My first blocked number is showing as most recent in iOS 18.5

On an iPhone, there is no dedicated section called “Recently Blocked” where you can see the numbers you just blocked. Once you block a contact or phone number, it is simply added to your overall Blocked Contacts list, which is found under Settings > Phone > Blocked Contacts (or Settings > Messages/FaceTime > Blocked Contacts depending on the app). This list is cumulative and shows all the numbers and contacts you’ve blocked, but it does not highlight or sort them by when they were blocked. If you need to track when a number was blocked, unfortunately, iOS does not provide a timestamp or “recently added” filter for that — you would need to remember the action or keep your own record separately.
