Quién te llamó? is a Spanish-language community website that helps people identify unfamiliar or missed phone calls. Visitors can search for a number to see information and reports shared by other users, and can browse the latest comments about calls received in Spain. These reports describe suspected spam, telemarketing, automated calls, silent calls, and possible scams, as well as legitimate businesses and services.

The site also publishes guidance on common telephone fraud, including calls that prompt costly callbacks, fake prize or holiday offers, and callers impersonating banks. Its safety advice encourages users not to disclose personal or financial information unless they have verified the caller’s identity, and to hang up when in doubt. By combining a searchable phone-number directory, recent user feedback, and practical scam awareness information, the website offers a public resource for assessing unknown calls and learning about reported calling patterns.

The information is community-submitted, so individual reports reflect users’ experiences rather than guaranteed verification of a caller’s identity
