2026 LINE Registration Guide: How to Create a LINE Account and Fix Common Issues

LINE is a messaging app widely used in many countries and regions across Asia. In addition to text messaging, it supports voice and video calls, group chats, and sharing photos, videos, files, and stickers. For users who need to stay in touch with friends, customers, or teams overseas, LINE can be a convenient communication tool.

However, the LINE registration process is not the same everywhere. In some countries and regions, you can create a LINE account using a phone number and verify it by SMS or phone call. In other regions, LINE requires you to sign up with an Apple or Google account.

This guide explains how to create a LINE account and covers some of the most common registration problems and how to fix them.

Key Takeaways

• LINE is a messaging app that supports text messages, voice and video calls, group chats, and file and media sharing.
• The available registration method depends on your country or region. Some users can sign up with a phone number, while others need to use an Apple or Google account.
• A phone number used for registration must be able to receive verification messages. LINE also does not support certain numbers, including some virtual phone numbers.
• After creating a LINE account, you can set up your profile, add friends, and adjust notification and privacy settings.

1. What Is LINE?

LINE is a messaging app mainly used for private conversations, group communication, and voice and video calls. Users can send text messages, photos, videos, files, and stickers, as well as create groups for conversations with multiple people.

LINE also offers official accounts, stickers, and other content services. As a result, it can be used not only for personal communication but also for customer communication and other business-related purposes.

If you want to use LINE's messaging, calling, and other features, you first need to create a LINE account.

2. How to Sign Up for LINE

According to LINE's official help center , the available account creation methods vary depending on your country or region.

Currently, users in Hong Kong, Japan, South Korea, Taiwan, and Thailand can create a LINE account with a phone number, while users in other regions need to sign up with an Apple or Google account.

The same phone number, Apple ID, or Google account cannot be used to create multiple LINE accounts.

Sign Up for LINE With a Phone Number

If phone-number registration is available in your region, you can create a LINE account directly through the LINE app.

Follow these steps:

1. Open the LINE app and tap Sign up.
2. Select your actual country or region and enter your phone number.
3. Read and agree to LINE's Terms of Service and Privacy Policy.
4. LINE will send a verification code to your phone. Enter the code when prompted.
5. Enter a name and set a profile picture.
6. Create a password for your LINE account.
7. Choose whether to allow LINE to use your phone contacts to find friends.
8. Follow the remaining instructions to finish setting up your account.

The phone number you use must be able to receive verification messages. LINE does not support registration with numbers starting with 050 or virtual phone numbers, so a regular mobile number provided by a mobile carrier is recommended.

Also, if the phone number is already linked to another LINE account, using the same number to create a new account may affect the existing account. Before using an old number, make sure it is not already associated with another LINE account.

Sign Up for LINE With an Apple or Google Account

If the registration page does not offer a phone-number option, it does not necessarily mean that LINE cannot be used in your region.

In some countries and regions, LINE no longer offers phone-number registration. Instead, you need to select Continue with Apple or Continue with Google, sign in with your Apple or Google account, and follow the instructions to set up your name, profile picture, password, and other account details.

3. Common LINE Registration Problems and Solutions

Most LINE registration problems are related to the available registration method, verification codes, or existing account information.

Why Can't I See the Phone Number Registration Option?

This is usually related to your country or region.

LINE offers different account creation methods depending on where you are located. In some regions, phone-number registration is no longer available, so the registration page may only show options to continue with an Apple or Google account.

In this case, simply use the Apple or Google registration option provided on the screen.

What If I Don't Receive the LINE Verification Code?

If phone-number registration is available in your region but you do not receive the verification code, try the following:

• Make sure you selected the correct country or region.
• Check that the phone number is entered correctly.
• Check your mobile signal and SMS blocking settings.

If your phone cannot receive SMS messages but the registration page shows Call me instead, you can use phone verification. LINE will provide the verification code through an automated phone call.

However, phone verification is not available in every country or region. If the option does not appear, you will need to use the registration method currently supported in your region.

Why Does LINE Show "Welcome Back"?

If you see "Welcome back, XXXX!" after verifying your phone number, the number may already be associated with an existing LINE account.

If the displayed name does not belong to you, do not continue using that account. Instead, select:

No, that's not me → Next → No, create a new account

Then follow the instructions to create a new LINE account.

Why Can't I Complete LINE Registration?

If you cannot continue the registration process, check the following:

1. Check your region and registration method LINE offers different registration methods in different regions. If phone-number registration is not available where you are, use an Apple or Google account instead.
2. Check your phone number If you are registering with a phone number, make sure it meets LINE's requirements. Numbers starting with 050 and virtual phone numbers cannot be used for registration.
3. Make sure you can receive the verification code Check your mobile signal and SMS blocking settings. If phone verification is available on the registration page, you can also try that option.
4. Check the LINE app and your internet connection Make sure you are using an up-to-date version of the LINE app and that your current network connection can access LINE's services.

If none of these solutions work, check the LINE Help Center for additional guidance on account creation.

4. What Should You Do After Creating a LINE Account?

After creating your account, there are a few basic settings you can configure to make LINE easier to use.

Set Your Name and Profile Picture

You can set your name and profile picture during registration. If you want to change them later, you can do so from your profile settings.

If you mainly use LINE for work or customer communication, consider using a recognizable name and clear profile picture so that other users can easily identify you.

Add Friends

LINE allows you to add friends through contacts and other available methods. If you allow LINE to access your contacts during registration, LINE can use the phone numbers in your address book to find people who are already using LINE.

If you do not want to add contacts automatically, you can choose whether to enable this feature based on your needs.

Adjust Notifications and Privacy Settings

After registration, you can adjust your notification, friend, and other privacy settings.

If you mainly use LINE for work, it may be useful to configure notifications so that important messages are not missed. For personal use, you can adjust friend and notification settings according to your preferences.

Start Using LINE

Once the basic setup is complete, you can use LINE to chat with friends, participate in group conversations, and make voice and video calls.

If you plan to use LINE regularly, keep your account information up to date and make sure you have access to the information associated with your account. This can make it easier to continue using your account when changing devices or updating account settings.

How to Manage Multiple LINE Accounts?

If you need to use multiple LINE accounts, it is important to understand how LINE handles account creation and device usage. The same registration information cannot be used to create multiple LINE accounts, and using separate devices for different accounts makes account management easier.

Therefore, if you need multiple LINE accounts, you should prepare different registration information for each account and use the accounts in separate device environments.

Why Should Multiple LINE Accounts Be Managed Separately?

For example, if you need to manage five LINE accounts, you would need five sets of account registration information and separate device environments for those accounts.

Using physical phones for every account means purchasing multiple devices, installing LINE on each one, logging into each account, and maintaining all of those devices. As the number of accounts grows, device setup and daily management can become increasingly time-consuming.

This is where cloud phones can be useful. A cloud phone allows you to create multiple independent Android environments in the cloud, with each environment assigned to a different LINE account. This reduces the need to purchase a separate physical phone for every account and makes it easier to keep accounts separated.

How to Manage Multiple LINE Accounts With Cloud Phones

You can manage multiple LINE accounts by following a one account, one independent cloud phone environment setup. Using DuoPlus Cloud Phone as an example:

1. Create a Separate Cloud Phone for Each LINE Account

Start by creating multiple cloud phone environments based on the number of LINE accounts you need to manage.

For example, LINE Account A can be assigned to Cloud Phone A, while LINE Account B is assigned to Cloud Phone B. Keeping accounts in separate Android environments reduces the need to repeatedly switch between accounts.

2. Configure the Network Environment for Each Cloud Phone

Configure the appropriate network environment for each cloud phone based on your operational requirements.

Keeping each account associated with its corresponding cloud phone and network environment makes it easier to identify and manage different accounts.

3. Install the LINE App in Bulk

After creating multiple cloud phones, you can install the LINE app across the devices.

Compared with preparing physical phones one by one, bulk app installation can reduce repetitive setup work. When you need to add another LINE account, you can create a new cloud phone and complete the app setup there.

4. Register or Log In to LINE Accounts

Once the cloud phones and LINE app are ready, you can register or log in to the corresponding LINE accounts separately.

If phone-number registration is available in your region, you can use DuoPlus Cloud Numbers to provide a corresponding number for each account and complete the verification process according to LINE's registration requirements.

Keep in mind that LINE's registration methods vary by country or region. Some regions support phone-number registration, while others require an Apple or Google account. Always follow the registration options currently shown by LINE.

5. Manage Multiple Cloud Phones From One Workspace

Once the LINE accounts are set up, you can manage the corresponding cloud phones from a centralized workspace.

This allows each LINE account to remain associated with its own cloud phone environment while multiple devices can be viewed and managed from one interface. Compared with maintaining a large number of physical phones, this approach can be more practical when managing multiple accounts.

FAQ

1. Can I change the phone number linked to my LINE account?

Yes, but the exact process depends on your account and the options currently available in LINE.

If you need to change your phone number, first make sure the new number meets LINE's current requirements before updating the account information.

2. Can I use the same LINE account on multiple devices?

Yes, but the available options depend on the type of device and LINE's current account and device policies. The way LINE works across phones, computers, and other devices is not exactly the same.

If you are switching to a new primary device, make sure your account has been properly linked or transferred before making the change.

3. Can I choose any country or region when registering for LINE?

It is not recommended. You should select the country or region where you are actually located because LINE provides different registration methods depending on the region.

Choosing a region that does not match your actual location may affect the registration process or the options available to you.
