6 tips on opening a LINE Ads account

Before you can use LINE for advertising, your account and connected assets go through a rigorous review process. This includes not only ads and their content (text & creatives) but also the account itself. In this article we have a look at 6 things that may cause your ad account to fail the verification process, and what can be done to avoid it.

Before you start

In order to be able to promote a business on LINE, advertisers must go through multiple steps which include ad account application, campaign set up, and payment method registration– all of which can be completed online. The initial set up process has been simplified and made available to businesses of all sizes, catering to a wide range of advertisers’ needs. However, an increasing number of applications are being rejected due to mistakes in the information provided during the application process.


Step 1


Get a LINE Business ID

The LINE Business ID verification system allows users to log into the various services provided by LINE. It can be created with a LINE account or e-mail address.


Step 2


Create a LINE Ads Account

A LINE Ads account allows businesses to create and manage advertising campaigns. A separate account must be created for each business.


Step 3


Register payment information

A Japanese credit card is the only acceptable payment method available for LINE Ads accounts. Account verification will be conducted based on the information provided in steps 2 and 3.

Step 2 – creating the LINE Ads account- is particularly tricky. There is quite a lot of information that has to be provided, such as basic information about the business, advertiser details, product details, billing information, etc. In many cases, ads accounts fail the review process due to insufficient information provided during this step.


The 6 most common reasons why applications fail the LINE Ads account review process

In order to ensure a smooth and successful account review, it is crucial to pay close attention to the following reasons for rejection.

Rejection based on advertiser-related information:

  1. Incorrect legal company name
  2. Unclear relationship between the advertiser and promoted website
  3. Insufficient details

Rejection based on product-related information:

  1. Incomplete product name
  2. Invalid product URL
  3. Inadequate LINE ID set up
