Reverse Search Phone Numbers – A Manual Approach

It never crossed my mind that in my life I would have to do reverse search phone numbers but due to a special circumstance I was forced to do it to help a family member. When I was looking for a way to do it, I did a lot of research in the internet and I noticed something interesting. Read on…

Actually, reverse search phone numbers can be done by looking closer at the phone number itself. Ok, let’s take a closer look into this example. Now, you have a telephone number 123-456-7890, that’s a common phone number format defined by NANPA (North American Numbering Plan Administration) and it is called NANP (North American Numbering Plan). NANP actually is being used in 19 countries in North America including United States. When you see a phone number in that particular format then you should know that is an NANP.

Way back, when NANPA issued the phone numbers, they need to come up with a certain rule and structure to make sense of the phone numbers issued. See illustration below

Part A (e.g. 123), the first three digits is area code. Part B (e.g. 456), the second three digit is office code or cellular phone code. Part C (e.g. 789), the last 4 digits is individual number. By looking at the facts here at least you can narrow down your search using 2 things:

1. Part A will give you good idea about from what area that call is coming from

2. Part B will give you some ideas about from which carrier or cellular provider the call is being made

The only thing we cannot be sure about is Part C, so this way, we can do a very fast general reverse search phone numbers just by looking at the phone numbers. Of course, it’s a very manual and general way to do reverse telephone lookup, you can’t get any specifics about the person calling you, but there are always other free and paid alternatives, such as free reverse directory phone number and reverse phone number lookup directory, available today.
