Ever receive a call from an unknown number and wondered how callers mask their numbers? This tactic does come in handy for certain instances. If you’ve ever wanted to anonymously call back a mysterious number or track down a contact who is avoiding your calls, these are just two examples when making your number unknown might be useful.

Fortunately, you don’t have to buy a burner phone or invest in complicated technology to make a private call. With most telecom carriers, it’s as easy as entering a few digits. Some phones even have built-in privacy settings that make your number unknown with a tap.

Here’s what you need to know to make a private call from a landline or smartphone.

How to make a private call

Most telecom providers use a universal prefix, *67, to temporarily make your number unknown. To make a private call, you enter *67 before the number you’re calling to block your identity on caller ID. This procedure works on most landlines and mobile phones, although some carriers may have different codes.

AT&T, for example, uses #31#. To make a private call with AT&T, enter #31# before dialing the number to block your ID. In some markets, *67 may be available with AT&T. If you’re not sure which prefix works in your area, try making a private call to a friend using both #31# and *67 to see which one makes your number unknown.

If you want your number unknown for all your outgoing calls, you may change the privacy settings through your telecom carrier’s app or website. Both Verizon and Sprint let you turn off caller ID simply by changing your account settings.

If you use Sprint:

  • Access your “My Sprint” account through the website or app
  • Select the device you want to have an unknown number
  • Select “Change my services” and toggle the “block caller ID” option

If you use Verizon:

  • Open the “My Verizon” app
  • Tap “Devices” and select the device you want to make private
  • Tap “Controls” and select “Adjust service blocks”
  • Toggle “Block Caller ID”

You can also make your number unknown through the “Blocks” page in your “My Verizon” account on the Verizon website.

If you activate private calling through your provider app or website, you can turn it off on a call-by-call basis by entering *82 before you make a call.

One thing to remember about making private calls: The technology doesn’t work with toll-free numbers. If the number you’re calling has a toll-free prefix (800, 833, 844, 855, 866, 877 and 888), you won’t be able to make your number unknown.

How do I protect my communication privacy?

If you’re concerned about communication privacy, you’re not alone. In a recent Pew Research survey, 74% of Americans said it is very important for them to be in control over who can get their personal information. Although you can’t protect all your publicly available data, you can take steps to keep your communications private.

  • Always lock your phone and other devices. Even if your phone has a biometric (face or fingerprint) lock, use a strong PIN or passcode along with it. If available, enable your phone’s remote tracking and locking features. Should your phone ever get lost or stolen, you’re better protected against a data breach.
  • Don’t answer calls from blocked or unknown numbers. Phone scams are on the rise; the U.S. is on pace to get 60 billion robocalls this year. Ignoring or rejecting unknown calls is the best way to protect yourself. If you’re not sure whether the number is legitimate, use a reverse phone lookup tool to try to identify the caller before answering your phone.
  • Be cautious about emails from unknown senders. Phishing cost U.S. victims $48 million in 2018 alone. Learn how to better educate yourself against a phishing attack and avoid opening any suspicious-looking emails. You can use a reputable reverse email tool before deciding how to handle emails that look legitimate but whose contents seem suspicious or “off.”
  • Learn how to make private calls. Blocking your caller ID is more than just a convenience when you’re trying to track down a shady contact or see who’s behind a suspicious call—it can be an essential safety tool. Make your number unknown before calling online sellers or making contact for the first time with an online date.
