Anyone know what a Code 16 is?

Apart from the normal rubbish which this e-mail is trying to communicate, the only thing which is unusual, is the "Code 16" in the subject line. Could it be these people are tracking their ads?

Dear Friend.
I am Mr. Richard Wilford, the only son of late Chief John Wilford from Sierra-Leone. I got your contact from the Internet through My Search to help me and need assistance from you.,i am sorry to inconvinience you,But your help is Needed in our life.
My sources of your contact gave me encouragement and confidence to write you. I am writing you in absolute confidence primarily to seek for your assistance to transfer our cash of (Fifty-Five Million United Stated Dollars) (55,000,000.00) now in the custody of the Security and trust Company In Europe to your private account pending our arrival to your country.

SOURCES OF THE FUND
My late father, chief John Richard Wilford, a native of Mende District in the northern province of Sierra-Leone, he was the general manager of Sierra-Leone
Mining Co-operation (S.L.M.C) Freetown. According to my father, this money was the income accrued from mining co-operation overdraft and minor sales.
Before the peace of the civil war between the rebel forces of Major Paul
Korormah and the combined forces of ECOMOG peace keeping operation that almost destroyed my country, following the forceful removal of the civilian elected president Ahmed Tejan Kabbah from power by the rebels.

My father had already made arrangement for his family, my mother, my little sister and myself to be evacuated to Spain, with our personal effort and the box containing the money. My father deposited the box in a private security company here in Spain for the safe custody until after the war when he will join us. During the war in my country, and following the! Indiscriminate searching of the public and government properties by the rebels forces, the Sierra-Leone mining corporation. Was one of the targets looted and destroyed. My father including other top government functionaries were attacked and killed by the rebels because of the relationship with the civilian president Ahmed Tejan Kabbah.

As a result of my father's death, our hope of survival was shattered. The
untimely deaths caused my mother heart failure and other related complications of which she later died in hospital after we spent a lot of money on her. Now, my 16 years old sister and myself are alone in this strange country suffering without any care or help. Without any relation, we are now like refugees and orphans In The street,We dont even have a home,we only survive By the food given to us by the Cruz roja of spain,Meaning Red cross..
Our only hope now is in you and the box deposited in a Security Company.
To this effect, I humbly solicit for your assistance in the following ways.
To assist me claim this box from Security Company as co-beneficiary. To transfer this money in your name and to your country and to make good arrangement for a joint business investment on our behalf in your country, and you will be the caretaker, and also to secure a college for my little sister and myself in your country to further our education. And to make arrangement for our traveling with you to your country after you have transferred this fund. Most importantly, the security company officials do not know the exact content of the box because it was declared as family valuables. The whole document issued after deposit is in my custody. For your assistance, I have conceded 45% of the money to your efforts assistance. Please reply at richard1wilford@yahoo.com
