Have you ever wished to make a phone call without revealing your identity? Whether you’re protecting your privacy, making a surprise call, or handling sensitive matters, anonymous calling can be an incredibly valuable tool. Understanding how to block your caller ID on any device effectively can safeguard your personal information and provide peace of mind.This article dives into the world of anonymous calls, explains how to hide your caller ID, and answers common questions about the process.
Why Hide Your Caller ID?
There are several legitimate reasons why someone might want to prevent their phone number from being displayed when making a call. Some of the most common include:
Protecting Personal Privacy
In today’s digital landscape, unwanted calls, spam, and scams are rampant. If you’re calling an unfamiliar number—such as responding to a classified ad or inquiring about a service—you may not want the recipient to have access to your personal phone number. Hiding your caller ID prevents potential misuse of your contact information.
Security and Safety Concerns
Certain situations demand increased privacy, such as when communicating with unknown individuals, reporting an issue, or dealing with sensitive matters. By keeping your phone number hidden, you reduce the risk of your details being exposed to potential threats.
Professional and Business Use
Many professionals—such as journalists, investigators, legal experts, and counselors—need to keep their phone numbers private to maintain confidentiality. Blocking caller ID ensures that sources, clients, or interviewees don’t have direct access to personal contact details.
Surprise Calls and Gift Arrangements
Sometimes, people simply want to maintain secrecy when planning surprises, organizing gifts, or making anonymous inquiries. Turning off caller ID allows the element of surprise to remain intact.
While these reasons are entirely valid, it’s important to use caller ID blocking responsibly and in compliance with local regulations.

How to Hide Caller ID on Different Devices
Most smartphones and carriers provide options for blocking caller ID, either on a per-call basis or as a permanent setting. Below, we outline various methods for ensuring your number remains private when making calls.
Blocking Caller ID on Android Phones
Android devices offer a built-in option to disable caller ID:
- Open the Phone app on your Android device.
- Tap the three-dot menu in the top-right corner and select Settings.
- Navigate to Supplementary Services or Call Settings, depending on your device model.
- Tap Show Caller ID and select Never to permanently hide your number for all outgoing calls.
Alternative Method: If this option isn’t available, some carriers require caller ID blocking to be enabled through their support services. In that case, you may need to contact your mobile provider.
Blocking Caller ID on iPhones
Apple users can easily disable their caller ID through the phone’s settings:
- Open the Settings app on your iPhone.
- Scroll down and tap Phone.
- Select Show My Caller ID and toggle it off.
This setting ensures that your phone number remains hidden for all outgoing calls. However, if you need to temporarily reveal your number, you’ll have to return to this setting and enable it again.
Using a Block Code for Individual Calls
If you don’t want to hide your caller ID for every call but need to conceal it occasionally, you can use a simple blocking code before dialing the recipient’s number.
To hide your number for a single call:
- *Dial 67 followed by the phone number (e.g., *67-555-123-4567).
This method works with most carriers in the United States and Canada. The recipient will see "Unknown Caller" or "No Caller ID" instead of your phone number.
Carrier-Specific Blocking Codes:
For international calls, check with your carrier to see if a different prefix is required.
| Mobile Carrier | Blocking Code |
| AT&T | *67 |
| Verizon | *67 |
| T-Mobile | #31# |
| Sprint | *67 |
Requesting Caller ID Blocking from Your Carrier
If you need a long-term solution, most mobile carriers offer permanent caller ID blocking upon request. This means that every call you make will automatically have a hidden caller ID unless you specifically enable it for certain numbers.
To activate this service, call your carrier’s customer support and request "permanent caller ID blocking." Some providers may charge a small fee for this feature, while others offer it for free.
| Carrier | Support Number | Caller ID Blocking Service |
| AT&T | 611 | Available upon request |
| Verizon | 611 | Free for postpaid accounts |
| T-Mobile | 611 | Requires additional verification |
| Sprint | 611 | May incur charges |
This option is useful for professionals and individuals who frequently require anonymity in their calls.
Potential Risks and Limitations of Hiding Caller ID
While hiding your phone number offers privacy advantages, it does have a few downsides:
Not All Numbers Accept Anonymous Calls
Some businesses, government agencies, and emergency services block calls from numbers that don’t display caller ID. If you attempt to contact such numbers, your call may be automatically declined.
Higher Likelihood of Ignored Calls
Many people associate "No Caller ID" with spam, robocalls, or scams. As a result, recipients may ignore or reject calls that don’t display a recognizable number.
Still Traceable in Certain Cases
While blocking your caller ID prevents your number from appearing on standard caller displays, law enforcement agencies and some organizations can still trace your number if necessary.
For stronger anonymity, using a VPN alongside caller ID blocking can further enhance your security.
