How to determine the rescreening period for tg US data? Detailed explanation of number status changes, timestamps and update trigger conditions

If you are running a Telegram marketing campaign for the US market and have a batch of tg US data in your hand, but are not sure whether this batch of numbers can still be used - then this article is for you. tg US data is not static: users will log out of their accounts, change devices, adjust privacy settings, activity may drop from “high” to “silent”, and even gender recognition fields will become invalid due to data updates. How to scientifically set the rescreening cycle to ensure that Telegram US data always has a high reach rate is a core skill that the overseas operation team must master.

This article will combine the functions of the KK-DATA platform to break down in detail the three types of number status changes, the judgment method of task timestamps, and the typical scenarios that trigger rescreening. Finally, specific rescreening operation steps are given. Whether you are a novice operator who is coming into contact with US tg data for the first time, or you are a veteran who wants to optimize your existing data preservation strategy, you can get practical suggestions from it.

What is tg US data re-screening? Why do you need regular updates?

Rescreening refers to re-verifying the activation, activity, gender and other fields of the phone number that has been detected. Different from the first screening of numbers, the goal of re-screening is to “refresh the status of existing data” rather than to obtain new numbers from scratch.

Why do we need regular re-screening? The reason is simple: number status is dynamic. Taking TG US number data as an example, the following situations will occur frequently:

Cancellation or Recycling: After a user cancels their Telegram account, the number will become “unregistered”; after some numbers are recycled by the operator, new users’ registration of Telegram will also cause ownership changes.
Activity Fluctuation: A user who has logged in frequently may not log in for several months due to changing the main platform, vacation or privacy concerns, and the activity level drops from “active within 7 days” to “inactive for 30 days”.
Identification field changes: Public information such as gender, age, avatar, etc. may be modified or hidden by the user, causing the previous gender/age identification results to become invalid.

If re-screening is not performed, the US tg data in your hand will gradually “rotten”, manifested as a drop in delivery rate, a drop in open rate, or even the account being marked as harassment. Therefore, data preservation is a necessary investment to improve marketing ROI, and setting a reasonable re-screening cycle is the key.

Three possible changes in tg US data status

Activation status change: from valid to invalid

Activation detection Determine whether a number is registered with Telegram. You may encounter the following situations that cause the status to change from “Activated” to “Not activated”:

The user actively logs out of his Telegram account.
The number was recycled by Telegram if it was not logged in for a long time (rarely happens, but it does happen).
The original user changed the SIM card and the new user did not register Telegram.

Recommended rescreening frequency: For the “open” status in tg US data, if the data is taken within 30 days, a higher confidence level can usually be maintained; if it exceeds 30 days, it is recommended to rescreen every 2–3 months. If used for high-value marketing (such as financial, educational products), it can be shortened to 1 month.

Activity changes: from high activity to silence

Activity detection is the core factor that affects the reach effect. Telegram will record the user’s last online time (providing a certain degree of accuracy), and divide the activity levels through windows such as “active in 7 days”, “active in 30 days”, and “active in 90 days”. But the active window will naturally expire over time:

A user who was last detected as “active for 7 days” may become “inactive for 15 days” after 7 days.
Even if the user is still registered but has not logged in for 90 days, your messages may not be visible.

Recommended rescreening frequency: Activity data is most sensitive to timeliness, and it is recommended to rescreen within 7–14 days**. If you need to maintain a reach rate of more than 80%, it is best to rescreen the “active” field every week; if the business tolerance is high, it can be extended to 30 days.

Gender/age field changes: unstable recognition results

Gender identification relies on the user’s public information on Telegram (nickname, introduction, avatar, third-party information bound to mobile phone number, etc.). These information may be modified at any time: users may delete their avatar, change their nickname, or turn off the “view avatar” function. Therefore, the gender field that was last recognized may not be recognized at all (become “unknown”) a week later, or the recognition result may change (such as from male to female, with a lower probability but still present).

Recommended frequency of rescreening: If your business requires precise gender targeting (such as marketing to female users), it is recommended to rescreen the “gender” field before each use; if it is for reference only, you can rescreen it every 2–4 weeks.

Data preservation recommendations

The activity field in TG US data is most affected by time. If the interval between your rescreening tasks exceeds 30 days, it is recommended to rescreen “activity” first, and then rescreen “activation” and “gender” as needed.

How to determine whether the data needs to be re-screened based on the task timestamp?

Each screen number task of KK-DATA has a clear completion timestamp, which is recorded in the task list of the console. You can compare this timestamp with the current time to determine how old the data is.

The following is a reference table to help you make quick decisions (based on general experience, please combine with actual business needs):

Detection fields	Recommended data retention period	Description
Activation status	30 days	If the last activation test is within 30 days, the status can be considered stable; if it exceeds 30 days, re-screening is recommended.
Activity	7–14 days	Highest sensitivity, it is recommended to rescreen every week or every two weeks.
Gender/Age	7–14 days	The identification results are subject to change. It is recommended to rescreen before each use; for reference only, it can be extended to 30 days.
Comprehensive (all fields)	14–30 days	Re-screen three fields at the same time, suitable for high-quality data requirements.

How to check the timestamp: Enter the KK-DATA console → Task list, and “Completion time” will be displayed on the right side of each task. Copy this time and subtract it from the current date to determine whether rescreening is needed.

Update trigger conditions—when should a new round of rescreening be started?

In addition to relying on timestamps, there are some more intuitive signals in actual operations that can trigger rescreening actions.

The reach rate dropped significantly

When using tg US data to send promotional messages, if the delivery rate (the proportion of messages accepted by the server) and the open rate (the proportion of users clicking/reading) drop by more than 10% for 3 consecutive days, it can basically be concluded that the data has aged. At this time, rescreening should be started immediately, with priority being given to checking the “Activity” field.

Key events/festival warm-up

For important marketing nodes in the US market, such as Thanksgiving (end of November), Black Friday (November), and Christmas, it is recommended to re-screen the target tg US data 1–2 weeks in advance. This ensures that the number is active on the day of the event and avoids wasting budget due to data failure.

Data is used across months

If the last screening number exceeds 30 days (i.e., the natural monthly cycle), regardless of whether the current reach rate has dropped significantly, it is recommended to rescreen the “open + active” fields at least once. Cross-month data often accumulates a large number of expired numbers. Re-screening can help you quickly clean up bad numbers and save bandwidth and costs for subsequent push.

tg US data re-screening operation steps (KK-DATA platform as an example)

The following takes the KK-DATA platform as an example to explain how to perform a re-screening task on an existing TG US number.

Import original number Log in to the Console, and in the “Screen Number” module, upload the TG US Number CSV/TXT file you exported previously. Supports up to 1 million records at a time.
Select detection type Check fields based on rescreening goals:
- If you only need to refresh the “Activity”: Just check Telegram Active and set the activity window (such as 7 days/30 days/90 days).
- If you need to update “Activation” or “Gender” at the same time: Check the corresponding Telegram activation and Telegram Gender.
Set active window (optional) If activity detection is checked, you need to specify the activity window. For example, if you select “7 days active”, the platform will determine whether the number has logged in in the past 7 days.
Enable data deduplication warehouse (recommended) In the task settings, turn on the data deduplication warehouse function. It automatically filters out numbers that were last detected and whose status has not changed, and only re-detects numbers that may have changed. According to official documentation, this feature can save approximately 50% of inspection costs.
Submit task Confirm the estimated fee (the console will display the estimated deduction amount for this task), and submit it after checking it is correct. When the task is completed, you will receive a Telegram notification (if bound), or download the results directly in the console.
Compare data before and after After downloading the results, compare with the previous data and pay attention to the proportion of numbers that changed from “activated” to “unactivated” and “active” to “inactive”. If more than 15% of the number status changes, it means that the data quality of this batch fluctuates greatly, and it is recommended to shorten the next rescreening cycle.

Tips for re-screening

Using KK-DATA’s “Data Deduplication Warehouse” function, you can automatically filter out numbers that were last detected and whose status has not changed, and only re-detect numbers that may have changed, thus saving about 50% of detection costs.

FAQ

**Q: How long does it take to rescreen tg US data? ** Answer: It depends on the number of numbers. For example, if 10,000 pieces of tg US data complete the “open + active + gender” re-screening, the results can usually be returned within a few minutes. Please refer to the console task progress for the specific time. The platform supports real-time viewing.

**Q: Do I need to re-select all test types during re-screening? ** Answer: It is recommended to choose based on actual needs. If you only care about whether the activity level has changed, you can only select “Activity” detection, and there is no need to repeatedly detect “Activation” or “Gender”. This saves testing costs.

**Q: How do I know the time of the last screening? ** Answer: In the task list of the KK-DATA console, each task has a clear “Completion Time” field that can be viewed directly. You can also export task logs as records.

**Q: Is the unit price of TG US data re-screening the same as the initial screening? ** Answer: Yes, the fees for re-screening and preliminary screening will be deducted according to the same standards. The specific unit price varies depending on the platform and detection type. Please refer to the real-time price of the console or the official website billing page for details.

**Q: If it is found that the number status has not changed after re-screening, is it a waste of money? ** Answer: The change in number status is an objective fact, and rescreening is to confirm the current status. If the number status is stable, it means that the data quality of this batch is high and you can continue to use it with confidence. And through the data deduplication warehouse function, you only pay for numbers that may change, without full detection.

Through reasonable re-screening cycles and trigger strategies, you can continue to maintain high-quality tg US data, making every marketing contact more efficient.
