An unverified LINE Official Account can send messages, hold a rich menu and take orders perfectly well. What it cannot do is acquire anybody it does not already have. Paid friend acquisition is switched off at the product level in every market. Your account is also invisible in LINE’s in-app search, and most of the printed shop materials that drive walk-in adds are locked behind the same gate. If you have been trying to buy friends for weeks and the ad menu keeps refusing to appear, this is why, and it is not a bug.
Verification gets described in English as a trust badge, which makes it sound like a nice-to-have you get around to eventually. In acquisition terms it is closer to an ad account. Here is exactly what it turns on, what it costs in Japan, Taiwan and Thailand, how long the review takes, and the specific mistakes that get applications quietly rejected.

The paid channel that simply is not there
Friend add ads are the only self serve friend acquisition product LINE sells, and all three markets gate them behind verification independently.
Japan’s own LINE Official Account Manager manual lists the conditions for running 友だち追加広告. The account must be verified. A payment method must be registered. The account must be connected to an authenticated organisation in Business Manager. Certain industries are refused even when the account is verified, and accounts administered by an authorised sales partner are ineligible.
Thailand’s LINE for Business page for Gain Friends Ads is blunter. The menu only appears for a blue shield verified account. If you are looking at your Thai account wondering where the ads section went, it was never rendered.
Taiwan gates 加好友廣告 behind the blue shield certified account or the green shield enterprise account. Grey shield accounts have no route to it.
So the largest paid acquisition channel LINE offers is closed to an unverified account in all three markets, and it is closed at the product level. No amount of budget opens it.
People searching your brand name inside LINE will not find you
This is the loss that hurts more over time, and it is documented plainly in Japanese and almost nowhere in English. Users who type your account name or a keyword into the search field inside the LINE app will not see an unverified account in the results. Verified accounts appear in search by name, by category and by region.
What remains for an unverified account is ID search. Somebody has to already know your LINE ID and type it in exactly, which means they already knew the account existed, which means search was not doing any work for you at all. Every customer who hears your brand name from a friend and goes looking for it inside LINE hits nothing.
The posters and shop goods you cannot order
Offline collateral is where the difference shows up in a way nobody writes about in English. LINE’s friend add guide generates printable posters carrying a QR code, and the template choice depends on account status.
| Item | Unverified | Verified |
|---|---|---|
| Poster templates | Simple Green only, one design, no LINE characters | Simple Green, Green and White, three designs, with licensed LINE characters |
| Physical novelty goods (triangle POP for counters, window stickers, shop cards) | Cannot order | Can purchase |
| Invoice payment through the Paid service | Not available, card only | Available |
| Membership feature and free-response survey answers | Not available | Available |
If your acquisition plan involves a counter in a Bangkok mall or a Taipei storefront, that middle row is the whole plan. The triangle POP sitting next to a till is the cheapest friend you will ever get, and an unverified account cannot buy one.
What verification costs in each market
This is where the advice you find in English falls apart, because it is almost always written about Japan and then repeated as though it were universal. It is not.
| Market | Cost to become verified | Review time | Notes |
|---|---|---|---|
| Japan | Free. Verified and unverified accounts sit on identical pricing plans | 5 to 10 business days | Longer during busy periods |
| Thailand | ฿888 one-time, excluding VAT, valid for the life of the account | 7 business days for review, roughly 1 day to upgrade after payment | Blue shield |
| Taiwan | Bundled with a premium ID purchase, NT$720 per year excluding tax through a browser, NT$1,038 per year if bought inside the iOS app | Not published. Progress is notified by email and LINE message with a tracking link | Blue shield. The green shield enterprise account is by LINE invitation and carries no fee |
Two things in that table deserve a second look. Japan charges nothing, which is genuinely unusual and means there is no financial reason to delay. Taiwan is the market where verification is not free, because the blue shield is tied to buying a dedicated premium ID on an annual subscription, and the price differs depending on whether you buy through a browser or through Apple’s in-app purchase. Buy it in a browser.
What the review actually asks for
Thailand asks for business documentation appropriate to your sector, such as DBD registration, a clinic licence or TAT certification for tourism, along with verified contact details and personal details for whoever is applying. Taiwan publishes a table of required supporting documents by industry type. Japan checks that the information on your application matches what is on your website and your other public profiles, including the representative’s name and the registered business name.
That last point is the one foreign operators trip over. Your Japanese landing page, your company registration and your LINE application all have to agree with each other, and if your legal entity is registered in Singapore while your LINE account claims a Tokyo shop, that mismatch is enough on its own.
Why applications get rejected, and why nobody tells you
Japanese sources agree on the common causes, and they are unglamorous:
- Errors in the application form itself. Putting the LINE ID where the account name goes, using a personal name instead of the registered business name, or entering contact details that do not resolve.
- Inconsistent information across your own properties. Website, social profiles and application must state the same business name and the same representative.
- Operating in a category LINE refuses. Dating services, adult entertainment, multi-level marketing and certain sales methods will not pass, and in Japan some industries stay barred from friend add ads even after the account itself is verified.
- Failing the published review standards, which are deliberately not disclosed in detail beyond a requirement not to harm users, break the law or damage LINE’s reputation.
Now the part that catches everyone. LINE states it has no obligation to explain the result of a review or the reasoning behind it. You get a decision and nothing else. Resubmitting the same application unchanged is therefore a waste of another 5 to 10 business days, and the only sensible response to a rejection is to audit your own consistency before reapplying.
So the standard advice holds up neatly. Verification is free in Japan, cheap everywhere else, and there is no reason not to apply on day one.
Which is true right up until you are rejected without a reason, at which point free stops being the relevant number and the ten business days you cannot advertise in becomes the number that matters. Get the application in months before you think you need it.
Japan changed the badges in April 2026
If you are working from an English blog post with badge screenshots in it, check the date. On 1 April 2026, with the iOS rollout following from 7 April, LINE redesigned verification badges for the Japanese market. Verified domestic accounts moved from the old star-and-shield mark to a green check mark. The unverified account badge was abolished, and so was the separate premium account designation.
The practical effect for a foreign operator is that Japanese screenshots older than April 2026 show a badge system that no longer exists, including the navy shield that used to mean verified in Japan.
The badge colours mean different things in different markets
This is a genuine trap, and it has caused more than one operator to conclude their account was already verified when it was not.
| Market | Unverified | Verified | Enterprise or premium |
|---|---|---|---|
| Japan, from April 2026 | No badge at all | Green check mark | Designation abolished |
| Japan, before April 2026 | Grey shield | Navy shield | Green shield |
| Thailand | Grey shield | Blue shield | Green shield, premium |
| Taiwan | Grey shield | Blue shield | Green shield, by LINE invitation |
Green means verified in Japan today. Green means enterprise in Taiwan and Thailand, and a Taiwanese or Thai account showing green got there by invitation rather than application. If you manage accounts across more than one market, check the status inside account settings and ignore what the shield looks like.
The order to do this in
- Apply for verification before you build any acquisition plan, because the review window is longer than most campaign lead times and costs nothing in Japan.
- Make your business name, representative name and contact details identical across your website, your public profiles and the application, in that market’s language.
- In Taiwan, buy the premium ID through a browser rather than the iOS app and save NT$318 a year.
- Once the badge lands, check that the friend add ads menu has appeared before you commit budget, since Japan additionally requires a registered payment method and a Business Manager organisation link.
- Only then order posters and counter goods, because the verified templates and the physical novelty items are not available to you until the review passes.
