Difference Between No Caller ID and Unknown Caller on iPhone

Have you ever received a call where it shows an unknown caller id or no id at all? If yes, then you might be curious what is the difference between these two and whether you should even answer the call or not.

This article will explain what each of them means and how to handle Unknown callers.

What is the Difference Between Unknown and No Caller ID iPhone

If you see “No Caller ID” when receiving a call on your iPhone, this means that the person who is calling you has chosen to withhold their information from being displayed on your phone. 

This isn’t a bad thing because sometimes people have valid reasons for not wanting their caller ID to be shown. However, it can also be used by scammers and other unsavory types to hide their identities.

On the other hand, an Unknown Caller means that your sim carrier does not recognize the phone number of the person trying to call you. 

This could be because the number is new, or it can be a landline number. It could also be a spoofed number, which is a number that has been deliberately altered to look like a credible source.

Unknown callers can also be legitimate; however, you should exercise caution if you don’t recognize the number.

If you see “No Caller ID” or “Unknown Caller” on your iPhone, it is best to use caution before answering the call. If you don’t recognize the number, it is best to let it go to voicemail.

You can check the number later to see if it is someone you know, or you can look up the number online to see if there are any associated red flags.

Should You Answer Unknown Calls?

There’s no right or wrong answer to this question – it depends entirely on your preference. Some people feel more comfortable answering calls from unknown numbers, while others prefer to let them go to voicemail.

If you decide to answer calls from unknown numbers, be aware that you could open yourself up to telemarketers, scams, or other unwanted calls. It’s always a good idea to be cautious when answering calls from numbers you don’t recognize.

If you’d rather not answer calls from unknown numbers, you can usually block them on your phone. This way, you won’t have to worry about accidentally answering a call you don’t want to receive.

How to Turn Off Caller ID on iPhone

If you don’t want to show your caller id to others, you can turn it off on your iPhone by following these simple steps:

  1. Open the Settings app on your iPhone.
  2. Tap phone and click on “Show My Caller ID.”
  3. Next, toggle off the switch next to Show My Caller ID.

When you turn off the caller id, your phone number will be withheld when you make calls. This means that the person you’re calling will not be able to see your phone number, and they will instead see “Unknown Caller.”

Does No Caller ID Mean You Have Them in Your Contacts?

No, having “No Caller ID” does not mean that the person is in your contacts. It simply means that the caller has chosen to withhold their information from being displayed on your phone.

Can You Call Back an Unknown Number on Your iPhone?

Yes, you can call back an unknown number on your iPhone. However, if the number is associated with a scam or other unsavory activity, you may want to use caution before calling back.

You can also try looking up the number online to see if there are any red flags associated with it.


So, in conclusion, an unknown caller and no caller id are two different things. Unknown caller means that the phone number is not recognized by your sim carrier, while no caller id means that the person who is calling you has chosen to withhold their information from being displayed.

Both can also be from legitimate sources, but you should use caution if you don’t recognize the number.
