When you dial *31# before making a call, it allows you to hide your caller ID, which means that the person receiving the call will not be able to see your phone number displayed on their caller ID. This can be useful in various situations where you may want to keep your number private or maintain anonymity.
By hiding your caller ID, you can protect your privacy and prevent the person you are calling from identifying your number. This can be particularly helpful if you are making a call to an unknown person or a business where you prefer to keep your identity hidden. It can also be useful if you are contacting someone who you do not wish to have your number, such as a telemarketer or an acquaintance with whom you do not want to share your contact information.
When you dial *31#, your phone service provider will intercept the call and prevent your caller ID from being displayed. Instead, the recipient will typically see a message such as “Private Number” or “Unknown Caller” on their screen. This can help maintain your privacy and prevent unwanted calls, especially if you are concerned about your personal information being shared without your consent.
However, it’s important to note that not all phone service providers support the *31# feature. Therefore, it’s advisable to check with your provider to ensure that this option is available to you. Additionally, some individuals may have activated a feature on their phone that blocks calls from private or unknown numbers, in which case they may not answer your call even if you hide your caller ID.
Dialing *31# before making a call allows you to hide your caller ID and maintain your privacy. It can be helpful in various situations where you do not want the recipient to see your phone number. However, it’s important to check with your phone service provider to ensure that this feature is supported, and be aware that some individuals may have call-blocking features activated on their phones.
