When entering overseas markets where LINE usage is high, companies often already have a batch of mobile phone numbers, but cannot confirm how many of them actually use LINE. If put into operation directly, the number of numbers cannot be converted into the actual reachable customer scale.
There are many original numbers, but the proportion of LINE users cannot be confirmed in advance.
The sources of numbers in different markets are complex and the degree of data availability varies greatly.
Sales staff need to repeatedly save contacts and manually find LINE accounts
Unregistered LINE numbers occupy import, grouping and customer service follow-up resources.
It is difficult for companies to reasonably arrange marketing budgets based on channel coverage
