The short answer is: yes, *67 generally still works in 2023 to hide your phone number on Caller ID systems, but with some important caveats. This classic feature, known as Caller ID blocking, allows you to mask your number on a per-call basis, presenting as “Private,” “Blocked,” or “No Caller ID” to the recipient. However, its effectiveness and the methods of bypassing it have evolved over time, making it essential to understand the nuances of how it functions in the current telecommunications landscape.
Understanding How *67 Works
The *67 prefix, when dialed before a phone number, sends a signal to the telephone network instructing it to suppress your number from being displayed on the recipient’s Caller ID. It is a feature readily available on most landlines and mobile phones. This is a temporary block, meaning your number will only be hidden for the specific call you are making. For future calls, your number will display as usual unless you redial *67.
The functionality of *67 relies on the Caller ID system, which transmits your phone number along with the call signal. By adding *67, you are essentially instructing the system not to include your number in this transmission. This process is relatively simple, making it user-friendly for anyone looking to maintain a level of privacy while making calls.
Limitations and Situations Where *67 May Not Work
While *67 is generally reliable, there are certain situations where it may not hide your number. This is due to advancements in technology and the implementation of call screening and anti-spam measures:
Call Blocking by the Recipient
- Many individuals and businesses utilize services that block calls from restricted or unknown numbers. If the person you’re calling has enabled this feature, your call will likely be rejected or routed to voicemail regardless of whether or not you used *67.
Caller ID Trapping and Anti-Spoofing
- Some advanced Caller ID trapping services and network security measures can bypass *67. These are typically used by law enforcement agencies or in specific security-related scenarios.
- Furthermore, there are technologies designed to detect and flag number spoofing. While *67 does not technically spoof a number, calls without a Caller ID may trigger these security measures.
Other Factors
- Some older telephone systems or smaller providers might not fully support the *67 feature, but these instances are becoming increasingly rare.
- In some corporate or government environments, calls that are masked by *67 might be routed to an operator or flagged for further examination.
Alternatives to *67
If you find that *67 isn’t working for you, or if you’re looking for more robust options for call privacy, here are some alternatives to consider:
Carrier-Based Number Blocking
- Some mobile carriers offer options to **permanently block your number**, either across all calls or for specific individuals. This often involves modifying your account settings through your carrier’s website or app.
App-Based Privacy Services
- There are numerous **third-party mobile apps** that offer sophisticated call privacy features, including masking your number, using a virtual number, and managing your Caller ID. Be sure to select a reputable app that respects your data privacy.
“Anonymous Call Rejection” or *77
- Remember that *77 is not for masking your number. **Instead it is used to reject calls from people who are blocking their number from being displayed**.
*82 Code
- On the flip side, you can use ***82 to unblock your number** when you call someone who may be using a call rejection feature on their phone and is not receiving calls from unknown numbers.
Disabling Caller ID Through Settings
- On both Android and iPhones, you can disable your Caller ID altogether, which is a different setting than *67.
