Complete Guide to Line Activation Data: Detection Principles, Batch Screening Plans, and Practical Practice in Acquiring Customers Overseas (2025)

In Vietnam, Thailand, Indonesia and Taiwan markets, Line is one of the social messaging applications with the highest user penetration rate. For the overseas marketing team, the core value of line activation data is that it tells you which mobile phone numbers have actually registered Line accounts. Without this data, the private messages, group invitations, and brand messages you send will be useless.

This article will provide a complete and implementable guide focusing on the underlying logic of Line activation detection, the batch screening operation process, the application strategy of exported fields, and compliance risks. Whether you are doing private domain operations, independent site promotion, or an agency operation team, you can find directly executable solutions.

What is Line activation data? Why is it important for overseas marketing?

Line activation data, simply put is “whether this mobile phone number is registered with Line”. When you get a batch of mobile phone numbers in the target market, you can quickly filter out those numbers that have activated Line through detection, so that you can conduct subsequent private message contact or social media traffic.

Line’s core application scenarios for data activation

• E-commerce private message promotion: Push promotions and coupon links to users who have opened Line. The reach rate is much higher than text messages or emails.
• Community Operation: Screen out active Line users in the target country and invite them to the brand community (group or official account).
• Brand Communication: Customer service and notifications are sent through Line official account (OA), provided that the other party has opened Line.
• Targeted Surveys/Testing: Use small batches of data to verify local user dependence on Line before entering new markets.

The difference between Line number screening and traditional number cleaning

Comparison dimensions	Traditional number cleaning (number format verification)	Line screening (platform-level detection)
Detection content	Area code, number length, number format	Whether to register Line, active status, gender, uid
Usage scenarios	Basic data collection	Precision marketing, user portraits
Data value	Low (only ensures correct format)	High (executable reach)
Typical tools	Excel formulas, regular scripts	KK-DATA and other screening platforms

From the perspective of marketing ROI, every “opened” number output by the Line filter means a real contact opportunity, not just a “possibly correct” format.

The underlying logic of Line activation detection: How to determine whether a number is registered with Line?

Line’s registration detection is based on protocol-level interaction. The platform will send a similar registration verification request to the Line server without exposing your identity, and determine whether the number belongs to a Line user based on the return status. The entire process does not involve hacking accounts, brute force logins, or stealing user data.

Which scenarios are suitable for activation detection and active detection?

• Opening Test: Quickly determine whether the number is registered, suitable for the preliminary screening stage. If the goal is to add friends or join a group, the enabled status is sufficient.
• Activity Detection: Based on activation, further determine whether the user is online or using Line recently. Suitable for scenarios that require a high response rate (such as limited-time event promotion).

For most customer acquisition scenarios, it is most economical to do the activation test first and then do the activity test on the activated number**. KK-DATA supports the simultaneous selection of multiple detection types in one task without repeated submission.

The actual meaning of gender identification (including age field) in Line filter number

KK-DATA’s Line filter number supports returning gender and age fields (partial numbers). This means that you can not only filter out “users who have opened Line”, but also further distinguish between males and females, or filter out the target group around 30 years old.

For example: You are promoting a men’s skin care product, and the target market is Thailand. Through the gender field of the Line filter, you can directly exclude female users and only reach male users who have opened Line with messages, greatly increasing the conversion rate and reducing harassment complaints.

How to perform Line batch screening efficiently? KK-DATA platform operation process analysis

The whole process is divided into three steps: prepare the number → submit the test → export the results. The KK-DATA console provides visual operations without writing code.

Step one: Get the number to be screened (global number generation or custom CSV import)

You have two ways to get the number to be screened:

1. Global Number Generation (Free): In KK-DATA’s Number Generation Module, select the target country (such as Vietnam, Thailand), and the system will randomly generate a number corresponding to the number range. The generation is free and millions of numbers can be generated on demand.
2. Customized CSV import: If you have a ready-made list of customer numbers (including international area codes), upload the CSV file directly, and the numbers will enter the queue to be detected.

Step 2: Submit the Line screening task (select the detection type and confirm the estimated cost)

On the task creation page of the console:

1. Select the detection platform as Line
2. Check the required detection type: activated, active, gender (multiple choices available)
3. The system will automatically calculate the estimated fee based on the number of numbers and detection type (billing by item, see the real-time price on the console for details)
4. Submit the task after confirming that the balance is sufficient

Billing Instructions: KK-DATA has no subscription package, the recharge method is USDT (TRC20), the minimum is about 50 USDT. After each task is completed, it will be deducted from the balance and you will pay as much as you use. It is suitable for small and medium-sized teams with variable sizes.

Step 3: Export the filtering results (CSV/TXT, including uid, gender and other fields)

Once the task is completed, you can choose the export format (CSV or TXT) on the results page. Exported fields include:

• Number: Original mobile phone number
• Activation status: 1 (activated) / 0 (not activated)
• Activity: the most recent active time period or level
• Gender: male/female/unknown
• Age: Some numbers have age values
• uid: Line user’s unique identifier (can be used for subsequent addition of friends or association analysis)

Detailed explanation of the Line filter number export field: How to use uid, gender, and activity for refined operations?

After obtaining the exported data, the simple “activated” list has limited value. You need to combine fields.

List of common field meanings

Field	Meaning	Operational significance
开通状态	0/1	Determine whether this number can be used for subsequent operations
活跃度	High/Medium/Low/Unknown	Determine whether the user has been online recently, which affects the response speed
性别	male/female/unknown	Push content by gender
年龄	Numeric value or interval	Stratify users by age group
uid	0/1	Unique identifier, can be used to connect with third-party tools

Practical techniques for filtering male/female users (combined with gender field)

Assuming that your product is a beauty product for the Vietnamese market (women first), you can:

1. Use Excel to filter the exported results 性别 = female
2. Then add these numbers to Line friends or send them to private messages
3. If there is an age field at the same time, you can further filter out people aged 18-35

On the contrary, for games, finance, and men’s skin care products, filter 性别 = male.

Use uid for batch friend addition or targeted reaching

uid is the internal ID assigned by Line to the user (usually a string of numbers). Through uid you can:

• Add friends in batches in third-party tools that support uid
• Connected to the CRM system to record the results of each contact
• Avoid adding the same user repeatedly (uid is fixed)

Note: Adding friends directly still needs to abide by the Line platform rules to avoid risk control triggered by a large number of operations in a short period of time.

When overseas teams use Line to activate data to acquire customers, what pitfalls and compliance issues must they pay attention to?

1. Avoid violating Line platform rules

• Do not frequently add strangers as friends: Line has strict restrictions on adding a large number of friends in a short period of time, which may result in account restrictions or bans.
• Don’t send spam: Even if the other party is an activated user, it does not mean that you can send advertisements arbitrarily. It is recommended to first add the other party’s address book or contact them through their official account.

2. The number format must be correct

• All numbers must contain the international dial code and remove the ”+”, “space”, and ”-” symbols. For example, a Vietnamese number should be written as 84912345678 instead of +84 91 234 5678.
• If the number format is wrong, the KK-DATA platform will prompt you when the task is created. You can also view examples of the correct format in Documentation.

3. Obtain data legally and be wary of fraud

• Do not purchase number lists from unknown sources, especially “black data” containing personal privacy. Not only may this data be invalid, it may also expose you to legal liability.
• There is currently a fake KK-DATA customer service scam on the market. The only official channel is the robot account https://t.me/kkdata_robot. Anyone who actively privately chats with you about “need to pay in advance” or “purchase special packages” is a scam.

FAQ

The following has compiled several frequently asked questions about Line activation data to help you quickly resolve your concerns.

**Q: Can Line activation data be guaranteed to be 100% accurate? **

Answer: The platform uses protocol-level detection, which has extremely high accuracy. However, affected by factors such as the network environment and changes in the status of the target number (such as user logout, not connected to the Internet), the results of a very small number of numbers may be biased. It is recommended to use a small batch test first and compare it with the actual reach results for verification.

**Q: Can the Line filter screen out female users? **

Answer: Yes. KK-DATA’s Line detection supports gender fields and can identify male/female/unknown. This information will be included in the export results to facilitate your gender-targeted promotion. At the same time, some numbers also contain an age field, which can be used for more detailed stratification.

**Q: Is there any limit on the number of numbers for batch screening? **

Answer: A single task supports up to about 1 million numbers. If the quantity exceeds this range, it can be submitted in multiple batches. KK-DATA’s data deduplication warehouse will record the results of each test, and duplicate numbers will not be deducted twice, helping to control costs.

**Q: How is the cost of Line screening calculated? **

Answer: Different detection types (activated/active/gender) have different unit prices. KK-DATA adopts a per-item payment model and does not have a subscription package. The console will display the estimated fee before submitting the task, and the actual deduction will be based on the number of tests after the task is completed. For specific prices, please refer to the console’s real-time price or official website billing page.

**Q: How long can the uid in the Line filter result be used? **

Answer: uid is the unique identifier of a Line user and is usually valid for a long time unless the user cancels the account or has not used it for a long time. It is recommended to use it as soon as possible after exporting to avoid operation failure due to user status changes.
