I worked on a DVLA VED system a year ago, it's a check digit derived from the registration number.

Check digit is just a term used for any alphanumeric character derived from others by way of an algorithm. It's there to counter counterfeiting. A counterfeiter without the algorithm couldn't know what character to put there. And so someone running the reg no through a program that calculates the check digit can check the authenticity of the tax disc.

the last number/character in a Vat number does the same job
