India Aadhaar OCR with Node.js SDK

Working with the Aadhaar card

The Aadhaar card places the holder's identity number and biographical details in a country-specific layout. Re-keying those values is slow, while generic OCR still leaves a backend team to identify each text fragment and map it to a database field.

Structured Extraction for Node.js Backends

StructOCR accepts a Base64-encoded image or PDF and returns normalized national ID fields. For a readable Aadhaar card, the response can include the Aadhaar number, name, dates, issuing information and address when those values appear on the submitted document.

Common Integration Scenarios

• Customer onboarding: Pre-fill visible identity fields from a Aadhaar card before user confirmation.
• Account operations: Reduce manual transcription when staff enter identity data into an internal workflow.
• Document review: Store normalized API output alongside the original review decision in your own system.

India National ID OCR with Node.js

The official Node.js SDK reads a supported local file and calls /v1/national-id. Open the TypeScript + Express tab for a server route using the same SDK method.

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

Prefer another stack? Open the Python SDK + FastAPI integration.

const StructOCR = require("structocr");

const client = new StructOCR(process.env.STRUCTOCR_API_KEY);

async function main() {
  const result = await client.scanNationalId("id-card.jpg");

  if (result.success) {
    const data = result.data;
    console.log(data.document_number);
    console.log(data.given_names, data.surname);
  } else {
    console.error(result.error);
  }
}

main().catch(console.error);
