Auto Transport Bill of Lading (BoL) OCR

Automate large-scale vehicle logistics. Accurately extract single or multiple 17-character VINs from dense transport manifests and Bills of Lading, completely bypassing carrier details and delivery tables.

Extracting multiple 17-digit VINs from a table on a vehicle transport Bill of Lading.

The Density of Logistics Manifests

Processing an automotive Bill of Lading (BoL) or transport manifest is a high-stakes data extraction task. Unlike single-vehicle documents, a BoL is dominated by dense tables and grids containing load codes, carrier addresses, delivery statuses, and frequently, multiple vehicles on a single page. Traditional OCR engines strip the document of its layout, vomiting out a massive wall of unstructured text where the 17-character VINs are lost among tracking numbers and weight metrics. Additionally, these documents are often carbon copies or low-resolution scans from truck cabs. For a deeper dive into how we handle complex tables, see our core OCR product capabilities.

StructOCR: Built for Logistics Tables

StructOCR intelligently parses tabular logistics data. Powered by our flagship Automotive VIN OCR API, it scans the grid structure, actively ignoring carrier terms and shipping addresses. It utilizes spatial recognition to locate the target alphanumeric strings and applies strict ISO 3779 validation. Whether the manifest contains one vehicle or a batch of ten, the engine ensures only valid chassis sequences are extracted and formatted cleanly for your Transportation Management System (TMS).

Technical Specs

  • Table Parsing: Specifically designed to navigate dense grid layouts and multi-column manifests
  • Validation: Built-in ISO 3779 rules & Length constraint (strictly 17 chars)
  • Latency: < 1.5s per complex document via API
  • Data Privacy: Zero data retention (SOC2 Compliant)

Key Features

  • Tracking Number Bypass: Intelligently ignores long tracking or container numbers that do not match ISO checksum logic.
  • Carbon Copy Enhancement: Recovers text from degraded, low-contrast physical carbon copies common in trucking.
  • Format Support: Accepts raw Base64 or Data URIs (JPG, PNG, WebP, PDF up to 4.5MB).

Standardized JSON Output

The API returns a clean, structured payload containing the validated 17-character VIN(s), structural confidence, and identifies the carrier as a document.

{
  "success": true,
  "data": {
    "vin": "3VWXX123456789012",
    "confidence": "High",
    "carrier_type": "document"
  }
}

Frequently Asked Questions

Can the API handle a BoL that lists multiple vehicles?

Yes. Our extraction engine scans the entire document for valid ISO 3779 structures. Depending on your endpoint configuration, it can extract and return an array of all validated VINs found on the page.

Will it confuse a long tracking number or container ID with the VIN?

No. Our visual grounding models use strict ISO 3779 checksum mathematics. Tracking numbers and container IDs do not follow this global automotive standard, so the system effortlessly ignores them.

Truck drivers often submit terrible photos of carbon copies. Will it work?

Our deep learning pre-processing is optimized for legacy document artifacts. It cleans up the digital noise and low contrast typical of cab-scanned carbon copies to reconstruct the target text.
