Taiwan National ID Card OCR API with Python

Working with the National Identification Card

The Taiwanese card prints Chinese text on both sides, with the ten-character ID number on the front and the address on the back. Re-keying these values is slow, and generic OCR still leaves your team to map each text fragment to the right field.

Structured Extraction for Your Backend

The National ID OCR API returns the ID number, names, dates, and address when they are printed on the submitted side of the card. Test it with the free ID card scanner.

Common Integration Scenarios

• Customer onboarding: Pre-fill identity fields from the National Identification Card before the customer confirms them.
• Account operations: Reduce manual transcription when staff enter identity data.
• Document review: Store normalized output next to your own review decision.

Taiwan National ID Card OCR API with Python

The official Python SDK reads a local file and calls /v1/national-id from your backend.

Prerequisite: `pip install structocr`; set the server-side `STRUCTOCR_API_KEY` environment variable.

Prefer another stack? Open the Node.js SDK + Express integration.

import os
from structocr import StructOCR

client = StructOCR(os.environ["STRUCTOCR_API_KEY"])
result = client.scan_national_id("id-card.jpg")

if result.get("success"):
    data = result["data"]
    print(data.get("document_number"))
    print(data.get("given_names"), data.get("surname"))
else:
    print(result.get("error"))
