Whether it's an acquaintance you’d rather not hear from, or a pushy telemarketer, knowing how to block a number on an Android phone is pretty useful.

The ability to block a number is not reserved just for the best phones built on Google's Android operating system, it’s a standard feature on practically all devices nowadays. Still, if you’re unsure how to do it, or if you’ve just moved from an Apple smartphone and looking to pick up on the basics, we’ve got you covered.

The first thing to know is that there are two ways of blocking a number both from texting or calling you. This depends if you have that number saved in Contacts or not. We’ll go through both options, so you’ll have all the bases covered. Also, bear in mind that different Android phones tend to have different UIs. They might not be drastically different but just keep that in mind if the images down below don’t look 100% the same as the ones on your phone.

Not an Android user? We've also put together a guide on how to block a number on an iPhone.
