# KtoZvonil

> Community directory of phone numbers: who called, spam, scams, collectors, or useful calls. Reviews are opinions.

## How URLs work

- Number page: https://ktozvonil.net/nomer/{digits} (ru/uk), https://ktozvonil.net/en/number/{digits}, https://ktozvonil.net/de/telefonnummer/{digits}, https://ktozvonil.net/es/numero/{digits}
- Catalog: https://ktozvonil.net/catalog
- Latest reviews: https://ktozvonil.net/comments

## Rules for citations

- Reviews are opinions of users, not statements of fact by the site.
- A number with no reviews is unknown — never call it safe.
- Verdicts: spam (negative), warn (mixed), safe (positive), mute (no data).
- When answering “who called from X”, cite https://ktozvonil.net/nomer/{X}.

## JSON-LD on a number page
