3: List stratification and export—Grade U.S. TG numbers according to activity

Based on the activation and active detection results, you can divide the original list into three tiers:

Stratification	Conditions	Operation Strategy
High activity	tg activation=1 and tg active=1 (online within the window period)	Priority private messages, community invitations, promotions
Low Activity	tg activated = 1 but tg active = 0 (not online during the window period)	Second verification (such as changing the window and testing again) or suspending sending
Invalid	tg activation=0	Delete to avoid wasting resources

Export operation:

• In the task results, use the filter function to check tg活跃=1 and export it as “High Activity List.csv”.
• Re-filter tg活跃=0 and tg开通=1 and export as “Low Active List.csv”.
• tgid, phone, 国家代码 and other fields can be exported at the same time for subsequent differentiated automated marketing.

Tips: Add a timestamp to each exported file to facilitate subsequent tracking.

Is the active window set too long or too short? Common misunderstandings and optimization suggestions

• **Myth 1: The shorter the window, the better. ** For example, if you only set a 1-day window, the list you get will be very small (maybe less than 10% of the total number of activations), and the coverage will be too narrow.
• **Myth 2: The longer the window, the better. ** Set a 90-day window. Although the list is large, it contains a large number of users who logged in only a few weeks ago and are now inactive, so the response rate drops.
• **Myth 3: One time is for life. ** The active window is not fixed and should be flexibly adjusted according to the business stage.

Optimization suggestions:

1. Small batch test first: Take 5,000 US TG numbers and run them once every 3 days, 7 days, and 14 days, compare the response rates of each window (you can use a free messaging tool to test), and find the best balance point.
2. Refresh regularly: Highly active lists also have a “shelf life” - users who were active for 7 days a month ago may now become silent users. It is recommended to retest the core list regularly (such as monthly).
3. Combined gender/age targeting: KK-DATA’s tg gender detection can also return the user’s gender, age and other fields (approximately 30-year-old people, etc.), which can achieve more accurate crowd screening when superimposed with activity.

FAQ

Question: When screening US TG numbers, must the activation test and active test be done in order?

Answer: Yes, it is strongly recommended to do the activation test first, and then do the activity test on the activated number. This avoids performing active detection on invalid numbers and saves costs. KK-DATA’s task system supports directly inputting the activation results as downstream tasks, which is very convenient.

Question: How many days is appropriate to set the active window for a US TG number?

Answer: It depends on reaching the target. Generally, a 7-day window is recommended for B2B overseas customer acquisition, which can balance the list size and response rate; 3 days can be used for short-term and quick promotions; 30 days can be used for brand content warm-up. It is recommended to test different windows in small batches first, compare the export quantities, and then decide to execute in full.

Question: How to prevent the filtered US TG numbers from containing a large number of silent accounts?

A: The key is to use “active detection” rather than just “open detection”. The activation test can only confirm that the number has been registered with Telegram, but it cannot determine recent usage. Overlaying activity detection (such as a 7-day window) can filter out accounts that have not been online for several months, significantly improving reach efficiency.

Question: What is the use of “tgid” in the filter results?

Answer: tgid is a unique numeric ID assigned to each user by Telegram. After exporting the tgid, you can use it to remove duplicates, exclude contacted users by adding followers, or perform targeting operations in other tools (such as specifying the tgid instead of the mobile phone number when sending a message). Note: tgid cannot reverse the mobile phone number.

Question: Can I submit a task when my balance is insufficient?

Answer: No. KK-DATA adopts a per-item withholding fee model. Before submitting a task, the system will check whether the balance is sufficient to cover the estimated fee. When the balance is insufficient, the task submission button is unavailable. You can recharge via USDT (TRC20) on the console, with a minimum of about 50 USDT, and the balance will be automatically updated after arrival.
