Global number generation and base material screening standard tutorial: one-stop assembly line from batch generation to precise screening number

In the actual practice of acquiring customers overseas, we often encounter such scenarios: we have a large number of potential mobile phone numbers, but we don’t know which ones are actually activated on Telegram or WhatsApp; or we want to target a certain country for targeted promotion, but we lack the source of local original numbers. Base Material Screening is a standard operating procedure created to solve these two problems - first obtain a large number of original numbers (base materials) through Global Number Generation, and then extract high-value target users from them through batch screening of numbers. This article will take you step by step to build a complete pipeline from generation to screening.

What is base material screening? Why is it important to acquire customers overseas?

Basic screening is a commonly used term in the field of overseas marketing and community operations. Its core meaning is: from a large number of unfiltered original mobile phone numbers, use technical means to detect and filter out the numbers that truly meet your customer acquisition goals. These goals may include:

• Activation status: The number has been registered on Telegram / WhatsApp / Line and other platforms;
• Activity: The number has been used in the recent period;
• Gender/Age: The gender, age group and other attributes of the user behind the number (limited to the fields provided by the platform).

If you compare going out to sea to get customers to fishing, the original number is the entire pond, and the bottom material screening is to help you catch the fattest fish from the pond. Many of the numbers that have not been screened are empty, silent or non-target groups. Direct promotion is not only inefficient, but may also lead to account risk control.

An efficient base material screening process usually includes two indispensable steps: First obtain the original base material for free through the number generation tool, Then batch testing through the screening number platform. Below we take KK-DATA as an example to explain the specific operations in detail.

Global number generation: Two ways to get massive original numbers for free

KK-DATA provides two global number generation methods, covering 240+ countries and regions, all free of charge, and there is no charge for generation. You can find this module on official website homepage or in the console.

Method 1: Randomly generate numbers by country/region

It is suitable for scenarios where you do not have your own number at all and need to build a database from scratch. The operation is very simple:

1. Log in to Application Console and enter the “Global Number Generation” module.
2. Select the target country (such as Indonesia, Brazil, Mexico, etc.), and the system will automatically load the number segment format of that country.
3. Set the number of generated items (up to about 1 million at a time).
4. You can choose to specify the beginning of the number segment (for example, only generate Indonesian numbers starting with 62).
5. Click Generate, select the export format (CSV or TXT), and download with one click.

The generated number conforms to the country’s number segment format, but it does not mean that the number actually exists or has been registered. They are just raw base materials, and the next step needs to be verified by the screen number function.

Method 2: Customized number segment CSV import

If you already have some numbers (such as CSV files collected from other channels, or a certain number segment is known), you can directly import it into the system to complement the random generation.

• Select “Import number segment” or “Upload CSV” on the “Global Number Generation” page.
• The file format is generally a pure number sequence (can include international area codes).
• The system will identify and fill the number segment template and generate the specified number of numbers.

This method is suitable for: you already have some basic data and want to expand more numbers in the same number range; or you need to dig deep into specific number ranges (such as some operator-specific number ranges).

Complete pipeline for base material screening: from global number generation to precise screening numbers

After generating the original number, you can enter the screening number pipeline. Below is the complete four-step process.

Step 1: Generate numbers → Import screening task

From the “Number Generation” page, import the generated numbers into the “Number Filter” module with one click, or directly upload an existing CSV/TXT number file. The system supports batch import, with a maximum of about 1 million items at a time.

Step 2: Select platform and detection type

Based on your customer acquisition goals, choose the platform to be tested:

Platform	Common detection types	Remarks
Telegram	Open, active (window can be specified), gender (including age/avatar/tgid)	When detecting tg gender, the age field is model estimation
WhatsApp	Activation, active, gender (including wsid)	Active window can be customized
Line	Open, valid, gender (including uid)	Suitable for Japan/Taiwan/Southeast Asia market
Zalo	Open, active, gender	The first choice in Vietnam market
iMessage	Valid number detection	Suitable for iOS user targeting

The detection fields supported by each platform are different, please refer to the console export for details. It is recommended to select the intersection of 2-3 platforms for combined screening (for example: detect through Telegram and WhatsApp at the same time to get active numbers).

Step 3: Submit the task and view the estimated cost

After selecting the platform and detection type, click “Submit Task”. The system will automatically calculate the estimated deduction amount for this task (see the real-time price on the console for details). Submit after confirmation. Please ensure that the account balance is sufficient; if the balance is insufficient, you need to recharge USDT (TRC20) into the account first, with a minimum of about 50 USDT. Once the task is completed, receive notifications via Telegram.

Step 4: Export filtering results (CSV/TXT)

After the task is executed, enter the “Task Management” page to view the results. Select the number that meets your criteria (such as “Telegram Active + Male”) and click Export.

The export file contains rich fields:

• Platform ID (e.g. tgid, wsid, uid)
• Open status
• Active status (including detection time window)
• Gender (if tested)
• Age range (if tested)
• Avatar URL (supported by some platforms)

Fields vary by platform and detection type, and are subject to export results.

Differences in the application of base material screening on different platforms: Telegram, WhatsApp, Line, Zalo

The differences in screening capabilities of different platforms directly affect your choice of customer acquisition strategy:

• Telegram: The advantage is that activity detection can specify a window (such as 7 days, 30 days), and gender detection can provide an age field, which is suitable for targeting people around 30 years old. The exported tgid can be used for further portrait analysis.
• WhatsApp: Through wsid detection, active window customization, suitable for overseas markets where instant messaging is the main focus (such as India, Brazil).
• Line: Strong gender detection capability, can target males or females, uid export is suitable for operation in conjunction with Line groups.
• Zalo: Exclusive to the Vietnamese market, activation and active testing are the immediate requirements for acquiring customers in this region.

According to the target country and customer acquisition method, selective combination of multi-platform screening numbers can greatly improve the accuracy of delivery.

How to avoid repeated testing and waste of balance during the base material screening process?

Fees will be deducted each time the number is screened. If you test the same numbers over and over again, your balance will be wasted. KK-DATA has a built-in data deduplication warehouse function to automatically solve this problem:

• When you submit a number screening task, the system will compare it with the number database that has been detected in history.
• For numbers that have been tested and the results have not expired, the system will automatically skip them without charging.
• You can manage/view historical detection records in the console.

Recommended practice: Before screening numbers each time, first import all historical detected numbers through the data deduplication warehouse. This way there will be no additional charges if there are duplicates in the number list.

Best practices and precautions for base material screening

1. Small batch testing first: Before officially screening numbers on a large scale, test the detection type and format with hundreds of numbers to confirm that the exported fields meet the requirements before increasing the volume.
2. Prioritize testing of high-value platforms: If your main customer acquisition channel is Telegram, you can only do TG testing. Do not check all platforms at the same time to avoid unnecessary deductions.
3. Pay attention to the accuracy of the gender field: The gender detection results of Telegram/WhatsApp are based on a probability model, which is suitable for reference for targeted delivery, but cannot be regarded as absolutely accurate. In particular, the “tg 30-year-old data” field can only be used to filter people of the appropriate age group, and should not be used in scenarios that require precise identity verification.
4. Make good use of data deduplication: After each number screening, add the exported number to the deduplication warehouse, and ensure that “automatic deduplication” is checked when submitting a new task.
5. Select the export format as needed: CSV is suitable for subsequent processing (such as Excel, API docking), and TXT is suitable for importing into Telegram/WhatsApp group messaging tools.

FAQ

**Q: How is the “activity” test in base material screening defined? ** Answer: Activity refers to the usage behavior of the number within the specified time window (such as Telegram/WhatsApp login, sending and receiving messages, etc.). The detection window can be selected by the user (such as 7 days, 30 days, etc.), and the system determines whether it is active based on platform signals.

**Q: Do the numbers generated by Global Numbers actually exist? ** Answer: The generated number conforms to the corresponding country number segment format, but may not have been registered. After generation, you need to check its activation status and activity through the screening function. The generation itself is free, and the detection is billed on a per-item basis.

**Q: How many numbers can the bottom material screening task support at one time? ** Answer: A single task supports up to about 1 million numbers. If the amount of numbers exceeds, it is recommended to submit them in batches; the data deduplication warehouse will automatically identify the detected numbers to avoid repeated deductions.

**Q: What are the differences in the detection result fields of different platforms (Telegram vs WhatsApp)? ** Answer: The fields are subject to console export. For example, Telegram supports tg activation, tg activity, and gender (including age, avatar, and tgid); WhatsApp supports activation, activity, and gender (including wsid); Line supports activation, gender (including uid). Please refer to the document https://docs.kkdata.cc/。 for details.

**Q: I have forgotten whether I have detected certain numbers before, how to avoid repeated deductions? ** Answer: KK-DATA has a built-in data deduplication warehouse. When submitting a task, the system will automatically compare the historical detected numbers and skip duplicate items without charge. It is recommended to import the historical number database to complete deduplication before each number screening.
