Complete guide to exporting Line valid numbers: How to obtain Line activation/activity/gender data in batches

When promoting in the Southeast Asian market, Line is an unavoidable customer acquisition channel - hundreds of millions of users in Thailand, Vietnam, Indonesia and other places rely on it for daily communication and business interactions. However, blindly sending mass messages to numbers that are not registered with Line not only wastes budget, but may also trigger operational risks. line valid number detection becomes the first step for the overseas marketing team. From the detection principle, field interpretation to practical export, this article completely breaks down how to obtain Line activation, activity, and gender data in batches, helping you directly transform the screening results into actionable customer acquisition actions.

What is Line valid number detection?

The essence of Line valid number detection is to determine whether the target number has registered a Line account through the communication protocol. It solves the core problem of “Is there an active Line user behind this number?” Many teams put out advertisements or private messages with a phone list. As a result, a large number of numbers are empty or unregistered, and the click-through rate and conversion rate are naturally bleak.

What is the difference between Line “open” and “active”?

• Activation detection: Only determine whether the number is registered as a Line account. The result is usually “yes/no” and is suitable for the first round of filtering.
• Activity Detection: Based on activation, further determine the recent online or usage status of the account. For example, whether there has been active behavior within 7 days. Activity data can be used to set the push rhythm to avoid harassing users who have not logged in for a long time.
• Gender Detection: Analyze the user’s gender based on the account’s public information (such as name, avatar, personal profile). Some platforms also provide age fields (for example, they can filter people around 30 years old), but ID-level accuracy cannot be guaranteed.

In what scenarios is valid Line number data required?

• Line Group Invitation/Private Message Promotion: Screen out the activated numbers first, eliminate invalid numbers, and reduce the probability of being blocked.
• Line OA Operation: Targeted delivery of coupons or event information based on activity levels.
• Cross-border e-commerce customer reach in Southeast Asia: In key markets such as Thai beauty, Vietnamese electronic products, and Indonesian home furnishings, Line is the main social channel for acquaintances.

What data fields does Line valid number export support?

In the Line filter task of the filter platform (such as KK-DATA), the export file usually contains the following common fields (subject to the actual display on the console):

Field name	Description	Practical scenarios
phone	Original number (international format)	Used for subsequent import tools or platforms
line_registered	Whether to activate Line (true/false)	First round of screening: keep the activated number
line_active	Whether active (true/false)	Accurately hit recent online users
gender	Gender analysis (male/female/unknown)	Gender-targeted promotions
age_group	Age range (such as 25-34)	Age-targeted delivery
uid	Line internal user ID (only provided for some tasks)	Used for higher-level API docking

These fields can be combined and filtered. For example: Only export numbers that are activated + active + female (female) + age 25-34, targeting Thai female users aged 25-34 to promote beauty products.

How to use the screen number platform to complete the batch export of valid Line numbers?

The following takes KK-DATA as an example to explain the complete process from number preparation to export in three steps. The operating logic of other platforms is similar.

Step 1: Prepare a list of Line numbers to be detected

You have two ways to get your number:

1. Prepare CSV/TXT files yourself: Import from historical orders, registration lists, industry databases and other sources, with one number per line (including international area code).
2. Use the platform’s built-in number generation tool: Enter the “Global Number Generation” module, select the target country (such as Thailand +66), specify the number segment or digits, and the system can randomly generate tens of thousands of numbers. No charge for generation, the generated numbers are directly used for number screening tasks.

Step 2: Submit the Line screening task and view the estimated cost

Create a new task in the console:

• 选择平台：Line
• Detection type: You can check enabled, active, gender, age, etc. Different detection types have different unit prices, please see the real-time price on the console for details.
• Upload numbers or import from generation module.
• The system will display the estimated total cost. If the balance is insufficient, you need to recharge via USDT (TRC20) first (minimum about 50 USDT).

After submission, the task will run automatically, and you can be notified through Telegram when completed (you need to bind the notification robot in advance).

Step 3: Export the valid number after the task is completed

After the task status changes to “Complete”, enter the task details page:

• Choose export format: CSV or TXT
• Filter conditions can be set: for example, only export numbers that are enabled and active, or only export data with female gender.
• Click Export to download the file. The file contains all the fields you selected in the task.

The entire process is connected in series into a “Generate → Filter → Export” pipeline, which is suitable for operation teams that handle tens of thousands to millions of numbers every day.

After exporting the valid Line number, how to apply it to actual business?

Obtaining the data is only the first step, how to use it is the core. The following are three common landing scenarios:

Import Line OA user groups by gender

If you are making beauty and skin care products, give priority to female users; games and sports products tend to be more male-oriented. When exporting, use the gender field to divide it into two files, import independent Line OA or private message lists respectively, and send differentiated content.

Set promotion rhythm according to activity level

• Highly active (online in the past 7 days): can send instant promotions and limited-time activities.
• Medium-low activity (online within 30 days): Send gentle reminders or content updates.
• Inactive (not online for a long time): Do not send it temporarily to avoid being reported.

Cross-platform data integration

If you are screening channels such as WhatsApp and Telegram at the same time, you can deduplicate the active users of multiple platforms and merge them into a “network-wide active user pool”, and then focus on Line to follow up (because Line’s privacy restrictions in Southeast Asia are relatively weak). KK-DATA provides a cross-task data deduplication warehouse to avoid wasting balances through repeated detection.

What are the precautions when using the Line number export function?

• Verify official customer service: Beware of fake customer service impersonating the platform. Only through official channels (such as https://t.me/kkdata_robot or https://t.me/kkdata_robot）联系，不要轻信陌生人的推广信息。
• Avoid repeated detection: If the same number is detected repeatedly by different tasks, charges will be deducted repeatedly. It is recommended to use a data deduplication warehouse to ensure that it is only detected once.
• Comply with Line platform policies: Line prohibits large-scale harassing group messaging. Keep the number of private messages per day within a reasonable range (for example, 1-2 messages per user per week), and ensure that the content is not spam.
• Regularly updated data: The activation/active status of the number will change. It is recommended to re-screen the old customer list every 3-6 months to eliminate canceled or inactive numbers.

FAQ

Question: Are the results of Line valid number detection accurate?

Answer: Line activation/activity detection is based on the open communication protocol to determine whether the number has registered a Line account and its recent online status. The accuracy rate is high, but it is recommended to use small batch testing. Gender and age data are derived from the analysis of public account information and are for reference only and cannot be 100% accurate.

Question: Can the exported Line valid number be used for commercial promotion?

Answer: Yes. Line itself allows businesses to reach users through Line OA or bulk messaging, subject to local anti-spam regulations (such as Thailand’s PDPA). It is recommended not to harass users frequently to avoid being reported and banned.

Q: Does the export file contain gender data? How to judge?

Answer: If you select Line gender detection for your task, the “gender” field will be included in the export results. This data is based on the analysis of public account information and cannot be guaranteed to be 100% accurate, but it has reference value for targeting female/male user groups. The same logic applies to age fields (such as around 30 years old).

Question: How many Line numbers can be detected at most in one task?

Answer: It is recommended that a single task be controlled within 1 million. If the number is larger, it can be submitted in batches. The platform supports a maximum of about 1 million items for a single task, but it is recommended to split them according to detection type and time-consuming to improve efficiency.

Question: I don’t have a list of numbers. Where can I get the Line numbers to be tested?

Answer: You can use the “Global Number Generation” module on the platform to generate batch numbers by country and number segment, and then directly submit these numbers for Line activation testing. There is no charge for the generation, and the screen numbers will be charged on a per-item basis. For example, by generating a Thai +66 mobile phone number segment, you can obtain a large number of potential Line user numbers.
