The M600 is signed throughout as M6 Toll, which is the road's legal number. It is a secret administrative number, used because M6 Toll doesn't fit the alpha-numeric pattern for road numbers. The Birmingham Northern Relief Road originally had the A446(M) working number, however, upon opening, it became the M600.
