Container OCR API for UK Logistics

Automate terminal gates and rail portals from Felixstowe to Southampton. Accurately extract ISO 6346 codes through heavy rain and overcast conditions. Upload your image for a free instant test.

The Reality of UK Port and Customs Automation

UK ports and logistics parks face a dual challenge: navigating post-Brexit border friction that demands hyper-accurate data logging, and battling unpredictable British weather. Capturing container codes frequently fails when optical scanners are obscured by heavy rain, fog, and low-contrast lighting. Furthermore, complying with strict local data standards means relying on complex, outdated on-premise hardware rather than agile cloud systems. For a deeper dive into overcoming these specific environmental hurdles, see our core Container OCR capabilities.

StructOCR: Agile Infrastructure for Modern UK Trade

Engineered strictly as a high-performance REST API to ensure seamless integration into UK Customs and logistics platforms without heavy SDK dependencies, this endpoint is powered by our resilient Logistics Container OCR engine. It features complete rotation invariance—automatically reading upside-down text. The engine applies strict ISO 6346 validation to mathematically verify the owner code and check digit, guaranteeing absolute data integrity for compliance records.

Core Applications for the UK Market

Post-Brexit Customs Clearance

Accelerate freight clearance. Automatically cross-reference visually extracted container numbers with digital customs manifests (CHIEF/CDS) in real-time. Ready to optimize? View flexible pricing to integrate high-speed processing into your compliance software.

Automated Port Gates (Felixstowe/Southampton)

Process inbound and outbound trucks flawlessly. Identify ISO 6346 codes instantly as HGVs pass through terminal checkpoints, despite adverse weather.

Inland Intermodal Rail

Deploy across extensive inland rail corridors connecting coastal ports to the Midlands. The API natively handles high-speed captures of moving freight trains.

Logistics Park Access Control

Automate security barriers at major distribution centers by matching approaching container codes against expected arrival schedules securely via internal Base64 payloads.

Technical Specs

  • Validation: Built-in ISO 6346 checksum verification.
  • UK Edge Optimization: Infrastructure is routed through Cloudflare's global edge network, with primary processing nodes in London providing ultra-low latency.
  • Rotation Invariance: Native support for 0°, 90°, 180°, and 270° orientations without manual pre-processing.
  • Input Versatility: Fully supports raw Base64 strings and direct multipart file uploads to align with strict corporate data handling policies.

Key Features

  • ISO 6346 Parsing: Perfectly isolates the 3-letter Owner Code (BIC), 1-letter Equipment Category, 6-digit Serial Number, and 1-digit Check Digit.
  • Harsh Weather Tolerance: Advanced filtering mitigates image noise from rain, fog, dirt, and heavy cloud cover common across the UK.
  • Zero SDK Overhead: Integration requires no native dependencies, keeping your compliance and logistics applications lightweight.

Integration & AI Prompts

Call the endpoint directly via HTTP. The API securely handles raw Base64 strings and direct multipart file uploads, ensuring sensitive logistics imagery doesn't require public URL hosting.

Standardized JSON Output

The API returns a cleanly parsed payload breaking down the ISO 6346 components, validating the check digit, and providing a structural confidence score.

{
  "success": true,
  "data": {
    "container_number": "ZCSU8921655",
    "is_valid": true,
    "confidence": "High",
    "parsed": {
      "owner_code": "ZCS",
      "category": "U",
      "serial_number": "892165",
      "check_digit": "5"
    }
  }

Frequently Asked Questions

Can I test the API with my own images for free before subscribing?

Yes! You can utilize our free image test directly on the platform to upload your own challenging UK captures and instantly verify the extraction accuracy.

How does the API handle upside-down text from top-down crane cameras?

The engine features complete rotation invariance. It will automatically detect, rotate, and read text that is 180-degrees inverted without requiring you to rotate the image payload first.

Does sending images to the API violate strict data privacy requirements?

The API accepts Base64-encoded strings and direct file uploads, meaning you do not need to host sensitive images publicly. Furthermore, images are processed statelessly in memory and are never retained.
