Screen number system practical tutorial: Use batch screen numbers to run through the “upload→detection→export” standard workflow

For overseas teams and cross-border e-commerce operators, how to quickly obtain effective and active target user contact information is an ongoing pain point. Lists of numbers purchased directly or crawled often contain a large number of invalid, unregistered, or even non-existent numbers. Manual detection one by one is not only inefficient, but can also easily lead to account risk control or ban.

Screen number system is designed to solve this pain point. It connects to the verification interface of the target social platform to batch detect whether the number has been registered and active, and can even identify the user’s gender, age and other portrait tags. An efficient and stable batch screening system can help the team accurately screen out available, high-quality customer acquisition leads from massive raw data.

This article will provide an executable Batch Number Screening Tutorial, taking you through the complete standard workflow of “Number Preparation → Task Configuration → Detection and Monitoring → Result Export”. Whether you are performing Telegram community promotion, WhatsApp private message marketing, or Line/Zalo regional customer acquisition, this process can be directly reused.

What is the screening system? Why do you need to screen numbers in batches when acquiring customers overseas?

In the process of acquiring customers overseas, data is fuel, and effective data is high-quality fuel. The core value of the screening system is reflected in the following aspects:

• Multi-platform social number detection: Supports detection of whether the number has accounts on major social platforms such as Telegram, WhatsApp, Line, Zalo, and iMessage.
• Activity and Gender Screening: Not only can it determine “activation”, but it can also identify whether the user of the number is active within a specific time window, as well as the gender registered on the platform (some platforms include fields such as age, avatar, etc.).
• Solve the fundamental pain point: Directly using an unverified number list for group sending or private messaging will lead to a large number of invalid sendings, a waste of time, channel resources and account weight. The screening system allows you to invest 100% of your limited resources and energy into truly effective potential customers.

For teams with limited budgets and pursuing cost-effectiveness, using a per-item screening system that requires no prepaid subscription fees, such as KK-DATA, is undoubtedly the lowest-cost and most efficient option.

Step one: Prepare number source - upload and generate

The first step in any screening workflow is to prepare a list of numbers to be tested. Depending on your data source, there are usually two approaches.

Upload your own number list (CSV/TXT)

If you obtained the number from a trade show list, historical order customers, industry database, or social media crawler, you can upload the file directly.

• Format requirements: One number per line, international format is recommended (e.g. +8613800138000). Supports .csv or .txt files.
• Encoding Notes: When uploading, please ensure that the file encoding is UTF-8 to avoid garbled characters caused by Chinese characters or special symbols.
• File size: A single task supports up to about 1 million numbers. If your list exceeds this amount, it is recommended to upload it in batches or use a script to cut it before submitting.
• Avoid formatting errors: Remove redundant spaces, dashes, brackets and other symbols. A simple format error may cause the number detection to fail.

Use the global number generator to quickly create number segments

If your target market is clear but you lack a ready-made number list, you can directly use the number generator that comes with the screening system to create one.

• Coverage: Supports 240+ countries and regions, and can be randomly generated based on parameters such as country code, number segment prefix, quantity, etc.
• Typical Scenario: Want to expand into the Indonesian market and test WhatsApp users. You can generate a batch of Indonesian numbers starting with +62, and then independently submit the number screening task to check their WhatsApp activation and activity status.
• Special Note: Generating a number is free. Only when you submit the generated numbers to the screening task and complete the test, will the fee be deducted based on the actual number of tests. This provides you with a zero-cost way to prepare your number sources for exploring new markets.

Step 2: Configure screening task—select platform and detection type

After the number source is ready, the next step is to configure the number screening task. This is the core link of the entire workflow and directly affects the final data quality.

Multi-platform screens: Telegram / WhatsApp / Line, etc.

• Platform comparison:
  • Telegram (TG): Suitable for community operations, channel promotion, and encrypted communication user acquisition. Can detect activation, activity, gender and TG ID.
  • WhatsApp (WA): One of the communication software with the largest number of users in the world, suitable for private message marketing and customer follow-up. Can detect activation, activity and gender.
  • Line: Mainstream applications in Japan, Taiwan, and Southeast Asia markets, suitable for localized customer acquisition. Can detect activation and gender.
  • Zalo: An application that occupies an absolute monopoly in Vietnam, targeting customers in Southeast Asia.
  • iOS / iMessage & RCS: Detect whether the number activates iMessage or RCS (Rich Media Communication), suitable for accurately reaching Apple/Android users.
• Combination configuration: You can select multiple platforms at the same time in one task, and the system will detect the status of the same number on each platform one by one. This is equivalent to one upload and multiple verifications, which greatly improves efficiency.

Detailed explanation of detection types: activated, active, gender recognition

• Activation (Registration Test): Refers to whether the number has registered an account on the corresponding platform.
• Active: Refers to whether the number has logged in or been active within the set time window. You can customize the active window (such as 7 days, 30 days, 90 days) to filter out high-value users who have been active recently.
• Gender Identification: Determine the gender in social media registration information through algorithms. It should be noted that, for example, the “tg 30-year-old data” provided by the platform is filtered and interpreted through the age field in the test results, and is not an independent age detection product. This helps you build age-specific age groups, but it doesn’t achieve ID-level accuracy.

Step 3: Start detecting and monitoring task progress

After the configuration is complete, click Submit task. You can view the status of each task in real time in the “Task List” of the console.

• Task Status: Common statuses include “queuing”, “detecting”, “completed”, and “failed”.
• Notification method: After the task is completed, the system can send notifications through your bound Telegram account, so that you don’t have to stare at the screen all the time.
• Concurrency Strategy: You can submit multiple tasks at the same time, but the system will queue them based on server resources. For large tasks (such as detecting 500,000 items at a time), it is recommended to reserve sufficient processing time.

Step 4: Export results—export available data on demand

When the task status changes to “Completed”, you can export the results file.

• Format Selection: Supports exporting to .csv or .txt files.
• Field filtering: When exporting, you can filter useful data by checking fields. For example, if you only want numbers with “Telegram enabled and active”, you can check only “Telegram enabled = Yes” and “Telegram active = Yes” in the filter criteria.
• Cross-task deduplication: KK-DATA has built-in data deduplication warehouse function. When you submit a new number screening task, the platform will automatically compare the numbers that have been detected in historical tasks to avoid repeated testing and help you save your balance.

FAQ

**Q: How many numbers can be detected at most in one number screening task? **

Answer: The maximum number of single tasks is about 1 million. If your number list exceeds this amount, it is recommended to submit it in batches or use our manual customer service to assist.

**Q: What fields are included in the filter number results? **

Answer: Different platforms and different detection types return different fields. Usually includes: original number, platform activation status, active status, gender, age (for some platforms), platform unique ID (such as tgid/wsid/uid), etc. The specific column names are based on what you see when exporting on the console.

**Q: How accurate is gender recognition? **

Answer: Gender recognition is based on public information filled in by users on social media (such as the gender option in the profile). The accuracy is high, but it cannot be 100%. It is recommended to use it as an auxiliary reference for crowd targeting, rather than the only screening criterion.

**Q: I have already recharged, why is it prompted that the balance is insufficient when submitting a task? **

Answer: The system will verify the balance and estimated expenses before submitting the task. If the task you submit requires detecting 1 million numbers, the estimated cost is X, and your balance is lower than X, you cannot submit it. Please make sure you have enough balance after recharging.

**Q: Can the task be canceled after it is submitted? **

Answer: Once a task is submitted and entered into the system queue or detection, it usually cannot be canceled. If the task status is “queuing”, you can contact customer service to try to cancel. It is recommended to double check the configuration and estimated cost before submitting.
