Too many Telegram numbers and unsure which ones are usable? Batch filtering helps you find valid accounts all at once.

When operating a Telegram account, having a large number of phone numbers but being unable to distinguish between good and bad ones can easily lead to wasted resources. Telegram batch filtering can quickly eliminate invalid numbers, and effective batch filtering is key to improving the accuracy of operations. Invalid numbers not only cause messages to go unanswered but can also increase account risk; pre-emptive batch filtering ensures that every operational action is valuable.

What risks can number validity verification avoid?

Number validity verification is not simply about checking whether the call can be connected, but rather about determining:
  • Has this number actually been registered as a Telegram account?
  • Is the account in normal use, or has it been banned or cancelled?
  • Does the phone number's location match the account's frequently used region?
If you skip the validity check and operate directly, you may encounter these problems:
  • The failure rate of bulk message sending soared, and the account was deemed abnormal by the platform.
  • Using virtual or abandoned accounts can lead to restrictions being imposed on the main account as well.
  • Investing resources in invalid numbers is a waste of time and operating budget.
  • Confusing valid phone number data makes it impossible to accurately assess operational effectiveness.
The core of Telegram's bulk account screening is to first screen out valid accounts to lay a solid foundation for subsequent operations. ITG's full-domain screening can accurately complete this core step.

What operational challenges can active status screening solve?

Activity status screening doesn't just look at whether the account exists, but rather determines:
  • How long ago was the user last logged into Telegram?
  • Is the account classified as highly active, moderately active, or low active?
  • Is it better to push messages directly, or is it necessary to wake up and activate the device first?
If you blindly operate without considering user activity, these problems will occur:
  • Sending activity notifications to accounts that haven't logged in for a long time resulted in no response whatsoever.
  • Pushing high-value content to inactive accounts results in low conversion rates.
  • Frequently disturbing highly active users can lead to being blocked or reported.
  • Unified operation regardless of activity level makes it difficult to find optimization direction.
To maximize the value of different accounts, it is necessary to operate them in tiers based on their activity levels. This also requires data support from Telegram's batch screening of accounts.

What redundancy issues can duplicate number screening solve?

Duplicate number screening is not simply about removing duplicates, but about making judgments:
  • Are there any duplicate Telegram accounts in the list of phone numbers?
  • Do duplicate phone numbers belong to the same user and cause spam messages?
  • Will duplicate data interfere with the statistical analysis of operational effectiveness?
If you ignore duplicate numbers and perform batch operations directly, you will encounter these problems:
  • The same account received messages multiple times, which angered users and led to reports.
  • Duplicate data leads to wasted operational budgets and inflated actual reach numbers.
  • Bias occurred when analyzing interaction data, making it impossible to accurately optimize strategies.
  • Duplicate phone numbers occupy push notification slots, squeezing out opportunities to reach valid users.
Batch filtering of Telegram accounts requires simultaneous cleanup of duplicate data to allow operational resources to focus on effective targets and improve overall reach quality.

How can I use ITG global filtering to achieve automatic number filtering?

ITG's global filtering feature allows for fully automated filtering of Telegram numbers. It's simple to use with no complicated setup. The specific steps are as follows:
  • Batch import numbers: Import the list of numbers to be filtered into the tool all at once, eliminating the need to manually enter each number one by one.
  • Automatic multi-dimensional verification: The tool simultaneously verifies account registration status, activity level, and operating environment security.
  • Intelligent removal of invalid numbers: Automatically filters out invalid numbers such as empty numbers, banned numbers, and long-term inactive numbers according to preset conditions.
  • Export results by category: Valid phone numbers are sorted by activity level and region, and a report is generated that can be directly connected to subsequent operations.
This tool supports multi-threaded operation, which can significantly save manual verification time and ensure screening accuracy, solving the problem of complicated and difficult-to-identify numbers from the source.

Conclusion

Bulk number filtering on Telegram is a key step in improving operational efficiency. Leveraging ITG's comprehensive filtering to precisely eliminate invalid numbers allows operations to directly target their objectives. This saves resources and reduces account risk, ensuring every investment yields a return.
