# Phone Number for LINE Verification

Source: https://tempsmsverify.com/temp-number/line · Last updated: 2026-10-24

LINE offers phone-number sign-up only in five markets: Japan, Taiwan, Thailand, Hong Kong and Korea. A phone number for LINE from one of those markets lets you receive the code online, and TempSMSVerify charges you only if the SMS arrives.

## Can I use a temporary phone number for LINE?

Sometimes. LINE allows phone sign-up only in Japan, Taiwan, Thailand, Hong Kong and Korea, and says it rejects some virtual numbers. If the catalog has stock for one of those countries, TempSMSVerify can receive the 6-digit LINE code. If LINE never sends it, your balance is refunded automatically.

## Steps

1. **Check your sign-up screen.** Open LINE and see whether it asks for a phone number or offers Apple and Google sign-in.
2. **Top up.** Add at least $5 with Card via Stripe (Visa, Mastercard, Amex, Apple Pay, Google Pay); Crypto (USDC or SOL on Solana). There is no subscription.
3. **Buy a LINE number.** Pick LINE and a supported country such as Japan or Thailand if the catalog shows stock.
4. **Enter the number and wait.** Choose the matching country in LINE, paste the number and request the SMS once.
5. **Enter the 6-digit code.** Type the code right away, then add an email and password under Settings > Account.

## How the LINE verification code works

In the regions where LINE uses phone sign-up, the app texts a 6-digit verification code to the number you enter. The code is valid only for a short time, so LINE's help center tells you to enter it right after it arrives. If the text does not come, a 'Call me instead' link reads the code by voice.

TempSMSVerify receives SMS only, so stick to the text message. The voice option will not show up in your dashboard.

## LINE's region rule for phone sign-up

LINE's help center lists the countries where phone verification applies: Hong Kong, Japan, Korea, Taiwan and Thailand. It asks for a number from a mobile provider in one of those markets. In most other regions, the sign-up screen offers 'Continue with Apple' or 'Continue with Google' instead of a phone number.

LINE also says it does not accept landlines, data-only SIMs, Wi-Fi-only devices and some virtual numbers. Our lines come from mobile number providers, but LINE makes the final call. If it declines a number, no SMS is sent and you get your money back.

- Need LINE for a Japanese or Thai business contact? Check the catalog for Japan or Thailand stock first.
- Outside those markets, signing up with Apple or Google is usually simpler than a phone number.
- LINE lets one phone number, email, Apple ID or Google account sit on only one LINE account at a time.

## Phone number for LINE: errors and fixes

LINE's attempt limit is strict. Its help center says the waiting period after too many attempts cannot be lifted, even by support.

| Message or problem | What it usually means | What to do |
| --- | --- | --- |
| No phone number option | Your region signs up with Apple or Google | Use Apple or Google sign-in, or a number from a supported market |
| Verification code not received | LINE has not sent the SMS, or rejected the number | Wait a few minutes. Cancel after about 2 minutes for a refund |
| Please wait XX day(s) then try again | Too many phone verification attempts | Wait the full period. Support cannot remove it |
| Code expired | The short validity period ran out | Request one new code and enter it immediately |
| This number cannot be used | LINE declined the number type or range | Cancel and try another supported country |

## Pay only if the LINE code arrives

When you buy a LINE number, TempSMSVerify freezes the price in your balance. The charge goes through only when an SMS reaches the number. If LINE never texts the code, the full amount returns to your balance automatically. You can cancel once the button unlocks after about 2 minutes.

The number is reserved for up to 20 minutes. Before it lapses, register an email and password in LINE under Settings > Account, so you can log in on a new phone without a fresh SMS.

## Use LINE numbers responsibly

Use TempSMSVerify only for LINE accounts that belong to you, and follow LINE's Terms of Use. Spam, scams, fake official accounts and returning after a suspension break LINE's rules and ours. Read our Acceptable Use Policy at /acceptable-use before you buy.

## FAQ

### Does LINE accept virtual phone numbers?

LINE's help center says some virtual numbers cannot be used, along with landlines and data-only SIMs. TempSMSVerify numbers come from mobile number providers, but acceptance is LINE's decision. If LINE declines the number and no SMS arrives, you cancel after about 2 minutes and your frozen balance is refunded in full.

### Why doesn't LINE ask me for a phone number?

LINE offers phone sign-up only in Hong Kong, Japan, Korea, Taiwan and Thailand. In other regions, the app shows 'Continue with Apple' or 'Continue with Google'. If that is what you see, a phone number is not needed at all, and buying one would not help you register.

### How many digits is the LINE verification code?

LINE sends a 6-digit code by SMS. It is valid only for a short time, so enter it as soon as it appears in your TempSMSVerify dashboard. If you request a new one, use only the newest code. Too many requests can lock phone verification for a number of days.

### What does 'Please wait XX day(s) then try again' mean on LINE?

It means too many phone verification attempts were made. LINE's help center says this waiting period cannot be removed, even by contacting support. Stop requesting codes, wait the full period, and in the meantime cancel any TempSMSVerify number that did not receive a text so your balance is refunded.

### Can I use one number for two LINE accounts?

No. LINE allows a phone number, email address, Apple ID or Google account on only one LINE account at a time. Registering the number on a new account removes it from the old one. Add an email and password to your LINE account so it does not depend on the temporary number.

### Will my LINE account stop working when the number expires?

No, not while you stay logged in on the same phone. The risk is a new device or reinstall that asks for an SMS on the old number. Register an email and password in LINE, back up your chats, and move to a number you own if LINE is your main app.
