What is a 419 scam?

419 scams

Advance fee fraud spam such as the Nigerian "419" scam may be sent by a single individual from a cyber cafe in a developing country. Organized "spam gangs" operating from Russia or eastern Europe share many features in common with other forms of organized crime, including turf battles and revenge killings

An advance-fee fraud is a confidence trick in which the target is persuaded to advance sums of money in the hope of realizing a significantly larger gain. Among the variations on this type of scam, are the Nigerian Letter (also called the 419 fraud, Nigerian scam, Nigerian bank scam, or Nigerian money offer), the Spanish Prisoner, the Black money scam as well as Russian/Ukrainian scam (also extremely widespread, though far less popular than the former). Both the so-called Russian and Nigerian scams stand for wholly dissimilar organised crime traditions, they therefore tend to use altogether different breeds of approaches.

The 419 scam originated in the early 1980s as the oil-based Nigerian economy declined. Several unemployed university students first used this scam as a means of manipulating business visitors interested in shady deals in the Nigerian oil sector before targeting businessmen in the west, and later the wider population. Scammers in the early-to-mid 1990s targeted companies, sending scam messages via letter, fax, or Telex. The spread of email and easy access to email-harvesting software significantly lowered the cost of sending scam letters by utilizing the Internet. In the 2000s, the 419 scam has spurred imitations from other locations in Africa, Asia and Eastern Europe, and, more recently, from North America, Western Europe (mainly UK), and Australia.

The number "419" refers to the article of the Nigerian Criminal Code (part of Chapter 38: "Obtaining Property by false pretences; Cheating") dealing with fraud. The American Dialect Society has traced the term "419 fraud" back to 1992.

The advance-fee fraud is similar to a much older scam known as the Spanish Prisoner scam in which the trickster would tell the scam victim that a (fictitious) rich prisoner had promised to share (non-existent) treasure with the victim if the latter would send money to bribe the prison guards.
