iPhone
Tired of call center calls? Type the prefix they call from and iOS blocks every number that starts with it, silently, even when the app is closed.
Call Centers Block stops the calls you keep getting from the same number ranges. You enter a prefix, for example 0584177, and iOS blocks every incoming call whose number starts with it.
WHAT DECIDES WHAT GETS BLOCKED
Only you. The app ships with no list of numbers and downloads none. The only blocking criteria are the prefixes you type in yourself, for the ranges that have actually been calling you. You can edit or delete any of them at any time.
TWO MODES FOR EVERY PREFIX
Block: matching calls never ring. Nothing interrupts you.
Identify: matching calls still ring, but the call screen shows which prefix matched, so you decide whether to answer.
HOW IT WORKS
iOS never lets an app inspect a call while it is ringing. So the app expands each prefix on your iPhone into all the numbers it covers and hands that list to iOS through Apple's Call Directory system. From then on iOS filters the calls by itself, even when the app is closed. A seven digit prefix covers 11,111 numbers, and the app shows you exactly how many numbers a prefix covers before you add it.
PRIVACY
Nothing is collected, transmitted or shared. There is no account, no analytics, no advertising and no network connection at all. Your prefixes never leave your iPhone. The app never sees who is calling you, because iOS does the matching.
WORTH KNOWING
- iOS never blocks numbers saved in your Contacts, whatever prefix you add.
- On recent versions of iOS, a number you have called yourself is not blocked until you delete that outgoing call from Recents.
- WhatsApp, FaceTime and similar app calls do not go through the system call filter, so they are not affected.
- A blocked call may still be listed in Recents as Blocked. It never rings.
- A Diagnostics section shows when iOS last loaded your list and how many numbers it contains, so you can confirm it is working.
Works with any country code. Numbers typed without a leading + are treated as numbers from the country you pick in Settings.
