How Can I Block My Number? | Private Call Guide

Guide / By

To block your number, dial *67 before the call, turn off caller ID in phone settings, or enable a carrier block.

Hiding your caller ID stops your number from showing up on the other side. You can do it per call with a quick code, across all calls with a setting in your phone, or at the account level through your carrier. Some lines and services always see your number, so you’ll also find clear limits and fixes below.

Quick Ways To Block Your Number Right Now

Fast pick: Use the option that matches your device or situation. The first method works on almost any line in North America.

  1. Add *67, then the number — Open the dialer, enter *67 + full number, and place the call. Your ID shows as “Private,” “Blocked,” or “Unknown” on most phones. This won’t hide you from toll-free numbers or emergency services.
  2. Turn Off Caller ID On iPhone — Go to Settings › Phone › Show My Caller ID and toggle it off. If you don’t see the switch, your carrier may restrict it.
  3. Hide Number On Android — Open the Phone app › menu › settings; find Caller ID (or Show your caller ID) and select Hide number/Never. Menu names vary by model.
  4. Ask Your Carrier For A Line-Level Block — Many carriers let you enable permanent caller ID blocking in account tools; you can still show your number for one call with *82.
  5. Use A Second Number — Google Voice can place calls with anonymous caller ID or from a virtual number, which keeps your personal line out of sight.

How Can I Block My Number On Any Phone?

For a one-off private call, prefix the destination with *67, then dial. The network flags your call to hide presentation on the recipient’s phone. It’s free, fast, and widely supported on mobile and landline lines under the North American Numbering Plan.

Heads-up: *67 doesn’t hide your number from toll-free lines or emergency services, and some lines reject anonymous calls entirely. You may hear a message asking you to re-dial with your number visible.

When you need your number to appear on a single call after enabling a permanent block, dial *82 before the number to override the block for that call.

iPhone: Hide Caller ID Without Apps

iOS includes a built-in switch to hide caller ID. Many carriers allow it; some remove the toggle in their profile.

  1. Open Settings — Tap Settings on your iPhone.
  2. Go To Phone — Tap Phone, then Show My Caller ID.
  3. Turn It Off — Switch off Show My Caller ID. Your number stays hidden on outbound calls until you turn it back on.

Missing switch? Some carriers (e.g., certain Verizon lines) manage caller ID at the account level, so the iPhone toggle won’t appear. In that case, use *67 per call or enable a line-level block in your account.

  • Show your number for one call — Dial *82 + number to present your caller ID when you’ve set a permanent block.

Android: Hide Caller ID On Most Models

Android phones offer a caller ID visibility control, though the exact path differs across brands and versions.

  1. Open The Phone App — Launch the dialer.
  2. Find Caller ID Controls — Tap the menu; go to settings › Supplementary services or Calls › Caller ID/Show your caller ID.
  3. Select Hide Number — Choose Hide number or Never to hide your ID for all calls. To reveal it for a single call, dial *82 before the number.

You can also place private calls with *67 at any time, which works across Android models and most carriers.

Taking An Alternate Route: Close Variations Of “How Can I Block My Number” With Extra Control

Sometimes you need stronger privacy than a simple prefix. The options below add flexibility, scheduling, and caller ID choice when “how can I block my number” alone doesn’t cover your use case.

  • Use A Second Line App — Google Voice lets you call from a different number or enable Anonymous caller ID within the app’s settings.
  • Turn On Carrier Spam Tools — T-Mobile Scam Shield and similar tools reduce callbacks and shield your primary line identity during screening.
  • Block Numbers You Don’t Want Calling Back — Combine caller ID hiding with OS-level number blocks to keep spam and unknown callers from reaching you later.

Carrier Tools And Star Codes That Matter

Quick reference: common codes and account options used across major carriers. Use the table first; details follow below.

Carrier Or Context Per-Call Hide Per-Call Show
Any NANP line (most US/CA) *67 + number *82 + number
Verizon (account option) *67 or enable “Caller ID Blocking” in account *82 for one call
AT&T (star codes) *67 then number *82 then number
T-Mobile *67 then number *82 then number

Verizon lines can turn on Caller ID Blocking inside the account or My Verizon app. AT&T and many landlines publish star codes that match *67 for hiding and *82 for showing. T-Mobile lists the *67 method and offers app-based controls.

Limits, Regional Codes, And Fixes When It Doesn’t Work

Always visible targets: toll-free numbers and emergency services see your number even when you try to hide it. The display to the recipient may still show “Private,” but the network retains your number.

  • Anonymous Call Rejection — Some phones or landlines refuse blocked calls. If the line rejects your call, re-dial with *82 to present your ID once.
  • Carrier Removes The iPhone Toggle — If the iOS Show My Caller ID switch is missing, use *67 per call or set the block in your account.
  • International Variations — Prefixes differ outside NANP regions: the UK and Ireland use 141; many GSM mobiles accept #31# before the number. Check your local carrier’s code list.
  • Apps And Privacy — Third-party call apps can help, though they may need contact and call access. Built-in carrier spam tools (e.g., Scam Shield) reduce nuisance callbacks.

Yes. Dial *82 before the number to present your ID on that call.

Where Does “How Can I Block My Number?” Appear In My Account?

Look for caller ID settings in your carrier account dashboard or app; Verizon labels it “Caller ID Blocking,” with a simple on/off switch per line.

If you landed here asking “how can I block my number?”, you now have fast prefixes, system toggles, and carrier options you can use with confidence.
