How to block an area code on an iPhone

A recurring question in this Community which I struggled with myself is: How do I block all calls from a specific area code?

What I finally figured out was to create a new contact in my Contact list, with nothing but:

+1 (xxx), the xxx being the problematic area code.

Then, when that contact is saved, open it, scroll to the bottom, and click on "Block this Caller", which is in red.

Open your Blocked numbers list in Settings and verify it's there.

iPhone 11, iOS 16

Just an update for Feb 2025


tl;dr this does not work. But here are some more details in case anyone is curious.


  • Yes there is a "block caller" option in the current version of iOS.
  • You may have to scroll to the bottom of the contact to see it...
  • Adding as an example +1 (901) as a contact number and blocking it will not prevent calls from the 901 area code.
  • In my experience 3rd party spam blockers don't work consistently, I would definitely not pay for one.
  • The only thing that kind of works is "Silence Unknown Callers" but you're still going to get notifications if you have them enabled. There is no way to make them never reach your phone that I have found, even with a paid application.


I hope this helps some of you out. Spam has been a problem for decades and there never has been, nor do I anticipate a solution as the problem makes too much money for those that would be required to fix it.

Dear Apple (Bug Report):
This seems like a bug. I'm on an IPhone 13 Mini running 18.3.1. When handling blocked calls, it should be enough to have a single contact entry registered in the phone app's "Blocked Contacts" list and have every associated number for that contact be blocked. Currently, it seems that each associated number for the same contact must have its own entry in the "Blocked Contacts" list - which defies user expectations and is leading to a ton of confusion around a feature that would otherwise be an incredible tool in the fight against SPAM.

I'd also imagine that this bug is affecting people who block a contact and then add a new (or edit an existing) phone number to the contact. The new information doesn't get registered to the blocked contacts list even though the contact appears blocked from the contacts page.

Post election (I thought they would go away) calls for money out of the area code where I used to live. Blocking them one by one doesn’t work as it seems they have bought a block of numbers and the message just rolls over too a new line and I probably get 30 calls a day via message not email. How to get them out of my life??

They don’t need to buy a block of numbers. They can make up any number they want to, even if it is in use by someone (isn’t modern technology wonderful?) That’s why you will frequently see a caller ID that doesn’t have anything to do with the scammer calling you. A common trick is to send a caller ID with the same area code as yours, so you are more likely to answer it.
