Privacy is a weird thing. One minute you're happily giving your digits to a grocery store rewards program, and the next, you're wondering, how do i block my number before calling that sketchy Craigslist seller or a client on your personal cell? We've all been there. It feels a bit like wearing a digital disguise. Sometimes you just don't want your personal life bleeding into your professional interactions, or maybe you're just tired of your number ending up on every telemarketer's lead sheet from Hoboken to Hong Kong.
Honestly, the "why" doesn't matter as much as the "how." Whether it’s a one-time thing or a permanent lifestyle choice, hiding your caller ID is actually pretty easy, though the methods vary depending on your hardware and your carrier.
The Magic of Star Codes
If you just need a quick fix for a single call, the legendary *67 is your best friend. It’s been around since the days of corded wall phones and it still works like a charm. You just tap in *67, followed by the area code and the phone number.
The person on the other end won't see your digits. Instead, they'll see "Private," "Blocked," or "Anonymous" popping up on their screen. It's free. It's fast. Most importantly, it's temporary. The very next call you make without the code will show your number perfectly fine.
There's a catch, though. This doesn't work for toll-free numbers or emergency services. If you call 911, they're going to see exactly who you are, which is probably for the best if you're in a pinch. Also, some people—myself included—rarely answer "Anonymous" calls because we assume it’s a debt collector or someone trying to sell us an extended car warranty. If you’re trying to reach a friend, they might just ignore you.
Diving Into Smartphone Settings
If you're asking how do i block my number because you want it hidden for every call, digging into your phone's settings is the way to go. It’s way more convenient than typing a code every single time.
For the iPhone Crowd
Apple makes this fairly straightforward, but they hide it deep in the menus. Go to Settings, scroll down until you hit Phone, and then look for Show My Caller ID.
You'll see a simple toggle. Flip it off. Now, every single person you call will see you as a mystery guest. Just keep in mind that this setting is carrier-dependent. If the toggle is greyed out or just flat-out missing, your carrier (looking at you, some prepaid MVNOs) might have locked that feature down. In that case, you have to go through their app or call their support line to get it handled.
The Android Experience
Android is a bit of a wild west because every manufacturer—Samsung, Google, OnePlus—likes to move things around. Generally, you’ll open the Phone app, hit those three little dots in the corner for the menu, and go to Settings.
From there, look for Supplementary services or Calling accounts. You should find an option for Caller ID. Tap it and select Hide number.

It’s worth noting that if you use a Google Pixel, the menu might look slightly different than a Samsung Galaxy, but the logic remains the same. Search for "Caller ID" in the settings search bar if you get lost; it’s a lifesaver.
When Your Carrier Holds the Keys
Sometimes software tweaks aren't enough. If you’re serious about privacy—maybe you’re a doctor returning calls from home or a teacher contacting parents—you might want a permanent block at the network level.
Major carriers like Verizon, AT&T, and T-Mobile allow you to manage this through their web portals. Log in to your account, find your device management page, and look for "Block Caller ID." This ensures that even if you switch phones, your privacy settings stay intact.
Verizon calls it "Caller ID Blocking." It's usually free, but some "premium" versions that show a generic name instead of "Private" might cost a couple of bucks a month.
The Burner App Alternative
Let’s be real: blocking your number is sometimes a bit suspicious. If you’re trying to run a small business or a side hustle, you don't want to show up as "Anonymous." People won't pick up.
This is where secondary number apps come in. Apps like Burner, Hushed, or Google Voice give you a legitimate second phone number that rings through to your primary device.
Google Voice is arguably the best for this because it's free (for personal use) and gives you a real, local number. When you call out from the Google Voice app, the recipient sees that secondary number. Your actual, private cell number stays hidden, but you still look like a real person with a real area code. It’s the "pro" way to answer the question of how do i block my number without actually blocking it.
The Limits of Anonymity
Don't get it twisted: blocking your number isn't a superpower. There are plenty of ways people can circumvent your "Private" status.

There are services out there like TrapCall. They basically unmask blocked numbers by rerouting the call through a toll-free line before sending it back to the user. It’s commonly used by people dealing with harassment, but it means your *67 isn't foolproof.
Also, if you're harassing someone, your carrier still has the logs. If the police get involved, they don't care if you used a code; they can see the metadata. Privacy is for protection, not for being a nuisance.
Technical Nuances You Should Know
It is important to understand that "blocking" your number for outgoing calls is entirely different from "blocking a contact." I see people get these confused all the time.
If you block a contact on your phone, you're telling your phone to ignore them. If you block your number, you're telling the network to hide you.
Also, international calls are a toss-up. If you use *67 to call someone in the UK or Japan, the local carriers there might not recognize the "hide" command from a US-based network. Your number might leak through, or the call might just fail to connect entirely because of local regulations.
Practical Next Steps
If you want to start hiding your identity right now, here is the most logical path forward.
First, try a test call. Use *67 and call a friend or your own work phone. See how it looks. If it works and that's all you need, you're done.

If you find yourself needing to hide your number daily, go into your iPhone or Android settings as described above. It takes thirty seconds and saves you the hassle of typing codes.
For those who need a professional "mask," go sign up for a Google Voice number. It’s the most robust way to keep your personal life private while still being reachable. Just make sure you actually set the "Outbound Caller ID" in the Google Voice settings to show your GV number and not your carrier number.
Lastly, check your carrier's app. If you’re paying for a line, you might as well see what privacy features are included in your plan for free. Most modern plans include basic caller ID masking if you just know where to click.
Keep in mind that digital privacy is a moving target. What works today might change with the next OS update, so it’s always smart to double-check your settings every few months just to make sure you aren't accidentally broadcasting your digits to the world.
