How To Block Your Number

In an era where personal data is a hot commodity, ensuring one’s privacy becomes not just a luxury but a necessity.

The act of blocking one’s phone number, while seemingly simple, can be a potent tool in a variety of scenarios.

From dodging pesky telemarketers to safeguarding oneself in potentially risky situations, this guide will provide an in-depth look into the nuances of blocking your number across various devices and platforms.

Reasons to Block Your Number

Understanding the motivation behind blocking one’s number can provide clarity on its importance:

Avoiding Spam and Telemarketing Callbacks

Unsolicited calls can be more than just an annoyance; they can disrupt your day, waste your time, and even pose security risks.

By blocking your number during inquiries, you can reduce the chances of being bombarded with unwanted callbacks.

Personal Safety

There are instances when sharing your number can be risky.

Whether you’re dealing with a stranger, an online transaction, or escaping a potentially harmful situation, keeping your number hidden can be a protective measure.

Making Anonymous Calls

Both businesses and individuals occasionally need to make calls without revealing their identity.

This could be for market research, anonymous feedback, or personal situations where discretion is paramount.

Blocking Your Number on Mobile Devices

iOS (iPhone)

Apple’s iOS provides a straightforward method:

  1. Launch the ‘Settings’ app on your iPhone.
  2. Navigate and tap on the ‘Phone’ section.
  3. Within this menu, you’ll find the ‘Show My Caller ID’ option. Toggle this off to block your number.
  4. To confirm the change, place a test call. If done correctly, your number should display as ‘Unknown’ or ‘Private’ to the recipient.


Android devices, given the variety of manufacturers, might have slight variations in the process:

  1. Start by opening your ‘Phone’ app.
  2. Access ‘Settings’ or the three-dot menu, typically found at the top right.
  3. Dive into ‘Additional settings’ or ‘Call settings,’ depending on your device.
  4. Here, you’ll find the ‘Caller ID’ option. Choose the ‘Hide number’ setting.
  5. As a precaution, make a test call to ensure your number appears blocked.

Blocking Your Number on Landlines

Temporary Blocking

For those moments when you need a one-off number block:

  1. Dial *67 followed by the number you intend to call.
  2. It’s worth noting that this method may not always work, especially with toll-free numbers or certain service providers.

Permanent Blocking

For those who prefer a more lasting solution:

  1. Reach out to your landline service provider’s customer service.
  2. Express your desire for permanent caller ID blocking.
  3. Once activated, if there’s ever a need to unblock for a specific call, you can dial *82 before the desired number.

Using Third-Party Apps and Services

For those seeking advanced features or more control, several third-party solutions can assist:

Burner: Beyond just blocking, Burner provides users with temporary phone numbers. This is especially useful for scenarios like online selling, dating, or any situation where a temporary number is more appropriate than your personal one.

Hushed: Akin to Burner, Hushed takes it a step further with features like customizable voicemail greetings and the ability to send and receive texts.

While these apps can be incredibly beneficial, it’s crucial to be aware of their terms of service, potential costs, and any data they might collect.

Unblocking Your Number

If you’ve chosen to block your number but find yourself needing to revert:

iOS and Android: Navigate back to the settings mentioned earlier and toggle the ‘Show My Caller ID’ or ‘Hide number’ option to its original position.

Landlines: For specific calls where revealing your identity is necessary, simply dial *82 before the intended number.

Tips and Precautions

Always stay informed about the legal implications of making anonymous calls. Misusing blocked numbers for deceitful activities is not only unethical but also illegal in many jurisdictions.

Mutual respect is key. Just as you cherish your privacy, ensure you’re not infringing upon someone else’s without valid reason.

Be prepared for potential roadblocks. Some services, businesses, and even individuals may have settings that reject calls from blocked numbers. It’s always good to have an alternative communication plan in place.


The ability to block and unblock your number is more than a mere technological feat; it’s a testament to the evolving needs of our digital age.

As our world becomes increasingly interconnected, the value of privacy and discretion cannot be overstated.

However, with such capabilities at our fingertips, it’s imperative to wield them responsibly and ethically.
