69 is a feature offered by many telephone service providers that allows you to call the last number that called you. This service is typically activated by dialing 69 on your phone.

How it Works:

• When you receive an unwanted call, you can immediately dial *69 to initiate a call back to the last number that dialed your line.
• This feature is helpful for identifying the caller, especially if you missed the call or if the number is unknown.

Important Notes:

• The availability and functionality of *69 may vary depending on your service provider.
• There is usually a small fee associated with using *69.
• Be aware that *69 may not always work correctly, and it's not a foolproof method for identifying or blocking unwanted calls.

Alternatives:

If *69 isn't available or effective, consider these alternatives:

• Caller ID: This feature displays the number of the incoming call on your phone screen.
• Call Blocking: Many phones and service providers offer call blocking features that allow you to block specific numbers from calling you.
• Mobile Apps: There are various mobile apps that can help you identify unknown callers and block unwanted calls.
