Complete Guide to LINE Official Account Customer Support | How to Resolve Any Issue Fast [2025 Updated Contact Channels]

Running into a problem with your LINE Official Account but don't know who to turn to?

Many people assume there's a customer service hotline — then spend hours searching for a number, or worse, get scammed in the process.

The truth is, LINE Official Account support is quite comprehensive. Use the right channels, and your issues can be resolved quickly.

Who Do You Contact for Technical or Billing Issues on LINE Official Account?

Running a LINE Official Account means eventually encountering problems:

Technical issues: Can't log in, features not working, messages failing to send.

Billing issues: Unclear charge details, wanting to change payment method, questions about fees.

Operational issues: Not sure how to set up a feature, can't find a particular option.

Without knowing the right channels, you can waste hours — and if a problem goes unresolved, it can impact your business operations.

Even more critically, there are many fake "LINE customer service phone numbers" circulating online that are actually used by scammers. Knowing the official support channels protects you from being defrauded.

This guide covers every support channel available for LINE Official Account, how to file an effective issue report, self-service troubleshooting for common problems, and how to track a submitted request.

Phone Support: What You Need to Know

There's an important clarification to make here.

Important Warning: There Is No Phone Support in Taiwan

Please note: LINE Official Account does NOT provide phone customer support in Taiwan.

Common Scam Tactics:

Searching online for "LINE customer service phone number" will return many results, but these are:

• Fake numbers used by scammers
• Unofficial paid services (charging high fees)
• Other companies offering LINE-related services (not LINE itself)

Real Example of a Scam:

Scam script:
"Hello, this is the LINE Customer Service Center. Your account has shown
unusual activity. You need to provide a verification code to resolve this..."

Result: account stolen, personal information leaked, financial loss

How to Identify Scams:

LINE's official team will NEVER:

• Call you proactively
• Ask you for a verification code
• Ask you for your password
• Ask you to make a payment or transfer money

The correct approach:

• Use the official channels described in this article
• Log into the official website to find answers
• Contact support through the Issue Reporting System

Bottom line: In Taiwan, if you have a LINE Official Account problem, use online channels. Do not trust any "customer service phone number" you find online.

How to Speed Up Support and Track Your Request

LINE does not publish response-time or satisfaction figures for its support channels, and actual waiting times vary by issue type. Rather than guessing how long it will take, put the effort into giving complete information the first time.

Tips for Faster Resolution

Tip 1: Use the right channel Match the issue type to the right channel for faster handling.

Tip 2: Provide complete information upfront Give all relevant details on the first contact to avoid back-and-forth.

Tip 3: Use self-service resources first Many issues are already answered in the Help Center — check there before filing a ticket.

Tip 4: Track your ticket number Keep the ticket number on hand for progress checks or follow-up.

Tip 5: Set realistic expectations Non-urgent issues typically take several business days — don't expect an immediate reply.

If Support Still Hasn't Replied

If you still haven't heard back after a while:

1. Log into the backend and check "Issue Reporting History"
2. View the ticket status (In Progress / Replied)
3. If several days have passed with no response:
4. Resubmit the issue, noting "Second Submission" in the description
5. Or contact through an alternate channel (LINE Business website)
