On a telephone, dialing *77 (star 77) typically activates or deactivates Anonymous Call Block. This feature allows you to block calls from private or blocked numbers.
How it works:
- Activation: When you dial *77, your phone service provider will usually play a confirmation message or tone, indicating that Anonymous Call Block is now active.
- Blocking Anonymous Calls: With Anonymous Call Block activated, anyone calling you with a blocked or private number will be prevented from reaching you. They will usually hear a message stating that you don't accept calls from blocked numbers and prompting them to unblock their number and try again.
- Deactivation: To deactivate Anonymous Call Block, you will typically dial *87. This will allow you to receive calls from blocked or private numbers again. (Note: Some providers may use a different code; check with your service provider for confirmation.)
Alternatives on Older Phones:
On older rotary or pulse-dialing phones, you might need to dial 1177 to activate the feature.
Important Considerations:
- Service Availability: Anonymous Call Block is not available in all areas or from all phone service providers.
- Cost: Some providers may charge a fee for this service.
- Effectiveness: While it blocks calls with explicitly blocked numbers, it won't stop all unwanted calls (e.g., those from unblocked numbers).
Before using *77, contact your phone service provider to confirm the specific features, codes, and any associated costs.
