How to Fake a Card Number with a Bit of Flair

In a recent correspondence, Gary Calder from Chandler’s Ford in Hampshire offered advice to readers interested in pranking bank-card scammers, as outlined in an August 29 article titled ‘I’ve £80k in the account, here’s my pin’: turning the tables on the scammers.’ Calder suggested using a known issuer identification number (the first six to eight digits) to add realism to a fabricated card number, ensuring that the final digit satisfies the Luhn algorithm, which is used to catch errors in digit entry.

For added creativity, he recommended using notable UK postcodes, such as SW1A 2AA or 2AB for 10 and 11 Downing Street, SW1A 2JL for New Scotland Yard, or SL4 1NJ for Windsor Castle.

The piece also notes that The Guardian invites readers to email their opinions on articles for potential publication in their letters section.
