When operating WhatsApp business in the Vietnamese market, the need to register accounts in batches is very common, but many teams will encounter problems such as high registration failure rates, restricted numbers, or device association. We once helped a cross-border e-commerce client set up a localized operations team in Ho Chi Minh City. On the first day, they lost 30 new accounts due to improper IP switching. Do you encounter this problem? According to the DataReportal 2025 report, the number of WhatsApp users in Vietnam has exceeded 76 million, but official supervision of batch registration is becoming increasingly strict. This is a typical operational search requirement.
