2025 ID FRAUD REPORT: Business risk skyrockets as ID fraud rises

Understanding interlocking IDs and how to identify them in the U.S. and Canada

Breathalyzer device for interlocking IDs

When it comes to ID verification and security, not all driver’s licenses are created equal. One type that stands out for its added complexity and security measures is the interlocking ID. Understanding what these are, how they work, and how to flag them during a scan is crucial for professionals in law enforcement, retail, hospitality, and any sector where ID validation is routine.

What are interlocking IDs?

Interlocking driver’s licenses refer to a specialized format that indicates when a driver must perform a breathalyzer test prior to driving a vehicle. The visual elements and encoded data (such as the barcode or magnetic stripe) are designed to “interlock” across jurisdictions or systems. These licenses often appear very similar between states, making them easier to validate consistently across borders. This is especially important for insurance providers, car rental facilities, logistics companies, etc.

Key Security Features

Like most modern IDs, interlocking drivers licenses include several built-in security features that are standardized by the ICAO:

  • Holograms and ghost images
  • Microprinting and UV ink
  • Barcodes and magnetic stripes – Encoded with data that must match the printed information.
  • Star symbol for newer REAL IDs
  • Tactile text or raised lettering

These elements not only prevent fraud but also allow scanning systems to alert businesses when extra precautions may need to be taken. 

How to Flag Interlocking Licenses During a Scan

Interlocking IDs may employ the use of additional security features, but that doesn’t prevent them from being scannable. VeriScan, whether on a computer, iPhone, or Android, can detect interlocking IDs with a simple scan of the barcode. Once an interlock ID is scanned, VeriScan will then display a pop-up to alert businesses that the driver must first complete a breathalyzer prior to vehicle operation.
