How Do I Block My Number When Calling?
Want to keep your phone number private? You can block your number easily before making a call using a simple code or phone settings, protecting your anonymity.
Introduction: The Power of Private Calling
In today’s world, privacy is paramount. Whether you’re making a call for business negotiations, contacting a new acquaintance, or simply wanting to avoid future unwanted solicitations, controlling your caller ID can be invaluable. Understanding how to block your number when calling allows you to maintain control over your personal information and manage who has access to your contact details. It’s a simple yet powerful tool for privacy protection in the digital age.
Why Block Your Number? Benefits and Considerations
There are numerous valid reasons why you might want to hide your phone number when making a call. These reasons often fall into a few key categories:
- Privacy Protection: Preventing unwanted callers from obtaining your number and potentially using it for spam or harassment.
- Business Negotiations: Maintaining a degree of anonymity during sensitive business dealings.
- Confidentiality: Making calls to sensitive services or support lines where you prefer not to share your personal information.
- Avoiding Retaliation: In some situations, blocking your number may protect you from potential retaliation or unwanted contact after making a call.
While blocking your number can be beneficial, it’s important to consider the potential drawbacks. Some recipients may be hesitant to answer calls from blocked numbers, assuming they are spam or robocalls. In emergency situations, emergency services may not be able to easily trace your location.
The Simple Code: 67 and #31
The most common and universal method for blocking your number on a per-call basis is using a shortcode. The most widely used code is 67. Before dialing the number you wish to call, simply enter 67 followed by the ten-digit phone number (including the area code).
Example: To call 555-123-4567 and block your number, you would dial 675551234567.
In some regions, an alternative code, #31#, may be used for the same purpose. It’s always best to check with your local phone service provider to confirm which code is appropriate for your area.
Blocking Your Number Through Phone Settings (Permanent Blocking)
Most modern smartphones offer a setting that allows you to block your number for all outgoing calls. This is a more permanent solution than using the 67 code and requires more effort to disable.
Here’s a general overview of how to find this setting on both iOS (Apple) and Android devices:
iOS (iPhone):
- Open the Settings app.
- Scroll down and tap on Phone.
- Find and tap on Show My Caller ID.
- Toggle the switch to the Off position.
Android (varies slightly by manufacturer and OS version):
- Open the Phone app.
- Tap on the Menu icon (usually three dots in the upper right corner).
- Select Settings.
- Look for options like Call Settings, Supplementary Services, or Caller ID.
- Select Caller ID or Show My Number.
- Choose Hide Number or Default.
Important Note: The exact location and wording of these settings may vary depending on your specific phone model and operating system version. Refer to your phone’s manual or online support resources for detailed instructions if needed.
Temporary vs. Permanent Blocking: Which is Right for You?
The choice between using the 67 code (temporary) and enabling the setting on your phone (permanent) depends on your individual needs.
| Feature | Temporary Blocking (67 Code) | Permanent Blocking (Phone Settings) |
|---|---|---|
| Blocking Scope | Single Call | All Outgoing Calls |
| Ease of Use | Quick and Easy | Requires Navigating Phone Settings |
| Flexibility | High, choose per call | Low, all or nothing |
| Best For | Occasional privacy needs | Consistently protecting your number |
If you only need to block your number occasionally, the 67 code is the simplest option. If you consistently want to hide your number, enabling the setting on your phone is more convenient. Remember, you can always toggle the phone setting on and off as needed.
Common Mistakes to Avoid
While blocking your number when calling is generally straightforward, there are a few common mistakes to avoid:
- Forgetting the 67 Code: Always remember to dial the code before dialing the phone number.
- Dialing the Code Incorrectly: Ensure you are entering the correct code (67 or #31#) and dialing it accurately.
- Using the Wrong Settings: Make sure you are navigating to the correct settings in your phone’s menu.
- Assuming Blocking Works Everywhere: Some services, like emergency services, may still be able to see your number even when it’s blocked.
- Not Testing the Blocking: After enabling the setting on your phone, test it by calling a friend or family member to confirm that your number is indeed being blocked.
Beyond Blocking: Other Privacy Considerations
Blocking your number when calling is just one aspect of protecting your privacy. Consider the following:
- Using a Burner Phone: For situations where you require a temporary or disposable phone number, consider using a burner phone or a burner app.
- Managing App Permissions: Review the permissions granted to apps on your phone and revoke access to sensitive information like your contacts and location.
- Being Mindful of Social Media: Be cautious about sharing personal information on social media platforms.
- Using a VPN: Consider using a Virtual Private Network (VPN) to encrypt your internet traffic and protect your online privacy.
Frequently Asked Questions
Will 67 block my number every time?
Yes, 67 will block your number, but only for the single call you are making. You need to dial it before each call where you want to block caller ID.
Does blocking my number work internationally?
Whether blocking your number works internationally depends on the phone systems of the country you are calling. Some countries ignore the caller ID blocking request, so your number may still be visible.
Will blocking my number prevent spam calls?
Blocking your number does not directly prevent spam calls. Spammers often use spoofed numbers or robocalls, which are not affected by caller ID blocking. However, it can prevent spammers from acquiring your specific number if you initiate a call.
Can emergency services see my number if it’s blocked?
In most cases, emergency services are able to see your number even if it’s blocked. This is to ensure they can locate you in case of an emergency. This ability supersedes caller ID blocking.
Is blocking my number legal?
Blocking your number is legal in most situations. However, there might be specific circumstances where it’s considered unethical or illegal, such as when used to harass or defraud others.
How do I unblock my number after using 67?
Simply dial the number you want to call without entering the 67 code. Your number will be visible for that call.
What if I am calling a toll-free number? Does blocking still work?
Yes, blocking your number typically works when calling toll-free numbers. However, some toll-free services may still be able to access your number for verification or record-keeping purposes.
Will the person I call know that I’ve blocked my number?
The recipient of your call will typically see a message such as “Private Number,” “Blocked,” or “Unknown Number” instead of your phone number. They will know that you have blocked your caller ID.
I blocked my number but it still shows up. Why?
There are a few reasons why this might happen: Your phone settings might not be configured correctly. You might be calling someone who has caller ID spoofing detection. Sometimes, a system error prevents the block from working. Confirm your settings and test again.
Does 67 work on all phone types (landline, mobile)?
Yes, 67 generally works on both landlines and mobile phones. However, some older landline systems might not support caller ID blocking.
Is there a charge for blocking my number using 67?
Typically, there is no charge for using 67 to block your number on a per-call basis. However, some phone service providers might have specific policies or charges, so it’s always best to check with them directly.
How do I unblock my number permanently if I’ve set it in my phone’s settings?
Follow the same steps to access the caller ID settings in your phone as you did to block it. On iOS, toggle the Show My Caller ID switch to the On position. On Android, select Show Number or the appropriate option to display your caller ID. This reverses the process used to initially block it.
