How to Tell Who Called You Without Caller Id

We've all been there – you know you have the right number, but your calls never get answered and your texts are ignored. It's possible that they could be busy, their phone could be dead, they could be on vacation, have no signal, or something else. Just because you can't reach someone doesn't necessarily mean they have blocked you.

Is there a way that you can tell if someone blocked your number? Unfortunately, there are no directly specific warnings or messages to tell you the person has blocked your number. However, with some detective work, it's possible to figure out if someone has blocked your number, preventing your calls or texts from reaching them.

How Does Call Blocking Work?

When you use call blocking, there is a specific process that is initiated. Your phone, landline, or cell informs the network that calls from a specific number are to be blocked. On a landline, this block is performed at the closest telephone exchange to your property. So the caller will make their call, it will traverse the network, get to the exchange that will deliver the call to your property, and be stopped there.

On a cellphone, the block is placed on the handset. The call transits the network and is delivered to your phone but the phone doesn't answer it. The caller is transferred directly to voicemail. This is all done behind the scenes so you as the user will not be aware that a call was connected and refused. Because the call is transferred to voicemail, it's difficult to tell you've been blocked. There are no direct indications that indicate you've been blocked.

Has someone blocked your number?

Just because someone doesn't answer your call, does not mean they have blocked you. If you suspect they have blocked your number, there are a few things you can do to try to find out. These methods are far from perfect but there's not really a way to get a definitive answer.

Call From a Different Number

Cell phone call blocking is done based on the source number. The Operating System (e.g., iOS) recognizes the calling number, checks the block list, and will either allow or block according to whether it finds your number on the block list. The simplest way to find out whether someone blocked your number is to use a different number.

Because a blocked call and a disconnected phone number often act similarly, this is the most effective way to figure out if someone blocked your phone number.

Of course, not everyone has a second phone lying around. Another option for you is to use a free Google Voice number.

If the person you're trying to reach has blocked you, the Google Voice number will be able to get through. However, if the person's phone is dead or disconnected neither number will be able to get through.

Withhold your number

If you type *67 on your US phone the number is blocked from caller ID. The number transits across the network as usual but at the final cell tower, it is held back. This allows billing but stops your number from being presented to the called party.

As the block is on the cellphone itself and not the network, it will be delivered as normal. You can try to test whether your phone number has been blocked by withholding your number from the caller id system.

There are call blocking apps that can work around this but for an OS block (i.e. the call blocking app that is set up using Android or iPhone iOS) the call should be delivered as usual. Some people automatically ignore withheld or private numbers so bear that in mind when using this approach.

Send a Text Message

If you're an Apple user you can find out whether your number is blocked by sending a message. Send an SMS to the person and watch the notifications. If that someone blocked your number the SMS will never change the status of the message to "Read."

If it stays in Delivered status, it is possible that they blocked your number. Keep in mind, some newer versions of Android also offer read receipts from other Android devices.

Confirm the Block

Odds are at this point you've figured out that you have or have not been blocked by the recipient of your phone calls. If your friend answers another phone number or that phone number doesn't get the same message as yours, you've been blocked.

Of course, if you're trying to make amends you could always contact the other person on a social media site or something similar, but this isn't always a good idea.

Frequently Asked Questions

If I dial *67 can I still get through if I'm blocked?

Based on our tests in April of 2021 this still works. If you dial *67 then the recipients full ten digit phone number, your call will ring through. The recipient's caller ID will say 'Unknown Caller' or something similar.

These days, this probably isn't the best way to get the other person to answer, but you can tell by how the phone responds whether you've been blocked or not. If the feedback tone responds the same way as it did when you called from your number, the person is likely out of range of cellular service or having another issue.

However, if it rings just like normal, you've probably been blocked.

How do I know if someone blocked my texts?

It's a little more difficult to tell whether someone blocked your text messages. Assuming we're using the native messaging app with their phone number it won't be too difficult though. When someone blocks your phone number, they're blocking you from text and calling.

This means that you can use any one of the methods we've listed above to know if someone has blocked your phone number from texts.
