Have you ever heard of a 2D barcode generator?

Well, it is a tool that assists you in creating 2D (two-dimensional) barcodes effortlessly.

But based on your use case, there are several barcode generator options that you can choose from, which will be mentioned in detail in this post.

So let’s get started!

What Is A 2D Barcode?

Two-dimensional, or 2D, refers to a collection of small geometric forms arranged inside of a rectangle or square to hold data.

They give hundreds of times more data than a 1D barcode can hold because they can store data in both the horizontal and vertical planes.

More than 7,000 characters can be stored in a single 2D barcode, which can contain data like the brand name, maintenance records, model number, and a variety of other specifics.

A 2D barcode differs physically from a conventional linear 1D barcode in appearance.

What Are The Types of 2D Barcodes?

Today, there are three main forms of 2D barcodes. 

3 common types of 2D barcodes

  • QR codes

Quick response codes, sometimes referred to as QR codes, maybe the most widely used 2D barcode. 

The QR codes, which can be read by smartphones and take visitors directly to websites, were first employed in Japan to track vehicle parts.

  • Data Matrix codes

Imagers or readers that effectively take a picture of the code and then analyze it are required to read data matrix codes. 

They are frequently employed in commercial applications.

  • PDF417 codes

By simply stacking rows of codes inside of one another, PDF417 codes can safely and economically contain a lot of information.

What Are The Uses of A 2D Barcode?

A 2D barcode can be utilized in several ways across a variety of industries.

Healthcare and manufacturing

Regarding 2D barcodes, there are many connections between healthcare and manufacturing.

For instance, 2D barcodes can be utilized for pharmaceutical product authentication and traceability.

They can also be etched into metal like a stent in medicine or a tiny metal component in manufacturing, which can help with traceability.


Pharmaceuticals frequently come in very small containers, and since a 2D barcode may fit in very little space, you can cram a lot of information into it.

It can include a serial number, batch information, a description of the product, and even a URL where you can find out more about it.


Retailers can benefit greatly from the usage of 2D barcodes; a notable example is the addition of 2D barcodes in food stores.

For instance, they can add much more information to the barcodes for their meat products.

Expiration dates and batch information can be added, which could help to reduce the number of product recalls, food waste, and sales of expired goods.

Warehouse and logistics

If a tiny package arrives, warehouses frequently get products with 2D barcodes already attached.

For instance, a 2D barcode might be printed on the delivery label, and both the barcode and the information can be quickly scanned and interpreted.

Thus, there is no need for a connection to a backend or outside services.

Frequently Asked Questions (FAQs)
1. Is a QR code a 2D barcode?

Quick response codes, or QR codes, are 2D codes that were developed in 1994 by the Japanese automaker Denso Wave.

On a white background, a square grid of black cells makes up the object. Up to 4,296 alphanumeric characters can be stored in it. 

The number of rows and columns mostly determines how many characters are allowed.

2. Can phones scan 2D barcodes?

Using a free app from the App Store or Play Store, your smartphone can scan any barcode or QR code.

The camera on your device can be utilized as a scanner when the barcode scanning software has been installed.

3. How much information can a 2D barcode hold?

In actuality, 2D barcodes have a storage capacity of up to 7,089 characters, which is a lot more than the 20-character limit of conventional barcodes.


That is all for today’s post on a special type of barcode, which is two-dimensional code. After reading this post, we hope you are clear about how to create 2D barcodes generally and QR codes particularly using an online 2D barcode generator, barcode software, and Excel.
