Published : February 26, 2025

Wondering if *67 still works in 2025? The short answer is yes, but there are some things you should know. Dialing *67 before a phone number hides your caller ID, showing “Private” or “Blocked” on the other person’s phone. It’s a handy trick for staying anonymous, but it doesn’t work in all situations, like when calling emergency numbers or toll-free lines.

If you’re curious about how *67 compares to *69, whether it costs money, or why it might not work on your iPhone, this blog has all the answers. We’ll also cover alternatives and how to hide your number on both iPhone and Android devices.

What Is Star 67?

Dialing *67 before a phone number hides your caller ID, so the person you’re calling will see “Private” or “Blocked” instead of your number. It works on landlines, iPhones, and Android devices but not when calling toll-free numbers or emergency services. If the person you’re calling has blocked anonymous calls, *67 won’t work either.

While *67 hides your number from the person you’re calling, phone companies can still trace the call. The good news is that using *67 is completely free, but you will need to dial it every time you want to keep your number private.

What Does Star 67 Do?

Dialing *67 before a phone number hides your caller ID, so the person you’re calling will see “Unknown” or “Blocked” instead of your number. This trick works on most phones, including iPhones. But whether it works or not depends on your service provider—some carriers might not support it.

It’s important to know that *67 only hides your number from the person you’re calling. It doesn’t make you completely anonymous. Your call can still be traced by phone companies or authorities if needed.

If *67 isn’t working on your iPhone, it could be due to settings on your device or restrictions from your carrier. Also, using *67 is usually free, but it’s a good idea to check with your service provider just in case.

How Does Star 67 Hide Your Caller ID?

Dialing *67 before a phone number hides your caller ID, making your number show up as “Private” or “Blocked” on the other person’s phone. It’s a quick and easy way to keep your number confidential, whether you’re using a landline or mobile phone. Here’s how it works and what you should know:

• How It Works: When you dial *67 before the number, it sends a request to your phone carrier to block your caller ID for that specific call. This happens instantly and is only temporary, meaning your number will show normally on your next call unless you dial *67 again.
• When It’s Useful: This is handy if you don’t want the person you’re calling to know your number. For example, if you’re making a business inquiry or contacting someone, you don’t know well.

Limitations to Keep in Mind

• It doesn’t work for toll-free numbers (e.g., 800, 888) or emergency services like 911. These numbers will still see your caller ID.
• It only hides your number for that one call. If you want to hide your caller ID for all outgoing calls, you’ll need to change the settings on your phone.

Does *67 Still Work?

Yes, *67 still works in 2025! If you dial *67 before a phone number, it hides your caller ID, so the person you’re calling sees “Private” or “Blocked” instead of your number. This works on both iPhone and Android devices.

However, keep in mind that it doesn’t work for all calls. For example, some phone carriers don’t support it, and it won’t hide your number if you’re calling emergency services. Also, if the person you’re calling has settings that block anonymous calls, your call might not go through. It’s a good idea to check with your phone carrier if you’re unsure.

When Does Star 67 Not Work?

Star 67 is a handy trick to hide your phone number when making a call, but it doesn’t always work. Here are some common situations where Star 67 might fail:

• Emergency Numbers: If you’re calling 911 or other emergency services, your number will always show up. This is for safety reasons so that they can help you faster.
• Toll-Free Numbers: Calling 1-800, 1-888, or other toll-free numbers will not hide your number. These lines use special systems that pick up caller IDs no matter what.
• Businesses with Caller ID Systems: Some companies have advanced caller ID systems that reveal private numbers, even if you use Star 67.
• Call Blocking Apps: If the person you’re calling uses an app that blocks anonymous calls, your call might not go through.
• International Calls: Not all mobile carriers support Star 67 for international calls, so your number could be displayed.
• Network Limitations: Some carriers simply don’t support Star 67 on certain types of calls, even within the same country.

Star 67 can be useful, but it’s not a guarantee for privacy. If staying anonymous is crucial, consider other options like temporary phone numbers or privacy-focused calling apps.

What Are *67 Alternatives?

If you want to keep your phone number private when making calls, there are several ways to do it besides using *67. Here’s how you can easily hide your number on both iPhone and Android devices.

Alternatives to *67

1. Caller ID Blocking: Most smartphones let you block your caller ID right from the settings. This stops your number from showing up on the other person’s phone.

2. Virtual Phone Numbers: Apps like Google Voice let you make calls using a different number, keeping your real number hidden.

Detailed Comparison: 67 vs. Alternatives (CallHippo, Google Voice, Burner, Built-In Settings)

Using *67 is a quick way to block your caller ID, but it has its limitations, like working only on a per-call basis and not supporting texts or voicemails. There are other options, like CallHippo, Google Voice, Burner, and built-in phone settings, which offer more features and flexibility.

Here’s a detailed comparison to help you decide which solution best suits your needs.

If you need a simple, temporary solution, *67 or Burner might work. However, for more advanced features, better security, and international calling, CallHippo is the best choice.

It offers the most comprehensive set of features for both personal and business needs, ensuring privacy without compromising functionality.

Troubleshooting Common Issues with *67

If *67 isn’t working when you try to hide your caller ID, don’t worry—there are a few common reasons and simple fixes. Here are some common problems and solutions:

1. Incorrect Dialing: Make sure you’re entering *67 before the complete phone number, including the area code. For example, dial *67-123-456-7890. If you skip the area code, it might not work.

2. Carrier Restrictions: Some phone carriers don’t support *67 for certain types of calls, like international numbers or toll-free lines.

Solution: Test *67 with a local number first. If it works locally but not for other calls, your carrier might have limitations. Contact your carrier for details.

3. Phone Settings Issue: On smartphones, your device settings might override *67.

Solution: Go to your phone’s call settings and make sure caller ID blocking is enabled. Restart your phone, as this can fix temporary glitches.

4. Anonymous Call Blocking: If the person you’re calling has blocked anonymous calls, your call won’t go through.

Solution: In this case, *67 won’t work, and you’ll need to call without blocking your number.

If problems continue, consider using alternatives like #31# (for GSM networks) or third-party apps for private calls. These steps should help you resolve most *67 issues.
