About CallsAlert.

CallsAlert is a free public service for checking unknown phone numbers. When someone receives an unwanted call, they can describe what happened. Everyone else can search that number and read what previous callers experienced.

There is no account, no subscription and no charge. You do not need to sign up to search a number or to submit a report.

Every piece of information on a number page comes from people who received a call from it. A report records the kind of call, roughly when it happened, whether the call was answered, and a short description of what took place.

Reports are published anonymously. We do not show a reporter's name, email address or any other identifying detail alongside their report, because we do not ask for them.

Nothing is published automatically. Every submitted report starts in a pending state and is reviewed by a moderator before it appears on a public page or counts toward a number's risk score.

Moderators reject reports that:

• contain personal information about an individual
• are abusive, threatening or defamatory
• appear to be spam, advertising or automated submissions
• are duplicates of a report already on file
• contain no usable description of what happened

Sometimes a report is worth keeping but contains something that is not. Where a submission includes a name or an address, a moderator may remove that detail rather than discard an otherwise useful report, or correct a category that was clearly chosen by mistake.

Any report edited this way is marked “Edited by a moderator” where it appears, so you always know when the wording in front of you is not exactly what was submitted. Moderators do not change the substance of what someone described, and editing can never publish a report — that is a separate decision.

A risk score is a transparent count of what the community has reported. It is not a prediction, it is not machine learning, and it is not a judgment about the person or business behind a number.

Each approved report contributes points according to the kind of call reported:

Recent reports count for more than old ones, because someone deciding whether to answer right now is better served by what happened last week than by what happened three years ago. Older reports are discounted but never discarded entirely.

Reports that a moderator rejected contribute nothing at all. The total is capped at 100 and falls into one of four bands:

• Low risk — 0 to 19
• Medium risk — 20 to 49
• High risk — 50 to 74
• Very high risk — 75 to 100

A number nobody has reported shows no reports, which is a different thing from low risk. It means we have no information, not that the number is safe.

A report is a claim by a member of the public, not a finding of fact. People make mistakes, numbers get reassigned, and caller ID can be spoofed so that a call appears to come from a number its owner has never used.

CallsAlert does not accuse anyone of a crime and does not verify the identity behind a number. Please use your own judgment.

We collect as little as we can: the content of your report, and technical information needed to keep the service working and to prevent abuse. IP addresses are stored only as irreversible hashes and are never displayed.

The privacy policy sets out exactly what is collected and how long it is kept.

Search for the number, then choose “Report this number” on its page. You will be asked what kind of call it was, roughly when it happened, whether you answered, and what took place.

Please do not include passwords, account numbers, addresses or anyone else's personal details in a description.
