what is the significance of # and * buttons on telephone keypad?

Answer 1

These are basically auxiliary keys that have different functions on different telephone systems. For example, with US telephone systems...these keys are used to activate or deactivate calling features. *67 for example blocks your caller ID information. #70 would deactivate call-waiting, he list goes on. They also have different functions depending who you call. Most places that want you to enter numbers want you to hit # after the number...most voice mail boxes let you acccess them by pressing *.

They're important keys in a way. They allow the phone system or whatever system you're calling use these non-numbered keys as a less confusing way of having you enter options. For the phone systems, they usually designate to the central office that you're not dialing a number, but using a feature. But the use varies phone system to phone system as well as call-to-call.

Answer 2

The * and # keys are mainly like "service" keys. Services like *67 and the ability to receive information from the service provider. I know in some countries that have prepaid cell phone lines, either the # or * followed by a number will retrieve your balance. But on house phones they are more for services.

Answer 3

Some phone companies have it set up so that a radio station to call them you just push # and their call numbers or station letter to dial direct to them without keying in their phone number. On some answering machines the * will get you to the main menu.

Answer 4

They have their purposes. They are used to write specific codes to retrieve specific information either regarding the use of your phone or particular technical details etc.
