The M600 is a secret administrative number for the M6 Toll, used because "M6 Toll" doesn't fit the alpha-numeric pattern for road numbers. All signs refer to the road as M6 Toll, since that is its true designation; this number exists primarily to allow the road to be referenced on computer systems and databases maintained by highway authorities, which were produced before the number "M6 Toll" existed and which allow only road numbers in conventional formats. As a result this number is largely unknown to the public.
The road originally had a working number of A446(M), and when consideration was being given to allocating a permanent number, M600 was one of the possible options - however, it was not selected.
