Numbers stations on the short wave bands

My first encounter with a numbers station was many moons ago while I was tuning across the short wave bands on a very old radio. I came across an unidentified station where a woman was reading out a string of numbers in German. Needless to say, I had no idea at the time what it meant or what its purpose was.

This video written, researched and presented by Paul Shillito on his Curious Droid YouTube channel explains what numbers stations were and what they were used for.
