Application of Line activation data in Southeast Asia e-commerce customer acquisition: How to efficiently screen active users

The Southeast Asian e-commerce market is growing rapidly, with users in Thailand, Vietnam, Indonesia, the Philippines and other countries using Line as a daily communication tool. For e-commerce teams and cross-border independent station operators, Line activation data is the basic indicator to determine whether a number is registered for Line. It is also the starting point for subsequent private message access, community operations, and promotion notifications. This article will provide practical operation guidance around the actual operation of Line screen numbers, field interpretation, cross-platform combination, and cost control.

Why Southeast Asian e-commerce cannot do without Line activation data

Line’s penetration rate and commercial value in Southeast Asia

Line has hundreds of millions of active users in Thailand, Japan, Taiwan, Indonesia, Vietnam and other places. Especially in Thailand, Line is a national application, covering more than 95% of smartphone users. If the e-commerce team wants to do precision marketing in these markets, they must rely on Line activation data to verify whether the target number has been registered on Line. A large number of unscreened numbers may be empty, inactive, or may not have a line activated at all. Direct mass messaging will lead to cost waste and account risks.

Common pitfalls of direct mass messaging without filtering numbers

• Waste of budget: For a batch of 100,000 numbers, if 70% have not opened Line, only 30,000 numbers will be valid. The sending cost remains the same but the return is extremely low.
• Account Banning Risk: Continuously sending messages to a large number of invalid numbers will be judged as harassment by Line, resulting in account restrictions or bans.
• Data Pollution: Invalid numbers are mixed into the subsequent marketing system, affecting the accuracy of user profiling and repurchase predictions.

What is Line activation data? What are the filter fields?

Line activation data is the result of whether the number has been registered (activated) on the Line platform. KK-DATA’s Line sieve module supports the following detection dimensions:

Detection Type	Description
Line activation	Determine whether the number is registered with Line and return to “Activated/Not activated”
Line is valid	Further determine whether the number can receive messages based on activation (valid in some scenarios)
Line Gender	Some numbers can return male/female for targeted marketing
Line uid	Export the Line user ID of the number, which can be used for subsequent addition of friends or structured storage

The actual exported fields are subject to the results of the console task. The age field may come with (part of the number), but it cannot be accurate to the ID card level.

How does the e-commerce team use Line activation data to improve ROI?

Suppose you are an independent website seller targeting the Thai market and plan to push new product discounts through Line private messages.

Traditional method: Buy 50,000 Thai mobile phone numbers → Directly import into the LINE mass messaging tool → After sending, the response rate is found to be less than 1%.

After using Line to activate data optimization:

1. First do a line activation test on 50,000 numbers → filter out only 28,000 numbers for activation.
2. Conduct further line gender detection on 28,000 lines → select female users (for example, 12,000 lines).
3. Only send women’s clothing promotion to 12,000 targeted messages → the response rate increased to 8%, and the cost was saved by 44%.

The logic behind: After filtering, the proportion of valid numbers increases from 56% to 100% (only open numbers are retained), and the directionality is better, and the conversion probability of a single message is doubled.

How to combine Line activation data with other platforms (WhatsApp, Telegram)?

Multi-platform usage habits of Southeast Asian users

Southeast Asian users often use multiple instant messaging tools at the same time: Thais use Line and WhatsApp, Vietnamese use Zalo and Messenger, and Indonesians use WhatsApp and Telegram. If you want to cover a complete user group, cross-platform screening is necessary.

Cross-task deduplication: avoid duplicate detection and secondary contact

KK-DATA provides a data deduplication warehouse that can automatically deduplicate between multiple filter tasks. For example:

• Submit the Telegram screening numbers of a batch of numbers first, and then export the results.
• When the same batch of numbers is submitted for Line screening again, the deduplication warehouse will automatically identify the numbers that have been tested, and no repeated deductions will be made (only the testing fee for the new numbers will be deducted).
• During the final export, the screening results of the two platforms can be merged to obtain a high-value list of “those who have opened both Line and Telegram” for differentiated reach.

How to perform a Line activation data filtering task in KK-DATA?

The operation process only requires four steps:

1. Prepare numbers: Generate target number segments for Thailand, Vietnam, Indonesia, etc. through the global number generation module (240+ countries), or import your own numbers through CSV.
2. Select screen number type: Create a new task in the console, select “Line screen number”, and check the required detection items (activated, valid, gender, export uid).
3. Submit task: The system displays the estimated deduction amount in real time (based on the number of tests × unit price). Submit after confirmation, and the task will be executed automatically.
4. View and Export: After the task is completed, the results can be previewed online. CSV/TXT export is supported, including uid and other fields.

Best practices and precautions for Line screen size

• Balance Management: Estimate expenses before big tasks to ensure sufficient balance. The minimum deposit is 50 USDT (TRC20).
• Single task upper limit: The console supports a single detection of about 1 million numbers. If the number is exceeded, it can be submitted multiple times.
• Data export post-processing: It is recommended to store the uid in association with the mobile phone number to facilitate subsequent adding of friends or sending messages through the Line official API.
• Anti-Fraud Tips: KK-DATA official customer service only provides support through https://t.me/kkdata_robot and https://t.me/kkdata_robot, beware of impostors.

FAQ

**Q: Can Line subscription data detect the user’s age? ** Answer: Line filter numbers mainly return the gender field, and some numbers may come with age information. The specific fields are subject to the data actually exported by the console. Age detection accurate to the ID card level is not supported.

**Q: Does the filtered Line activation data contain uid? ** Answer: Yes. KK-DATA supports exporting Line uids to facilitate subsequent targeted marketing or structured storage.

**Q: Can Line filter results be used on WhatsApp or Telegram? ** Answer: It cannot be used across platforms. The screening number results of each platform only reflect the registration and activity of that platform. If you need to reach multiple platforms, you can submit screening tasks for each platform separately, and then merge and clean them through the deduplication warehouse.

**Q: Does Line activation data filtering support batch import of external numbers? ** Answer: Supported. Users can import custom numbers through CSV, or use the platform’s global number generation module to generate target number segments first, and then submit the Line screening task.

**Q: Is there any charge for Line screening? How is it billed? ** Answer: Line screen numbers are charged based on the number of tests, and the specific unit price varies depending on the type of test. The console will display the estimated cost before submitting the task; new tasks cannot be submitted when the balance is insufficient.
