Virtual Number for LINE Verification

Heading to Japan, Thailand or Taiwan? Everything there runs on LINE. Register an account on a virtual number before you land — from $0.50, code in seconds.

East Asia runs on LINE — be ready for it

Reservations, tours, landlords, language exchanges: in LINE's home markets, "do you have LINE?" is the first question. Here's how to answer yes, privately.

Set up before you fly

Register from home with a virtual number and land with a working LINE account — ready for airport pickups, hotel chats and restaurant bookings from day one.

A local-life account for expats

Living in Tokyo or Bangkok? Keep your home LINE untouched and run daily life — deliveries, schools, neighborhood groups — on a dedicated second account.

Friend-suggestion privacy

LINE suggests friends from phone contacts in both directions. A dedicated number keeps casual acquaintances — and their entire contact books — away from your profile.

Set up in 3 steps

1

Get a number

Buy a LINE-ready number in your dashboard — temporary for a trip, permanent for expat life.

2

Enter it in LINE

Use the number at LINE registration instead of your personal one.

3

Receive the code

The verification SMS arrives in seconds. Enter it, add your first contacts, done.

💡 Changing phones? LINE transfers via the number. LINE's account transfer to a new device re-verifies the registered number by SMS. With a one-time temporary number that's expired, the transfer fails and the account is stuck on the old phone. If your LINE account matters beyond one trip, use the permanent O2 SMS eSIM ($9.87/30 days).

LINE verification FAQ

Can I register LINE without my real phone number?

Yes. LINE requires a phone number at signup, but it doesn't have to be your personal one. Buy a number in your eSIMfly dashboard, enter it in LINE, and the verification code arrives within seconds.

Does LINE accept virtual numbers?

LINE blocks most VoIP ranges at registration. eSIMfly temporary numbers come from real carrier ranges in 50+ countries, and the permanent option is a genuine UK mobile on the O2 network - both pass LINE's checks reliably.

Why do travelers to Japan and Thailand need LINE?

In Japan, Thailand and Taiwan, LINE is how everything communicates - restaurants take reservations on it, tour guides coordinate on it, landlords and language schools expect it. Visitors without LINE hit real friction; a virtual number gets you an account before you land.

Is LINE tied to the number like WhatsApp?

Partly. LINE verifies by number at registration and uses it for account transfers between phones - but day-to-day login works via the app itself and your email/password. For an account you'll keep long-term, the permanent O2 SMS eSIM ($9.87/30 days) makes phone-change transfers painless.

Can I keep my home LINE account and add a second one?

LINE allows one account per device per number - so a second account needs a second number (and technically a second device or LINE's business tools). Many expats keep their home account and register a local-life account on a dedicated number.

How fast does the LINE code arrive?

Within seconds. LINE sends the SMS immediately and it appears in your eSIMfly dashboard or on your eSIM in real time. Registration takes about two minutes.
