Complete Guide to Registering a LINE Official Account | From Zero to Live in Just 5 Minutes [2025 Illustrated]

Have you been wanting to create your own LINE Official Account but have no idea where to start?

The truth is, registering a LINE Official Account is far simpler than you might think.

In just 5 minutes, fill in a few basic details and you'll have your own dedicated business account, ready to start building connections with customers.

21 Million Users: Why LINE Official Accounts Are a Must-Have for Taiwanese Businesses

LINE has over 21 million active users in Taiwan, with a penetration rate of 90%.

That means almost all of your potential customers are already using LINE.

If you don't have a LINE Official Account yet, you're leaving a direct customer communication channel on the table. And the best part? Registration is completely free, with 200 free messages per month included.

Whether you run a physical store, sell online, work as a freelancer, or are building a personal brand, a LINE Official Account helps you build stronger customer relationships.

What You Need Before Applying

Prepare the following before you start — it makes the process go smoothly.

Required Materials

1. Email Address

• Used for registration and receiving notifications
• Recommended: use a business or brand-dedicated email
• Make sure you can receive mail (check your spam folder)

2. Mobile Phone Number

• Used for identity verification
• Must be able to receive SMS
• Taiwanese numbers recommended

3. Account Information

• Account name (Chinese characters allowed, up to 20 characters)
• Account ID: the system automatically assigns a random "basic ID" (letters and digits, e.g. @zrf9921n) that cannot be customised; a memorable branded ID requires purchasing a paid "Premium ID", which is also a prerequisite for applying for account verification
• Industry category (choose the closest match from the list)

4. Image Assets

• Profile photo (square format, recommended 640×640px or higher)
• Background image (optional, recommended 1080×878px)
• Supported formats: JPG, PNG

Pre-Registration Checklist

Before you begin, confirm the following:

• Email and phone are working
• You've decided on an account name (one that matches your brand)
• You have a brand logo or profile photo ready
• You know your industry category
• Set aside 10 uninterrupted minutes

Personal vs. Business Registration: What's the Difference?

⚠️ First, a common misconception: LINE Official Accounts do not have separate "personal" and "business" registration entry points — there is only one way to create an account. What the official documentation distinguishes is whether you already have a basic account (create the account and apply for verification in one go) or already have one (submit the verification request from the desktop admin console or OAV). The split is about existing accounts, not personal versus business.

The two profiles below describe what documents you have on hand and how smoothly a later verification request will go — they are not two different application flows.

Individual Operators (No Business Number)

Suitable for:

• Individual studios
• Freelancers
• Personal brand creators
• Small businesses without a registered company number

Advantages:

• Simple application process
• No company registration documents required
• Immediate activation upon completion

Limitations:

• A Verified Official Account (blue shield) is open only to specific industry categories, requires a purchased Premium ID, and requires company/commercial registration or a competent authority's incorporation document
• Some advanced features may be restricted

Registered Companies (With a Business Number)

Suitable for:

• Registered companies and businesses
• Organizations with a unified business number
• Brands that require official verification

Advantages:

• Supporting documents are already on hand, making a Verified Official Account (blue shield) application easier to assemble
• Boosts brand credibility
• Access to the full feature set

Required Documents:

• Unified business number
• Company registration certificate
• Authorized representative ID

Registration Comparison Table

Recommendation:

• If you have a registered company, your supporting documents are more complete, so a later Verified Official Account (blue shield) application will go more smoothly
• Individual operators should also just create the basic account first, and submit a verification request later if needed

How to Apply for Account Verification

Verified accounts display an official badge, boosting brand credibility.

Benefits of a Verified Account

1. Official Verification Badge

• Blue shield: Verified Official Account — requires a Premium ID and approval through the official review process; unlocks the ability to apply for sponsored stickers, LINE Beacon and similar features
• Green shield: Enterprise Official Account — requires a Premium ID and approval through the official review process; unlocks more advanced API features
• Displayed next to your account name, increasing trust
• From 1 April 2026, unverified basic accounts no longer show the old "grey shield" — they show no shield at all

2. Higher Search Ranking

• Appears higher in LINE Official Account search results
• Makes it easier for potential customers to discover you
• Increases organic traffic

3. Brand Protection

• Prevents others from impersonating your brand
• Ensures customers are adding the correct official account
• Reduces fraud risk

Enterprise Official Account (Green Shield)

Troubleshooting Common Registration Issues

Here are the 8 most common registration problems and how to solve them.

Issue 1: I'm not receiving the verification email

Possible causes and solutions:

Cause 1: Email went to spam

• Check your spam or promotions folder
• Add LINE's sending domains (line.me, linebiz.com) to your contacts or allowlist

Cause 2: Email was entered incorrectly

• Double-check the spelling of your email address
• Make sure there are no extra spaces

Cause 3: System delay

• Wait 5–10 minutes and check again
• Click "Resend Verification Email"

Cause 4: Inbox is full

• Free up space by deleting old emails
• Try again after clearing storage

Issue 2: The Premium ID I want is already taken

At account creation the system assigns a random "basic ID". A memorable branded ID requires separately purchasing a paid "Premium ID", and Premium IDs are unique — one already taken by another account cannot be purchased.

Alternatives:

1. Modify the ID slightly (add a number or underscore)

   • Original: @brandname
   • Modified: @brandname_tw or @brandname2025

2. Use the full brand name or abbreviation

   • Full: @lionfans_official
   • Abbreviated: @lf_service

3. Add a regional or industry indicator

   • Region: @brandname_taipei
   • Industry: @brandname_cafe

Reminder:

• A purchased Premium ID cannot be changed afterwards, so think it through before submitting
• Have a few backup options ready

Issue 3: Profile photo upload fails

Possible causes:

File too large

• File size must be under 10MB
• Use an online image compression tool (e.g., TinyPNG) to reduce the size

Unsupported format

• Only JPG and PNG are supported
• Convert other formats (e.g., GIF, BMP) to JPG or PNG

Wrong image dimensions

• Recommended: 640×640px or higher
• Must be square (1:1 ratio)

Unstable connection

• Confirm your internet is working
• Refresh the page and try uploading again

Issue 4: Phone number verification fails

Solutions:

1. Confirm your phone number format is correct

   • Taiwanese numbers: 09XX-XXX-XXX
   • No country code (+886) needed

2. Confirm your phone can receive SMS

   • Test by sending yourself a text
   • Make sure SMS blocking features are disabled

3. Wait a few minutes and try again

   • SMS can sometimes be delayed
   • Usually arrives within 5 minutes

4. Try a different number

   • Use a backup phone number
   • Temporarily borrow a family member's number for verification

Issue 5: Can't log into the backend after registering

Check the following:

1. Confirm you're using the correct login method

   • If you registered with a LINE account, log in with LINE
   • If you registered with email, log in with email

2. Confirm your password is correct

   • Watch for capitalization
   • Check if Caps Lock is on

3. Clear your browser cache

   • Try logging in using incognito mode
   • Or clear the cache and log in again

4. Switch browsers

   • Chrome or Safari recommended
   • Make sure your browser is up to date

Issue 6: Can I change my account name?

Yes before verification, but there is a 7-day cooling-off period — and once verified, it can no longer be changed.

Steps:

1. Log into the LINE Official Account Manager (desktop)
2. Click "Settings" → "Account Settings" → "Basic Settings"
3. Find "Account Name"
4. Click "Edit"
5. Enter the new name
6. Save

Note:

• Account name has a 20-character limit (no full-width characters, no emoji or special symbols, no exaggerated advertising language, and it cannot contain the words "Official Account")
• Once changed, it cannot be changed again for 7 days
• A verified account's name cannot be changed at all once approved
• The account ID cannot be changed (a custom one requires purchasing a paid Premium ID)

Issue 7: Can one person manage multiple accounts?

Yes!

A single email or LINE account can manage multiple LINE Official Accounts.

Use cases:

• Managing multiple brands
• Running multiple store locations
• Offering different product lines

How to switch accounts:

1. Log into LINE Official Account Manager
2. Click your account name in the upper right
3. Select "Switch Account"
4. Choose the account you want to manage

Issue 8: I selected the wrong industry category during registration

You can change it.

Steps:

1. Go to "Settings" → "Account Settings" in the backend
2. Find "Industry Category"
3. Click "Edit"
4. Select the correct category
5. Save

Impact:

• Industry category mainly affects system-recommended features and marketing suggestions
• It does not affect basic account functionality
• Can be changed at any time
