A LINE business account is a LINE Official Account. You create it for free with a LINE Business ID, and you pay only when you send more messages than your plan includes.
LINE is where many customers in Japan, Thailand and Taiwan ask about prices and bookings. LY Corporation reports 100 million monthly users in Japan, 54 million in Thailand and 22 million in Taiwan at 31 March 2026.
This guide shows how to create the account, how account types and IDs differ, what each market charges, and how to connect LINE to SleekFlow.
What is a LINE business account?
A LINE business account is officially a LINE Official Account, a business profile on LINE. Customers add it as a friend and message you like any contact. Businesses use it to reply one to one, send messages to many friends, and connect the Messaging API so tools such as SleekFlow can send and receive for them.
LINE says companies from large corporations to single stores use these accounts. You can run one from a computer or from the LINE Official Account app.
What types of LINE Official Account are there?
The types depend on your market. Thailand and Taiwan list three: general, verified with a blue shield, and a green-shield type for large brands. Japan lists two, unverified and verified, with a green badge. LINE says unverified and verified accounts have largely the same basic features, and the badge shows that LINE reviewed you.
In Thailand, a verified account needs a business in a category LINE accepts, a matching account name and supporting documents.
It then becomes searchable in LINE and on Google. Since 1 April 2026, general accounts in Taiwan show no shield, where they once showed a grey one.
What is the difference between a Basic ID and a Premium ID?
Every account gets a free Basic ID, a random string after the @ sign. A Premium ID is a name you choose, such as @line_cafe. It costs USD 12 a year on LINE's page for other regions, THB 444 a year in Thailand when you buy on Android or the web, and as little as NT$2 a day in Taiwan, per LINE Taiwan. LINE doesn't sell Premium IDs in the EU, Indonesia, Singapore or the US, and Japan's Premium ID fee changes on 1 December 2026.
You can't create a duplicate ID.
You also can't change a Premium ID once you buy it, so choose with care. To change it, you cancel and buy a new one. If customers will type your ID or see it on a poster, a name you chose is easier to remember than random characters.
Is a LINE business account free?
Creating the account is free, and every plan includes free messages each month. You pay for plans with larger allowances, or for extra messages on the highest plans. Prices differ by market, and LINE counts one message for each person it reaches.
Which messages count toward your quota?
Broadcast, push, multicast and narrowcast messages count toward your plan. Reply messages don't.
LINE Taiwan also lists welcome messages, one-to-one chat, auto-replies and AI auto-replies as free. Messages to users who blocked you aren't counted. When you hit your limit, the messages aren't sent.
In other words, answering customers who message you doesn't use your quota. Marketing to them does.
What do the plans cost in each market?
LINE changes prices often, so check your market's page before you budget.

How do you create a LINE business account?
To create a LINE business account, open LINE's Create a LINE Official Account page, sign in with a LINE account or sign up with an email address, fill in the entry form and confirm it. Then log in to LINE Official Account Manager to finish. LINE recommends a computer, and the account is free to create.
What do you need before you start?
You need a LINE account or an email address for your LINE Business ID, your business details for the entry form, and a computer or a phone. LINE prefers a computer. Check your country first, because LINE Official Account isn't available in the EU.
What are the steps?
Creating the account takes 5 steps: open the sign-up page, log in or sign up for a LINE Business ID, fill in the account form, confirm it, and finish in LINE Official Account Manager. Phone users follow the same flow in the LINE Official Account app.
Go to LINE's Official Account sign-up page and select Create a LINE Official Account.
Choose how to log in. With a LINE account, enter the email and password of your personal LINE account or scan the QR code with the LINE app. With email, enter your address and select the sign-up link LINE sends you.
For an email sign-up, open the email titled "Your signup link for LINE Business ID" and select Continue. Register your name and password, agree to the Terms of Use and Privacy Policy, then select Sign Up and confirm your details.
Fill in the required fields for your official account, check the Terms of Use and confirm what you entered.
Log in to LINE Official Account Manager to finish creating the account.
On a phone, download the LINE Official Account app, sign in or sign up with LINE or by email, then select Create an account and fill in the same details. If you sign in with the LINE app for the first time, LINE asks for a verification code.
What should you set up after the account is live?
After the account is live, open LINE Official Account Manager and set up your profile, your welcome message and your replies, then check your plan. Customers can add your account by scanning a QR code or opening a link, and you create both in LINE's manager, so share them where your customers already are.
Check the plan against your sending. A broadcast to 10,000 friends uses 10,000 messages, so a free allowance of a few hundred runs out fast.
How do you connect LINE to SleekFlow?
To connect LINE to SleekFlow, enable the Messaging API in LINE Official Account Manager, copy SleekFlow's webhook URL into LINE, then copy your Channel ID, Channel Secret and Basic ID back into SleekFlow. You need Admin access in SleekFlow, and you can connect one LINE Official Account to each SleekFlow account.
