National Do Not Call Registry

The National Do Not Call Registry gives you a choice about whether to receive telemarketing calls at home. Most telemarketers should not call your number once it has been on the registry for 31 days. If they do, you can file a complaint at www.donotcall.gov. You can register your home or mobile phone for free.

Reverse Phone Lookup

Being able to do a reverse phone lookup has made things alot better for all of us. The fact that you can  trace someone from their phone number has stopped alot of the unwanted phone calls. With the reverse phone lookup system you can find out who these unwanted phone calls are coming from if you have caller id, something almost everyone has these days.

call from an unidentified number

If you get a call from an unidentified number, it can be completely innocent. Not the least of these cases is one where the caller is simply an old friend or relative that just got a new cellphone and they are calling to give you their new phone number. However, more often than not, this will not be the first thing crossing the mind of someone receiving that kind of phone call.
