How it works.

An unknown number calls. The person who received it searches that number here and, if they want to help, describes what happened: the kind of call, roughly when, whether they answered, and what took place.

Phone numbers get written in many ways. Before anything is stored, the number is converted to a single international form, so 081-234-5678, +66 81 234 5678 and 66812345678 all reach the same page rather than splitting one number's history across three.

The report is not visible to anyone yet. A moderator reads it and decides whether it meets our standards — no personal information, no abuse, not a duplicate, and an actual description of what happened.

Only after approval does a report appear on the public page or affect the number's risk score.

The approved report joins the number's history. Its category feeds the breakdown, its date sets the “last reported” time, and its weight is added to the risk score.

The next person who searches that number sees it. That is the whole mechanism — the scoring is fully published, and there is nothing else behind it.

CallsAlert currently holds 1 approved reports across 1 numbers.

The database is young and grows only when people contribute. If you search a number and find nothing, yours can be the first report on it.
