Original Title: Clearing blocked contacts

sberman is correct. On iPhone, you can clear blocked numbers one at a time. But if you own a Mac, you can clear numbers in large blocks or all numbers at once.

The fact you have reached 3000 blocked numbers indicates you've been blocking spam calls, which is a totally ineffective waste of time. Spammers don't call from the number you see. They Spoof their numbers, so blocking them is getting you nowhere.

Instead use the Call Blocking and Screening tools which were released in iOS 26 as the only affective way to minimize the spam calls. See how to use them here --> Screen and block calls on iPhone - Apple Support

Unblock them one by one.

Blocking telephone numbers from spam callers doesn’t work, as the spammers rarely call from the same number more than once.
