What are star codes?

Answer 1

It's important to note, that while these codes are generally accurate across phone providers, there may be some differences.

Anonymous Call Rejection: *77 to enable, *87 to disable

Call Curfew: *78

Call Forwarding: *72 / *73

Call Forwarding - Busy: *90 / *91

Call Forwarding - Don't Answer: *92 / *93

Call Forwarding - Selective: *63 / *83

Call Rejection: *60 / *80

Call Trace: *57

Call Waiting - Deactivation: *70

Caller ID Block Per Call: *67 / *82

Caller ID with Privacy Plus: *78 / *78

Continuous Redial: *66 / *86

Dial Call Waiting: *97

Dial Lock: *78 / *78

Do Not Disturb: *78 / *78

Last Call Return: *69 / *89

No Solicitation: *78 / *78

Priority Call: *61 / *81

Remote Access Forwarding: *78 / *78

Security Screen: *78 / *78

Selective Call Rejection: *60 / *80

Selective Call Waiting *78 / *78

*78 is a short cut to the Qwest Update Center, that's why 7 codes are to them. That's probably going to be different between the different phone companies
