Hide Caller ID on Android Phones: Using in-built settings

Hide Caller ID on Android: A Comprehensive GuideIn today’s privacy-conscious world, knowing how to hide caller ID on Android devices is essential. Whether you’re calling a business, reporting an issue, or want to maintain anonymity, You can also use Android 16 latest features that offers multiple methods—some built-in and others via apps or carrier services. This article walks through each method step by step, ensuring you can mask your phone number whenever necessary.

Hide Caller ID via Android Settings

Why Use Settings?

Choosing to hide caller ID through settings saves you from entering codes every time. It’s a global, one-time setup that applies to all outgoing calls—except emergency and toll-free numbers.

Where to Find the Option

Though UI varies by device, the general path is:

• Open the Phone app.
• Tap ⋮ (three-dot menu) → Settings.
• Go to Calls, Calling Accounts, or Supplementary Services.
• Tap Additional Settings (if present).
• Select Caller ID.
• Choose Hide number, Never, or similar wording instead of “Network default” or “Show number”.

Once configured, all your outgoing calls will appear as “Private,” “Unknown,” or “Blocked” to recipients. To reverse, choose “Show number” or “Network default”.

Limitations: Not all Android builds or carriers support this option. Emergency calls (e.g., 112 in India, 911 in the US) bypass the block.

Hide Caller ID for a Single Call Using Prefix Codes

Why Use Prefix Codes?

Need anonymity only occasionally? Prefix codes let you hide caller ID on a per-call basis—no need to change settings.

Common Prefix Codes by Country

Region	Prefix Code
US, Canada	*67
UK, Ireland	141
Most Europe	#31# or *31#
India	#31#

To use: dial the prefix before the number—e.g., #31#1234567890

Note: these codes won’t work for toll-free numbers or emergency services, and some recipients may reject hidden calls.

Use Google Voice for Anonymity

Google Voice allows you to hide caller ID by using an alternate number:

1. Install and open Google Voice.
2. Go to Settings → Calls.
3. Enable Anonymous caller ID.

All calls through Google Voice then show as anonymous or show the Google Voice number instead of your real number.

Ideal for those who need recurring anonymity without prefix codes or settings changes.

Use Burner/Temporary Number Apps

Apps like Burner, Hushed, Dingtone, or CoverMe provide disposable numbers that protect your real caller ID. Here’s how they work:

• Install from Play Store.
• Create an account and select a temporary number.
• Use the app to dial—recipients see the burner number, masking your original one.

Great for one-off deals, online dating, or sensitive calls. Many services offer limited free minutes; subscriptions unlock more.

Ask Your Carrier to Block Caller ID Permanently

Some carriers support network-level hide caller ID:

1. Call or visit your provider’s customer support.
2. Request permanent Caller ID blocking on your line.
3. Provide verification details.

Once activated, your number is blocked by default on every call—no code needed. Some carriers may charge a nominal fee.

Pros: Always-on privacy.
Cons: Some callers may reject hidden calls; rates may apply.

Using Dial Codes to Toggle Caller ID Programmatically

Advanced users can use secret codes like:

• *#31# – hide permanently (code executed via dialer)
• #31#phonenumber – hide for that call
• *31#phonenumber – unhide for that call

These aren’t universal—availability depends on OS version and carrier. Use with caution; test in your region first.

Limitations & Special Cases

Emergency or Toll‑Free Numbers

Your number can’t be hidden when calling emergency services (e.g., 112, 911) or toll-free lines .

Recipient Preferences

Some recipients reject calls from hidden numbers. Even with settings active, they may simply not answer .

Carrier/Region Lockouts

In some countries (e.g., India), settings may be disabled by default. Codes like *67 or #31# may still work if supplementary services are accessible.

Legal & Ethical Considerations

Using anonymity tools to commit fraud is illegal. In India, for instance, CLI spoofing is a punishable offense . Always ensure your intent is lawful.

Protecting Against Spoofing

While you learn how to hide caller ID, it’s equally important to guard against caller ID spoofing—when scammers fake IDs. Protect yourself by:

• Enabling Android’s Caller ID & Spam Protection in Settings.
• Using third-party apps like Truecaller, Robokiller.
• Checking your bill regularly and reporting suspicious call.
