2D Barcodes – grouped under this are the QR codes manufactured using squares, dots, and shapes to preserve details such as an image of the product.
This system enables all kinds of businesses to quickly get all the information about products using smartphones or scanners.

How to Extract ASIN, UPC and Walmart Product Codes?
Web scraping is especially advantageous if one is dealing with many products at a time or require periodical update of product data. There are different opportunities to adjust different tools that would allow to perform this work systematically and properly.
How to Extract ASIN Information?
The need to extract the ASIN (Amazon Standard Identification Number) is crucial for any business or individual that requires compiling and organizing product information from Amazon. The process can be simplified into a few easy steps:The process can be simplified into a few easy steps:
Go to the Product Page on Amazon
First, go to the page where the specific product you are interested in it is available. Amazon as an online selling platform provides millions of products in its catalog, and it can be a good reference source for finding product information, including the ASIN.
The ASIN can be found in the Product Details Section
On the same page, go down or look for the information tab, labeled “Product Details”. Here there is normally identification number referred to as ASIN usually provided. The ASIN refers to the identification code for Amazon products, which may be labeled as ASIN or Amazon Standard Identification Number.
Two Ways to Extract the ASIN
Manual Method: You can just copy it from the product page along with ASIN. What is good for one or two products is not very convenient when handling data in large quantities
Web Scraping: For large operations, there are available web scraping applications. These tools can save much time to read through the pages to collect ASINs and other product details at a time.
How to Extract UPC Information
Extracting UPC (Universal Product Code) information is essential for various business and inventory management tasks. Here’s how to retrieve UPC information using different methods:
Check the Product Packaging
In the case of material goods, the UPC is normally in the form of bar code that is attached to the container of the product. This is composed of digits and lines on the code, and assigns a distinct number for the product. All you need to do is take a look at the packaging to identify and write down the listed UPC.
Barcode Scanner Application
You can also any access a smartphone and bury scan the barcode. You can get many mobile phones that have their inbuilt application to scan barcodes or have a barcode scanner application. Click on the application to open it, aim the smartphone’s camera at the barcode and allow the application to scan the code. The UPC will be displayed in a simple typographical format for your convenience to jot down or make references wherever or whenever necessary.
Retrieve Through an API or Web Scraping
For larger inventories or e-commerce data, using APIs or web scraping can be more efficient. Some platforms provide APIs, such as Walmart’s UPC lookup, that let you automatically access UPC data for multiple products. This is ideal for managing bulk data.
Alternatively, web scraping can extract UPC information from websites when APIs aren’t available. Tools can be programmed to scan web pages, find UPCs, and organize them in a structured format, making it useful for extensive product data extraction.
Choosing the Right Method
Manual extraction from packaging works well for small operations. Barcode scanner apps are convenient for scanning individual products. APIs and web scraping are ideal in large inventories since they are automated.
Listed methods have their own benefits and it is up to you to decide which one you will use. Getting UPC data is more essential in tracking inventory, setting prices, and identification of products, especially when dealing with large sites like Walmart.
