There are a few clear signs that indicate if someone has blocked your number on their iPhone or Android phone:
- Your calls go straight to voicemail without ringing
- Your text messages remain permanently undelivered or show only “delivered” status
- You receive an automated “User Unavailable” message when trying to call
- Your previous texts with blue message bubbles turn green (iPhone only)
- Trying to call shows your number as “No Caller ID” or “Anonymous” instead of your name
Essentially, any unexplained inability to get through to someone who previously responded or took your calls likely means they have blocked your number on their smartphone. Subtle signs in how your incoming calls or messages are displayed or rejected highlight whether their device has blocked your ability to contact them.
Is it Possible to Know if Someone Blocked your Number?
Yes, it is absolutely possible to know if someone has blocked your number on their phone. There are several clear signs that can confirm if you have been blocked by someone:
- Your calls to that person go straight to voicemail every time without ringing. However, do note that their phone being switched off or out of coverage can also result in the same, so it doesn’t always guarantee a block.
- Your text messages to them continually remain undelivered or show just a single tick/delivered status but don’t get the second tick for read.
- You receive an automated reply saying “User Unavailable” or something similar when trying to call them. This is a definite sign of being blocked.
- The color of your text/iMessage bubbles with them have changed from blue to green. This indicates they may have blocked you on their iPhone.
- Your incoming caller ID now displays as ‘Anonymous’ or ‘No Caller ID’ instead of showing your number or name to them when you call.
So while there is no outright notice, analyzing the indications around your calls and messages should reveal if that person has actually blocked your number recently or not. Just one of the symptoms may not be conclusive proof but consistent occurrence of multiple signs does imply you got blocked.
How do you Know if Someone Blocked your Number?
Here are some easy ways to know if a person has blocked you by detecting signs on an incoming call or text message:
1. The Call Goes Straight to Voicemail
If your calls are going straight to voicemail without ringing, chances are high the person blocked your number. However, it could also mean their phone is switched off or out of reach.
2. Texts/iMessages Aren’t Delivering
If the texts or iMessages you send to someone remain undelivered or show a single tick/delivered status but never get the second tick, it’s likely that you have been blocked.
3. Automated Replies
If you receive an automated “user not available” message, it’s a sign of getting blocked by an iPhone user.
4. Incoming Caller ID is Hidden
If previously the person could see your name or number when you called but now it displays “No Caller ID” or “Anonymous”, they have probably blocked you.
5. Text Bubble Color Change in iMessage
On iPhones, a green text bubble instead of a blue iMessage bubble indicates your messages are going through as SMS and not using data, hinting at a block.
How to Know If Someone Blocked You on iPhone?
It’s quite frustrating when you realize someone blocked you on iPhone without any heads up. Here are some nifty tricks to find out if someone blocked your number on their iPhone:

Method 7: Enter *67 Before Dialing the Number

If all your calls go directly to voicemail without ringing, chances are extremely high that the person has blocked you.
