One-stop guide to number screening services: a complete customer acquisition map from number generation to multi-platform screening

In overseas marketing, customer acquisition efficiency and data quality directly determine the input-output ratio. When your team has a batch of mobile phone numbers and wants to accurately reach potential customers on Telegram, WhatsApp, Line or Zalo, Screening Service becomes an indispensable infrastructure. It is not a simple number verification tool, but a complete data pipeline that supports batch customer acquisition: from number generation, multi-platform detection to data deduplication, every step can help you save time and costs. This article will draw a clear “screening service keyword map” for you to help the team quickly build an efficient customer acquisition pipeline.

What is the screening service? How does it help overseas teams reduce costs and increase efficiency?

The number screening service, as the name suggests, is a system for automated verification and screening of massive mobile phone numbers. Core capabilities include: detecting whether a number is registered on a social platform (such as Telegram/WhatsApp), determining user active status, identifying gender and age range, etc. For B2B SaaS customer acquisition and cross-border e-commerce promotion teams, its value is very direct:

• Avoid invalid sending: Sending messages to unregistered numbers will waste quota and be marked as harassment. After screening, only valid numbers will be pushed, and the reach rate will increase by more than 80%.
• Precise targeting of people: Filter by fields such as gender and activity level to focus marketing resources on high-intention users.
• Reduce operating costs: Under the item-by-item billing mode, only one fee will be deducted for each item tested, reducing duplication of work.

Simply put, the screening service is the “data quality inspector” of the overseas team, allowing every marketing investment to be spent on the cutting edge.

What are the core functions of the screening service? A “Keyword Map” to get you started

In order to allow new users to quickly understand what the screening service can do, I compiled a functional keyword map covering mainstream scenarios:

Function modules	Sub-capabilities	Applicable scenarios
Multi-platform social screening account	Telegram/WhatsApp/Line/Zalo/iMessage/RCS/Viber/Facebook/Binance, etc.	Verify the registration, activity, and gender of the number on each platform
Number generation	240+ countries/regions randomly generated, number segment generated, CSV custom import	Batch generated numbers to be tested when there is no number source
Data deduplication warehouse	Automatic deduplication across tasks to avoid repeated detection	Prevent balance waste in long-term operations
The remaining balance is billed on a per-item basis	No subscription package, fees will be deducted after the task is completed	Use on demand, flexibly control the budget

The following is an introduction to the two core capabilities.

Multi-platform social screening: verify activation, activity, gender and other fields

The fields that each platform can detect are slightly different. Please refer to the actual export results of the console, but they basically cover the following directions:

• Telegram detection:
  • tg 开通: Determine whether the number has been registered with Telegram.
  • tg 活跃: You can specify an active window (such as online within 7 days/30 days) to filter recent interactive users.
  • tg 性别: Contains gender and age fields (age is calculated based on public data models, such as the “about 30 years old” interval, non-ID card level accuracy).
  • Can be exported tgid for subsequent secondary operations of own systems.
• WhatsApp Detection: fields such as activation, activity, gender, etc. Pay attention to the detection frequency limit to avoid being blocked.
• Line detection: Line activated, valid, gender (can target male/female), export uid.
• Zalo Test: For Vietnam/Southeast Asia market, supports activation, activity, and gender detection.
• Other platforms: iOS/iMessage blue number detection, iMessage validity, Viber/Facebook, etc., choose as needed.

Global number generation and screening closed loop

Many teams do not have ready-made numbers at first, KK-DATA provides free number generation function:

• Randomly generated by country (240+ countries supported).
• Generated by number segment (such as US +1 number segment).
• Upload a custom CSV file as a library of alternative numbers.

After generation, directly select the number list to initiate the screening task, forming a complete pipeline of “Generate → Filter → Export”**. There is no deduction for the generation itself, and the balance will be deducted only when the detection task is completed.

How to use the number screening service to verify the validity and activity of Telegram numbers in batches?

The following is a standard operating procedure, taking the Telegram filter number as an example:

1. Log in to the console: Visit https://app.kkdata.cc/ and deposit USDT (TRC20) to obtain available balance.
2. Create screen number task: Select “Telegram screen number” and upload the number file (supports CSV/TXT, up to about 1 million at a time).
3. Select detection type:
   • Just confirm whether to register → check “Activate”.
   • Want to find recent active users → Check “Active” and set the active window (such as 7 days).
   • Need to target gender and age → Check “Gender”, the results will include gender and age fields.
4. View estimated fees: The page will display the estimated deduction amount for this task (calculated based on the real-time unit price of each platform, see the console for details).
5. Submit task: After confirmation, the system will start detection, and will be notified through the Telegram robot after completion.
6. Export results: Select CSV or TXT format to export. Fields include number, registration status, activity level, gender, age direction, tgid, etc.

Common combination scenarios of Telegram screen numbers

• Only for group messaging: Just activate the status to avoid sending to unregistered numbers.
• Community Recruitment: Active users are required, select “Active” and specify the window (such as updates within 30 days).
• Gender-targeted promotion: For example, to promote female-oriented products, select “Gender” and export the female field, and refer to the age range (about 20–30 years old, etc.) for segmentation.

What is the use of exporting tgid? How to use tgid for secondary operations?

tgid is a unique numeric identifier for a Telegram user. After exporting, you can combine it with your own scripts or third-party tools:

• Send messages to specific tgid users in batches (subject to Telegram rules to avoid being restricted).
• Pull in a channel or group (via bot invitation logic).
• Used for subsequent interactions between its own CRM system and users.

Note: When using tgid for active marketing, please be sure to comply with the privacy regulations and platform terms of service in the user’s region.

What are the differences between WhatsApp, Line, and Zalo screen numbers? How to choose?

The distribution of users on different platforms is obviously different. Choosing the appropriate filter direction can get twice the result with half the effort.

Platform	Main markets	Supported detection fields (subject to the console)	Notes
WhatsApp	Global (especially Southeast Asia and Latin America)	Activation, activity, gender	Frequent detection may trigger account restrictions, it is recommended to control the number of times
Line	Japan, Taiwan, Thailand	Open, valid, gender (can target men)	Gender detection is very effective for targeting Japanese/Taiwanese male users
Zalo	Vietnam	Open, active, gender	An important entrance to acquire customers in the Vietnamese market, activity detection is very valuable

Choose a strategy: If the target market is Japan/Taiwan → Priority Line; Vietnam → Zalo; Global → WhatsApp or Telegram. It can also be used in a mixed manner. Numbers are generated first and then screened across platforms simultaneously to maximize data utilization.

Why are “number generation” and “number deduplication” important in the number screening service?

These two functions may seem basic, but in actual operations they can help you save a lot of budget and time.

• Number Generation: When your target market lacks local number samples, quickly create a candidate list with the country/number segment generator. The generation is free, but only the testing fee will be deducted from the screening results. It is recommended to use number segments to generate small batches for testing first, and then generate large-scale production after confirming the market quality.
• Number deduplication warehouse: Many teams will submit the same batch of numbers repeatedly (for example, numbers screened a month ago are uploaded again), resulting in repeated deductions. The platform has a built-in deduplication function that automatically compares historical detected numbers every time a new task is submitted, eliminates duplicates, and ensures that only new numbers are billed.

Best Practice: After each export of screen number results, retain tgid/wsid/uid to the local database. Before importing the number file next time, use the deduplication warehouse to conduct a global comparison to avoid repeated submissions.

How to evaluate the cost performance and billing model of the screening service?

KK-DATA adopts a zero subscription package and pay-per-item model, which is very suitable for teams with volatile needs:

• Recharge method: USDT (TRC20), the minimum is about 50 USDT, the balance will be updated immediately upon arrival.
• Deduction timing: After the number screening task is completed, the corresponding fee will be deducted from the balance. No fees will be deducted if the task is not completed.
• Insufficient balance: New tasks cannot be submitted and need to be recharged first.
• Unit price reference: The unit price is different for different platforms (Telegram / WhatsApp / iMessage / Line / Zalo, etc.) and different detection types (activated / active / gender). For the specific amount** please log in to the console to check the estimated cost** when creating a task, or visit the official website https://kkdata.cc/billing/ to get the latest price list. This article is not making up numbers.

Cost-performance analysis: For small and medium-sized teams that perform 100,000-1 million tests per month, the billing model is more flexible than fixed subscriptions. No idle credit is wasted, you pay for what you use, and long-term costs are controllable.

What anti-fraud and compliance matters need to be paid attention to when using the screening service?

1. Official customer service channel: The official customer service of the platform can only be contacted through the two-way contact robot https://t.me/kkdata_robot or the customer service account @kkdata_robot. Any other account that actively contacts you to ask for your password, balance, or verification code is a scam.
2. Compliant use: The screened results are used for legitimate marketing. You are not allowed to send spam messages, harassing messages, or violate the usage agreement of each platform (such as adding a large number of strangers or spamming advertisements). Violations may result in the account being banned from the platform.
3. Anti-fraud query: The platform provides official account verification methods in the document, and it is recommended to verify before use.

Filter service practice: a complete customer acquisition data pipeline example

Scenario: An e-commerce team wants to promote a new product to the German market, and the target users are male users who are active on Telegram.

1. Generate Number: Select “Number Generation” on the console, select Germany as the country, and randomly generate 10,000 numbers in the number segment. It’s free and available immediately.
2. Filter Telegram users who are active and male: Create a Telegram number screening task, upload the above number file, and check both “Active” (window set for 7 days) and “Gender” for the detection type. Check the estimated fees before submitting to make sure you have sufficient balance.
3. Waiting for completion: After about 15–30 minutes, the task is completed and the system sends a notification through the Telegram bot.
4. Export data: Export CSV, filter out users with “tg_active=yes” and “gender=male”, get about 2,000 high-value numbers, and export tgid at the same time.
5. Duplication Warehouse: Import this batch of tgid into the local library. Next time a new number is generated, it must go through the Duplication Warehouse before submitting the screening number to avoid repeated detection.
6. Next step marketing: Use tgid to call Telegram Bot API to send private messages (subject to platform rules) or to join brand groups.

The entire process, from number generation to exporting high-intention users, takes less than 2 hours. The total detection cost is estimated to be about tens of USDT based on the unit price of the platform, which is far lower than the ineffective cost caused by blind mass messaging.

FAQ

**Q: The screening service is billed on a per-item basis. What is the price per item? ** Answer: The unit prices for different platforms and detection types (such as Telegram activation, WhatsApp activity, Line gender) are different and may be adjusted dynamically. Please log in to the console to view the real-time estimated costs when creating a task, or visit the official website billing page https://kkdata.cc/billing/.

**Q: Is number generation free? How many entries can be generated at most? ** Answer: Yes, the global number generation function is free to use and supports 240+ countries/regions, custom number segments, and CSV import. There is no hard upper limit for the number of items generated at a time, but it is recommended that the number of items generated at a time should not exceed 1 million to avoid excessive time consuming for subsequent screening.

**Q: Is the “Age” field in the test results accurate? Can it be accurate to the ID card level? ** Answer: No. The age field in gender detection is an age range (such as about 30 years old) calculated based on a public data model. It is not an accurate date of birth. It is only for crowd orientation reference and must not be used in compliance scenarios that require precise age.

**Q: How to prevent the same number from being repeatedly detected and wasting balance? ** Answer: The platform provides a data deduplication warehouse. When each screening task is submitted, the system will automatically compare the historical detected numbers, eliminate duplicates, and ensure that each detection is a new number. It is recommended to retain the tgid/wsid after each export for local deduplication.

**Q: Can the balance be refunded? What should I do if the recharge fails? ** Answer: The deposited USDT balance can only be used to deduct fees for platform number screening tasks, and cannot be withdrawn or refunded. If the recharge fails, please contact the official two-way customer service https://t.me/kkdata_robot to verify the blockchain hash, which usually takes no more than 30 minutes.
