Important limits
Caller ID can be spoofed, so a high risk rating means people have reported suspicious activity involving this displayed number. It does not prove that the registered owner of the number made the call or text. Community reports describe individual experiences and are not official confirmation of a scam. How caller ID spoofing works.

Safety score
2 reportsHow this score was worked out
Each report rates the number as safe, unknown, suspicious or spam. The score combines those ratings, giving more weight to clear scams, and each person counts once. A number only reaches high risk once several people have independently reported it. Scores of 70% and above count as high risk, 40% to 69% as medium, and below 40% as low; a low-risk number reads Maybe Safe once someone reports it as safe. More about spam scores
Why this number is rated Medium Risk
This number is rated Medium Risk because community reports are mixed: 1 of 2 describe spam or suspicious activity, while 1 describe a legitimate or unknown call.
Ratings reflect screened community reports, not official records. How the spam score works.
Confidence: Medium
Based on 2 community reports. Confidence describes how much report evidence sits behind this page, and is separate from the spam score.
