How does LINE number registration detection determine whether a user has subscribed to LINE?
In markets such as Japan, Taiwan, and Thailand, LINE is the mainstream tool for daily communication. For those who do local promotion, social traffic or customer development, the most practical question is not "how to add friends", but whether the numbers on the list have LINE activated. If the data source itself is inaccurate, no matter how many subsequent promotion actions are taken, it will only consume resources.
