Connecticut Driver License & ID Card PDF417 API

Reading Connecticut Card Barcodes in Real Workflows

Connecticut casino and insurance workflows are high volume but low tolerance for data errors. Rushed captures at entry points produce tilted, partially cropped barcodes. PDF417 error correction recovers some damage, but an application should never invent identity values when the barcode cannot be decoded.

One API for Connecticut Licenses and ID Cards

Connecticut cards are issued by the Connecticut Department of Motor Vehicles. Licenses and identification cards carry the same AAMVA DL/ID PDF417 barcode on the back. Send the back image to the StructOCR PDF417 API: it decodes the barcode deterministically, normalizes the jurisdiction to CT, and returns document_kind as driver_license or id_card. Test a non-sensitive sample in the free PDF417 scanner. For the printed front of the card, use the Driver License OCR API.

Where This Workflow Fits

• Casino guest registration: Pre-fill names, dates, and address for casino guest registration and keep final confirmation in your application.
• Insurance customer onboarding: Accept both Connecticut licenses and state ID cards, and use document_kind where only a license is acceptable.
• Commuter parking accounts: Send unreadable Connecticut barcodes to a retake or manual review step instead of saving partial identity data.

Decode a Connecticut Card Back

Upload a JPG, PNG, or WebP image of the full card back. Ask for the back of the card to fill most of the frame, with a small margin on every side and no fingers over the barcode.

Prerequisite: A server-side StructOCR API key and a clear image of the complete card back

Illustrative Connecticut ID Card Response

This response uses wholly fictional data to show a CT identification card. A license returns document_kind driver_license and its class fields.
