Spam Protection

Continuously Updated Spam Protection

Spammers frequently change numbers to avoid being blocked. Sync.me continuously updates its spam detection lists using reports from millions of users and advanced detection technology to quickly identify new spam and fraud calls.

Spam Protection Built on 5 Billion Numbers and Real User Reports

Sync.me has been blocking spam calls since 2011. The protection works because it's built on two things that static blocklists can't replicate: a global database of over 5 billion phone numbers and a live community of more than 20 million users reporting spam in real time. When a new scam campaign launches or a spam number switches to avoid detection, community reports from users worldwide feed back into the system, often within hours. That's what keeps the spam call blocker accurate against numbers that have never been flagged before, not just the ones that have been circulating for months. Scale provides the foundation. The community keeps it current.
