Know more about an unknown number before you answer. Caller ID helps identify incoming calls, block spam and unwanted callers, search phone numbers, and manage calls from one place. Available names, photos and other caller details are shown when matching information is found.

Use Caller ID as a caller identification app, spam call blocker, phone dialer, SMS app, number lookup tool and personalised caller screen.

CALLER ID FOR UNKNOWN CALLS
See available caller names, photos and details when an unknown number calls. Get more context before you decide to answer, ignore or block the call.

SPAM CALL BLOCKER
Block spam, scam, robocall, telemarketing and other unwanted numbers. Add individual callers to your block list and manage blocked numbers whenever you need.

PHONE DIALER
Set Caller ID as your default Phone app to make and manage calls in one place. Use the T9 dialer to find contacts quickly, call a number, review recent calls and return missed calls.

SMART CALL LOG
View incoming, outgoing and missed calls in an organised call history. When information is available, caller names and photos are shown beside unknown numbers.

SMS SENDER IDENTIFICATION
Identify available information for unknown SMS senders and block unwanted message senders. Organise, send and manage text messages when Caller ID is selected as your default SMS app.

PHONE NUMBER LOOKUP
Search an unknown phone number to check available caller information before calling back. Search results depend on information available in the caller database.

OFFLINE CALLER IDENTIFICATION
Identify supported unknown numbers without an active internet connection by downloading an offline caller database where available. Offline database coverage varies by country or region and can be updated when you are online.

COLOR CALLER SCREEN
Personalize incoming calls with colorful full-screen caller themes, including available live, neon and regional designs. Optional flash alerts can make incoming calls easier to notice on supported devices.

CONTACTS AND CALL HISTORY
Access contacts, recent calls, missed calls and blocked numbers from a simple interface. Single-SIM and dual-SIM phones are supported, subject to device compatibility.

PERMISSIONS AND DEFAULT APP ROLES
Some features require access to phone, contacts, call log, SMS or display-over-other-app functions. Phone and call log management features require Caller ID to be set as the default Phone app where required by Android. SMS management features require the default SMS app role. You can change default apps and permissions in your device settings.

Caller ID does not make your phone book public or searchable. Please review the privacy policy on the store listing for details about how data is handled.

Feature availability and caller information may vary by device, Android version, country and database coverage.
