They dont do it because then how would they remind you that the polls are open or "so and so needs your help!" every election cycle or mid term

its probably about as good as the national do not call list and putting your number on that, which seems to do very little if anything.
It did at the beginning. I remember putting my number on that and then, almost suddenly, no spam calls. It was AMAZING. But it didn't last long when places realized they just... didn't have to bother even paying attention to it.

I have over 5,000 blocked contacts. Back some years ago, spammers would use a phone number that matched the first 6 digits of yours, like 201-555-xxxx. I generated a list of all numbers in that pattern (except for my number), imported them into my Contacts app on my Mac, blocked them, then deleted the contacts. I thought my phone was going to die, it didn’t like processing that massive block list.

I see that there are now only 5000+ blocked, so I’m guessing something failed when blocking that initial 10K, but most of that 5K is for the pattern matching my number.
 
We wouldn't need to block so many numbers if "block unknown callers" didn't actually make the problem worse.

The fact that you have to clear these blocked calls separately, in a separate section of the phone app, is absolutely insane. I don't even want to know that the call happened.

So the iPhone doesn't like even 5,000 contacts.

Occam's razor says Apple saw the issue in diagnostic logs, and they're moving to limit the issue.

Is there any particular reason why you didn't use silence unknown contacts?

Edited to add: silence unknown is newer, so it could be that it wasn't available at the time.
 
I'm at 547 blocked contacts, and I get 5-10 spam calls a day, and each unique number gets blocked. I got a second phone line, but all it took was one person selling that data or trading my contact information for mobile game currency to associate that number with me. So changing numbers is not a real option. It's only temporary relief until they find that number.

This is after I've turned on spam filtering at the carrier level and unknown callers on the phone itself. I have the silence option set, and I still get a notification for every single unknown caller and every single message they leave. If there is another silence setting that will get rid of the notification, then I'd love for someone to explain it. The only thing that silence does is just not ring my phone.

What's annoying is that the notification shows up on every single Apple device that I own if I have call forwarding set up. Watching a movie on Vision Pro and visionOS will happily send me notifications for messages that I blocked days ago.

The best part about the carrier blocking is that the only calls it actually blocked were the ones from my family. I had to manually allow their numbers. But the loan and toll companies got right through.

What I want is basically passcodes for phone calls. Basically, if I share my contact with someone, both parties generate a unique passcode, and both parties must use that to establish a phone call. If someone is abusing or lost control of that passcode, then either side can revoke it, and you never hear from them again until you share your contact again. Magically*, no more spam. No message from people you don't want to hear from. I shouldn't have to depend on an algorithm or the benevolence of a business to stop calling me. I should have complete control.

*magically is doing a ton of heavy lifting.

They should just make a whitelist to allow people and block everyone else for those users who just want select people to call.

The problem with silence callers is you still have to wade through messages even if they are silenced.
“Block unknown callers”? Your contact list would be your whitelist.
 
This just reinforces my belief that Apple
Software team needs fresh cleaning and wiped, hire new talent. Work for one of the top tech companies in the world and this is the best new feature you can come up with? That’s seriously embarrassing.
 
So first of all..why is there a limit? Second of all, why are people manually blocking 20k numbers?


They already have this - enable Silence Unknown Callers in settings, then only your contacts will ring. Everyone else can either go straight to voicemail, or have a little call screening flow where they have to tell Siri who they are and why they are calling.
The problem with this, sometimes doctor’s offices call from other numbers not saved in Contacts. For others, it could be job opportunities or a relative calling from a new number etc.

Yes, people can and should use voicemail if it’s important, but half the time, at least for me, the voicemail never goes through until a few days later.
 
Everyone should just register their number with the National Do Not Call Registry.

That only works (sometimes) for LEGITIMATE callers. Most of the junk is from criminal spammers.

They aren't particularly bothered by the fact that you put your number on a do not call list. 🙂

This is BS i was having a problem blocking numbers since ios 26.5 i have 500 numbers blocked, asked me to unblock a number i did. still cant block the other number saying too many blocked numbers. so the glitch persists. Apple needs to fix this issue

The most infuriating part is that two decades ago a federal law made it a FEDERAL CRIME to call someone on the national do not call list. But unlike the limitless nuisance laws for which entire divisions of heavily armed agents are eager to smash down the wrong door and shoot people the do not call list has NEVER seen any enforcement.

This really shouldn't be Apple's problem to solve. They are ill positioned to handle the task and the block list is clearly more for jilted lovers than Indian scammers.

The Carriers could make some big dents by blocking calls at the switch routing level. Just like spam emails: if your switch sends too many spam calls to our subscribers we simply severe your connection to the telephone network. Let THEIR network provider figure out how to get his legit customers (assuming there are any) reconnected to the US telephone system. THAT would be effective.

But honestly this is a LAW Enforcement problem. Not Apple's hash table problem. Although I do have just enough outrage left to say "WTF?!?! How am I supposed to delete thousands of old numbers one at a time or know how old they are when they appear to be unsorted?" That is just offensive.
 
If you need to block more than 20,000 contacts, you likely have bigger issues

This quip begs the question of whether you are living on Planet Earth. Once the crooks get hold of your number, the big issue is all about them and not you. They call from many thousands of constantly changing numbers. You simply cannot block them one at a time. It does no good at all. Entire exchanges need to be blocked all at once to get any relief.

For this, I use the Simple Call Blocker app on my phone, which in theory currently blocks 152,000 numbers. Unfortunately most of them still ring through on my Mac.

Silence unknown callers needs to be re-worked.

Before: Phone app icon badge > tap recents > see it's a spam number
Now: Phone app icon badge > tap calls > tap dropdown menu > tap unknown > see it's a spam number > tap back into calls
 
some users have been unable to block additional contacts after hitting a 20,000 limit. Other people have mentioned running into issues after 8,000, and some have experienced issues with even fewer phone numbers blocked.
Geez. If I had that much of a problem (assuming these are spam calls) I'd be getting myself a new phone number.
 
Maybe there should be a rule that if you get blocked by X number of people, you should loose your phone number.
(In the case of political spam texts especially, X should be a very small number.)

They do, just not in the U.S. So, yes, the claim is proven BS. Just make a law and it will stop at least all non-scam callers who identify themselves and care about legalities.

E.g. in the EU, unsolicted calls are not allowed with a fine up to €300k. It's not that they are not happening, but they are few and far between. I usually block them right after I got the call. Not sure if they all got transferred from my backups to newer phones, but since my iPhone 4 I've collected a total of 14 blocked contacts (also not sure if the iPhone 4 was already able do this). Otoh, the U.S. got iphone mirroring.

EXACTLY there should never be a limit of how many you can block.

Exactly, there should never be limit. You should be allowed to block how ever many u want
Somewhere, there is a server look-up table that has to reference those blocked contacts. And that takes time/processing power. Do you want the number to cross-reference 45,902,345 number variations every time someone calls you? That costs money, and can lead to instability, unless you limit it to a reasonable amount.

I wish I could have just 10% of that blocked contact limit for creating HME iCloud email addresses.

It tops out at ca 745 today.

If you use these faithfully for personal business related things like all online accounts and backup addresses, etc. it’s REALLY REALLY easy to hit this limit (this is even though for personal contacts I just use my old yahoo acct).
