In the era of smartphones and digital communication, landlines may seem like a relic of the past. However, many people still rely on these traditional phone systems for various reasons, including reliability, security, and simplicity. One often-overlooked aspect of landlines is the range of special codes and features that can be accessed using specific sequences of numbers. Among these, 77 is a particularly intriguing code that has sparked curiosity among many landline users. So, what does 77 do on a landline?
The Origins of *77: A Brief History
To understand the purpose of *77, it’s essential to delve into its history. The origins of this code date back to the early days of telephone technology, when call waiting and call forwarding were still in their infancy. In the 1950s and 1960s, telephone companies began introducing these features to enhance the functionality of their systems.
77, in particular, was designed as a quick and convenient way to activate call tracing, a feature that allowed users to identify the phone number of an incoming call. This was especially useful in situations where callers were being harassed or threatened. By dialing 77, users could automatically trace the last call they received and report the number to the authorities if necessary.
How *77 Works on a Landline
So, how does *77 work on a landline? The process is relatively simple:
When you dial *77 on your landline, you are activating the call tracing feature. This feature uses a internal system within the telephone exchange to capture the phone number of the last incoming call. The phone number is then stored in a database, which can be accessed by the telephone company or law enforcement agencies upon request.
Here’s an important note: 77 only works for the last incoming call. If you receive multiple calls after activating 77, the system will only capture the phone number of the most recent call.
The Benefits of *77 on a Landline
The benefits of *77 on a landline are twofold:
Safety and Security
*77 provides an added layer of security for landline users, particularly in situations where they feel threatened or harassed. By being able to trace the phone number of an incoming call, users can report the number to the authorities and take necessary action to protect themselves.
Convenience
*77 is a quick and easy way to access call tracing, eliminating the need to contact the telephone company or wait for assistance. This feature is especially useful in emergency situations where time is of the essence.
Common Misconceptions About *77
Despite its benefits, *77 has been surrounded by misconceptions and myths. Here are a few common ones:
*77 is a Universal Code
One common misconception is that 77 is a universal code that works on all phones, including mobile devices. However, this is not the case. 77 is specifically designed for landlines and may not work on mobile phones or VoIP (Voice over Internet Protocol) systems.
*77 is a Blocking Feature
Another misconception is that 77 blocks incoming calls. This is not true. 77 only traces the phone number of the last incoming call; it does not block or restrict incoming calls in any way.
Activating *77: Carrier-Specific Details
While *77 is a standard code, its activation process may vary depending on your telephone service provider. Here are some carrier-specific details to keep in mind:
| Carrier | Activation Process |
|---|---|
| AT&T | Dial *77 immediately after hanging up on the unwanted call |
| Verizon | Dial *77, then dial 1 to confirm the trace |
| CenturyLink | Dial *77, then dial 1 to confirm the trace, followed by 1164 to hear the traced number |
Please note that these details may be subject to change, and it’s always a good idea to consult with your telephone service provider for specific instructions.

What is the *77 code, and why was it created?
The *77 code is a special feature code that was introduced by telephone companies in the United States in the mid-20th century. It was primarily designed to assist phone users in blocking anonymous calls from telemarketers, prank callers, and other unwanted callers. The code was created to provide a sense of security and privacy for landline phone users, especially during a time when cold calling and telemarketing were becoming increasingly prevalent.
The *77 code worked by allowing users to activate a feature that would block all incoming calls from private or unknown numbers. This feature was often referred to as “anonymous call rejection” or “private call rejection.” Once the feature was activated, calls from numbers that were blocked or restricted would not ring through to the user’s phone. Instead, the caller would receive a message stating that the call was not accepted.
How do I activate the *77 code on my landline phone?
To activate the 77 code on your landline phone, you typically need to dial 77 followed by the # key. This will activate the anonymous call rejection feature on your phone line. Some phone companies may have slightly different instructions, so it’s always a good idea to check with your service provider to confirm their specific activation process.
Once you’ve activated the feature, you’ll typically hear a confirmation tone or a recorded message stating that the feature has been turned on. From that point forward, calls from private or unknown numbers will be blocked, and you’ll no longer receive unwanted calls from telemarketers, prank callers, or other unwanted callers.
Can I use the *77 code on my cell phone?
Unfortunately, the 77 code is only compatible with landline phones and is not supported by most cell phone networks. This is because cell phones use a different technology and infrastructure than traditional landline phones, and the 77 code is not programmed to work with mobile devices.
If you’re receiving unwanted calls on your cell phone, there are other methods you can use to block them. For example, you can add unwanted numbers to your phone’s block list, use a third-party call-blocking app, or register on the National Do Not Call Registry. These methods can help reduce the number of unwanted calls you receive on your cell phone.
Does the *77 code block all unwanted calls?
While the 77 code can be an effective way to block many unwanted calls, it’s not foolproof and may not block all unwanted calls. Some callers may use techniques to circumvent the blocking feature, such as using a calling card or a payphone. Additionally, some phone companies may not support the 77 code, or may have different instructions for activating the feature.
It’s also important to note that the 77 code only blocks calls from private or unknown numbers. If a caller has a legitimate reason for calling you and is willing to disclose their phone number, the 77 code will not block their call. This means that you may still receive unwanted calls from legitimate businesses or individuals who are not trying to hide their phone number.
How long does the *77 code remain active?
The 77 code typically remains active until you deactivate it by dialing 87 followed by the # key. Once you’ve deactivated the feature, calls from private or unknown numbers will no longer be blocked, and you’ll start receiving calls from these numbers again.
It’s worth noting that some phone companies may have slightly different instructions for deactivating the *77 code, so it’s always a good idea to check with your service provider to confirm their specific deactivation process.
Is the *77 code still supported by phone companies?
While the 77 code was widely supported by phone companies in the past, it’s no longer a standard feature offered by many service providers. In recent years, phone companies have introduced new features and technologies to help block unwanted calls, rendering the 77 code less necessary.
Some phone companies may still support the 77 code as a legacy feature, but it’s not as widely available as it once was. If you’re unsure whether your phone company supports the 77 code, it’s best to check with their customer service department to confirm.
What are some alternative methods for blocking unwanted calls?
If the *77 code is not available or not effective in blocking unwanted calls, there are several alternative methods you can use. One option is to register on the National Do Not Call Registry, which prohibits telemarketers from calling your number. You can also use call-blocking apps or services, such as Nomorobo or Hiya, which can block unwanted calls and texts.
Another option is to use a digital voicemail service, which can screen calls and block unwanted callers. Some phone companies also offer their own call-blocking features, such as Verizon’s Caller Name ID or AT&T’s Call Protect. It’s worth exploring these options to find the one that works best for you.
