Container OCR for Yards, Depots & ICDs in Southeast Asia

High Volume, Every Working Day

Container depots, ICDs and yards across Southeast Asia (from Laem Chabang and Lat Krabang to Singapore, Port Klang, Cat Lai and Tanjung Priok) log containers in and out all day. Surveyors and checkers photograph each box for gate-in, gate-out, damage surveys and stock checks, and the container number still gets typed from the photo, often hundreds of times a day.

Photos In, Validated Numbers Out

Send each photo to the StructOCR Container OCR API and get the 11-character container number with an ISO 6346 check-digit result. Full-resolution phone or camera photos work as they are; there is no need to crop. Integrate it into your depot or yard system from Python, Java or any other language, and test photos first in the free container number scanner.

Where Teams Use It

Integration & AI Prompts

Batch your photos through one endpoint. Full request and response details are in the container API reference.

import base64, os, pathlib, requests

API = "https://api.structocr.com/v1/container"
headers = {"x-api-key": os.environ["STRUCTOCR_API_KEY"]}

for photo in sorted(pathlib.Path("gate_in_photos").glob("*.jpg")):
    img = base64.b64encode(photo.read_bytes()).decode()
    data = requests.post(API, headers=headers, json={"img": img}, timeout=30).json().get("data", {})
    print(photo.name, data.get("container_number"), "valid" if data.get("is_valid") else "check")

{
  "success": true,
  "data": {
    "container_number": "SOCU7345122",
