How to block a number on iPhones and Android phones

There are many reasons to want to block specific numbers on your phone. Whether it's nuisance spam callers, or a particularly persistent ex you no longer want to talk to, the humble Block option is a phone mainstay. It used to be you'd need to contact your carrier to stop a particular number from calling you, but thankfully, it's a lot easier to block numbers in this day and age.

What You Need

Blocking numbers is now built into both Android phones and Apple iPhones, and it's easy to access too, being available directly from your phone dialer. No, you don't need to download a third-party app, or dive deep into your settings. Here's how to block a number on iPhones and Android phones.

How to block calls on an iPhone

You've been able to block contacts and callers on iOS since iOS 7, which means it's available to absolutely everyone using an iPhone — unless you're still using an iPhone 3GS or older. If you are, well, we highly recommend upgrading your iPhone. You won't regret it.

Step 1: To block a caller, head to your Dialer app.

Step 2: Tap Recent.

Step 3: Choose the number or contact you want to block.

Step 4: Scroll down and select Block this caller.

If you want to block an existing contact that isn't in your Recent list, follow these steps.

Step 1: Open the Dialer app again.

Step 2: Choose Contacts.

Step 3: Find the contact you want to block, and select them.

Step 4: Select Block this caller.

How to block calls on an Android phone

Blocking calls on an Android phone is just as easy as on an iPhone, though it's worth noting that different manufacturers will have slightly different processes to follow. However, the general idea will be similar, so you should be able to find the blocking option relatively easily.

Step 1: Open the Dialer or Phone app.

Step 2: Find the contact or number you want to block, and select their icon to open the profile.

Step 3: Choose Block numbers.

As mentioned, it can be slightly different on different phones. Here's how the block process looks on a Samsung Galaxy phone.

Step 1: Again, open the Dialer app and find the contact to block.

Step 2: This time, select it to open it, then choose the "i" button.

Step 3: When the profile is open, select Block at the bottom, and then Block again to confirm.

How to manage blocked numbers on an iPhone

Want to trim down your blocklist, or remove someone now that you've made up? It's easy to remove numbers from your block list. You can head to the individual contact in your contact list and unblock them using the same process as blocking, but if it's not a number you have saved, you can still find them elsewhere.

Step 1: Head to the Settings app.

Step 2: Open Phone or Messages.

Step 3: Find Blocked contacts and select it.

Step 4: You'll find a full list of your blocked numbers and contacts here.

Step 5: To remove one, tap Edit, then the minus sign by the number or contact, then Unblock.

How to manage blocked numbers on an Android phone

As with iPhones, you can simply backtrack the blocking process to unblock a contact, but there's also a list of blocked contacts and numbers you can access to quickly see how many you've blocked.

This process may be slightly different on other manufacturer's phones (we used a Google Pixel for these screenshots), but in general, this guide should be close enough that you can find your way around without much issue.

Step 1: Open your Dialer or Phone app and open the Settings menu by choosing the three-dot menu at the top-right corner.

Step 2: Select Blocked numbers.

Step 3: Now, you can see a full list of your blocked contacts. To unblock one, just select the X by their number, and then confirm by selecting Unblock.

Just like that, you've becoming a number-blocking pro. Blocking numbers on iPhones and Android phones is a much simpler process in 2024 than it used to be, and now, you know everything about it. Good luck and happy number blocking!

Here’s how Apple could change your iPhone forever
An iPhone 15 Pro Max laying on its back, showing its home screen.

Over the past few months, Apple has released a steady stream of research papers detailing its work with generative AI. So far, Apple has been tight-lipped about what exactly is cooking in its research labs, while rumors circulate that Apple is in talks with Google to license its Gemini AI for iPhones.

But there have been a couple of teasers of what we can expect. In February, an Apple research paper detailed an open-source model called MLLM-Guided Image Editing (MGIE) that is capable of media editing using natural language instructions from users. Now, another research paper on Ferret UI has sent the AI community into a frenzy.

There’s a big problem with the iPhone’s Photos app
The Apple iPhone 15 Plus's gallery app.

While my primary device these days continues to be my iPhone 15 Pro, I’ve dabbled with plenty of Android phones since I’ve been here at Digital Trends. One of my favorite brands of phone has been the Google Pixel because of its strong suite of photo-editing tools and good camera hardware.

Google first added the Magic Eraser capability with the Pixel 6 and Pixel 6 Pro, which is a tool I love using. Then, with the Pixel 8 series, Google added the Magic Editor, which uses generative AI to make edits that wouldn’t be possible otherwise. There are also tools like Photo Unblur, which is great for old photographs and enhancing images that were captured with low-quality sensors.
