Delivery Note OCR
Automatically extract data from Delivery Notes.
Mindee’s Delivery Note OCR API uses deep learning to automatically, accurately, and instantaneously parse your documents details. In a few seconds, the API extracts a set of data from your PDFs or photos of delivery notes, including:
- Delivery Date
- Delivery Number
- Supplier Name
- Supplier Address
- Customer Name
- Customer Address
- Total Amount
The Delivery Note OCR API supports documents from all nationalities and languages.
Set up the API
Before making any API calls, you need to have created your API key.
- To test your API, you can use the sample document provided below.
- Access your Delivery Note OCR API` by clicking on the corresponding product card in the Document Catalog
- From the left navigation, go to documentation > API Reference, you'll find sample code in popular languages and command line.

- Replace my-api-key-here with your new API key, or use the "select an API key" feature and it will be filled automatically.
- Copy and paste the sample code of your desired choice in your application, code environment or terminal.
- Replace
/path/to/my/file
with the path to your document.
Always remember to replace your API key!
- Run your code. You will receive a JSON response with your document details.

You can find the prediction within the prediction
key found in document > inference > prediction
for document-level predictions: it contains the different fields extracted at the document level, meaning that for multi-pages PDFs, we reconstruct a single object using all the pages.
Extracted data
Using the above document example the following are the basic fields that can be extracted.
- Delivery Date
- Delivery Number
- Supplier Name
- Supplier Address
- Customer Name
- Customer Address
- Total Amount
Delivery Date
- delivery_date: Delivery Date is the date when the goods are expected to be delivered to the customer.
{
"delivery_date": {
"value": "2019-10-02"
}
}
Delivery Number
- delivery_number: Delivery Number is a unique identifier for a Global Delivery Note document.
{
"delivery_number": {
"value": "INT-001"
}
}
Supplier Name
- supplier_name: Supplier Name field is used to capture the name of the supplier from whom the goods are being received.
{
"supplier_name": {
"value": "John Smith"
}
}
Supplier Address
- supplier_address: The Supplier Address field is used to store the address of the supplier from whom the goods were purchased.
{
"supplier_address": {
"value": "4490 Oak Drive, Albany, NY 12210"
}
}
Customer Name
- customer_name: The Customer Name field is used to store the name of the customer who is receiving the goods.
{
"customer_name": {
"value": "Jessie M Horne"
}
}
Customer Address
- customer_address: The Customer Address field is used to store the address of the customer receiving the goods.
{
"customer_address": {
"value": "4312 Wood Road, New York, NY 10031"
}
}
Total Amount
- total_amount: Total Amount field is the sum of all line items on the Global Delivery Note.
{
"total_amount": {
"value": 204.75
}
}
