Key takeaways
- LINE OA sign-up is free: log in with a LINE Business ID, fill in the account form and confirm.
- Create the account on the web (LINE for Business → LINE Official Account Manager) if you plan to apply for a verified badge.
- Verification is requested after the account exists; LINE says review takes about 10 business days.
- Before you invite anyone, set up the profile, greeting message, rich menu, auto-responses and response hours.
- In week one, put your QR code everywhere customers already see you and give them a reason to add you.
To sign up for LINE OA, go to LINE for Business, choose to open an official account, log in with a LINE Business ID (your personal LINE or an email address), fill in the account form and confirm. It is free and takes only a few minutes once your details are ready. Use the web version if you want to apply for a verified (blue) badge later, then set up your greeting message and rich menu before you invite customers.
This guide walks through the LINE OA sign-up flow as described in LINE’s Thai help center, then covers verification, the settings to change first and a simple plan for your first week.
Before you start: what you need
- A LINE Business ID. This is your login for LINE’s business tools. You can create it with your personal LINE account or with an email address. Customers don’t see your personal profile.
- Your account name. Use the name customers know you by, such as your shop or brand name. It appears in chat lists and search results.
- Basic business details. The form asks for things such as your business type (industry) and contact email.
- A square profile picture (usually your logo) and a cover image.
How to sign up for LINE OA: step by step
On the web (recommended)
| Step | What to do | Notes |
|---|---|---|
| 1 | Open LINE for Business Thailand (lineforbusiness.com/th) | The official site; avoid look-alike links |
| 2 | Select “Sign up for an official account” (สมัครบัญชีทางการเลย) or “Open an official account” (เปิดใช้บัญชีทางการ) | |
| 3 | Log in with your LINE Business ID | Use LINE login or email |
| 4 | Fill in each required field, then select “OK” (ตกลง) | Account name, business type, contact details |
| 5 | Check the summary screen (ตรวจสอบรายละเอียด) and select “Finish” (เสร็จสิ้น) | Your account appears in LINE Official Account Manager |
In the LINE Official Account app
- Download the LINE Official Account app for iOS or Android.
- Choose to register and log in with LINE or with email.
- Tap “Create account” (สร้างบัญชี).
- Fill in the required fields and tap “OK”.
- Tap “Create account” again.
If you already manage an account, tap the menu (≡) at the top left, then “+ Create account”. The app is handy for answering chats on the go, but do the main setup on the web, where every feature is available.
Account limits
One Business ID can hold up to 100 LINE OA accounts in total, unverified and verified combined. Multi-branch businesses can use separate accounts per branch or one account with segments; choose based on who answers the chats.
How to request a verified (blue) badge
Every new account starts as an unverified account with a grey badge. It works fully, but it doesn’t appear in LINE search results. A verified account has passed LINE’s review, shows a blue badge and can be found in LINE search.
- When: after your account is created. Complete your profile first.
- Where: in LINE Official Account Manager, under your account settings, where you submit the verification request.
- Who can apply: LINE currently accepts verification requests in Thailand, Japan and Taiwan.
- How long: about 10 business days, sometimes longer. LINE says it can’t share status details during review.
LINE decides on each application and doesn’t publish a full list of approval criteria, so a complete, accurate profile that matches your real business gives you the best chance. If you also want a readable @ID instead of a random one, you can buy a Premium ID (an optional yearly add-on) in LINE Official Account Manager.
First settings checklist
Do these before you share your QR code. First impressions happen in the first message.
| Setting | What to set | Why it matters |
|---|---|---|
| Profile | Logo, cover image, short description, opening hours, address, phone | Customers check this before they chat |
| Greeting message | Thank them, say what you offer, give one clear next step (or a welcome coupon) | Sent automatically to every new friend; doesn’t use your message quota |
| Rich menu | 3–6 buttons for your top actions: book, menu or products, promotions, location, contact | Most customers tap the menu instead of typing |
| Auto-response | Keyword replies for common questions (price, hours, location, delivery) | Answers instantly; doesn’t use your quota |
| Chat | Turn chat on so your team can reply one-to-one | Needed if customers will message you |
| Response hours | Set the hours your team answers; use auto-response outside them | Tells customers when to expect a human reply |
| Admins | Add team members with the right roles instead of sharing one login | Safer and you can see who replied |
LINE Official Account Manager lets you use chat, auto-response and AI response together, so you don’t have to choose between a bot and a human. A common setup is: auto-response handles simple keywords at any time, and staff take over in chat during response hours.
Your first-week plan to get friends
A new LINE OA has zero friends. These steps work without any ad budget:
- Day 1: Add yourself and your team as friends, test the greeting message, rich menu and auto-responses on a phone.
- Day 2: Print the QR code for your counter, tables, receipts, packaging and business cards.
- Day 3: Add the LINE “Add friend” button or link to your website, Google Business Profile and social media bios.
- Day 4: Post on your Facebook, Instagram or TikTok explaining what customers get on LINE (faster answers, bookings, members-only offers).
- Day 5: Ask staff to invite customers at checkout, with a simple script and a reason such as a welcome coupon.
- Day 6–7: Check insights for new friends and blocks, then send your first broadcast, short and useful, to see how people respond.
Once friends start coming in, review which package you need. The free package includes 300 broadcast messages a month; the Basic and Pro packages add more.
