How to Block Spam Calls on iPhone
Block a caller or silence unknown callers using current Apple guidance.
Published 2026-09-28 · Reviewed 2026-09-28
On current iPhone software, you can block a specific caller from the Phone app or choose how calls from unsaved numbers are handled. Menu names vary by iOS version, so check the current Apple instructions if your screen looks different.
Block one caller
Open the Phone app, find the call or contact, open its details, and choose the block option. On some versions Apple lists Block Caller near the bottom of the contact card.
Silence unknown callers
In Settings, open Apps → Phone and review the call screening or silence choices. Silencing unknown callers can also hide useful calls from people you have not saved, so review voicemail and filtered calls when expecting a service or delivery.
Blocking a displayed number may not stop a scammer who changes or spoofs caller ID. See what spoofing means.
