The difference between Line activation data and Line valid numbers: Why do operators need to pay attention to these two?

People who operate Line communities or acquire customers overseas often encounter a confusion: even though the test result is “activated”, when you send a message, it keeps showing “read” instead of “unread” or even gets blocked directly? The problem is probably that you are using Line activation data as Line valid number. There seems to be only two words difference between the two, but the actual screening methods, business value and costs are completely different. This article will thoroughly explain their concepts, compare usage scenarios, and give best practice paths for implementation.

What is Line activation data? What is a valid Line number?

Line activation data refers to detecting whether the number has registered a Line account through the mobile phone number. As long as this number has successfully created a Line account at some point in the past, the test result will show “opened”. What it tells you is the basic fact: This number belongs to a Line user.

Line valid number not only confirms that the number is registered with Line, but also further verifies whether the account is currently in a normal state that can send and receive messages. A valid number usually means that the account has not been deleted, has not been officially banned, and can initiate or receive messages under normal network conditions. Some detection platforms will also combine dimensions such as “recent online” and “activity window” to give more detailed labels, such as “online in the last 7 days” or “behavior in the last 30 days.”

It is important to note that different detection platforms may have different definitions of “valid”. Some platforms consider “no error code returned after sending message” as valid, others rely on longer-term activity indicators. Therefore, after getting the data, be sure to check the exported fields to confirm the specific meaning - the field names exported from the console shall prevail.

Line activation data vs Line valid numbers: comparison of core concepts

In order to understand the differences between the two more intuitively, let’s compare them from four dimensions:

Comparison dimensions	Line activation data	Line valid numbers
Detection dimension	Only verify whether the number is registered with Line	Verify registration + current status of sending and receiving messages
Business purposes	Add friends in batches, basic account confirmation, preliminary screening	Private message marketing, active reach, precise promotion
Applicable scenarios	Community recruitment, user portrait screening, cold start	Marketing activities, notification push, private domain conversion
Data stability	Some numbers may have been deleted/frozen	Currently reachable, but may change over time
Acquisition cost	Relatively low (low detection complexity)	High (requires deep detection)

Detecting differences in dimensions

Line activation detection only requires one API request to determine whether the number belongs to a Line user. The detection of valid Line numbers usually requires multiple steps: first confirm the activation, then simulate sending a message (or read the account status field), and even check whether the account is banned and whether “blocking non-friend messages” and other conditions are enabled. Therefore, the detection time and single cost of valid numbers will be higher than the activation detection.

Differences in business applicable scenarios

If all you want to do is add friends, activating data is enough - as long as the number is registered with Line, you can send friend requests by searching for the ID without the other party being online. But if you are sending private messages to groups (such as coupons, event notifications), you must use a valid number, otherwise a large number of messages will be sent to invalid accounts, resulting in a waste of resources and account risks.

Why does sending a message still fail after obtaining Line activation data?

Many operators started sending private messages immediately after purchasing “activation data” and found that the delivery rate was only 30%-50%. The reasons are as follows:

1. The user has deleted the account: The other party has uninstalled Line and not reinstalled it, or has canceled the account, but some cached data is still marked as “activated” during detection.
2. Long-term offline: If you have not logged into Line for several consecutive months, the system may have recycled your account or set it offline.
3. Blocked or banned: Although the account you searched for exists, the other party may have blocked you or prohibited non-friends from sending messages.
4. Official Banned: This number was once used for mass marketing and was officially banned by Line, but the basic registration record is still there.

Because of these circumstances, “opening” does not mean “being able to get it.” Valid number will filter out the above invalid situations through more stringent detection, so that the message can truly be delivered to the target user.

Analysis of applicable scenarios of Line activation data and valid numbers

Recruiting new members in the community and adding friends in batches

• Recommended to use Line to activate data: To add friends, you only need the other party’s account to exist, not the other party to be online. You can use activation data to initiate friend requests in batches and wait for the other party to pass. In this scenario, activating data is the most cost-effective.
• Operation Suggestions: First do a full activation test, generate a “Line user list”, and then add people in batches. If the other party fails to get through for a long time, you can contact them via private message again.

Private message marketing and active contact

• Must use a valid Line number: When sending a group private message, if the number is invalid, it will not only waste costs, but may also trigger Line’s anti-spam mechanism, causing the account to be blocked. Only valid numbers can ensure that messages are sent and read.
• Operation Suggestion: Based on the activation test results, conduct further “activity” or “validity” tests and screen out numbers that have recently gone online as marketing targets. For example, KK-DATA supports multiple detection types such as Line activated, Line valid, Line active, etc. The results are exported in CSV, and you can directly filter based on the exported field “active” or “valid”.

Gender/age targeted filtering

• Requires validity + Deep detection: Line gender detection is usually based on confirming that the number is valid or active, and then reading the gender field in the account information. Therefore, it belongs to the deep data of valid numbers and can provide two kinds of information at the same time: “This number is a valid user” and “This user is a male/female”. If you want to target men around 30 years old, you need to get a valid number first and then filter by gender/age field.
• Subject to the fields exported from the console: Different detection platforms have different accuracy rates for gender information, and the age field is generally an approximate estimate (not ID card level). Please refer to the platform documentation when using it.

How to determine whether you are getting Line activation data or a valid number?

After obtaining the data, quickly identify it based on the following three points:

1. Check the exported fields: If there are only fields such as “phone”, “registered” and “result” in the CSV, and the value is only “Y/N”, it is most likely activation data. If there are fields such as “active_last_7days”, “valid” and “online”, it means it is a valid or active detection.
2. Check the detection platform description: Formal detection platforms will clearly describe the meaning of each detection type in the document. For example, the KK-DATA document (https://docs.kkdata.cc/) will list the respective output fields of “Line activation detection”, “Line valid detection” and “Line gender detection”.
3. Sampling Verification: Randomly select 100 numbers, use your own Line account to send a test message, and record the delivery and failure ratios. If the failure rate exceeds 30%, it is likely that all you get is activation data.

Three points to note when choosing a Line data filtering solution

1. Detection depth: activated vs effective vs active

• Activation: Basic, suitable for adding friends;
• valid: suitable for private messages, guaranteed delivery;
• Active: Suitable for high response rate needs, such as users who have acted in the past 7 days. Choose the detection type based on your business goals.

2. Coverage area: Line’s main market share

Line is mainly used in Taiwan, Thailand, Japan, Indonesia and other countries. The quality of numbers in different regions is different: for example, Thailand has a lot of Line users, but there are also many zombie numbers; Japanese users have a high degree of real-name recognition, but the detection cost is slightly higher. It is recommended to give priority to detecting the main number segment of your target area to improve data utilization.

3. Balance between cost and data volume

• The price of effective detection is usually higher than that of activated detection (see the real-time price of the console for specific unit prices).
• If you only have a small budget, you can do activation testing first, randomly sample a small number of numbers from the results for effective testing and verification, and then increase the budget after confirming the data quality.
• Avoid recharging too much at one time to complete all tests, and leave enough balance for subsequent active screening.

The best practice path for Line activation data to a valid number

The ideal screening process is: Generate number → Full activation test → Perform active/effective screening in the activation results.

Specific steps:

1. Generate number list: Use a global number generation tool (such as KK-DATA’s number generation module) to batch generate mobile phone numbers according to target countries and number segments, or import numbers you have collected yourself. Generation costs are free.
2. Do Line activation detection: Submit the generated number to the Line activation detection task and obtain the “Activated” list. At this point you already have a list of Line users.
3. Filter valid/active from activation results: Export the “activated” numbers and then submit them to Line valid detection or Line active detection (the active window can be specified, such as the past 7 days, 30 days). This step will deduct fees on a per-item basis, but because only the numbers that have been activated are detected, the cost of invalid detection is saved.
4. Export target data: Export the final valid/active number to CSV or TXT for adding friends, private messages or importing into CRM.

This pipeline strategy can maximize the use of budget: first low-cost generation + activation detection to filter out a large number of invalid numbers, and then perform in-depth detection on the valid pool. The KK-DATA platform just supports this kind of concatenation - from number generation to multi-platform screening numbers, all steps are completed in one console, and the data can be connected directly without manual CSV conversion.

FAQ

**Q: What is the use of Line activation data? **

Answer: Line activation data is mainly used to confirm whether a mobile phone number has registered a Line account, and is suitable for scenarios with low reach requirements such as batch adding of friends and basic user portrait analysis. It cannot guarantee that the account is currently active and can send and receive messages.

**Q: Are Line valid numbers and Line active numbers the same concept? **

A: Not exactly the same. “Valid” usually means that the account exists and can receive messages, while “active” emphasizes that the user has been online/used in the near future. Different detection platforms have different definitions and field outputs. It is recommended to refer to the specific detection result fields exported by the console.

**Q: Will it be effective if I only buy Line activation data for private message marketing? **

Answer: The effect may not be ideal. There may be a large number of zombie accounts, deleted accounts or long-term offline users among the only activated numbers, so the actual reach rate is low. When targeting private message marketing, it is recommended to choose data with activity or validity detection.

**Q: Where can I get the real Line activation data and Line valid number detection? **

Answer: You can use a professional screening platform for batch testing. For example, KK-DATA supports multiple detection types such as Line activated, Line valid, Line gender, etc. The results are exported as CSV/TXT files. The specific detection types and fields are subject to the real-time configuration of the console.

**Q: Is Line gender detection activation data or valid number data? **

Answer: Line gender detection usually further analyzes the gender field in the account information based on confirming that the number is valid or active. Therefore, it generally belongs to deeper detection and can provide two types of information: “This number is a valid user” and “The user’s gender” at the same time.
