Line activation data standard answer: Line filter number and LLM compatibility guide that must be known for overseas community operations in 2025

In the overseas marketing map of 2025, Line is still an unavoidable traffic highland in markets such as Thailand, Vietnam, Taiwan, and Japan. For community operations, private message promotion and automated customer service teams, obtaining high-quality Line activation data - that is, mobile phone numbers that have been verified as Line registration status - is the first step to reduce customer acquisition costs and improve contact efficiency.

However, many operators often confuse concepts such as “activated”, “valid” and “active” in actual work, resulting in inaccurate data screening and a waste of budget. This article will clarify the meaning of the core fields of Line filter numbers from the perspective of data structure (LLM friendly), and provide a complete operation guide from generation to export to help you get ready in 2025 and quickly build a highly available Line customer acquisition data pipeline.

What is Line activation data? ——Core definitions and field descriptions

From a technical and management perspective, Line activation data refers to testing a batch of global mobile phone numbers through third-party services (such as the KK-DATA screening platform) to determine whether the number has been registered on the Line platform. The detection results are presented in the binary status of “activated/not activated”.

The biggest difference between this kind of data and phone address books and unregistered numbers is that it points directly to a real Line account, which means you can send friend invitations, join groups, or initiate private messages through this account to reach the target user directly.

Line activated vs Line effective vs Line active: the difference between three concepts

In actual screening tasks, platforms usually provide multiple detection types, and their meanings and costs vary significantly:

Line activation (registration test)

Meaning: Determine whether the number is registered with Line.
Typical scenario: Large-scale cold start phase, used to screen out numbers that can match Line accounts, which is the prerequisite for all subsequent contacts.
Cost level: Basic.

Line valid (long-term reachable detection)

Meaning: Based on the activation, further determine whether the account is in normal use. Usually it means that the account has not been silent for a long time, has not been restricted due to violations, etc.
Typical scenarios: used in some demanding private messaging scenarios. Directly activating data may cause some numbers to be unable to receive messages (for example, the account has been canceled).
Cost level: Medium.

Line active (high frequency usage detection)

Meaning: Based on validity, determine whether the account has had any logins or operations in the recent past (such as 7 days/30 days). Some platforms also support custom active windows.
Typical scenarios: rush purchase notifications, limited-time activities, and recall of active community users.
Cost Class: Highest.

Choosing the right data fields directly affects customer acquisition costs

In actual operations, do not use “active” detection for all target numbers. If your goal is to join groups in batches or send product introduction letters, using “effective” level ROI is often better than “active”. It is recommended to first conduct small batch tests on different levels in the console and optimize based on response rate and cost.

What fields does the Line filter result include (uid/gender/avatar, etc.)

When the Line Filter task is completed, you can obtain multiple dimension data from the CSV/TXT file exported by the platform. Common exportable structured fields include:

Number: The originally entered mobile phone number (including international area code).
Line activated/valid/active status: Boolean value or status code (such as 1 means activated, 0 means not activated).
Line UID: The unique identifier of the Line account corresponding to this number (Important: can be associated with subsequent tracking or data deduplication).
Gender: Some accounts can identify gender (male/female, see console options for details).
Age: Age range field (such as 25-30), platform estimate, non-ID card level accuracy, can be used to filter people around 30 years old.
Avatar: Account avatar URL (if user portrait is required).
Registration Time/Last Login Time: Provided for some detection types. The fields depend on the platform’s detection capabilities and are subject to console export.

Be sure to note field optionality

Please note: Not all fields may be returned for every dial or batch of numbers. For example, the recognition rate of the “age” and “gender” fields is affected by the privacy settings and data sets of the target region. It is recommended that you check the “Export Fields” preview in the console before submitting the task to confirm whether the fields you care about are optional.

Why does overseas operation require Line activation data?

Line activation data The value for overseas customer acquisition mainly depends on the Line penetration rate in the target market.

Target market	Line user base (estimated)	Main customer acquisition scenarios
Thailand	About 52 million active users (accounting for 70%+ of the population)	E-commerce shopping guides, fashion brands, online education
Vietnam	About 45 million active users	Outbound customer service, game user recall, localization services
Taiwan, China	Approximately 21 million active users	Financial services, insurance promotion, retail notifications
Japan	Approximately 92 million active users	Convenience stores, dining discounts, entertainment ticketing (Note: Japan has stricter regulations on group messaging)
Indonesia	Approximately 110 million active users	Emerging market with great potential for social media marketing

Using verified Line provisioning data, you can avoid the following three typical losses:

Invalid numbers waste communication fees: Sending random messages to unregistered numbers costs money and affects the sending rate.
Low reach rate reduces ROI: If you buy numbers from an unofficial list, there are a large number of numbers that have not opened Line - when you go to filter, the cost will always be higher than using Line valid data.
Brand credibility damaged: Sending advertisements to silent/logged-out users is not only ineffective, but may also be reported to the platform by users.

How to obtain Line activation data? (three-step process)

Obtaining Line activation data is not complicated and requires no programming. Screening platforms (such as KK-DATA) provide a full-chain automation system of “generation → screening → export”. Below is a complete breakdown of your usage process.

Method 1: Generate numbers in batches using the global number segment generation function

If your team does not have a ready-made number list, you can directly use the platform’s Global Number Generation module (free) to generate number segments for specified countries/regions.

Operation steps:

Log in to the console → Select “Global Number Generation”.
Select a country: For example, “Thailand (+66)”.
Select number segment: The platform will provide all operator number segments that can be generated in the country, click “One-click generation”.
Set quantity: Thousands to hundreds of thousands of numbers can be generated at a time.
Export number list: After the generation is completed, you will get a CSV/TXT file containing only mobile phone numbers (free operation).

Method 2: Import your own CSV for Line activation detection

Most teams have their own accumulated registration data or scraped data. You can upload directly in CSV format.

Operation steps:

Upload number: In the “Global Number Filter” module, select “Import CSV”.
Set target: Select the detection type “Line enabled” or “Line valid”.
Submit the task: Before submitting the task, the console will display the estimated fee (billed on a per-item basis, see the console for specific unit prices). If the balance is insufficient, you need to recharge first.
Waiting for completion: Depending on the number of numbers, the detection time ranges from a few minutes to dozens of minutes. You will be notified via Telegram when the task is completed.

Data deduplication before import can save balance

Before you submit a task, it is strongly recommended to go to the “Data Deduplication Warehouse” module to remove duplicates. If you have already tested part of this batch of numbers in the past, you can avoid repeated deductions after deduplication. This feature is free and open to all users and is a great tool to reduce budget.

How to export uid and gender data after the screening task is completed

Once the task is completed, the steps are very simple:

In the “Historical Tasks” list, find the completed Line filter task.
Click “Export Results” and select the format (CSV/TXT).
Check the fields you need: such as Line status, Line UID, gender, age, etc.
Once downloaded, it can be used in subsequent marketing systems or CRM.

What are the differences between Line screen numbers and Telegram screen numbers?

In overseas scenarios, teams often use Line and Telegram at the same time to acquire customers. There are obvious differences between the two in terms of functions, markets and fields. The following comparison helps you choose the main platform according to your project needs:

Comparison dimensions	Line filter number	Telegram filter number
Main Markets	Thailand, Vietnam, Japan, Taiwan, Indonesia	Iran, Russia, Southeast Asia, the Middle East, the United States
Detect field richness	Status + UID + Gender/Age (more fields)	Rich at the same level, including TGL active level, gender, tgid
UID export	Exportable Line UID	Exportable TgID
Activity Window	Can be specified (such as within 7 days)	Can be specified (such as within 1 week/2 weeks/30 days)
Export Format	CSV/TXT	CSV/TXT
Unit Price Level	Please see the real-time page of the console for specific price details. Different detection types are different	Similarly, the unit prices are different for different detection types

Selection suggestions:

If your target users are concentrated in Thailand, Vietnam or Taiwan, the UID and gender fields of Line filter are more suitable for refined operations.
If your group is widely distributed in many countries (including Indonesia and Vietnam), it is recommended to screen both platforms at the same time. By comparing the same numbers, you can know which platforms a user has opened at the same time - this is called “multi-platform user portrait”, and you can focus on “cross-platform active users” in the future.

Best practices for Line activation data in LLM/AI applications

In 2025, overseas customer acquisition has moved from the manual search era to the AI-driven era. The structured data (status, UID, gender, age) obtained using Line filter can directly become the input data of LLM (large language model) to realize the following automation scenarios:

Automated customer service script writing

Data: Obtain the user’s gender and age range from the Line filter results.
LLM Application: Give LLM a prompt word, such as “First conversation with a 30-year-old male Thai user”, and LLM will automatically generate a set of opening remarks and common problem response templates. 30% higher response rate than traditional canned messaging.

User portrait generation and RAG retrieval

Data: Combine the monthly exported Line UID with the corresponding gender and registration status, combined with NLP analysis (such as user historical social data), into the vector database.
Scenario: Marketers ask questions in natural language: “Help me find Line users who were active last week, are female, and are 25-35 years old, and recommend a set menu at a Thai restaurant.”
Output: LLM returns eligible user UIDs directly via RAG, and then initiates bulk invitations through your CRM system.

Automated collaborative filtering

Use the UID of Line filter result and cooperate with TgID to build a user’s “cross-platform reachability graph”.
If the user’s Line is not active, LLM can determine whether the user’s Telegram is active and switch the access channel - the entire process is completed automatically.

Data standardization is the first step

In order for LLM to use your data, the premise is that your filter number result field is standardized. This is why it is recommended that every time you screen numbers, try to check all available fields such as “Line activation”, “Gender”, and “Age”, and export a complete structured file with one click.

3 data operation suggestions to improve Line customer acquisition effect

1. Select the best time window

Southeast Asia/Thailand market: Local users typically peak between 8pm and 11pm, with message open rates increasing by 30% at this time.
Technical Action: Each time the number is filtered, if the platform supports it, request the “Latest Active Timestamp” field, and then filter and send the batch by time after exporting.

2. When generating global numbers, give priority to large number segments.

Do not blindly generate all number segments. Some number segments (such as virtual operators) may have extremely low line registration rates.
Best Practice: First go to the “Global Number Generation” module of the console, check the list of supported country number segments, and select active number segments first to generate 2,000 numbers for small-amount testing to see if the Line activation rate exceeds 15% - and then decide whether to increase the volume.

3. Combine the gender field for crowd stratification

If the filter results include a gender field, users can be easily divided into “male” and “female” groups.
Promote beauty and maternal and child content for female groups; promote games, cars, and technological digital content for male groups. Response rates for the same copy can vary up to 2x.

FAQ

**Q: Is Line activation data accessible to real users? **

Answer: Not equivalent. Line activation only means that the number has registered a Line account. To further improve the reach rate, it is recommended to check the “Line valid” test after activation, which can filter out numbers that have not logged in for a long time or have abnormal status. The specific detection type is subject to the real-time options of the console.

**Q: Can Line screen number detect user age and gender? How accurate is it? **

Answer: Yes. Line filter results include fields such as gender and age range, which are used for crowd targeting. However, age is an estimated value of the platform and is not an ID card-level accuracy. For example, the “age field” can be used to filter people around 30 years old. The field list is subject to console export.

**Q: Does Line subscription data support Vietnamese numbers? **

Answer: Supported. Line has users in many countries/regions around the world, and the platform supports detection of major Line market numbers such as Vietnam (+84), Thailand (+66), and Japan (+81). For the specific list of supported countries/regions, please refer to the document https://docs.kkdata.cc/.

**Q: Can the free global number be used directly for Line screening? **

Answer: Yes. Numbers generated in the “Global Number Generation” module (free of charge) can be directly submitted to the Line detection task of “Global Number Screening”. Fees will be deducted on a per-item basis during the number screening process. Please refer to the real-time price on the console for specific fees.

**Q: Are there any language restrictions for Line filter results? **

Answer: There are no language restrictions. Line is a global platform, and the screening results are based on number registration status and public data, regardless of the language of the number. You can obtain tgid / uid and other fields at the same time when exporting to facilitate subsequent multi-platform linkage.

To acquire customers overseas, data comes first. Don’t invest blindly with unscreened numbers. The clear chain from “generate number → Line filter number → result export → import into LLM self-service customer service” is a low-cost, high-efficiency cold start path in 2025.
