The Secrets of Staggering, Part 2: Staggering Methodology

At one time many years ago, it was normal for all license plates in a given state to expire at the same time of the year...either at the end of December, or at the end of a two- to four-month grace period extending into the new year. As registration figures exploded, so did long waits and logistical difficulties at renewal time...so a widespread transition to staggered registration systems emerged.

How did it happen, though? When staggered registration began, how did states, provinces, districts, and territories go about setting it up? As it turns out, a vast and varied array of methodology was involved.

Methodology of assigning registration months

Initial staggering of pre-existing registrations (left); current staggering of new registrations (right)

[Initial staggering methodology - U.S.] [Subsequent staggering methodology - U.S.]

    = Staggered by registrant's name or initial as criteria.
    = Staggered by registrant's birth month.
    = Staggered by registrant's plate number.
    = Grandfathering; existing registrations not staggered.
    = No special methodology.

[Initial staggering methodology - Canada] [Subsequent staggering methodology - Canada]

Adoption of staggered registration by decade

Delaware pioneered staggering with a quarterly system in 1941, and in 1946 Wisconsin became the first state to stagger expirations between all twelve months of the year. A trickle turned into an avalanche when the 1960s drew to a close, and by 1977 over half the states in the U.S. had switched to staggered registration systems. Canada was a bit slower to embrace the trend, with Saskatchewan becoming the first province to do so in the same year. By the end of the 1990s the practice was universal, with the last holdouts being Manitoba (switching in 1995) and Georgia (1997).

[Era of staggering - U.S.] [Era of staggering - Canada]

    = 1940-49 (3)
    = 1950-59 (2)
    = 1960-69 (3)
    = 1970-79 (30)
    = 1980-89 (18)
    = 1990-99 (7)


Here is every jurisdiction in the U.S. and Canada that uses staggered registration, listed in the order the methodologies were adopted (the letters n/p indicate a month reserved for non-passenger types).

1942

Delaware

> Apparently assigned by estimated distributions:

1/4 1/4 1/4 1/4
9-30 42 12-3142 3-31 43 6-30 43

> No special methodology for new registrations. (Porcelain baseplates were introduced to new registrants eight months early and a half-year registration option was available, so ultra-rare "41" tabs exist.)


1946

Wisconsin

45 (expiring 12/45)

> Assigned by estimated distributions:

30000 10000 60000 60000 60000 60000 60000 60000 60000 60000 60000 rest

1949

Missouri

48 (expiring 12/48)

1/12 1/12 1/12 1/12 1/12 1/12 1/12 1/12 1/12 1/12 1/12 1/12
Jun49 Jul49 Aug49 Sep49 Oct49 Nov49 Dec49 Jan50 Feb50 Mar50 Apr50 May50

There is some speculation that initial staggering may have been done with a narrow JAN-MAR spread; however, the initial serial format on the 1949 base was divided into equal blocks for all 12 months.

> No special methodology for new registrations.


1950

Oregon

49 (expiring 12/49)

> Staggered by outgoing 1949 plate number, using complicated blocks of assignments:

1956

New Jersey

> Same methodology applied in reverse to new registrations, so that last digit served as a month code (through 1986).


Massachusetts

> Staggered by last digit or character of plate number. Biennial registration was established at the same time:

West Virginia

70 (expiring 1/70-12/70)

> Staggered by outgoing 1970 plate number (leading digits shown). Outgoing plate was replaced gradually according to the same schedule:

There is also speculation that all 1970 plates were replaced in June instead of being gradually phased out throughout the year. However, there is evidence that the 1970-dated plate was used for less than a full year: The highest known number is 591-040, whereas the 1969 plate has been confirmed as high as 624-450. Hopefully, some additional information will surface that would lay these mysteries to rest.
