Indiana '5G' Plate Marks Are Date Codes

Indiana officials say a '5G' mark on license plates identifies reflective sheeting production date, not wireless tracking capability.

Do you trust the government to limit how it tracks your vehicle?

A viral Facebook video posted June 4, 2026 claimed Indiana license plates labeled '5G' contain wireless tracking capabilities. The Indiana Bureau of Motor Vehicles said the mark is a manufacturer's date code for the plate's reflective sheeting.

Why it matters

The claim spread widely among Indiana drivers concerned about surveillance, and the date codes help state officials trace faulty reflective sheeting batches. Standard-issue plates do not support wireless connectivity.

The Indiana BMV sent AFP photos of plates bearing other similar codes, including 3S and 5H, to support its explanation. Standard-issue plates support neither Bluetooth nor LTE connectivity, while the $899 Reviver RPLATE digital plate does.

The players

Indiana Bureau of Motor Vehicles

The state agency responsible for vehicle registration and license plate issuance in Indiana, which identified the '5G' mark as a manufacturer's date code.

The multinational manufacturer whose Preclear plate sheeting carries the date marks, and which offers up to a five-year warranty on the material.

The details

The mark is a small code on the side of the plate that helps the BMV identify when the reflective material was produced. 3M's April 2026 bulletin for its Preclear plate sheeting confirmed that such marks identify the year the film was made.

2015: California began testing e-ink digital license plates in a pilot program.
2022: California opened digital plates to all drivers.
April 2026: 3M published its bulletin on plate sheeting date marks.
June 4, 2026: The viral Facebook video claiming 5G plates track vehicles was posted.

Telecommunications Context

California began testing e-ink digital license plates in 2015 and opened them to all drivers in 2022, establishing that connected plates are a deliberate, purchased product. Standard reflective plates carrying date codes are a separate technology that has no wireless component.

Indiana drivers with standard plates marked '5G' do not have wireless tracking hardware, so no action is needed to disable a device. The date code is a manufacturing marker that officials use to trace faulty reflective sheeting batches.

The takeaway

Drivers can distinguish manufacturing date codes from connected hardware by checking whether a plate carries any electronic components, since standard reflective plates do not. Viral claims about surveillance should be checked against official agency statements before being shared.
