How to determine the re-screening period for valid TG numbers in the United States? Full analysis of number status changes, task timestamps and update trigger conditions

In overseas marketing, US valid TG number is the core resource to reach North American users. However, after many teams get a batch of “Telegram activation numbers”, they use them repeatedly as permanent assets. It is not until they find that the message delivery rate plummets that they realize that the data has expired. In fact, the Telegram platform itself regularly cleans up silent accounts, users log out, and are banned. Today we use a complete guide to dismantle the re-screening cycle of US TG valid numbers, the reasons for number status changes, and how to use task timestamps and update trigger conditions to keep the data fresh.

What is a valid TG number in the United States? Why is rescreening necessary?

Valid tg number in the United States refers to a number that is registered and activated on Telegram (that is, can receive messages). But “valid” is a dynamic indicator - a number that can receive messages normally today may be marked as a “dead account” by Telegram because the user has canceled their account, been officially banned, or has not logged in for more than 6 months, and thus cannot receive your marketing information.

A screening number result only represents the status at the time of detection. If you screen out a batch of U.S. Telegram activation numbers in January and then use the same batch of data to send in March, 20%–40% of the numbers may have expired. The essence of re-screening is “data preservation”: through re-detection, invalid numbers are eliminated and active numbers are retained to avoid wasting budgets due to invalid contacts.

Dynamic characteristics of valid TG numbers in the United States

The main reasons for number status changes include:

• Telegram Official Cleanup: The platform regularly deletes accounts that have not been logged in for a long time (usually inactive for more than 6 months).
• User voluntary logout: After the user actively deletes the account, the number becomes unactivated.
• Account Restricted/Banned: Due to violation of platform rules, the account has been frozen and cannot receive messages.
• Activity downgrade: Although the number is still active, the user has not been online for a long time and is in the “inactive” state. After sending a message from this type of number, the other party may not check it in time.

Cost comparison between re-screening and non-re-screening

Strategy	Single investment	Long-term results
No re-screening	0 yuan (use old data directly)	High invalid reach rate, waste of message sending resources, low conversion rate
Regular re-screening	Pay-per-item billing (see [Console Real-time Price] (https://app.kkdata.cc/) for details)	Eliminate invalid numbers before each sending, increase the reach rate by more than 50%, and achieve a higher ROI

Taking KK-DATA as an example, fees are deducted per screen number and there is no subscription package. Suppose you spend 100 to send 100,000 messages, but only 50,000 actually reach the other party, which is a waste of50. Spending US5 to re-screen the number library can avoid the waste of US50 - a small investment can lead to large savings.

How to judge whether your US TG activation data needs to be re-screened?

There is no need to wait for a fixed time. If any of the following four signals appears, rescreening should be started immediately.

The interval between the last screening time and the current time

• High frequency sending team (message sent every day) → Rescreening every 1–2 weeks
• Medium frequency sending team (sending 2–3 times a week) → Rescreening once a month
• Low-frequency sending team (1–2 times a month) → Re-screening before each sending

The interval recommendation is not absolute. You can dynamically adjust it by comparing the “activity rate/activation rate” statistics in historical tasks on the console.

Early warning signs that the activity rate in historical tasks has dropped significantly

Log in to the Application Console to view the “Opening Rate” or “Activity Rate” statistics of past Telegram account screening tasks. If it is found that the activity rate of a certain batch of numbers has dropped by more than 10% compared to the previous batch, it means that the number pool is seriously aging and must be rescreened.

For example: the activity rate of a batch of numbers you screened out in January was 85%, but after a small sample of the same batch of numbers was tested in February, the activity rate was only 70% - this shows that a large number of users were lost during this period.

Correct steps for re-screening valid TG numbers in the United States

Based on the KK-DATA platform, re-screening does not require re-collecting numbers from scratch. It only needs to use historical export files or data to deduplicate the warehouse and go through the “import→detection→export” pipeline.

Step 1: Export the filtered number list and prepare CSV

On the historical task page of the console, find the last screening result and download the CSV or TXT file. The file contains fields for each detection (such as TG activation, TG active, gender, etc.). You only need to keep the number column (remove other fields), or directly export the number set in the [Data Deduplication Warehouse].

Note: If the previously exported file has many fields, you can directly delete the unnecessary columns and keep the pure numbers.

Step 2: Submit the rescreening task on the console

1. Log in app.kkdata.cc
2. Select the [Telegram Screen Number] detection type
3. Upload CSV/TXT file
4. Check the detection items you need, for example:
   • tg activation (required to check if the number is still registered with Telegram)
   • tg active (optional, further filter users who have logged in recently)
   • tg Gender/Age (optional, if you need to target people)
5. The system will display the estimated cost (calculated based on the unit price of the current detection type, see the console for details)
6. Confirm submission

Step 3: Receive task completion notification and export new data

It is recommended to turn on Telegram task notification (bind your Telegram in the console settings), and you will receive a reminder after the task is completed. Enter the task details page and click Export to get the latest results. You can compare the old and new data to see how much the number status has changed.

How to avoid repeated deductions during re-screening? Tips for using data deduplication warehouse

Many people are worried that re-screening will result in repeated deductions - testing the same number twice and spending extra money. KK-DATA’s built-in data deduplication warehouse can solve this problem.

Effective conditions for deduplication warehouse

• The system determines whether it is duplicated based on the combination of “Number + Detection Type”. If you have previously checked the “Telegram activation” of a certain number and submit the “Telegram activation” task for the same number again, the system will skip the number and no fee will be deducted.
• However, if you only checked “tg activated” before and want to check “tg active” this time, or add the “tg gender” option, it will be regarded as a new detection type, and all numbers will be billed normally.

Therefore, it is recommended that when screening for the first time, you should check all the test items that you may use in the future (such as activation + activity + gender) at once, so that in subsequent re-screenings, as long as the test type remains the same, you can enjoy deduplication and no deduction.

How to manage the number pool in historical tasks?

• It is recommended to store numbers from different countries and for different purposes separately to avoid confusion.
• Regularly clean up useless numbers (such as numbers that have been confirmed to be canceled) in the deduplication warehouse to keep the warehouse clean.
• Use the “Export Number Set” function of the console to export and back up historically detected numbers.

Best practice suggestions for re-screening cycles of valid TG numbers in the United States

Based on the operational experience of the overseas team, we summarize the following re-screening cycle references:

Usage scenarios	Recommended rescreening cycle	Remarks
Cross-border e-commerce promotion period (Black Friday, Prime Day, etc.)	Re-screening every 3 days	Intensive sending, high risk of number invalidation
Regular content push (daily message volume >10,000 messages)	Rescreen every 1–2 weeks	Maintain activity rate above 80%
Accurate private message promotion (less than 5,000 messages sent per week)	Re-screening before each sending	Small amount of data, controllable single cost
Data storage (not used temporarily)	Re-screen before use	Almost all long-term stored numbers are invalid

Key principle: The cost of data preservation is far lower than the waste of invalid access. If you find that the activity rate of a certain batch of numbers drops by more than 10% twice in a row, it means that your rescreening cycle needs to be shortened.

Scenario-based case studies: real application from re-screening to efficiency improvement

Note: The following is a fictional scenario used to illustrate the method and does not represent real customer data.

For example, a typical overseas team is promoting VPN services to the North American market. They have a batch of US valid TG numbers screened out 3 months ago, and the activity rate at that time was as high as 82%. The team directly used this batch of data to send 100,000 messages, but only reached 65,000 users (actually activated and active numbers), with a reach rate of 65%, and wasted 35,000 sending quotas.

They then submitted a re-screening task on KK-DATA and checked “tg activated + tg active”. The re-screening results show that only 68,000 of these numbers are still open to Telegram (the activation rate is 68%), of which only 42,000 are active (online within the last 30 days). The team re-exported the active numbers and sent them to these 42,000 people with high-quality copywriting. In the end, the message open rate increased to 35%, and the conversion rate was twice as high as before.

The cost of re-screening (billed per item, see the console for details) is far lower than the wasted sending quota of sending all numbers directly. This is the value of data preservation.

Precautions and common misunderstandings

• Misunderstanding 1: Screen once and it will be effective forever. Number status changes at any time and must be rescreened regularly.
• Misunderstanding 2: Ignoring duplicate warehouses leads to repeated deductions. Before submitting for rescreening, make sure that the detection type is consistent with the historical task before deduplication can be triggered.
• Misunderstanding 3: Mismatch of detection types leads to invalid data. For example, if you only screen for “activated” but think the number is “active”, in fact the other party may not have logged in for a year.
• Misunderstanding 4: Not paying attention to task timestamps. Each exported result corresponds to a detection time point, and only by recording the timestamp can data changes be compared.
• Misunderstanding 5: The rescreening interval is too long. If the frequency of sending is high, it is recommended to rescreen at least once a month.

FAQ

**Q: How often is it appropriate to rescreen a valid TG number in the United States? **

Answer: It depends on your frequency of use and number level. If you send a large number of messages every day, it is recommended to rescreen every 1-2 weeks; if you use it infrequently, once a month can meet the basic freshness needs. Specifically, it can be dynamically adjusted based on the activity rate change trend in the historical tasks of the console.

**Q: How to avoid repeated deductions for numbers that have already been tested during re-screening? **

Answer: Use the data deduplication warehouse function of KK-DATA. When submitting a new task, the system will automatically compare the same detection type numbers in historical tasks, and no repeated deductions will be made. However, if the detection types are different (for example, the last check was only enabled, but this time the check is active), duplication cannot be removed.

**Q: The results obtained after re-screening are different from last time. What is the reason? **

Answer: The number status changes dynamically. Possible reasons include: the detected number has canceled its Telegram account, been officially banned, has not logged in for a long time, resulting in downgraded activity, or the active window you selected this time is different from last time. This is a normal phenomenon and is exactly the value of re-screening.

**Q: Can I check enabled and active at the same time in one task? Is rescreening more efficient this way? **

Answer: Yes. KK-DATA supports selecting multiple detection items in one task (such as tg activation + tg activity + gender detection, etc.). In this way, you only need to submit the number file once to obtain results in multiple dimensions, which is more efficient, and only the number of items actually detected is billed.

**Q: Are the data fields exported after re-screening consistent with the first screening number? **

Answer: The fields depend on the detection items you checked in this task. Normally, if you check the same detection item, the exported fields will be the same as before, but the data values ​​will be updated to the current state. It is recommended to save a copy of the time-stamped data every time you re-screen to facilitate comparison and analysis.
