Verify Your LINE Account Without Using Your Personal SIM

Quick walkthrough: a LINE SMS code on NumberFlare

If your wallet is already funded, skip straight to step three.

1. Create an account with an email address and enter the 6-digit code from your inbox.
2. Top up the USD wallet with a card or with USDT/USDC. Prices become visible after the first top-up.
3. Go to Instant OTP, type LINE in the service search, and select a country.
4. Confirm the purchase. The number appears, and its 20-minute window starts.
5. Open LINE, choose to create a new account, and enter the number.
6. When LINE says it has sent a code, switch to the NumberFlare inbox and wait for the SMS.
7. Enter the code in LINE and carry on setting up your profile.

No code, no charge: if the 20 minutes run out without a message, your wallet is refunded.

How do I enter a foreign number in LINE correctly?

Many failed attempts come down to formatting. LINE shows a country selector next to the phone field. Pick the country that matches the number you bought, and then type only the national part of the number.

• If the number you copied starts with a plus sign and the country code, leave that part out of the phone field.
• In some countries a domestic number starts with a zero. Once the country code is set, drop that zero.
• Check the last few digits before you tap to send. A single typo sends the code to someone else, and the attempt is wasted.

When LINE asks how to deliver the code, choose SMS. Whatever wording the message uses, only the digits matter.

Where can I get a LINE number?

Instant OTP for LINE is currently available in 197 countries. LINE is a major messaging app in Japan, Taiwan, and Thailand, and it also has users in Indonesia. Beyond those markets, the list includes the United States, Canada, the United Kingdom, Australia, Hong Kong, Singapore, Malaysia, the Philippines, Vietnam, South Korea, and Germany.

Choose based on where you, your friends, or your customers are. A shop owner who sells to buyers in Bangkok may want a Thai number, while someone in Osaka testing their own app's LINE login would pick Japan. Each country carries its own price, which you see before you confirm.

The LINE code never appeared. Now what?

Start with the simple checks, then move on:

• Wait it out. The window is 20 minutes, and the occasional message is slower than usual.
• Look at the country selector again. A wrong country turns your number into a different one.
• Check that LINE chose SMS. If the app offered another way to verify, go back and request a text message.
• Accept that some numbers are declined. LINE, like other apps, may refuse a virtual number or a particular number range.

If the window ends without a code, the charge is reversed to your wallet. Waiting a while before trying a new number, or picking a country closer to your situation, are the usual next steps.

Why does LINE keep my phone number on file?

LINE uses your number to create the account and confirm that it belongs to you. After that, the number keeps a role in a few situations:

• Moving to a new phone. Transferring a LINE account to another device generally involves verifying the phone number again, often together with your password or other details you set up.
• Logging back in after reinstalling the app.
• Finding friends. If you allow it, people who have your number in their contacts can find your account.

The first point matters most. Your chat history, the stickers you bought, and the official accounts you follow all sit on that LINE profile, and a lost number can make the move to a new phone much harder.

When should a LINE account live on a Cloud Number?

If the LINE account is for your business, your customer support, or simply your main personal profile, use a number you will still have when you change phones. A Cloud Number from $1.95/month does that: it stays yours while it renews, collects SMS in the dashboard inbox, and lets you make and answer calls in your browser, forward calls to a mobile, and keep voicemail.

Instant activation is available for numbers in the United States, Canada, and Puerto Rico. For Japan, Thailand, or any other country, request the number from the dashboard. Our team confirms whether it is available, the price, and whether local regulations call for an address or ID check before activation; how long that takes depends on the country. Instant OTP remains the better choice for a single code, such as checking your own app's LINE login on a test device. Details are on the pricing page.

Fair use of LINE with a second number

Use a NumberFlare number for LINE to protect your personal number, to keep a business account separate, or to test something you built. Keep to LINE's terms of use, run one account per real person or business, and never use a second number to replace a banned account or to sign up in bulk.
