MM series of older car registration numbers.

Registration letters >> MM series
This page lists registration number codes from the MM series, a series allocated to the London area. Also included, where known, are the date periods that these car registration numbers were used in. The data covers the period of 1900 through to 1972, so registrations seen on later cars wouldn't necessarily be included in this information.

Interpreting a car's registration number.

The majority of post-war car numbers incorporate a three letter code - where this is the case, letters 2 and 3 signify the location code. So, for instance, a car with the registration number 638 GMM or TMM 512D would be a London-issued number. A car with just two letters, ie MM, would also be from this area. Listed below are the known MM series registrations, with added information (where available) describing when each series was first used, and in a few cases, when it came to an end. Some letter codes were used for more than one period during the 20th Century. This information can be invaluable when trying to date vehicles seen in old photographs, or in old films for instance.
Also if your car has lost it's original registration, perhaps sold off by a previous owner as a "cherished" number, this information will help you find a suitable replacement, or at least identify which series would be suitable, based on the age of your car and where it was first registered.
