A clear risk level tells you at a glance whether to be careful. WARN OTHERS IN SECONDS Got a scam call? Pick what it was, such as bank impersonation, fake delivery, investment or crypto, tech support, telemarketing, a robocall or a silent call, and add a note if you like. Your report helps the next person who gets the same call. THE MOST HELPFUL COMMENTS FIRST Vote comments up or down. The most useful ones rise to the top. SHARE STRAIGHT FROM CONTACTS Share a contact to Who is Calling and look it up in one tap. If a contact has several numbers, choose the one you want. YOUR PRIVACY • The app never asks for access to your contacts. Only the numbers you choose to share or search are looked up. • When you share a contact, only the number is saved, never the name. • No sign-up, no account. • You can remove your own reports and comments at any time. IS IT YOUR NUMBER? If people are reporting your number by mistake, tell us from the number's page.
