Line activation data batch detection tutorial: Use KK-DATA to quickly screen out valid Line accounts

In Southeast Asia, Japan, South Korea and Taiwan, Line is the social giant after WhatsApp and Telegram. Whether it is cross-border e-commerce, financial promotion, or localized community operations, Line activation data (that is, whether the number is registered with Line) is the cornerstone of all subsequent precision marketing. Only by confirming that your number is “activated” can you reach out via private message, join a group, or conduct targeted gender promotion. However, in the face of thousands of numbers, it is unrealistic to manually verify each one - this article provides a set of practical batch detection tutorials, combined with the KK-DATA platform, to help you quickly screen out valid Line accounts, and export the results to CSV/TXT for the next step of action.

What is Line activation data? Why is it needed to acquire overseas customers?

Line activation data refers to checking whether the target mobile phone number has registered a Line account. It is the most basic screening dimension: if a number is not registered with Line, then any Line promotion for that number will be invalid; and “activated” means that the number has at least one Line account, which can further determine its validity (whether it can receive messages) and gender.

In Southeast Asian countries such as Thailand, Vietnam, Indonesia, and Malaysia, Line is a national-level application, covering more than 100 million users; in Japan and Taiwan, Line is an important tool for daily communication and business contacts. For overseas teams:

• Community Operation: Use activation data to quickly expand Line groups to avoid wasting energy by adding “empty accounts”.
• Private message promotion: Only send marketing information to accounts that have been opened and valid to reduce the risk of account suspension.
• Precise Targeting: Combined with gender detection, push different content to male or female users respectively to improve conversions.

KK-DATA’s Line filter number supports “activated/valid” detection, and the “gender” field can also be selected, so that multi-dimensional data can be obtained in one task. More importantly, it adopts pay-per-item and no-subscription packages, which is suitable for flexible needs from small to large.

How to prepare the list of numbers to be tested?

The first step in batch testing is the number source. You can obtain the test number through the following channels:

• Owned Number Segment: If you purchase a computer room number segment or SIM card pool in a specific country, you can export it directly.
• User registered mobile phone number: Extracted from existing CRM or activity data.
• Public Data: Obtained through site group crawlers or third-party platforms (pay attention to compliance).

But the fastest way is to use the number generation function of KK-DATA - it supports random number generation and number segment generation in 240+ countries, and it is completely free. This means you can get a huge list of numbers in your target country without spending a penny.

Use the number generator to quickly obtain the target country number segment

1. Log in to KK-DATA Console and enter the “Number Generation” module.
2. Select the target country, such as Thailand (+66), Vietnam (+84), Indonesia (+62).
3. Select the generation mode: randomly generated (completely random) or generated by number segment (specify the first few digits, such as +66 81xxxxxx).
4. Set the number of generated items (it is recommended to try 1,000 items first) and click Generate.
5. Export to CSV file where numbers are automatically converted to international format.

Suggestions on cleaning and deduplication before uploading your own number

If you already have your own number, please perform the following cleanup before importing KK-DATA:

• Removal: Different batches may contain duplicate numbers, and repeated testing will waste balance. Utilize the platform’s [Data Deduplication Warehouse] (https://docs.kkdata.cc/) to automatically remove duplicates across tasks.
• Uniform format: The number must be in an international format, such as +66812345678, and cannot contain spaces, brackets, or characters other than the national prefix.
• File format: Supports CSV (one column recommended), TXT (one number per line). Test run dozens of verification formats before uploading.

Create Line activation data detection task in KK-DATA (step by step explanation)

After preparing the number list, enter the number screening module. Here are the complete steps.

Step 1: Select detection platform and detection type

1. Click “Filter Number” → “Create Task” in the left navigation of the console.

2. Select Line for the platform.

3. Detection types include:

   • Activated/valid: Check whether the number is registered with Line (activated) and whether the account can receive messages (valid). This is the most commonly used option.
   • Activation + Gender: On the basis of activation/validity, gender (male/female/unknown) is additionally detected. It is recommended to check this box if you need to target a male audience (for example, to promote a game or financial instrument).
   • Note: Gender detection is based on account public information and model inference. It is not 100% accurate, but it is enough for preliminary orientation.

4. You can also choose whether to export UID (Line user unique identifier). UID can be used for subsequent API docking (such as group messaging), but please pay attention to comply with Line platform policies.

Step 2: Upload number and confirm fee

1. Upload your number file (CSV or TXT), and the system will automatically complete format verification and deduplication.
2. The platform will display the estimated fee: based on the current Line platform unit price × the number of numbers after deduplication. Please refer to the real-time price of the console for the specific unit price, no need to memorize it.
3. Check whether the balance is sufficient. If it is insufficient, you can recharge through USDT (TRC20), the minimum is about 50 USDT. It will be credited automatically after recharging.
4. After confirming that everything is correct, click “Submit Task”.

Step 3: Wait for the task to complete and receive notifications

After the task is submitted, it enters the queue and is automatically processed in the background. Depending on the number of numbers, the time consumption varies greatly:

• Thousands of numbers typically completed within minutes.
• For tens of thousands of numbers it may take 30 minutes to 1 hour.
• Million-level tasks (the platform supports up to about 1 million items at a time) may take hours.

You can check the progress in real time on the task list. It is recommended to turn on Telegram notification (bind account) when creating a task. After the task is completed, you will receive a message including a result link.

How to interpret the detection results of Line activation data?

After the task is completed, click “Export” to obtain a CSV or TXT results file. The main fields include:

Fields	Meaning	Marketing Recommendations
phone	Original number (international format)	Used for subsequent associated users
line_open	Whether to activate Line (Yes/No)	If not activated, ignore it directly
line_active	Whether it is valid (Yes/No)	Valid means that messages can be received; activated but invalid may be a zombie account or privacy settings
gender	Gender (Male/Female/Unknown)	Only exists when gender detection is checked
uid	Line user unique identifier	Can be used for API calls (subject to Line policy)

Key differences:

• Activated but invalid: The number is indeed registered with Line, but may be unreachable due to privacy settings or long-term inactivity. This type of account has a high failure rate in sending private messages and is not suitable for batch push.
• Open and valid: It is a high-quality target. You can combine gender screening to launch beauty e-commerce for female users, and promote games or financial apps for male users.

About age: The public information of some Line accounts contains the age field, but KK-DATA does not yet provide independent age detection. If necessary, cross-validation can be combined with other platforms (such as Telegram), but do not rely too much on it.

How to use Line gender data for precise targeting? (With case ideas)

If gender is checked in the detection task, the export result will contain the gender field. Common orientation scenarios:

• Male Targeted: Games (SLG, RPG), financial investment, tool apps (VPN, system cleaning).
• Female-targeted: e-commerce (clothing, beauty), mother and baby, social applications.

For example: Suppose you promote an overseas mobile game “Empire Conquest”, and the target audience is men in their 30s. You can:

1. Use the number generator to generate the Thai number segment (+66 8xxxxx).
2. Create a Line screening task and select the “activation + gender” detection type.
3. After exporting the results, filter the numbers line_active = Yes and gender = Male.
4. Combine with other demographic characteristics (such as age, but you need to assume that it is generally 20-40 years old) to form the final delivery list.

Note: Gender detection is only model inference, and there are certain errors. It is recommended to conduct secondary verification for high-value users (such as confirmation through private chat with customer service) to avoid wasting resources due to misdirection.

Common misunderstandings and best practices for batch detection of Line activation data

Misunderstanding 1: Not using international formats

Many novices directly upload “0812345678” or “081-234-5678”, causing detection failure. Country code must be added, such as +66812345678.

Misunderstanding 2: Ignoring duplication

Duplicate numbers will be charged repeatedly. Even if a single fee is not high, thousands of duplicates can waste a large balance. It is recommended that each batch of new numbers be cleaned in a deduplication warehouse first.

Misunderstanding 3: Equating “open” with “active”

Line activation data only means that the number is registered with Line, but it does not mean that the user logs in frequently or can be reached immediately. If activity data is needed, the current KK-DATA Line screen number** does not yet provide dedicated activity detection**, but you can indirectly judge through the “valid” field: valid accounts have usually logged in recently. A more accurate liveness assessment can be combined with messaging testing (self-verification required).

Best Practices

• Small-scale trial run: Before the official task, use 50-100 numbers to test the format, cost and result fields, and then submit them in batches after confirmation.
• Submit in batches: If the number exceeds 100,000, it is recommended to divide it into multiple tasks to facilitate monitoring and timely adjustment.
• Balance Management: Check the balance arrival status in time after recharging USDT. Pay attention to the estimated cost before each task to avoid failure due to insufficient balance midway.
• Multi-platform cross-screening: Detect Telegram and WhatsApp at the same time to get a more complete user profile.

FAQ

**Q: How long does it take for Line to activate data detection? ** Answer: Mainly depends on the number of numbers. For thousands of messages, it usually takes a few minutes; for tens of thousands of messages, it takes 30 minutes to an hour; for millions of messages, it may take several hours. You can check the real-time progress in the task list, and you will be notified through Telegram when completed.

**Q: Can numbers whose test results show “not activated” be retested? ** Answer: Yes, but it is recommended to wait more than 48 hours. The reason why it is not activated may be because the number is not registered or the platform is temporarily out of order. There is a certain probability that it will become activated after retesting. However, please note that retesting will consume your balance again. It is recommended to use the deduplication warehouse to filter historical results first.

**Q: How accurate is Line gender detection? ** Answer: Gender is based on account public information and model inference, which is not 100%, but usually has a higher accuracy for mainstream countries (such as Vietnam and Thailand). It is not recommended to make the final decision based on the gender field alone. It can be used in combination with other indicators (such as country, valid status).

**Q: Can KK-DATA detect the activity of Line numbers? ** Answer: Currently, Line screening mainly supports “activated/valid” and “gender” detection, and Line activity detection is not provided separately yet. If you need activity indicators, you can refer to the “valid” field (activated and able to receive messages), or verify it yourself through the message sending test.

**Q: After batch detection of Line activation data, what is the use of the exported UID? ** Answer: UID is the unique identifier of a Line user and can be used to add friends or send messages through the Line API later. However, please note that misuse of UID may violate the Line platform terms and lead to account suspension. It is recommended to use it reasonably and compliantly.
