The easiest and most effective way to discover anyone is by using their Social Security Number (SSN) – People search by SSN. Being connected with birth and death, financial, student or university, driver's license, vehicle registration, and many other records, for people in the USA, these digits are an unofficial national ID. Because of this, searching for a person using their SSN is quick.

Find out what you find when you put the number into a people search by SSN search engine, as a start. You never know. A lot of the time, this will not work, but it only takes a second, so it is worth a shot. To make sure that the numbers are all that is searched for, and in the right order, make sure you put the number in quotes and do not use any dashes (e.g. "123 45 6789") to find people by SSN.

Because SSNs are so connected with into people's lives, and because identity theft is such a worry, most of the ways to search for someone using their SSN are only available to creditors and pros. You have most probably heard of "skip tracing," which is the term used by pros when searching for a person. Most skip traces are done using SSNs, since to find people by SSN is the easiest way to find a person down.

You do need a license (or someone with one) to find a person's info using their SSN, but that someone doesn't have to be a private detective. A paid search through a licensed firm on the 'Net will cost you much less than a private eye and will get you the info you need to get started on the legwork yourself. There usually is not much, though.

A person's SSN ties them into employment, tax, driver's license, banking, credit, and Social Security records. So this single number, a U.S. Citizen's unofficial national ID number, can be used to find just about anyone in the States. Using the "header" info your 'Net firm gets for you, which comes from the person's credit bureau file, you'll have their current/last-known address, telephone number, and possibly their employer too by searching people by SSN.

The "headers" from someone's consumer credit files is pretty much all that is needed, since these contain employers, last-known/previous and current mailing addresses, phone numbers, cities of residence, etc. The information in these headers can find who you're looking for ninety percent of the time when you run a people search by SSN. No muss, no fuss.A good skip tracer can run several of these files a day, locating two or three dozen people in a day's work. One or two phone calls is generally all that is needed to verify the data.

As you can see, people search by SSN is the quickest way to find people!
