BAND is a national-level community tool under South Korea's NAVER. It covers a large number of users in local group buying, maternal and infant, beauty, local life, and foreign trade wholesale. Merchant bulk mobile phone number expansion without pre-registration screening will result in multiple losses in conversion, risk control, cost, and compliance:
The number pool is mixed with a large number of invalid numbers, and social invitations and private message promotions are completely ineffective.
Frequent batch operations on unregistered numbers can easily trigger the platform’s anti-spam risk control and result in batch bans on accounts.
Full-link marketing resources are severely wasted, and the launch-to-production ratio continues to decline.
Manually verifying the registration status one by one, the cleaning efficiency of massive numbers is extremely low
Indiscriminate mass messaging can easily lead to user complaints and violate Korean personal information protection regulations.
