How Do You Block A Phone Number

Knowing how do you block a phone number will prevent the party you are calling from knowing exactly what number they are receiving the call from. Simply by entering a numerical code, you can prevent your number from appearing on the recipient’s caller ID. Properly utilizing the call blocking services available on your phone will allow you to successfully do so.

What you'll need:

• Landline or cell phone
• Computer with internet access or telephone book

1. Visit the website of your phone service provider. The website should give you detailed information on how to block your number for your specific provider. If you are an unable to access the internet, your white page directory should provide you with helpful information as well.
2. Enter the universal call block numerical code, "*67", prior to entering the telephone number of the party you plan to block your phone number from. However, this temporary method will require you to enter "*67" before placing each call in order to be successful.
3. Add the line-blocking option to your existing service. You can also purchase a complete line-block on your telephone if you would like your phone numbered blocked for all of your calls. How much this service costs will vary widely from provider to provider and some states don't even allow the service. You will need to contact your phone service provider for further details.

Tips:

Keep in mind, when you block your phone number from being displayed on the recipient’s caller ID, your name will also be blocked. Generally, the recipient’s caller ID will read "private," "caller unknown" or remain blank.

According to federal law, telemarketers have to display their phone numbers.

Check with your state to find out their specific laws related to phone number blocking.
