Kaspersky Who Calls

Identify spam and scam calls immediately

Our verification technologies and large database of phone numbers protect you from scam calls by helping you make informed decisions quickly. Plus, any repeated scam callers are automatically blocked.

Know exactly who’s calling you

Automatic Caller ID means the app displays everything you’d want to know about an incoming call, from the name of the organization calling to its category and level of trustworthiness.

Filter out scam calls on WhatsApp

Who Calls detects spam on WhatsApp too. Filter incoming calls, identify callers like banks or research firms, block spam, and add suspicious WhatsApp callers to our database to protect others.

Block all spam calls or just specific numbers

Your phone, your rules. This premium feature lets you block numbers by category – like ‘all spam’ or ‘withheld numbers’. You can also submit spam numbers to our database, helping us improve Who Calls.
