Where our data comes from.
Every finding on Signal Sanctuary is labeled by its source. Here's how we verify caller identity, evaluate robocall scores, and keep the community-reporting model accurate.
Carrier registries (NEUSTAR/ICONN), FCC and FTC enforcement records, court filings, and primary statutory text. Carries the highest confidence and is labeled Verified wherever it appears.
AI-generated assessments from public internet context — scam likelihood, likely company, risk levels. Always labeled AI assessment and given a confidence rating. Estimates, never asserted as fact.
Allegations submitted by users like you. Labeled Community and shown as reported claims, not verified facts. Volume and agreement between reports raise — but don't confirm — a number's reputation.
Each day we scan the web for new, publicly accessible research sites and databases for phone-number and company research, and add them here. These are third-party public sources — not AntiSpamLogic data — and are linked for your own verification.

Accuracy safeguards
Each data point is tagged Verified, Algorithm, or Community so you always know how much weight to give it.
AI output uses reported-as language, never names an individual or business as a scammer without public backing, and flags low-confidence estimates.
User reports are never treated as verified evidence. They inform the picture but never stand alone as fact.
Your evidence locker and blocked-number list are private to your account under row-level security. We never sell your data.
Because Caller ID can be faked, we warn when a displayed number may not be the true origin — never assume the registered owner placed the call.
