Kukasoitti. fi is a Finnish phone-number lookup and discussion service that helps people assess calls from unknown numbers, including mobile and landline numbers. Visitors can search for a number and read experiences shared by other users, along with information such as recent interest in the number and, where available, the location associated with a landline.

Number pages also display user assessments, which may classify calls as safe, neutral, disturbing, or dangerous. The site features lists of frequently searched and discussed numbers, recently added or searched numbers, and numbers reported as disturbing or dangerous. Its partially moderated forum allows users to contribute information about calls, with particular attention given to suspicious or reported comments.

Kukasoitti. fi also provides frequently asked questions explaining its number-view statistics and how the service works. For users who want a mobile option, the site promotes the free Call Insider application, available through Google Play.

The service is intended to help visitors make better-informed decisions about unfamiliar calls using community reports and number-search activity
