tg filtering practice: do activation detection first to reduce invalid numbers and detection waste

When doing tg filtering (Telegram number screening), many people go straight to “activity detection” or “gender identification” as soon as they start. As a result, they spend a lot of balance, only to find that most of the numbers are not registered with Telegram at all, which is a waste of money. The correct approach is: Do the activation test first, confirm whether the number is valid (that is, registered with Telegram), and then decide on the next step of screening. This article will explain why “activating detection” is the first step in Telegram filtering from the three perspectives of cost, data quality and operation process, and provide a step-by-step guide that can be implemented.

What is tg filtering? Why do we need to pay attention to the validity of the number first?

tg filtering refers to the detection and screening of Telegram-related attributes on a batch of mobile phone numbers. Common detection types include:

• Activation detection: Determine whether the number has been registered with Telegram (valid number).
• Activity Detection: Determine whether the registered account has been online within the specified time window (such as 24 hours, 7 days).
• Gender/Age Detection: Identify the gender, age and other fields in the personal data bound to the account.

Most users tend to fall into a misunderstanding: thinking that “as long as the activity or gender is detected, high-intent users can be directly obtained.” In fact, any advanced detection is invalid if the number itself is not a Telegram user. With an unregistered number, the platform will not return any activity or gender data, but you have already paid for the test. Therefore, doing activation testing first and filtering out unregistered invalid numbers is the first step to reduce customer acquisition costs**.

Why does tg filtering need to be enabled first? Three key reasons

Reason 1: Avoid performing paid detection on unregistered numbers

KK-DATA adopts a per-item billing model (see [Console Real-time Price] (https://app.kkdata.cc/) for details), and the unit prices for different detection types are different. If you directly perform “tg active” detection on a batch of numbers, the system will try to query the activity status of each number - but 30% to 50% of them may be unregistered, and fees will still be deducted for these queries. Do the activation test first, keep only the activation number, and then do higher-level detection only on valid numbers. The balance saved is very considerable.

Reason 2: Improve the target quality of advanced filtering

Only numbers registered with Telegram may have active behaviors or carry gender information. First filter out the “valid number pool”, and then the subsequent test results such as “tg active” and “tg gender” will have practical significance. Otherwise, the reports you get will be mixed with a large number of “unregistered” results, which will interfere with data analysis.

Reason 3: Improve task execution efficiency

Batch screening tasks usually need to be queued. By performing activation detection first, a large amount of invalid data can be quickly eliminated and the amount of data in subsequent tasks can be reduced, thereby speeding up the overall processing speed. Especially when you have hundreds of thousands or even millions of numbers on hand, step-by-step screening can significantly shorten the waiting time.

How to check the activation of Telegram number? (step-by-step process)

The following uses KK-DATA Console to demonstrate the specific operation steps. The logic of other platforms is similar.

Step 1: Organize the numbers to be checked and import them into the platform

• Number format: Full international dialing code + number, for example 8613800138000. Remove spaces, dashes, and parentheses.
• File format: Supports CSV or TXT files, one number per line.
• Data volume: The maximum number of single tasks is about 1 million.
• **What should I do if there is no number? **: You can use KK-DATA’s “Global Number Generation” function to generate numbers randomly or according to number segments (free, only deducted during detection). Import directly after generation.

Step 2: Select “Telegram activation detection” and submit the task

1. Navigate to the left side of the console and select “Screen Task” → “New Task”.
2. Select Telegram as the detection platform.
3. Select tg activation (that is, enable detection) for the detection type.
4. Upload the prepared file or paste the number list.
5. The system will display the estimated fee (the balance must be sufficient). If the balance is insufficient, you need to recharge via USDT (TRC20) first, with a minimum of about 50 USDT.
6. Click “Submit Task” and the platform will start testing. You will be notified via Telegram when the task is completed.

Step 3: Export the “activation” result and build a valid number library

After the task is completed, the results can be exported on the task details page. Select the export format (CSV or TXT) and filter out numbers with status “Activated”. You can:

• Use these numbers directly to send group private messages or add followers on Telegram.
• Use it as an input pool for the next round of liveness detection or gender detection.

Open detection vs. active detection: when to use which?

Detection Type	Applicable Scenarios	Cost	Recommendations
Activate detection	Send private messages to groups and add followers	Lower (see the console for details)	Recommended as the first step to filter out invalid numbers
Active Detection	Accurately reach online users and require high response rates	Higher (due to the need for real-time query)	Used based on the activation test results

Scenario 1: Send private messages to groups/add followers

If the goal is just “as long as the number is registered with Telegram, you can receive messages”, activating detection is enough. Even if the other person is not online often, you will still be able to see the message the next time you open Telegram. Priority is given to activation detection, which can filter out 30% to 50% of invalid numbers, significantly saving sending costs.

Scenario 2: Accurately reach active/high-intent users

If you want to obtain users who have been online recently (for example, for promotion of big sales events), you need to perform tg activity detection on the valid number after activating the detection, and specify the active window (such as the past 7 days). The resulting user pool is of higher quality, but the cost also increases accordingly. Only by properly planning the testing levels can you spend your budget wisely.

Three best practices to reduce the waste of invalid numbers

1. Use data deduplication warehouse: Repeated submission of the same number will waste the balance. KK-DATA provides cross-task deduplication function to automatically eliminate detected numbers to avoid repeated deductions. Be sure to enable deduplication before submitting a task.
2. Set the active window reasonably: If you only need recent active users, do not choose a too short window such as “24 hours” to avoid missing users who log in on weekends or holidays. For B2B customer acquisition, a 7-day or 14-day window is often more appropriate.
3. Small batch test before large-scale submission: First test with 100 to 1,000 numbers to observe the data quality (such as activation rate, active ratio). After confirming that the results returned by the platform are in line with expectations, submit a large number of numbers to avoid waste caused by format errors or batch problems.

Recommended filtering paths:

**Number generation/import → Data deduplication → Telegram activation detection → Export valid numbers → (on demand) activity/gender detection → Export final list for customer acquisition. **

Each step can be completed through KK-DATA Console, with clear process and transparent billing.

FAQ

**Q: When tg filtering, what is the difference between open detection and active detection? ** Answer: The activation test only determines whether the number is registered with Telegram, which is a basic verification; the activity test further determines whether the registered account has been online within a specified time period (such as 24 hours, 7 days). It is recommended to perform activation testing first, and then perform activity testing on valid numbers to avoid wasting fees on unregistered numbers.

**Q: After a number is tested once for activation, does it need to be tested again next time? ** Answer: Submitting the same number repeatedly will waste your balance. It is recommended to use KK-DATA’s “data deduplication warehouse” function to automatically eliminate detected numbers across tasks to avoid repeated deductions.

**Q: Are the test results of tg filtering activation accurate? ** Answer: The detection is based on the public interface of the Telegram server to verify the account status, and the accuracy is high. However, it should be noted that the results may change after the number is canceled or the status is changed. It is recommended to conduct batch testing based on best practices before acquiring customers.

**Q: Can I just do the activation test and then send it to the group? ** Answer: Yes. After activating the test and confirming that the number is registered with Telegram, even if the other party is not often online, you can still receive private messages. However, if a high response rate is required, it is recommended to add “tg active” detection and select recently logged in users.

**Q: How to obtain a large number of numbers and do activation testing first? ** Answer: You can use KK-DATA’s “Global Number Generation” function to randomly generate numbers by country/region and number segment, or upload a custom number segment CSV, and then submit the activation detection task. It is free to generate and will be deducted only when testing.
