Puhelinluettelo
Puhelinluettelo is a Finnish term meaning "telephone directory" or "phonebook." It refers to a compiled list of telephone subscribers and, in many cases, businesses, arranged alphabetically and including contact details such as names, addresses, and phone numbers. Traditionally, puhelinluettelo described printed booklets published by telecommunications operators or directory publishers and used as a public resource to connect people and organizations.
Entries were typically organized by surname in residential sections and by business name in commercial sections.
With the rise of the internet and mobile communications, puhelinluettelo has largely shifted to digital formats.
