It is a number used by telemarketers and other companies that don’t want to reveal their true identity or location.

2. Again, it spells RES-TRI-CTED on your telephone keypad!


What happens when you call the number?

Interestingly, when you call the number back, you will get the same answer again and again — your call cannot be completed as dialed. Calls from 737 area code can’t be dialed because the code doesn’t exist. It can be frightening but it is just an internet gimmick. So, the next time you get a call from the number, don’t spend time finding out where it came from. 


You might have one question in your mind – where is the 874 area code from? It is supposed to be from Illinois but since it is a spam number, it can literally be from anywhere. 


How can I block the number?

A simple answer to this question is – you block it from your phone. When you get a call next time, tap on the ‘i’ icon and go to the very end and click ‘block this caller.’ The number won’t bother you ever again.

The process is quite simple and only takes a few minutes. You need to register your number in the program by either calling 1-888-382-1222 or visiting the donotcall.gov. You will receive a confirmation email. You need to click on the link within 72 hours upon receiving it to successfully register.

Will the calls stop immediately?

The unwanted calls don’t stop immediately, but once you are in the Registry for over 31 days, they will completely stop. You might get a call from a new spam number but that would happen only once. 


However, if you have signed up to receive calls from a particular company, you will get calls. If you don’t want to receive calls from them, simply ask them to respect your privacy. 


Whenever you get a spam call, let it ring out because if you press any number on the dialer, the phone number might get access to your phone. If you continue getting calls from a particular number despite blocking it, contact your service provider to block it from their end.
