How to block an area code on an iPhone

Tried that, wasn't seeing any "Block this Caller" option under the contact. Forced closed Contacts and re-checked the contact, still not there. Checked other contacts, and it was under any of those either, even though I remember seeing it before.

Try swiping down further.

Went to Settings > Phone > Blocked Contacts, and I have a fairly long list of blocked contacts that I've collected over more than a decade, so I deleted a bunch that hopefully won't still be trying to spam me, and then went back to Contacts, and lo! Now the "Block this Caller" appeared for that area code's entry.

Apparently the Blocked Contacts list only allows a limited number of entries, ~36?

No, there doesn't appear to be a limit. I stopped counting mine and 60 and there were a lot left.

Unfortunately you will have to either do this through carrier settings, or through a filter app that you could personalize to something like “only in my contacts list”. There are several third party options that would work as well as the default iOS filtering if you look under the Settings>Phone>Silence Unknown Callers as well as Text filtering under Message Settings, AND your carrier can possibly give you the option to block incoming SMS/DATA/Calls from specific parameters in numbers.

Personally I believe a third party service would be most user friendly for what you’re trying to do. MWBS for iOS is one I’ve used. This is more so for the message filtering aspect, as calls can be whitelisted by being in your contacts or not. (Not sure messaging works the same).

I recommend the Support app for guides on what these settings do.

good luck!

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.

I am having a big problem with spam callers from one particular area code. I keep searching for a solution online and this is the one I am finding, but it does not work whatsoever. I’m doing everything right, but it just doesn’t do anything. it seems you can only block individual numbers.

The 3rd party app Number Shield will do what you want. It works completely consistently.

Perhaps this technique worked for older versions of iOS, but there is no longer a "Block" button in the contacts page.

You can still block people through Contacts. If you don't see the option, scroll down further. It's there.

What you can't do (and have never been able to do) is block all calls from a specific area code.

I also tried this, and it does not work. I have an iPhone 14 Pro with iOS 18.1.1. Created and blocked the contact per the post and I'm still getting multiple daily calls from the blocked area code.

Apple cannot do this. Ask your phone service provider.

They can certainly do this, but whether or not they will will be open to question.

As noted earlier, this does not work. Is there a third-party app that will block an entire area code?

I believe some of the third-party apps will do this. Search for "call block" or similar in the App Store.

Sending it to voicemail and not "ringing" is not blocking in my opinion.

That's precisely what it means on iPhone. Apple cannot block calls at the switch level. Only your carrier can do that. If you want the call blocked so that it never gets to the phone, you'll need to explore your carrier's options. My carrier, the last time I checked, lets me block 5 numbers for free, but the block expires after some period of time (90 days? Don't really remember). For a fee, I could get more books that lasted longer.

Note that the voicemail of a blocked caller is routed directly to the Deleted folder. You could see it if you wanted to, but you're not notified. Blocked calls also do not appear in Recents.

I will give it a look, thanks for the reply.

Try Number shield only cost 2.99 works great

I worked on this for a long time. The best solution I could find was the app number shield. I’ve tried all the iPhone settings and none work.

You have to go to your settings page after making a contact ‘1-(area code to block) and saving it.

open the phone app and scroll down to ‘Blocked Contacts’ then scroll down to ‘Add New’. Add the name of your area code that you saved in contacts. Some people say that you can just put the area code in here but I did it the way I described.

go back to the contact and scroll down and you will see in green it says Unblock Caller’. It worked. Or I hope it did. I made a Blocked Caller 1 and a BC 2 for two different area codes.

Have you tested this? Does it work?

It does not work for me either. iPhone 12 mini running iOS 17.6.1. I am able to add a contact named "Political Spam", with a phone number +1(202), which is where most seem to be coming from. I can see that caller in my blocked list. Yet, I continue to receive spam messages from that area code. I can reply "Stop", but they come back with a new list name. I can hit "delete and report spam" but then they come back with a different number. No way out, it seems.
