How to read a state ID spec sheet

Most US states publish publicly accessible documentation about their driver's license designs. Knowing how to find and read these documents is useful for understanding what a genuine card should look like before ordering.

Where to find them

The AAMVA (American Association of Motor Vehicle Administrators) publishes DL/ID Card Design Standards that contain specifications for each participating state. The public versions of these documents describe the card layout, field positions, and some (not all) security feature placement. Some states publish their own design specifications through their DMV websites, particularly when launching a new card generation to inform acceptance by businesses and law enforcement.

A Google search for "[state] driver's license design specification" or "[state] DMV ID card specifications" often surfaces official PDFs, particularly for recent redesigns where the state wants businesses to recognize the new format.

What specifications contain

Publicly available specs typically include: card dimensions and format (landscape vs portrait), field positions and sizes for standard data elements, font specifications for readable fields, general security feature descriptions (without technical production details that would aid counterfeiting), and machine-readable element locations (barcode position, mag stripe track).

What they do not contain: specific UV ink formulations, holographic design production details, or substrate specifications — these remain proprietary to the document security contractors who produce the cards.

How to use this information

When evaluating a vendor card, the publicly available specifications give you a baseline for field position accuracy, card format, and general layout. You can measure field positions on a vendor card and compare against stated dimensions. Layout errors that deviate from the specification are easy to identify with basic tools. This is more reliable than trying to compare from photos, which have perspective and scale distortion.

Having a printed or saved reference copy of the state's current spec sheet also helps with proof review when the vendor sends a digital mockup. Comparing the vendor's proof directly against the spec dimensions for the specific field you want to verify is faster and more reliable than comparing from memory. The 15 minutes spent locating and saving the relevant spec sheet before ordering reduces the risk of approving a proof with an error that would have been immediately apparent with a reference in hand.
