If you're blocked by someone, your calls will go straight to voicemail, and your voicemail messages will head to the 'blocked' section immediately. The other person won't receive your calls, won't be notified you called, and won't see a badge for your voicemail.
Avoid unwanted calls on iPhone
When you block a number, you no longer receive calls or text messages from that person. This step helps stop unwanted spam calls, but it's also great for personal reasons. The first indication that something's up is the most obvious: You call and send text messages, but you get no response.
You can delete the person's number from your contacts and see again whether the number reappears as a suggested contact or not. If the number appears, which means you are not blocked. Launch the dialer app and go to the Contacts tab on your Android phone. Tap on the contact person you doubt that he has blocked you.
Send a Text Message If that someone blocked your number, the status will never change to “Read.” If it stays in Delivered status, they may have blocked your number. Keep in mind, some newer versions of Android also offer read receipts from other Android devices.
6 Ways to Check If Someone Blocked Your Number on iPhone
So, give this nifty tip a try to get the mystery out of the way.
Open the Phone app. Choose Contacts. Select the contact. View the phone number.
Caller ID
This means that people you add on these services can call you and text you. Worse, they can even use your phone number to figure out your real name and address through a form of Internet stalking known as doxxing.
A red flag that you've been blocked is when you don't see the delivery status or the read receipt at all. The message you just sent will still be in a blue bubble, but it will have no delivery status below it – not even a "Not Delivered."
How to find someone's name using their phone number for free
If the call ends after one ring (or, in some cases, half of a ring) and you are diverted to voicemail, you are either blocked or your contact's phone is dead. If the phone immediately hangs up or beeps rapidly, then either the line is busy or the contact blocked you through their carrier.
Use the *67 code Specifically, adding *67 to the start of any phone number will block your caller ID when you call that number. This is a quick and temporary way to block your number when making calls. Nearly all phone service providers support it, it works on both smartphones and landlines, and it's totally free.
The person you've blocked will never get any sort of official notification. Google respects your privacy and will not let the person know that they've been blocked.
