Tutorial on the whole process of screening number service: from number generation to batch screening and export practical guide

For overseas marketing teams, cross-border e-commerce operations and community promotion personnel, screening service is no longer an unfamiliar concept. It helps you quickly find target users who are open, active, and even have gender/age tags in a huge number pool, thereby improving the efficiency of private messaging and reducing ineffective costs. However, many novices tend to fall into the misunderstanding of “taking a bunch of numbers and screening them directly”, ignoring the efficient value of the complete pipeline of number generation → cross-platform screening → data deduplication → result export**. This article takes the KK-DATA platform as an example and walks you step by step through the entire screen number assembly line, allowing you to start from scratch and handle multi-platform number detection and data output at once.

What is the screening service? ——Core tools for foreign trade and overseas customer acquisition

The essence of the number screening service is to batch verify the status and attributes of numbers, for example:

• Is a number registered with Telegram/WhatsApp/Line?
• Has this number been recently active?
• Does the number owner belong to a specific gender or age group?

In the overseas customer acquisition scenario, common needs include: verifying whether the number is open and active before adding followers in Telegram groups; screening out female users before promoting private messages on WhatsApp; Line targeting male groups in the Southeast Asian market; and verifying active accounts in Zalo Vietnam market. These scenarios require a reliable set of screening services to support data cleaning. As a one-stop number screening platform, KK-DATA covers more than ten platforms such as Telegram, WhatsApp, Line, Zalo, and iMessage, and provides a complete tool chain from number generation to final export to help users reduce duplication of work and save detection costs.

Step 1: Number generation - get the number to be screened from zero

Don’t have a ready-made number library? No problem, KK-DATA offers three ways to get free numbers. All generation operations do not consume balances, and fees will be deducted only when screening tasks are submitted.

Method 1: Randomly generated by country/region

Select the target country in the console (supports 240+ countries/regions), and the system automatically generates a random mobile phone number in the country. This approach is suitable for quickly testing a market, validating regional coverage, or preparing initial data for an unfamiliar market.

Method 2: Accurately generate using global number segments

If you know the regional operator’s number segment, you can choose to generate it based on the number segment. For example, select a certain operator’s number range in California, USA, and generate all numbers starting with this number range. This method is suitable for targeted advertising or promotion for users of specific operators.

Method 3: Import existing numbers from CSV or TXT

If you have your own accumulated number files (such as exhibition business cards, historical contact sheets), you can upload them directly. The system will automatically remove duplicates and save them in the database to avoid repeated imports in the future.

Suggestion: After generating or importing numbers, you can first run deduplication in the “Data Deduplication Warehouse” to ensure that no detection quota is wasted.

Step 2: Screening numbers - batch detection of number status and crowd attributes

After the number is ready, enter the core link: submit the number screening task. You need to select Detection Platform, Detection Type in the console, and set parameters (such as active window).

Which social networks does the multi-platform filter cover?

KK-DATA currently supports number detection on the following platforms (specific fields are subject to the console):

Platform	Common detection fields
Telegram	Activation (registration detection), activity (window can be set), gender + age, avatar, tgid
WhatsApp	Open/Active/Gender, wsid
Line	Activated/valid, gender, uid
Zalo	Open/Active/Gender (Vietnam/Southeast Asia focus)
iMessage / iOS	Valid number detection
RCS	Opening detection
Viber	Open/Active
Facebook / Instagram	Account association detection
Binance / LinkedIn	Activate Verification

The detection fields of different platforms vary greatly. Please read the field descriptions on the configuration page carefully before submitting the task. For example, the Telegram filter number can export tgid, which is crucial for subsequent API targeted sending.

How to configure activity and gender detection?

Take Telegram as an example:

1. Select the platform “Telegram” on the task configuration page.
2. Check the “tg activation” detection (basic item).
3. Check the “tg active” detection and set the active window (such as 7 days, 30 days). The smaller the window, the fewer “immediately active” users will be filtered out, but the accuracy will be higher.
4. If you need gender/age data, check the “tg gender” test. The system returns gender (male/female/unknown) and age fields. Note that the age field is estimated based on the behavioral model and is for reference only and cannot be considered an exact value. For example, if you want to target people “about 30 years old”, you can export and filter by age range.

Operation Tips: If you need to do multi-platform detection on the same batch of numbers (for example, check Telegram activation and WhatsApp activity at the same time), it is recommended to create different tasks to manage the export results separately. But please note that duplicate numbers will be identified by the deduplication warehouse, and duplicate numbers will not be deducted.

Step 3: Data Deduplication Warehouse - Avoid duplicate detection and waste of balances

When the number screening task is submitted multiple times, the most feared thing is that the same number is detected repeatedly and the quota is consumed in vain. KK-DATA has a built-in cross-task deduplication warehouse: after each number screening is completed, the system automatically records the detected numbers. When a new task is submitted, the system will automatically filter out these detected numbers and only perform screening on undetected numbers. You can check the deduplication history on the console at any time to confirm which numbers have been detected.

This function is particularly important for long-term operation teams - for example, using the same batch of number libraries to increment numbers every week, without manual deduplication, the system will automatically help you save money.

Step 4: Export results - flexible download in CSV/TXT format

After the screening task is completed (Telegram notification can be bound), you can download the result file on the task details page. Supported formats:

• CSV: Contains all detection fields, suitable for Excel or database processing.
• TXT: Contains only filtered numbers, which is convenient for direct import into the sending tool.

Taking the Telegram filter number as an example, the column names of the exported CSV file may include: 号码, 是否开通, 活跃度得分, 性别, 年龄, 头像URL, tgid, etc. You can use Excel’s filtering function to quickly extract target users who are “open and active + female + age 25-35” for subsequent private message promotion.

Note: The export fields of different platforms are slightly different, please refer to the listing name of the actual downloaded file. If a field is found to be empty, it may be because the number cannot be identified in that dimension (for example, gender detection cannot be determined).

Complete operation checklist for screening service (for novices)

Condensing the above process into a checklist that can be checked one by one, so that you can follow it when you get started:

1. Log in to the console: Go to https://app.kkdata.cc/ to register/log in.
2. Number generation (free): random generation, number segment generation or CSV import, and deduplication and storage.
3. Submit screening task: Select the platform, detection type, active window, etc., confirm the estimated cost and submit.
4. Wait for notification: Bind Telegram notification (or refresh task status regularly), and you will receive a reminder after the task is completed.
5. Data deduplication confirmation: The system has automatically excluded numbers that have been detected in history, no manual operation is required.
6. Export results: Select CSV or TXT format and download to local.
7. Download and use: After processing with Excel or script, import the private message sending tool to start promotion.
