How Can You Block Your Number When Calling? (2025 Guides)

Have you ever wondered how to keep your phone number private when making a call? Whether you want to protect your privacy or avoid revealing your identity temporarily, blocking your number is a simple and effective solution. Let’s explore step-by-step methods to block your number on any device, with tips and insights for both smartphones and landlines.

Why Block Your Number When Calling?

Blocking your number can serve various purposes:

  • Privacy: Protect your personal information from strangers.
  • Avoid Callback Hassles: Prevent unwanted return calls.
  • Professional Reasons: Keep business and personal communication separate.

Whatever your reason, knowing how to block your number ensures you have control over your privacy.

How to Block Your Number Temporarily

1. Use a Code Before Dialing

One of the easiest ways to block your number is by adding a code before the number you’re dialing.

  • For the US and Canada: Dial *67 before the number.
    Example: Dial *67 123-456-7890.
  • For the UK and Ireland: Dial 141 before the number.

This method works on most carriers and hides your number for a single call. Note: It does not work for emergency services or toll-free numbers.

2. Use Your Phone Settings

Most smartphones let you block your number directly in the settings.

For iPhones:

  1. Go to Settings.
  2. Tap Phone.
  3. Select Show My Caller ID.
  4. Toggle the switch Off.

For Android Phones:

  1. Open the Phone app.
  2. Tap the Menu (three dots) icon.
  3. Select Settings > Call Settings.
  4. Choose Caller ID and select Hide Number.

These settings apply to all outgoing calls unless reversed.

How to Permanently Block Your Number

Contact Your Carrier

If you want to block your number for all calls permanently, your service provider can help. Contact customer support and request number blocking. Some carriers may charge a fee for this service.

  • Pros: No need to adjust settings for each call.
  • Cons: Not flexible; all calls will show as private.

Use Third-Party Apps

Several apps provide enhanced privacy features, including permanent number blocking.

  • Examples:
    • Burner
    • Hushed

These apps also let you create temporary numbers for added privacy.

When You Can’t Block Your Number

Some scenarios may prevent you from blocking your number:

  • Emergency Numbers: Calls to services like 911 or 112 will always display your number for safety.
  • Toll-Free Numbers: Businesses with 1-800 or similar numbers will still see your caller ID.
  • Unblocking by Recipients: Advanced systems or apps can reveal hidden numbers.

Alternative Methods

If blocking fails, consider these options:

  • Use a different phone or SIM card.
  • Opt for a temporary virtual number through apps.
