Spam calls continue to disrupt trust and safety in mobile networks, driven largely by number rotation—a tactic where bad actors switch numbers to evade detection. This practice compromises traditional spam detection systems and affects the call experience for millions of subscribers.
Hiya’s Enterprise Caller Scoring, part of our Adaptive AI spam protection system, is revolutionizing the way we tackle this problem. Similar to how credit agencies evaluate a consumer’s creditworthiness across multiple financial accounts, Enterprise Caller Scoring connects all numbers used by a business so a caller’s reputation follows them across numbers.
The result? Businesses with positive calling practices are recognized for their trustworthy behaviors across all their numbers, even brand new ones. And callers that rotate numbers to avoid spam labels are detected and flagged even when they change numbers. In short: It’s good for good actors, while detecting the bad actors even more effectively.
We’re excited to share that through a network of expanded partnerships, Enterprise Caller Scoring now covers more than 280 million enterprise numbers in the US — a near-doubling of coverage since it first launched in early 2023.
The impact? Across 280M+ phone numbers, Hiya can quickly identify spammers who rotate to a brand new number and trustworthy actors using a phone number for the first time, leading to better spam protection without stopping wanted calls.
How It Works
Enterprise Caller Scoring is a component of Hiya’s Adaptive AI spam protection system and is one of the many protections Hiya has in place to defend against number rotation. Adaptive AI doesn’t just look at the phone number making a call — it evaluates every component of a call, including the calling behavior of the enterprise behind it. By leveraging data from Hiya’s Adaptive AI and an expanded partner ecosystem, the solution dynamically assesses risk across all numbers used by a business, encouraging disciplined calling practices.
Hiya launched Enterprise Caller Scoring in early 2023 with significant reach across US enterprise calling numbers. Since then, its coverage has only continued to expand — detecting even more number rotation, helping a greater number of positive callers connect with their customers, and contributing to a more trustworthy consumer experience overall.
Why It Matters
Unlike traditional spam analytics solutions, which treat numbers individually and are vulnerable to manipulation, Hiya takes a holistic approach. Our method offers tangible benefits for everyone (except spammers!):
- Carriers: Maintain network integrity and deliver a superior call experience.
- Consumers: Enjoy fewer nuisance calls and greater trust in phone communication.
- Enterprises: Build a consistent and reliable reputation.
