Complete guide to number screening: Practical process from Bing search to batch verification (including Telegram/WhatsApp/Line)

In overseas marketing, do you often encounter this problem: you have a batch of mobile phone numbers on hand, but you can’t tell which ones are registered on Telegram or WhatsApp, which ones are active, and which ones are male or female? When you search for “number filtering” on Bing, you are probably trying to find an efficient, low-cost batch verification solution. This article will break down the core logic of number screening for you, and provide a complete guide from Bing search to actual operation to help you quickly target precise customers.

What is number screening? Why is it needed to acquire customers overseas?

Number screening, simply put, is to use technical means to batch detect the status of mobile phone numbers - whether they are registered on a certain social platform, whether they are active, and even bring out attributes such as gender, age, and avatar. For B2B SaaS, cross-border e-commerce, and independent website promotion teams, this is almost a “required course” before acquiring customers. The reason is simple:

• Reduce the harassment rate: Directly sending mass marketing information to unregistered numbers is a waste of costs and may lead to complaints.
• Increase conversion rate: Active users are more likely to view messages. Gender targeting can help you make personalized contacts in private messages and community operations.
• Data Cleaning: Lists of numbers sourced or scraped from third parties are often spotty, leaving “real gold” behind after filtering.

When you search for “number screening” from Bing, what you are actually asking is: “Is there a tool that can quickly verify the true status of tens of thousands or even hundreds of thousands of numbers on Telegram, WhatsApp, Line and other platforms?” The answer is yes - professional number screening platforms like KK-DATA were born for this purpose.

What common problems will you encounter when searching for “number filtering” on Bing?

Are “Number filtering” and “Number generation” the same?

**no the same. ** Number generation refers to randomly creating numbers (such as generating numbers that match the number range for 240+ countries/regions). These numbers may have never been used; while number filtering is to verify the list of numbers you already have. The two can be used in combination on KK-DATA: first generate a global number for free, and then conduct screen code detection on the generated number, forming a complete pipeline of “generate → filter → export”.

What fields are included in the filter results?

The fields returned by different platforms and detection types are different. Taking Telegram screen number as an example, typical fields include:

• Activation Status (Yes/No Registration)
• Active period (can specify the last 1 day, 7 days, 30 days, etc.)
• Gender (Male/Female/Unknown)
• Age (can be used to screen people around 30 years old)
• tgid (Telegram unique ID)

For platforms such as WhatsApp, Line, Zalo, etc., the fields are similar but slightly different. Please refer to the real-time results of the KK-DATA console for the specific export content, because the platform API will be constantly updated and the tools will be expanded accordingly.

How to use KK-DATA to filter numbers? (5-step practical process)

Step 1: Register, log in and recharge USDT

Visit KK-DATA Application Console, register an account and log in. The platform adopts a per-item deduction model and does not require a subscription package. You need to recharge your balance first: use USDT (TRC20) to transfer, the minimum is about 50 USDT, and the balance will be automatically updated after arrival. You can create tasks after recharging.

Step 2: Prepare numbers to be screened (generate or import)

You have two ways to get the number:

1. Global number generation (free): Select the target country (240+ optional) and number segment on the console to generate numbers in batches. This feature is completely free.
2. Custom number import: Upload CSV file, support custom number segments. You can also import from front-end user registration data and lists provided by partners.

Step 3: Create a screening task and select the detection type

Click “Create Task” and follow these steps:

• Select the target platform (Telegram/WhatsApp/Line/Zalo/iMessage/RCS etc.)
• Check the required detection dimensions (activated, active, gender, etc.). Some platforms such as Telegram support customizing the activity window (such as “active in the last 7 days”).
• The system will automatically calculate the estimated deduction and submit it after confirmation.

Note: A single task can handle up to about 1 million numbers. If you need to test a larger quantity, it is recommended to submit in batches.

Step 4: Wait for the task to complete and receive notifications

After the task is submitted, it will enter the queue. You can view the progress in real time on the console. Turn on Telegram notification (bind your TG account in settings), and you will receive a message immediately when the task is completed, without having to stay in front of the computer all the time.

Step 5: Export filtering results (CSV/TXT)

After the task is completed, export the results. Support CSV, TXT format. The exported data can be directly used for community import, private message group sending or further data analysis.

Differences and applicable scenarios of screen numbers on different platforms

Platform	Main detection dimensions	Common application scenarios
Telegram	Open, active (custom window), gender, age, tgid	Southeast Asia, Eastern Europe, Latin America community operations, 1v1 private message
WhatsApp	Open, active, gender	WhatsApp marketing in Europe, America, Southeast Asia, and the Middle East
Line	Open, valid, gender (uid export)	Line community marketing in Taiwan, Thailand, and Japan
Zalo	Open, active, gender	Localized customer acquisition in Vietnam
iMessage / iOS	Blue bubble/device detection, iMessage valid number	Precisely reaching North American Apple users

Telegram filter number: tg active, tg gender and tgid export

Telegram is a popular platform for overseas marketing. You can use KK-DATA to detect whether the number has activated TG, the most recent active time window (such as accounts active in the last 1 week - this is a golden group with high conversion), and obtain the gender and age fields. tg 30-year-old data refers to the age field in the gender detection results, which can be used to screen people around 30 years old, and is suitable for promotion to young and middle-aged users.

WhatsApp Screen Number: Open/Active/Gender Detection

WhatsApp has extremely high penetration rates in Europe, America, Southeast Asia, India and other regions. When filtering numbers, enabling detection can filter out numbers that don’t cost money; activity detection helps you locate users who have been online in the past 7 days or 30 days; gender targeting allows you to push content based on male/female distinctions.

Line and Zalo filters: localization for East Asia/Southeast Asia

Line is a national-level application in Taiwan, Japan, and Thailand. In addition to the activation status, the screening results can also export Line uid to facilitate subsequent accurate access through Line’s official API or community tools. Zalo occupies an absolutely dominant position in Vietnam, and activation + activity + gender are the standard configuration for localized customer acquisition.

How to avoid repeated detection? Tips for using data deduplication warehouse

Users often report that after the first screening, the same batch of numbers are used for testing again a few days later, resulting in repeated deductions. KK-DATA provides the Data Deduplication Warehouse function - you only need to import the numbers to be screened into the deduplication warehouse, and the system will automatically compare the historical measured numbers and mark which ones have been tested to avoid repeated submissions.

Usage process: Enter the “Duplicate Warehouse” of the console → Upload CSV → The system returns the tested and untested lists → Create a screening task only for untested numbers. This can save up to 30% to 50% of screen size costs.

Efficiency optimization suggestions for number screening (batch tasks and notifications)

• The upper limit of a single task is about 1 million items: If your list exceeds 1 million, it can be divided into multiple tasks less than 1 million by number segment or randomly and submitted in parallel. KK-DATA supports running multiple tasks at the same time without affecting each other.
• Turn on Telegram notification: As mentioned above, after binding TG and turning on “Task Completion Notification” in the settings, you can receive result push on your mobile phone without staring at the console.
• Use number segment generation instead of full import: If you only lack the number of a specific number segment, directly use the global number generation function to obtain the local number segment of the target country for free, and then filter the numbers accordingly. This is more controllable than paying for a list.
