Many users encounter issues shortly after registering a new LINE account, such as account restrictions, being unable to add friends, or even getting banned. In most cases, this is not accidental. LINE has a strict risk control system that evaluates whether an account shows abnormal behavior.
Therefore, if you want to use LINE accounts reliably in the long term, it is important to understand why new accounts are easily restricted and how to properly warm up a LINE account. This article explains the latest LINE account warm-up strategies for 2026, covering ban reasons, preparation steps, practical operation methods, and how to determine whether the warm-up process is successful. These practices can help significantly reduce the risk of account restrictions.
I. Why Are New LINE Accounts Frequently Banned?
Many users find that their new LINE account quickly becomes restricted, unable to add friends, or even permanently banned. In reality, LINE operates a strict risk control system. If the system detects unusual activity or a high-risk environment, it may trigger restrictions or suspension.
Below are the most common reasons new LINE accounts get banned.
1.Unstable registration IP environment
If the IP address frequently changes during registration or login, or if shared proxies and free proxies are used, the platform may classify the activity as suspicious and trigger risk control.
2.Abnormal device environment
If multiple LINE accounts are registered or logged in on the same device, or if emulators or cloud phones are used, the system may identify the activity as abnormal.
3.Excessive activity from a new account
If a newly registered account quickly adds many friends, sends a large number of messages, or joins many groups in a short time, it may be identified as a marketing or spam account.
4.High-risk phone numbers
Using virtual numbers, SMS verification services, or phone numbers that have already been used to register multiple accounts can increase the likelihood of restrictions.
5.Behavior unlike a real user
Examples include incomplete profile information, repeatedly sending identical messages, or adding large numbers of strangers within a short time. These behaviors significantly increase the risk of account suspension.
To reduce the risk of bans, the key is maintaining a stable environment and natural user behavior.
II. Preparation Before Warming Up a LINE Account
Before starting the LINE account warm-up process, it is recommended to prepare a stable registration environment. Many accounts are banned not because of incorrect operations but because the device environment, IP address, or phone number already carries risk signals.
If the initial setup is not handled properly, it will be easy to trigger the platform’s risk control even if you carefully warm up the account later.
Therefore, it is recommended to complete the following preparations before registering a LINE account.
1.Prepare a clean device environment
LINE can detect device information such as system version and device fingerprint. To reduce risk, it is recommended to:
● Use one device for one account whenever possible
● Avoid frequently switching between multiple LINE accounts on the same device
● Use an Anti-detect browser to create independent device environments
● Ensure the system, timezone, and language match the IP location
These measures make the account environment appear more like that of a real user.
2.Use a stable IP address
The IP environment is another key factor in LINE’s risk control system. If an unstable network is used during registration or login, such as frequently changing IP addresses or public proxies, the platform may trigger security checks.
To maintain a stable environment, it is recommended to:
● Use a dedicated static residential proxy
● Bind each account to a fixed IP
● Keep the login location consistent with the registration location
For example, you can obtain stable, clean, and exclusive proxy resources from IPFoxy and configure them in the account registration environment. Compared with public proxies, IPFoxy residential proxy services provide higher IP quality and reliability, making them less likely to trigger platform risk control.
It is also important to note that different platforms apply different levels of IP risk control, which means the required proxy type may vary, such as native vs. non-native IP or dual-ISP vs. single-ISP networks. It is recommended to conduct small-scale testing first and expand usage after confirming stability.
At the same time, you can verify the IP environment through IP detection tools. Using IPFoxy as an example, you can check:
● Whether the IP geolocation matches the expected region
● Whether the IP belongs to a real residential network
● Whether the IP risk score appears normal
3.Prepare a reliable phone number
LINE registration requires phone verification. If the phone number has been used repeatedly for registrations or comes from SMS verification platforms, the risk level will be higher.
Recommendations include:
● Use phone numbers that have never registered a LINE account
● Avoid numbers that have been verified multiple times
● Use long-term stable numbers instead of automated SMS platforms
In simple terms, the core of LINE account warm-up is maintaining a stable environment for device, IP, and phone number.
III. LINE Account Warm-Up SOP: 14-Day Strategy for New Accounts
After registration, a new account should gradually increase its activity level rather than performing large numbers of actions in a short time.
Days 1–3: Complete account information
Do not rush to add friends or send messages immediately after registration. First complete the basic account information to make the account look more authentic.
Recommended actions:
● Upload a profile photo
● Set a nickname and bio
● Browse friend posts or official account content
The focus during this stage is to increase account credibility and avoid any marketing activity.
Days 4–7: Begin normal interactions
After using the account for several days, you can start simple interaction behaviors such as adding a few friends and having casual conversations.
Recommended actions:
● Add 2–3 friends per day
● Engage in simple chats
● Send emojis or stickers
Avoid adding too many friends within a short period, as this may trigger system restrictions.
Days 7–14: Gradually increase activity
If the account operates normally after about a week, you can gradually increase usage frequency.
You can try:
● Moderately increasing the number of friends
● Joining group chats
● Making voice or video calls
However, you should still avoid bulk friend requests, mass messaging, or sending large numbers of links.
Overall, the core principle of warming up a new LINE account is gradual activity combined with natural user behavior. After about 7–14 days of normal usage, account stability usually improves significantly and the risk of suspension decreases.
IV. How to Tell If LINE Account Warm-Up Is Successful
Many users ask an important question during the warm-up process: when can the account be considered stable?
Generally, if the account operates normally for a period without triggering restrictions, the warm-up process can be considered successful. You can identify this through several signals.
- Adding friends is no longer restricted and acceptance rates improve.
- Messages send normally, including chats, images, and stickers.
- Login verification occurs less frequently when using the same device and IP.
- The account can join group chats without limitations.
Under normal circumstances, maintaining natural usage for 7–14 days will significantly improve account stability.
V. FAQ
A LINE account usually supports simultaneous login on a phone and a computer. However, frequently switching between multiple devices may trigger security checks.
If additional verification appears every time you log in, it usually indicates an unstable login environment. Keeping a fixed device and stable network environment can reduce these security checks.
Using a stable proxy typically does not cause account bans. On the contrary, a consistent IP environment helps maintain a stable login environment and reduces the probability of triggering risk control.
Summary
In most cases, new LINE accounts are banned due to unstable IP environments, abnormal device environments, risky phone numbers, or excessive activity in a short period.
To reduce the probability of bans, the key is to build a stable environment from the beginning and warm up the account gradually with realistic user behavior.
