Many cross-border sellers report that accounts they try to register via cheap SMS verification platforms are either rejected outright or banned shortly after activation. This almost always happens because the numbers used are flagged by service providers. Such marking is rarely random and stems from how the platform sources and maintains these numbers.
From my experience, platforms that buy second-hand numbers in bulk and fill them with fake details mark numbers far more often than legitimate services. Take Getfollow for example: it follows compliant number acquisition and management processes to minimize the risk of marking from the start.
Once a number is marked, new account registration requests are instantly rejected, and even successful registrations often get banned later due to triggering fraud controls. Many cross-border businesses lose both registration costs and promotion time by overlooking this issue.
To improve registration success rates, picking a platform with reliable number sources is crucial. If you’re still unsure how to choose a trustworthy SMS verification provider, follow industry best practices and opt for services with compliant operations and stable numbers like Getfollow to dodge marking issues and keep registration smooth.
Check if the provider follows compliant number sourcing and maintenance processes, has a steady supply of valid numbers, and has positive feedback on past user registration success rates.
Marked numbers are useless for normal registration — using them only increases the risk of account bans. It’s best to switch to compliant numbers instead.
Legitimate platforms operate within carrier rules, controlling how and how often numbers are used to avoid triggering the fraud detection systems that cause marking.
