1916 Truck

Plates were black on orange painted steel.  To the left side of the serial number PENNA embossed over embossed keystone. Maker's number was stamped into the keystone.  1916 embossed below keystone.  An aluminum keystone was only used if the plate was transferred to another vehicle.  On the far left were 1 to 5 stars arranged vertically indicating the weight rating.  Issued in pairs.  Manufacturer was Brilliant Manufacturing Co., Phila., PA. 

It appears that truck and solid rubber tire vehicles plates were generally in the 20000 to 29999 range, however, truck plates outside of this series are known.  Nominal measurements are considered 6" by 16", actual measurement is 6⅛" by 16⅛".

1917 Truck

Plates were white on brown painted steel.  To the left side of the serial number PENNA or PA embossed over embossed keystone. Maker's number was stamped into the keystone.  1917 or 17 embossed below keystone.  PENNA & 1917 were used on lower number plates, while PA & 17 were used on higher plates.  An aluminum keystone was only used if the plate was transferred to another vehicle.  The S-prefix stood for solid-tired motor vehicle.  Weight classes were listed as: First Class to Fifth Class as described below.  On the far left were 1 to 5 stars arranged vertically indicating the weight rating.  Issued in pairs.  Plates were made in state prison system.  Nominal measurements are considered 6" by 14" and 6" by 16", actual measurement of the larger plate is 6⅛" by 16⅛".  Measurements of the size referred to as 6" by 14" need to be verified.

• First Class, 1 star, S1 to S1999, and S15000 to S15199

• Second Class, 2 stars, S2000 to S4499, and S15200 to S15999, and S30046 to S20048, and S20050 to S20074, and S20200 to S20599

• Third Class, 3 stars, S4500 to S10499, and S16000 to S19374, and S19500 to S19599

• Fourth Class, 4 stars, S10500 to S12499, and S14400 to S14499, and S19375 to S19499, and S19600 to S19623, and S21000 to S21099

• Fifth Class, 5 stars, S12500 to S14399, and S19625 to S19649, and S19735 to S19742

Not all class blocks were issued in their entirety, and not all stars and serial numbers were issued uniformly.  If classes ran out of numbers some additional groupings were established.

1923 Truck (Commercial)

Yellow on dark blue, legend, all embossed, PENNA COMMERCIAL 1923 along bottom.  See paragraph below on plate size.  The connection between plate serial number and weight class is related to the first digit in the serial number. 

The serial number can be as short as three digits with or without separation, or or if longer, have 1 to 3 digits in the first grouping, then a dash, then the second grouping of 3 digits.

All plates were believed to be 6"  by 16" regardless of the length of the serial number; however Rob Baran, in his research, has noted 2 sizes.  Most plates are 6"  by 16"; however, two plates, 65-188 and another, actually measure 6"  by 15".  The 15-inch plates have the left side of the plate trimmed, and the beveled edge removed.  He also notes that the positioning of the holes and the slots are reversed on the short plates.  This information came from Rob Baran's article, Pennsylvania Commercial Plates 1920-1923 in February 2019 issue of Plates Magazine.

1931 Mystery/Truck?

This mystery plate image was recently posted by Rick Kretschmer.  I contacted Rick and Eric Tanner for their take on the plate, as it does not fit any known 1931 format.  It should be noted that in 1931 Truck plates went back to using the R through Z prefix to indicate the weight class.  Eric offers a possible explanation where he suggests how this plate could be part of an early group of Truck plates.  This plate is also not a stand-alone oddball or error.  Enough 2 and 3 digit plates with 2-letter suffixes have been seen including 96AC, 793AC, 277AH, 176BB pair, 43BC and 987BC suggesting these are part of a series.

Eric suggests that the plate shown here is part of a group of 1931 R-weight truck tags which were made well ahead of time using the 1930 system before the decision was made to switch to a new system for 1931 truck plates. Maybe they ran off 25,000 pairs before the change? That would take us from 00AA to 999BE. Too many to waste, so they issued them anyway, Eric offers as a possible explanation.

Eric has also done some math calculations, adding up the known number of R-series plates, plus the series described here, resulting in a total number of plates similar to 1929 and '30 plates.  While this is only a theory at this point, and lacks proof, it does offer a plausible explanation.

1968 - 1971 Truck, multi-year

Dark blue on yellow, revised map outline, top legend COMMERCIAL (replacing TRUCK), bottom PENNSYLVANIA, embossed outline for sticker well lower left.  Early plates had 68 etched into the sticker well with no sticker used in 68.  A new plate serial coding system was introduced using CA-10000 as the starting point with C as a non-advancing character and the second letter always advancing last after the numbers.  Plates authorized CA-10000 to CZ-99999.  A small keystone separator was used between the 2-letter prefix and the 5-digit number.  The weight class, number of axles and truck type, although they are still used, are no longer designated by the registration number.

Both the CC-39980 and CL-89915 plates are formatted similarly.

1972 - 1977 Truck, multi-year

Both the CC-76348 and CT-8531 plates are formatted similarly.

from Jeff Lawson

1978 - 1984 Truck, multi-year, renewable to 2000

All new plates issued.  Dark blue on yellow, top legend PENNSYLVANIA, bottom TRUCK, sticker wells upper left and right corners.  Serial coding again using CA-10000 as the starting point with C as a non-advancing character and the second letter always advancing last after the numbers.  After reaching CZ-99999, the series went to 10000-CA and progressed into the CC series.

Format 1 CA-10000 to CZ-99999

Format 2 10000-CA into the CD series

Format 1

Format 2

1984 - 2000 Truck, multi-year, renewable to 2002

Yellow on dark blue, top legend TRUCK, bottom PENNSYLVANIA, sticker well in lower left corner.  Serial coding starting 5 digits+CD as a continuation of 1978 to 1984 progression and ran into the CJ series where it was stopped and a new series starting at YA-00000, then ZA-00000.  As best as I can remember, PennDOT claimed there was a computer issue with too many registrations starting with C.

Format 1 CD etc. in suffix position as continuation of 1978 to 1984 progression to CJ in suffix position.

Format 2 YA-00000 to ZV-99999

1999 - 2004 Truck, multi-year, renewable to present

Dark blue on white with fading bands of blue on top and yellow on bottom, YAA-0000 to YRR-9810 or above, dash separator, PENNSYLVANIA screened across top and TRUCK embossed along bottom.  Sticker well upper left.  Plates valid thru 2017 and likely beyond.  Vanity plates on trucks appear to be issued on the passenger www base, and have limited weight restrictions.

From Steve Ondik

2005 - 2017 Truck, multi-year, renewable to present

Dark blue on white with solid bands of blue on top and yellow on bottom, YSA-0000 to YZZ-9999, then ZBA-0000 to ZKH-9999, keystone separator, PENNSYLVANIA screened across top and TRUCK embossed across bottom.  Sticker well upper left.  Plates valid thru 2017 and likely beyond.  Plates are referred to by many as visitPA plates or solid band plates.  PennDOT uses the term Family of Plates.

At the end of 2016, PennDOT discontinued issuing validation stickers.  Some 2017, and even 2018 stickers are in use but were issued before 2017.

from Ryan Battin

Vanity plates on trucks appear to be issued on the passenger visitPA base, and have weight restrictions not exceeding 14,000 pounds.  The plate to the right is the only vanity spotted with Truck as the legend.  Information subject to verification.

Vanity

from Jordan Irazabal

2017, Truck, multi-year

In December of 2016 PennDOT announced that by the middle of 2017, once the supply of the current plate stock runs out, they will begin issuing slightly redesigned plates. They look similar in design to the current plate but the sticker well where validation stickers were placed has been removed and the outline of a small Pennsylvania map has been put it its place.  2017 is a mixture of both variants.  There is no prototype image of the Truck plate.

Format 1 - up to ZKH-9999, same as older Truck plates on visitPA base, with sticker well, no sticker, no map.  The ZKI prefix was not used.

Note: Plates without the sticker well and without the map outline are not known to exist.

Format 2 - ZKJ-0000 to current high, similar to Format 1 Truck plates on visitPA base but now without sticker well, and with a small map outline in its place.  Plates first seen in mid-May of 2017.
