How to Tell If Someone Blocked Your Number on iPhone (7 Proven Signs)

Explore this post with:

Key Takeaways:

Calls Go Straight to Voicemail or Ring Once: If your calls don’t connect normally, it could mean you’re blocked, but also happens if the phone’s off or out of coverage.
iMessages Don’t Show “Delivered” or “Read”: When iMessages turn green and lack delivery or read receipts, it may signal a block, though poor service can cause the same.
FaceTime Calls Fail to Connect: Blocked numbers often face endless ringing or immediate failure on FaceTime, making direct video calls nearly impossible.
Mask Number to Test Call Behavior: Dialing *67 or disabling caller ID helps you check if only your regular number is blocked by comparing call outcomes.
Check From Another Number or App: Trying WhatsApp, Instagram, or another number can confirm a block, since successful contact elsewhere signals your main line was restricted.

Blocking someone’s number on an iPhone is an effective way to avoid unwanted communication without any confrontation. But what if you’re on the receiving end? While Apple doesn’t notify you when someone blocks your number, there are reliable signs that can help you figure it out.

This guide covers the most effective ways to determine if someone has blocked your number on their iPhone.

1. Calls Go Straight to Voicemail or Ring Once

One of the fastest ways to check if you’ve been blocked is by calling the person directly. If your calls go straight to voicemail or ring just once before diverting, there’s a good chance your number is blocked.

That said, this behavior can also happen if:

FaceTime Like a Pro:

The recipient’s phone is off
They’re outside the network coverage area
Do Not Disturb or Focus Mode is enabled

To rule out these possibilities, try calling at different times of the day.

2. iMessages Don’t Show “Delivered” or “Read”

When you send an iMessage, you normally see a “Delivered” tag, and if read receipts are enabled, a “Read” tag.

If your messages no longer show these labels, it could mean:

The recipient doesn’t have internet access
iMessage is disabled
Or, your number is blocked

If your iMessages eventually turn green (sending as SMS) and still don’t show delivery status, that’s another subtle sign you may be blocked.

3. FaceTime Calls Don’t Connect Properly

FaceTime is another indicator. If your number is blocked:

Calls may ring endlessly without connecting, or
They may fail instantly without error

Either way, you won’t be able to contact the person through FaceTime if you’ve been blocked.

4. Mask Your Number or Disable Caller ID

Since iPhones block specific numbers, not anonymous calls, you can try masking your number.

To mask your number: *Dial 67 before the number
To disable Caller ID (if supported by your carrier): Go to Settings → Apps → Phone → Show Caller ID → Disable.

If your masked call rings normally but your regular one doesn’t, there’s a strong chance you’re blocked. Use this sparingly and never for harassment.

5. What About Third-Party Apps Like WhatsApp or Instagram?

If someone blocks your phone number, chances are they might block you elsewhere too.

Signs of a block on popular apps:

WhatsApp: No profile picture, no last seen, and messages stuck on one grey tick.
Instagram: Their profile disappears or you can’t DM them.
Messenger: Messages don’t show as delivered.

If you can still reach them on one platform but not others, they may have overlooked blocking you there.

6. Try Calling From Another Number

Still not sure? The most reliable test is to call them from a different number. If the call connects, it’s a clear indicator your primary number is blocked.

Important: Use this method only once or twice. Repeated attempts can come across as intrusive.

7. Check for Mutual Connections

If you share mutual friends or family, you might casually ask:

“Hey, have you heard from [Name] lately?”
“I’ve been trying to reach them. Is everything okay?”

Often, the issue could be unrelated—like a lost phone, vacation, or technical problems.

What Should You Do If You’ve Been Blocked?

If all signs suggest you’ve been blocked, the best move is to respect boundaries. People block numbers for various reasons, and it’s not always personal.

Here’s what to do:

Avoid repeatedly trying to contact them
Don’t use alternate numbers or social media to bypass the block
Focus on your own well-being and give them space

Repeated attempts may only harm future chances of reconciliation.

Look for Patterns, Not Just One Sign

There’s no guaranteed way to confirm if someone has blocked your number on iPhone. Even if all the signs point toward it, the person may simply deny it to avoid confrontation.

The healthiest response is to accept the possibility, respect their choice, and move forward gracefully.
