How do I see all the numbers I’ve blocked on my iPhone?

Couple extra angles to check that @suenodelbosque didn’t hit directly:

  1. Quick “am I blocked or just filtered” test
    Grab someone you think you might’ve blocked and have them:

    • Call you
    • Text you
      Blocked: calls go straight to voicemail, and texts never show up at all.
      Filtered: calls might still ring silently or go to voicemail, texts might land under “Unknown Senders” in Messages.
  2. Check if you accidentally blocked via recent calls
    A lot of “whoops I blocked them” happens from the Recents list in Phone:

    • Open Phone → Recents
    • Look for the little circled “i” on the right
    • Tap that on people you’re suspicious about
    • Scroll down and see if it says “Unblock this Caller”
      If it says “Unblock,” they’re in your blocked list even if you forgot doing it.
  3. Cross check contact cards
    If you blocked someone from their contact card, it can be easier to spot from there than from the global list:

    • Open Contacts
    • Pick the person you’re missing calls/texts from
    • Scroll down
    • If you see “Unblock this Caller,” they’re blocked for all numbers on that card (including email for FaceTime/iMessage).
  4. Multiple numbers for one person
    iOS treats each phone/email entry separately, but the Contacts UI can be confusing:

    • If a person has 2 phone numbers and you only blocked one from Recents, only that specific number is blocked.
    • In the blocked list, you might only see one number, while you’re expecting their whole name, so it’s easy to miss.
  5. iMessage vs regular SMS weirdness
    If the person uses iMessage and SMS:

    • Blocking hits both, but if they recently changed numbers or turned off iMessage, that new number might not be blocked, even if the old one is.
    • Check both their old and new entries in your Recents / Messages threads.

So yeah, use the Blocked Contacts list like @suenodelbosque described, but also manually open the specific contact cards and Recents entries for the people you’re missing. Half the time the “mystery” is a single number on a contact being blocked while the rest looks fine.
