Complete Guide to Telegram Number Screening Data Refresh: Rescreening Cycles, Data Freshness, and TG Activity Judgment Strategies

If your overseas customer acquisition heavily relies on Telegram direct messages or community operations, you will inevitably face a core issue: the data in your number pool has “expired.” Numbers that showed as “TG valid” last week may suddenly see a cliff‑like drop in delivery rate, or even generate numerous “send failed” prompts. This is not caused by poor number quality itself, but by your failure to perform Telegram number screening data refresh — re‑detecting the status of numbers to restore “freshness” to your pool.

This article systematically explains why you need to regularly rescreen numbers, how to set rescreening cycles based on your business rhythm, how to execute a complete refresh operation, and how to optimize your outreach strategy after data refresh. Whether you are a high‑frequency team sending thousands of messages daily or a low‑frequency operator sending a round each week, you can find a data freshness solution that suits you.

What is Telegram Number Screening Data Refresh? Why is Regular Rescreening Necessary?

Data refresh (also called rescreening) means: submitting a number pool that has already been screened to a screening platform again to perform checks such as tg registered, tg active, tg gender, etc., and updating the real‑time status of each number.

Many people mistakenly believe that once a number is detected as “valid,” it remains valid forever. This is precisely the main reason for a drop in customer acquisition efficiency. The status of numbers on Telegram changes constantly — not refreshing is like navigating with an outdated map.

Can Number Data “Expire”? — Three Common Reasons for Status Changes

Change Scenario	Specific Performance	Impact
User uninstalls/account deleted	Registered but long‑term inactivity, account reclaimed by system or user voluntarily deletes	tg valid → invalid
Long‑term inactive	Has not opened Telegram for over 30 days or more	tg active → inactive
Account banned	Banned by Telegram due to spam, reports, etc.	tg valid → invalid

Additionally, numbers may become inactive due to user number changes, device changes, etc. When you pull numbers from previous screening results to send messages, you will notice many “not registered” or “last seen a long time ago” prompts — these are typical signals of expired data.

Relationship Between Data Freshness and Delivery Success Rate

Imagine you have a pool of 100,000 numbers. The initial screening shows 70,000 as “tg valid” and 30,000 as “tg active (within 7 days).” If you do not rescreen, after one month the valid ratio may drop below 50%, and the active ratio may be even lower. If you then send DMs based on active labels, the actual reachable users might be fewer than 10,000.

The degree of data freshness directly determines delivery efficiency and the reputation of your sending account:

• Sending to invalid numbers → waste of messaging costs (charged per message)
• Frequently sending to banned numbers → triggers sending limits or complaint risks
• Reaching only long‑term inactive users → extremely low reply rate, may be marked as spam

Regularly refreshing TG active status ensures that each time you reach out, your targets are users who have logged in recently and are truly interactive, thus improving reply rates and subsequent conversions.

How to Determine the Right Rescreening Cycle for You? — Derive from Your Customer Acquisition Scenario

There is no “one‑size‑fits‑all rescreening cycle.” You need to set it based on your own outreach frequency, pool size, and sensitivity to data freshness. Below are recommendations for typical scenarios.

High‑Frequency Outreach Scenarios (e.g., 1,000+ messages per day) — Recommended Rescreening Cycle and Reasons

If you send over 1,000 direct messages or bulk notifications via Telegram daily, then your number pool must maintain extremely high freshness.

• Recommended TG activity detection cycle: Every 7 days (or even shorter)
• Recommended TG registration detection cycle: Every 15 days

Reason: High‑frequency sending means many numbers you reach may quickly become invalid (user feedback, complaints, bans, etc.). If you use outdated activity labels, your sending plan will keep hitting invalid numbers, wasting balance and easily causing your sending account to be restricted. Before sending each day, at least ensure you have activity data from the most recent 7 days.

Low‑Frequency Outreach Scenarios (e.g., weekly or monthly sending) — Balance Freshness and Cost

If your customer acquisition rhythm is one round per week or per month, you do not need to refresh as often as high‑frequency teams, but you still need to perform a “one‑time refresh” right before each sending round.

• Recommended rescreening cycle: Execute a complete refresh (TG registration + TG activity) right before each planned send
• Or fixed cycle: Perform TG validity detection every 15‑30 days; TG activity can be extended to 30 days

In this rhythm, you care more about “the number is still registered” than “recently active.” If you notice an abnormal reply rate after sending, you can shorten the TG activity window to 7 days. The pay‑per‑message billing model allows you to adjust on demand without paying high subscription fees.

How to Execute a Complete Telegram Number Screening Data Refresh? (Step‑by‑Step Guide)

Below, we use the KK‑DATA platform as an example to demonstrate a standard refresh process (the platform is only an example; the core logic is universal).

Step 1: Import or Generate Numbers

• If you already have a number pool (CSV/TXT), directly upload the number list.
• If you do not have numbers, you can use the “Global Number Generator” function to randomly generate numbers for target countries, or import by number range in batches.

Step 2: Select Detection Types

When rescreening, you usually need to check one or more of the following:

• tg registered: Detects whether the number is registered on Telegram
• tg valid: Detects if the number is registered and currently able to receive messages
• tg active: Detects if there has been login activity in the last 7/15/30 days (window can be specified)
• tg gender: Identifies gender via avatar (optional)
• Export tgid: Obtains the user’s Telegram ID

Recommendation: If this is a complete freshness refresh, select both tg registered and tg active. If you only want to optimize sending targets, just select tg active with a 7‑day window.

Step 3: Submit the Task and Set Notifications

The system will display an estimated cost (charged per message; actual fee is based on task results). After confirmation, submit the task and it will be processed asynchronously. It is recommended to enable Telegram task completion notification, so you do not have to keep watching the console.

Step 4: Wait for Task Completion

A single task supports up to about 1 million numbers and usually completes in minutes to tens of minutes. You will receive a Telegram notification when finished.

Step 5: Export Results

Supports CSV, TXT, etc. It is recommended to export including the tg active field for subsequent layered operations.

After Data Refresh, How to Optimize Outreach Rhythm with New Data?

Rescreening is not just about “seeing the latest status” — the important part is action. After obtaining the refreshed results, it is recommended to reorganize your number pool according to the following layered strategy:

Label Combination	Characteristics	Recommended Outreach Strategy
tg valid + active (7 days)	High‑quality leads, recently online	High frequency priority: Can be sent daily, high reply rate
tg valid + active (15‑30 days)	Possibly online occasionally	Medium frequency: Send once per week, try to re‑engage
tg valid + inactive	Registered but long‑term no login	Low frequency verification: Send one verification message; if no response, shelve
tg invalid	Unsubscribed/banned	Immediately remove to avoid wasting balance later

Note: Do not treat all numbers equally. Concentrate high‑quality active numbers into your primary sending tasks; reduce frequency for low‑activity numbers, or combine with other channels (e.g., email) for secondary touch.

The Role of a Deduplication Repository in the Refresh Process

When you repeatedly perform Telegram number screening data refresh on the same number pool, you may encounter a problem: the same number gets detected multiple times, incurring repeated charges.

KK‑DATA provides a Deduplication Repository, which acts as a central “number blacklist/whitelist”:

• When you submit a new task, you can choose to enable deduplication, and the system will automatically filter out numbers already in the repository
• A number will be re‑detected and charged only when its status has changed (e.g., previously “valid”, now needs re‑testing)
• The deduplication repository works across tasks; whether you generate or import numbers, you do not need to manually deduplicate

In other words, when refreshing, you only need to focus on numbers that need re‑detection, rather than rescreening the entire pool repeatedly. This effectively controls costs, especially for large number pools.

Data Freshness Checklist (Checklist for Execution)

Before/after each data refresh, go through the following items:

• Have you set the next rescreening date? Mark a reminder in your calendar or task management tool
• Have you enabled task completion notification? Saves waiting time
• Have you layered the number pool by activity? Store results in different labels
• Have you removed useless numbers? Move invalid or long‑term inactive numbers out of the main pool
• Have you disabled unnecessary detection types? Only select the types you actually need to avoid waste
• Have you checked the current records in the deduplication repository? Avoid re‑testing numbers already present
• Have you recorded the actual delivery rate from this rescreen? Use it to adjust the next cycle

Frequently Asked Questions

Q: After one Telegram number screening data refresh, how long can the number status remain unchanged?

Any number’s status is dynamic and never “permanently valid.” For transactional or high‑value leads, it is recommended to refresh TG activity every 7‑15 days; for common pools, refresh TG registration once every 30 days to maintain basic freshness. If your business requires extremely high delivery rates, shortening the cycle to 3‑5 days is not excessive.

Q: Will rescreening cause repeated charges? How to avoid it?

Charges are based on the number of detections. However, with the deduplication repository, only new or status‑changed numbers are charged. KK‑DATA shows an estimated cost before submitting a task, so you can control your budget. Also, refreshing only the necessary detection types (e.g., only activity) and not selecting TG registration or gender can save costs.

Q: When rescreening, should I detect both “tg registered” and “tg active”?

It depends on your needs. If you only need to know whether a number is registered, just select tg registered. If you need to filter recent active users, you must select tg active and specify a window. For the first rescreen, it is recommended to do both to obtain complete dual labels. Afterward, you can streamline according to business focus, e.g., focusing only on activity label refresh.

Q: My number pool exceeds 100,000. Rescreening once takes too long. What can I do?

Large tasks can be submitted in batches, or you can only refresh key regions/genders. KK‑DATA supports up to about 1 million numbers per single task, processed asynchronously with notification via Telegram upon completion. It is recommended to do a full refresh the first time, then gradually refresh by priority (e.g., high‑potential countries) to improve efficiency.

Q: After rescreening, many numbers changed from “active” to “inactive.” Does that mean the number pool quality is poor?

Not necessarily. Many numbers may simply be temporarily inactive (e.g., not active on weekends). It is advisable to observe over 2‑3 rescreening cycles. If they remain inactive continuously, then consider cleaning them. Also check whether your activity window setting is appropriate — choosing 7 days is stricter than 30 days and will mark more numbers as “inactive.” You can test different windows to find the threshold that best fits your business.
