I assume they've built a system to handle all of these unique cases and use some type of OCR to verify everything matches up with both the encoded barcode data as well as the Driver's License number which is partially derived from the demographic data. As a result, it's a real pain to try and use the standard without accounting for each state's unique set of quirks which tend to change from year to year. Unfortunately, there isn't a national system for encoding the data as described in the specification and some states still maintain different fields than others. The magnetic strip varies by state but the PDF417 barcode is supposed to follow DL/ID Card Design Standard (CDS) as defined by the AAMVA. The other barcodes, though? We can’t know what information is encoded there for security reasons.īamboozled: What the bar codes on your driver’s license reveal about you, and why it matters Įditor's Note: This article originally appeared on Consumerist.I did some work on a similar app a few years ago so I have some insight on the subject.
That’s to prevent people from altering the front of their license–say, the year of their birth. There’s your name, birthdate, address, height, and weight. What the MVC, New Jersey’s motor vehicle agency, could tell her was that some of the data embedded on the back of your license is the same information that’s on the front of your license. Lots of extensive reporting got her…well, she found out what one of the barcodes means, but what the other one contains is a mystery that mere mortals are not allowed to understand. Yet people often wonder what information is embedded in those barcodes, and consumer problem-solving columnist Karin Price Mueller of the Star-Ledger decided to find out. We use driver’s licenses as photo ID for everything from buying cold medicine or booze to boarding a plane, in addition to using them as proof that we’re legally permitted to drive. There’s a lot of information about you on the back of your state-issued driver’s license or non-driver ID card, but does scanning your license or making a copy of it give potential identity thieves key information about you? It’s not easy to find out what data is encoded in the barcodes on the back of your ID cards, and your state’s motor vehicles department may not want you to know.
