US Telegram Number Activity Detection: How to Precisely Filter Highly Active Telegram Users (Activity Window Selection Guide)

When doing Telegram marketing in the US market, have you ever encountered this situation: the US number list in your hand clearly shows “valid,” but after sending messages, users show no response, and the open rate is so low it makes you doubt everything? The key isn’t whether the number is registered with Telegram, but whether the number holder has actually been using Telegram recently. This is the core issue that US Telegram number activity detection solves—it helps you filter out “highly active” users from a massive pool of numbers, concentrate marketing resources on the targets most likely to respond, and significantly improve customer acquisition ROI.

This article will provide you with a practical guide that can be directly implemented, covering the definition of activity detection, the logic for selecting activity windows (7-day/15-day/30-day), the complete operation steps, and interpretation of results. Whether you are an e-commerce independent station operator, a community growth team expanding overseas, or a Telegram group promotion studio, you will find methods here to improve efficiency.

What Is US Telegram Number Activity Detection? Why Is It More Important Than “Valid”?

US Telegram number activity detection not only verifies whether a number is registered with a Telegram account but also checks whether that account has shown active behavior (such as logging in, sending/receiving messages, online status, etc.) within a specified time window (e.g., 7 days, 15 days, 30 days). Compared to simple “validity detection,” activity detection more accurately reflects the current usage value of a number.

Valid Numbers vs. Active Numbers: What’s the Core Difference?

Detection Type	Basis for Judgment	Marketing Significance
Valid Number	The number is registered with a Telegram account	Can receive messages, but the user may have abandoned the account or rarely checks
Active Number	Has logged in or engaged in message interaction within the specified window	The user has recently used Telegram, making them more likely to see and respond in a timely manner

A number can be “valid but not active”—this is common in the US market. For example, a user might have registered and downloaded Telegram once but never opened it again. If you only perform valid detection, you might waste your budget and energy sending messages to these “zombie numbers.”

Why the US Market Especially Needs to Focus on Activity?

• Users have scattered online hours: The US spans multiple time zones (Eastern/Pacific/Central), and users in different industries have different active times. Activity detection helps you locate users who “were just using the app,” increasing immediate reach rates.
• Large industry differences: For scenarios requiring high response rates, such as e-commerce promotions or financial campaigns, prioritize 7-day active users. For brand exposure or notification-type pushes, you can choose 30-day active users to cover a broader audience.
• Reduce the risk of being blocked or reported: Frequently sending messages to inactive users may trigger Telegram’s anti-spam mechanism. Activity detection makes every touch more targeted.

How to Choose an Activity Window? 7-Day, 15-Day, and 30-Day: Which Fits Which Scenario?

KK-DATA supports three activity windows: 7-day, 15-day, and 30-day. The shorter the window, the higher the “real-time activity” of detected users, but the number of qualifying samples may be smaller. The longer the window, the more potential active users it covers, but the average activity level decreases.

Short-Term Activity (7-Day Window): Suitable for Immediate Promotions and Time-Limited Events

Applicable scenarios:

• Time-limited discounts or flash sales released today or this week
• Customer service or confirmation messages requiring a response within 24 hours
• Live stream previews or webinar invitations (usually pushed 1–3 days before the event)

Effect: Users active within 7 days typically have the highest message open and click rates. If you aim for “immediate conversion” in the US market, the 7-day window is the top choice.

Medium-Term Activity (15-Day Window): Suitable for Regular Content Push and Community Growth

Applicable scenarios:

• 2–3 product updates or industry news pushes per week
• Community invitations (users may see the message but join the group a couple days later)
• Medium-frequency marketing touches that balance response rate and coverage

Effect: The 15-day window covers the vast majority of active users who have used Telegram recently, making it the most common choice for daily operations.

Long-Term Activity (30-Day Window): Suitable for Brand Exposure and Silent User Re-engagement

Applicable scenarios:

• Low-timeliness content like brand stories or user cases
• Re-engaging users who were once active but haven’t logged in recently (e.g., inactive for over 2 weeks)
• First-round outreach in a new market to gather reaction data

Effect: The 30-day window yields the largest sample size, but the average user activity is the lowest. Suitable for a “broad net” trial phase.

How to Perform US Telegram Number Activity Detection? Complete Operation Process

Below, we use the KK-DATA console as an example to demonstrate the four steps from preparing numbers to exporting results. These operations can all be completed on the official Application Console.

Step 1: Prepare US Numbers (Generate or Import)

• Random Generation: Use KK-DATA’s “Global Number Generation” function, select country “United States” (+1 prefix), specify the quantity, and the system will randomly generate US phone numbers that conform to the numbering plan.
• Custom Import: If you have your own number list (CSV or TXT format), you can upload it directly. Note that numbers must include the international country code, e.g., +14151234567.
• Prefix Generation: For specific US regions (e.g., New York, Los Angeles), you can use “Global Prefix Generation” to bulk generate numbers by the first few digits.

Number generation itself is free; only subsequent screening and detection are charged per record.

Step 2: Create a Detection Task and Set the Activity Window

1. Log in to the Application Console, go to “Screening Tasks” → “New Task”.
2. Select detection type as Telegram Activity Detection.
3. In parameter settings:
   • Check the country “United States” (you can also select only the US and skip other countries).
   • Choose the activity window: 7 days / 15 days / 30 days (based on the suggestions in the previous section).
4. Before confirming the task, the system will display the estimated cost (based on current unit price and number quantity).
5. Submit the task. If your balance is insufficient, you need to top up via USDT (TRC20) (minimum approximately 50 USDT).

Step 3: View Results and Export Active Numbers

• After submitting the task, you can check the progress in the task list. Upon completion, a notification will be sent via Telegram bot (you need to bind it in advance).
• Enter the task details to view a statistical summary: total numbers, valid count, active count, invalid count, etc.
• Click Export, and select CSV or TXT format. Each number in the exported file will include fields: Number, Valid, Active, Activity Window, tgid (if enabled), Gender (if enabled), etc.

How to Interpret US Telegram Activity Detection Results? Meaning of Common Data Indicators

After exporting the results, you may see the following fields:

Field	Example	Meaning
Number	+14151234567	Original phone number
Valid	true / false	Whether registered with Telegram
Active	true / false	Whether active within the specified window
Activity Window	7 days	The window used for this detection
tgid	123456789	Telegram account internal ID (can be used for API calls)
Gender	Male / Female / Unknown	Gender recognition based on avatar (optional, if enabled)

Why do some numbers show “valid but not active”?

This is normal. For example, the user may not have opened the app for a month after registering, or they have set complete invisibility (making detection difficult). Such numbers will be marked as “valid but not active.” You can consider adjusting the window to 30 days, or simply ignore this batch.

Meaning of invalid numbers: If “Valid” is false, the number is not registered with a Telegram account. It may have never been activated, the number may be deactivated, or the carrier may have restrictions. Such numbers should not be used for TG marketing.

What to Keep in Mind When Using Activity Detection? (Privacy, Cost, Accuracy)

Privacy and Compliance

• Activity detection is based on Telegram’s public online status and behavior signals. It does not involve reading users’ private message content.
• Some users enable “Privacy – Online Status” set to “Nobody,” which may cause activity detection to miss them. Such users may actually be active but are marked as “inactive.”
• It is recommended to treat activity detection as a reference indicator rather than an absolute standard. Final marketing strategies should also incorporate industry experience.

Cost Optimization

• Use Data Deduplication Warehouse: KK-DATA provides cross-task number deduplication functionality to avoid detecting the same number multiple times, wasting balance.
• Arrange batch sizes wisely: The maximum per batch is approximately 1 million records. If you have a large number of numbers, you can submit in batches and adjust based on feedback from the first batch’s results to avoid investing too much at once.
• Monitor balance changes: Detection tasks deduct from the balance upon completion; insufficient balance will prevent new task submissions. Real-time prices can be found on the official pricing page.

Factors Affecting Accuracy

• User privacy settings (invisibility/disable online status)
• Detection algorithm cannot cover all scenarios (e.g., user logged in only via PC client but not showing online)
• Numbers from virtual operators or disposable numbers (may be abandoned after registration)

Therefore, do not rely solely on the active label. It is recommended to combine with business data (e.g., historical conversion rates) to continuously optimize window selection and crowd strategies.

Frequently Asked Questions

Q: Can the results of US Telegram number activity detection be 100% accurate?
A: No, 100% accuracy cannot be guaranteed. Activity detection is based on Telegram’s public online status or recent behavior signals. Some users may set invisibility or disable online display, which can bias the activity judgment. It is recommended to treat activity detection as a reference indicator rather than an absolute standard.

Q: What is the difference between active and valid?
A: “Valid” means the number is registered with a Telegram account; “Active” means the account has logged in or engaged in message interaction within a specified time window (e.g., 7 days). A number can be “valid but not active.”

Q: Can I detect only US numbers?
A: Yes. When creating a detection task, you can select the target country as “United States.” The system will only execute detection for US numbers (+1 prefix); numbers from other countries will be skipped or not processed (depending on task settings). You can also directly generate US numbers using the global number generation function.

Q: How long does activity detection take?
A: The detection duration depends on the quantity of numbers submitted. The maximum per batch is approximately 1 million records and typically takes from a few minutes to a few hours. The task will show status updates, and you can receive notifications via Telegram upon completion, so you don’t need to stay on the screen.

Q: If a number shows as “invalid” after detection, do I still get charged?
A: Yes, detection tasks are charged based on the actual number of records detected, regardless of whether the result shows valid or active. It is recommended to use the data deduplication warehouse to filter out previously detected numbers and avoid repeated waste.
