Client Code Decoder

Unscramble a client code to reveal the original date and initials

How the Scrambling Works

Format: Y[F]Y[L]YY-MM-D[F]D

Key:

  • F = First letter of First name
  • L = Last letter of Last name

Example: Margaret Thompson on 2026-03-23 becomes 2M0N26-03-2M

  • 2 = First digit of year (2)
  • M = First letter of FIRST name - Margaret (M)
  • 0 = Second digit of year (0)
  • N = Last letter of LAST name - Thompson (N)
  • 26 = Last digits of year (26)
  • -03- = Month (03)
  • 2 = First digit of day (2)
  • M = First letter of FIRST name (M)
