How to Identify Unknown Callers on Your iPhone

Receiving calls from unknown numbers can be frustrating and potentially risky. Fortunately, your iPhone offers several features to help you identify these callers.

What Built-in Features Does My iPhone Offer to Identify Unknown Callers?

Apple provides several built-in features to help you manage and identify unknown callers:

  • Call Screening: Introduced in iOS 26, this feature prompts unknown callers to state their name and reason for calling before your phone rings. Their response is transcribed and displayed on your screen, allowing you to decide whether to answer. (techradar.com)

  • Silence Unknown Callers: This option sends calls from numbers not in your contacts, Mail, or Messages straight to voicemail. To enable it:

  1. Go to Settings > Phone.
  2. Toggle on Silence Unknown Callers.

  1. Go to Settings > Phone > Call Blocking & Identification.
  2. Toggle on the desired app.

How Can I Use Third-Party Apps to Identify Unknown Callers?

Third-party apps can provide additional caller identification and blocking features:
