Founded, 1776; population, 13,002,700; capital, Harrisburg.

Pennsylvania utilized enamel plates from 1906 to 1915; plates from 1916 to the present are of metal.

A metal “43” tab was used on the 1942 base plate. Paper expiry stickers were used from 1959 to 2017.

For a period of 67 years (1923-1990) Pennsylvania plates were issued in alternating navy-on-gold, gold-on-navy formats.

In May 2025 Pennsylvania issued the Let Freedom Ring plate design: registration lettering and digits in blue, and state name and slogan in red, all on a white background. For the first time since 1958 the plate design lacks the keystone symbol, and registration numbering now includes a “slashed zero”. Registrations have now reached NFD 1234 for passenger cars, VCN 1234 for commercial vehicles (pick-up trucks, vans, etc), and XRS 1234 for trailers.
