Line activation data check list: Precise screening guide before the event (2025 version)

In overseas marketing, Line is a common social platform for users in Japan, Taiwan, and Southeast Asia (Thailand, Indonesia, etc.). Whether it is B2B customer acquisition, community operation or private message promotion, checking the Line activation data of the target number before the event - that is, verifying whether the number has been registered for Line - is a key step to avoid invalid delivery and improve ROI. However, it takes many teams several days to manually verify thousands of numbers, and dimensions such as gender and activity cannot be obtained. This article provides an implementable Line activation data checklist, covering number preparation, screen number setting, fee confirmation, result export and best practices to help you efficiently screen effective Line users in 2025.

Why is Line activation data checklist required before the event?

Without a checklist, you may encounter:

• There are a large number of numbers in the number list that are not registered with Line, and the success rate of private messages is extremely low.
• Repeated detection of the same number wastes budget.
• Unable to target gender (such as only pushing to male users), resulting in low conversion rate.
• Ignore the activity verification and find out that the user is already offline after sending.

A reusable checklist can help you:

• Reduce invalid requests: Only initiate contact activities for numbers that have opened Line.
• Cost Control: Under the itemized billing model, deduplication and pre-screening can significantly reduce the total cost.
• Improve operational efficiency: Automated screening replaces manual verification one by one, and the team can focus on strategy rather than physical work.

Line activation data The core value in this scenario is to quickly distinguish between “reachable users” and “invalid numbers”. Next, we will start from the first step.

Checklist Step 1: Prepare a list of numbers to be tested

Number quality directly affects the screening effect and cost. It is recommended to prepare from the following sources:

Number source 1: own customer or target country number segment

• Export customer mobile phone numbers from CRM, historical activities, and registration forms.
• If you target the Japanese market, you can collect Japanese +81 segments (such as starting with 080, 090, 070).
• Note: Be sure to clean the number format and unify it into an international format (such as +818012345678), otherwise the number screening platform may fail to recognize it.

Number source two: Use KK-DATA global number generation module (free)

KK-DATA provides global number generation function, supporting random generation, number segment generation, and custom number segment CSV import in 240+ countries/regions. This module is completely free. You can use it to quickly generate a list of numbers for your target market and then enter the number screening process.

• Randomly generated: Specify the country code and quantity, and the system will randomly generate the number under the valid number range.
• Number segment generation: Enter the country code and prefix (such as 8123) to generate consecutive numbers.
• Custom Import: Upload a CSV file and the platform will automatically verify the format.

After generation, it is recommended to perform data deduplication on your own historical data: KK-DATA’s data deduplication warehouse can automatically merge duplicate numbers across tasks to avoid wasting balances in subsequent detections.

Checklist Step 2: Log in to the console and select the Line filter type

Enter KK-DATA Console and click “New Screen Number Task”. Upload the prepared number file (CSV/TXT supported) and select Line Screen Number in the platform list. You will see multiple detection indicators to check.

Select detection type: Open vs Active vs Gender

Detection type	Function	Applicable scenarios
Line activation detection	Verify whether the number is registered Line	Basic filtering to reduce invalid numbers
Line Activity Detection	Determine whether the number has been logged in/used recently	Target recently active users to increase the reach rate
Line Gender Detection	Identify user gender (male/female, some include age)	Gender-oriented operations, such as only recommending to male users

Recommended combination: activate the test first, and then activate the test twice from the already activated number; if gender is required, you can check it separately (the cost will be accumulated according to the item).

Set gender targeting (if male users are required)

If the activity is only for men (such as men’s skin care products, game promotion), after checking Line Gender Detection, you can filter users whose gender is “male” when exporting. The KK-DATA gender field is determined by an algorithm and usually contains the male/female tag. Some accounts may also include age segments (such as “around 30 years old”). Note: This is not ID-level accuracy, but it is sufficient for most marketing targeting needs.

Export fields: uid, activation status, gender, etc.

Before submitting the task, you can customize the exported fields. It is recommended to check at least:

• number (original number)
• Line activation status (Y/N)
• uid (the unique identifier of Line, which can be used for subsequent secondary contact or matching)
• Gender (if gender detection is checked)
• Country code (optional)

These fields will be available for download as CSV/TXT upon completion of the task.

Checklist Step 3: Confirm fees and balance before submission

Before clicking “Submit Task”, the console will clearly list: -Total number of numbers to be tested

• The selected detection type and corresponding unit price
• Estimated total cost

KK-DATA adopts the no subscription package, per-item payment model. The fee will be deducted from the balance only after the task is completed. If the balance is insufficient, new tasks cannot be submitted. It is recommended to recharge an appropriate amount of USDT in advance to avoid interruptions.

Checklist Step 4: View task progress and result notifications

After submission, the task will enter the queue. You can:

• Console real-time view: The page automatically refreshes the task status (queuing → processing → completed).
• Telegram Notification: Bind Telegram on the console in advance, and you will receive automatic reminders when the task is completed.

Understand task queue and processing time

Processing time depends on the number of numbers and current platform load. Usually:

• 5000 activation detection: about 1–3 minutes.
• 100,000 combined detections (enabled + active): approximately 10–30 minutes. There is no need to stay on the page while waiting, just come back and download when the notification arrives.

Download filter results and import into CRM

After the task is completed, click “Download” in the console and select CSV or TXT format. The result file contains the fields you checked. For example:

号码,Line开通状态,uid,性别
+818012345678,Y,123456abc,男
+818012345679,N,,待定

Import the number with “Line activation status = Y” into the CRM or sending system to carry out follow-up activities.

Best practices after activating data detection for Line

Obtaining Line activation data is only the first step. To maximize ROI, it is recommended to:

1. Second Activity Detection: Submit a Light activity detection for already activated numbers to exclude long-term inactive accounts for further filtering.
2. Gender stratified operation: Use the gender field to send different content to male/female users to increase click-through rates.
3. Data deduplication: Avoid waste caused by repeated detection of the same number between multiple activities. Use KK-DATA data deduplication warehouse to automatically merge and deduplicate, and the same number will only be detected once.

4. Result import automation: Import the exported CSV into your marketing tools (such as WhatsApp broadcast system, CRM, etc.) through API or manually to achieve a closed loop from screening to reach.

What is Line activation data? Differences from other platform screening numbers

Line activation data refers to the result of confirming that the mobile phone number has registered a Line account after passing the number screening platform detection. It is not the same as “active” or “live-reachable” - the user may have logged out, changed devices, or been offline for an extended period of time. Therefore, it is recommended to use it in conjunction with activity detection.

Compared with the screening process of other platforms (such as Telegram, WhatsApp), the steps of Line screening are essentially the same:

• Upstream: Number preparation (generation/import) → Midstream: Platform detection (activation/active/gender) → Downstream: Result export.
• Difference: Line’s user profile is biased toward Japan, Taiwan, and Southeast Asia; Telegram is biased toward the encryption circle, Russia/Eastern Europe; WhatsApp has wider global coverage. But the operation is to upload the number → select the detection item → get the result, the logic is consistent.
