Advance Fee Fraud (419 Scam)
The 'Spanish Prisoner' letter, offering a share of a hidden fortune in exchange for money to free a jailed nobleman, was documented in Britain and the US by the 1890s (New York Times, 1898); the modern '419' form took shape in Lagos, Nigeria in the 1980s, spreading by post and fax.
The method goes back at least to the 'Spanish Prisoner' letters of the 19th century, in which a writer claimed a wealthy man was jailed in Spain and asked for money to free him in exchange for a share of his fortune; the New York Times reported on such letters in 1898. The modern '419' name comes from Section 419 of Nigeria's Criminal Code, which covers obtaining property by false pretences, after the scheme spread from Nigeria by post and fax in the 1980s. It moved to email in the 1990s with the familiar 'foreign prince' and 'inheritance' messages, and is now run worldwide through lottery, loan, job, inheritance and recovery-scam variants. It also overlaps with romance scams, where a fake partner asks for fees to release money or travel.
The victim is told a large sum is waiting for them, such as an inheritance, lottery win, business deal or loan, but must first pay a small fee, tax or bribe to release it. Each payment is followed by a new obstacle and a new fee, so the victim keeps paying in hope of the big payout. Fake official documents, bank letters and stamps are used to make the story believable, and the promised money never arrives.
It costs almost nothing: a letter, then an email address, and now a WhatsApp account, sent to millions in the hope of a few replies. Response rates are tiny but the take per victim is large, and Ultrascan estimated global losses at $12.7 billion in 2013; the same networks now run romance, lottery and job variants. Prosecution is rare because senders are abroad and victims are ashamed, though Nigeria's EFCC, created in 2003, has secured thousands of convictions.
Ultrascan AGI estimated worldwide 419 losses at $12.7 billion in 2013, the last comprehensive estimate; the FBI's 2025 report logged $194 million in lottery, sweepstakes and inheritance losses in the US alone. The biggest single case was Emmanuel Nwude's $242 million fraud on Brazil's Banco Noroeste (1995-1998), which helped bring the bank down (BBC, 2005). Victims have gone bankrupt and some have killed: a Czech retiree shot a Nigerian consular official in Prague in 2003 after losing his savings (BBC, Feb 2003).
