Block number on iPhone: Sometimes, the best way to avoid people is to straightaway block their contact on your phone. Whether they are stalking you, or disturbing you, or you simply want to cease communications with a certain person for whatever reasons, blocking their number is an easy and effective way to achieve that. Blocking a number has been long available on Android devices and feature phones for years. The option exists on iPhones too and we will tell you how you can do it.

Blocking someone's contact number on the iPhone is an easy process. However, it requires you to follow some simple steps to do the same. When you block someone's contact number, you won't be able to get calls, texts, or FaceTime requests from the blocked number. If you have a voicemail set, their calls will be diverted to that but it will never reach you. The voicemail gets stored on the iPhone and is hidden from your regular voicemail.

Also, note that blocking a number from the iPhone will not block it from accessing other services such as WhatsApp, Facebook or Instagram. You need to go to your respective account and do the process manually from their settings.
