To block a number from calling, two commonly used "star codes" on many phone networks are *60 and *77. These codes offer different functionalities to help manage unwanted calls.
Understanding Star Codes for Call Blocking
Star codes are special feature codes dialed from your phone that activate or deactivate certain services provided by your network carrier. Their availability and exact functionality can vary, so it's always a good idea to confirm with your specific phone service provider.
Here's a breakdown of the common codes used for blocking calls:
| Star Code | Function | How It Works |
|---|---|---|
| *60 | Call Block / Selective Call Rejection | Dial *60 and follow the voice prompts to add numbers to a rejection list. You can typically block the last incoming number or enter a specific number you wish to block from calling you again. This service is often used to block individual spam or unwanted callers. |
| *77 | Anonymous Call Rejection / Blocked Numbers | When activated, *77 automatically rejects calls from numbers that have withheld their Caller ID or appear as "private," "unknown," or "blocked." This is a useful tool for preventing telemarketers or other callers who intentionally hide their identity. |
How to Use These Codes
- For *60:
- Pick up your phone and dial *60.
- Listen to the voice prompts. You will usually be given options to:
- Add the last number that called you to the block list.
- Enter a specific phone number you wish to block.
- Review or remove numbers from your block list.
- Follow the instructions to complete the process.
- For *77:
- Pick up your phone and dial *77.
- You will typically hear a confirmation that Anonymous Call Rejection has been activated.
- To deactivate it, you usually dial *87.
Important Considerations
- Carrier Specific: While these star codes are widely used, their availability can depend on your specific landline or mobile service provider. Always verify with your carrier if these services are offered and if there are any associated fees.
- Spam vs. Individual Blocking: *60 is more for individual, specific number blocking, while *77 focuses on blocking anonymous or unidentified callers.
- Alternative Methods: If these codes don't work or aren't offered by your provider, many modern smartphones (iPhone, Android) offer built-in features to block numbers directly from your call history or contacts list. There are also third-party apps designed to identify and block spam calls.
