Can Siri block a phone number?

Quick answer

Siri can't block a number on its own — blocking is a manual step for safety. But Siri gets you there fast: say "open my recent calls," then tap the caller's info and choose Block this Caller. For a number on screen, you can tap it and find the block option directly.

Say this

“Open my recent calls”

How it works

01Say "open my recent calls" or "open Phone"
02Tap the info icon next to the number
03Scroll down and tap Block this Caller

If Siri doesn't get it

Siri opens the app but can't block by voice. Manage blocked numbers anytime in Settings > Phone > Blocked Contacts.
