This wikiHow teaches you how to make your name and phone number invisible to recipients. Keep in mind that if your caller ID is successfully blocked so the other person can't see it, it's very likely that he won't pick up your call; In addition, many call-screening applications and services that immediately disconnect calls from callers have masked numbers. Blocking your caller ID will not prevent unwanted numbers from calling you.

Step

Method 1 of 2: Using ID Block Code

Step 1. Understand how blocking codes work

If you want to Block caller ID for only one call, add a prefix to the number you want to call so that your caller ID is temporarily blocked. This prefix needs to be included whenever you want to mask caller ID when making a call.

This method will not work if the recipient of the call has an app or service that unblocks caller ID

Step 2. Know your block code

If you have a GSM phone in the United States (for most Androids), use the code #31#, and for other cellular service providers in the United States you can usually use the code *67. The following is a list of other blocking codes that can be used:

  • *67 - United States (except AT&T), Canada (landlines), New Zealand (Vodafone phones)
  • #31# - United States (AT&T phones), Australia (cellular), Albania, Argentina (cellular), Bulgaria (cellular), Denmark, Canada (cellular), France, Germany (some mobile service providers), Greece (cellular), India (only after network lock is unlocked), Israel (mobile), Italy (mobile), Netherlands (KPN phones), South Africa (mobile), Spain (mobile), Sweden, Switzerland (mobile)
  • *31# - Argentina (landlines), Germany, Switzerland (landlines)
  • 1831 - Australia (landline)
  • 3651 - France (landline)
  • *31* - Greece (landlines), Iceland, Netherlands (most mobile service providers), Romania, South Africa (Telkom phones)
  • 133 - Hong Kong
  • *43 - Israel (landline)
  • *67# - Italy (landline)
  • 184 - Japan
  • 0197 - New Zealand (Telecom or Spark mobile)
  • 1167 - Rotary telephone in North America
  • *9# - Nepal (NTC prepaid/postpaid phones only)

Step 5. Type in the phone number

Without pressing the " Call " button, enter all the phone numbers you want to call.

  • Since you'll need to try several different codes, it's a good idea to test first using a friend's number instead of the number you're actually calling.
  • The number to be called must be in the format [code][number], which will look like this: *67(123)456-7890

Step 1. Understand how Google Voice works

Google Voice gives you a new 10-digit phone number; this number is used when you make a call using Google Voice.

  • Using this app won't prevent the recipient from seeing your Google Voice number, but they can't see your real phone number even if they have an unmasked app or service installed.
  • Using Google Voice is a great way to contact people who have an unmasking app or service, without having to show a real phone number.

Step 20. Call using Google Voice

When calling, Google Voice will give you another number to call; between this number and the number your Google Voice account uses, your real number will not appear on the phone of the person you are calling. To make a call, you simply:

  • Tapping the label Calls.
  • Tap the green white keyboard icon in the lower right corner.
  • Press the number you want to call.
  • Tap the white green " Call " button at the bottom of the screen.
  • Wait for a menu containing various numbers to appear.
  • Tap call to call.

Tips

  • Many cellular services provide permanent caller ID blocking facilities. However, usually you will be charged a monthly fee.
  • A temporary block code does not prevent your caller ID from appearing in emergency services (eg ER or police). That way, these emergency services can still see and track your call ID.
  • If you want to make anonymous calls that can't be traced back to you, use a pay phone.

Warning

  • Using a prepaid phone does not guarantee your caller ID is blocked as some companies pass this information on to the recipient.
  • If you want to leave old Google Voice numbers, wait 90 days before installing new ones.
