Already have an EAN or UPC barcode number?

Create barcode images and download best optimized graphics for barcode readers and scanners.

Fill in your GTIN barcode number to get started the design of your unique barcode labels.

Fill your first and last names, company name, your product names for which you are buying a barcode, and the email to which we will send the barcode (If you need to buy more than 5 barcodes, you need to register).

Wait for your barcode: it would take 5-10 seconds to get back to your order page and also to get an email from info@barcodes.pro with your order details and download link. All UPC and EAN barcodes will be sent in SVG, PNG image formats and in XLS, CSV spreadsheets.

The European Article Number (EAN) is a Global Trade Item Number standard describing a barcode symbology and numbering system. It's used in global trade to identify a specific retail product type, from a specific manufacturer.

Universal Product Code version A is a 12-digit barcode for uniquely identifying a product and its manufacturer. This barcode was orginally developed for use in North America and was later expanded for worldwide use as the EAN13 barcode.

Generating this barcode using the Barcode GeneratorThe easiest way to create this barcode is to use the Barcode Generator included in the installation package. Simply goto the Start Menu and launch Aeromium Barcode Fonts > Barcode Generator. This software automatesand simplifies the creation of the barcodes for you. After the barcode is created, you can simply copyand paste the barcode into your documents.

Generating this barcode using the Barcode Generator

Generating this barcode in Excel

The UPCA barcode uses a Parity table to generate the barcode and the computation of the barcode font characters involves certain amount of complexity. It is thus recommended to use the Barcode Generator or Excel Add In to generate the barcodes instead of creating them manually.

Sample BarcodesTo encode the data "01234567891", simply key in "01234567891" in the Barcode Generator. The output is as follows :

Selecting the Extended Style results in the following barcode :

NOTE: To verify that the font was downloaded, open the fonts folder ( C:WindowsFonts). Click the Date Modified column to sort by the most recent date that the file was modified. The four font files should appear at the top of the list.

Unless you create hundreds of barcodes a week, I recommend using one of the free online barcode generators mentioned above or (if applicable), one of the free barcode fonts listed above. There are add-in programs you can use in Excel to create these barcode fonts, but they are neither free nor cheap. All three programs listed below, however, offer free trial versions.

Hi everyone! ? I have always been fascinated by barcodes and QR codes. I have known for a long time about how they work in theory but I never did enough research on it. It seemed like I would learn a lot from diving deeper and implementing a barcode generator from scratch. There is no substitute for learning more about something by creating it from scratch so that is exactly what I did.

The barcode was invented by Norman Joseph Woodland and Bernard Silver and patented in the US in 1951. The invention was based on Morse code that was extended to thin and thick bars. However, it took over twenty years before this invention became commercially successful.

The idea for an automated entry system (barcode) originated when a Drexel student overheard a food chain owner asking for a system to automatically read product information during checkout. No doubt the barcode later found huge commercial success in the retail industry!

The way the information is encoded in a barcode is called the symbology. Some symbologies allow storing alphabets but some only allow storing digits. There are tons of different symbologies out there and each is prevalent in a different industry.

In this article, we will be focusing on the UPC-A barcode. This is type A of the Universal Product Code barcode. It only allows storing digits (0-9) in the bars. I chose it for this article because it is super simple and quite a few other codes are just an extension of this.

The symbology for UPC-A only allows storing 12 digits. The first digit, Number System Character, decides how the rest of the digits in the barcode will be interpreted. For example, If it is a 0, 1, 6, 7, or 8, it is going to be interpreted as a typical retail product. If it starts with a 2 then it is going to be interpreted as a produce item that contains a weight or price. The next 10 digits represent product-specific information and the interpretation depends on the NSC. The last digit is a check digit and helps detect certain errors in the barcode.

The check digit allows the barcode reader to detect certain errors that might have been introduced into the barcode for various reasons. Each symbology uses a specific formula for calculating the check digit. The check digit equation for UPC-A looks like this:

Wikipedia provides very good visualization for what the barcode encoding looks like for UPC-A. There are two sets of digits that are divided by a middle guard. Each digit is encoded by 7 vertical lines or modules. Each of these can be either black or white. For example, 0 is encoded as WWWBBWB.

The digits from 0-9 are encoded slightly differently on the left side of M (middle guard) vs the right side. A fun fact is that the right side encoding of a digit is an optical inverse of its left side encoding. For example, the 1 on the left side is encoded as WWBBWWB and the 1 on the right side is encoded as BBWWBBW. A reason for this is that this allows barcode readers to figure out if they are scanning the barcode in the correct direction or not. Some scanners would do two passes, once reading from left to right and once from right to left and some would simply reverse the input data without a second pass if it started scanning from the wrong direction.

The very first step in creating our custom barcode generator is to define the encoding table for the digits and the guard bars. Start by creating a new barcode_generator.py file and adding this code to it:

The MODULE_WIDTH and the other sizes are all taken from Wikipedia. These are the dimensions of a typical UPC-A barcode in the normal sizing. You can tweak these sizes to an extent and the barcode should still work fine. The EXTENDED_MODULE_HEIGHT refers to the height of the modules or bars for the three guards (L, M, R) and the first and last digit (check digit) of the UPC. These modules are generally taller than the other modules. This extended height is also taken from Wikipedia. The barcode is still valid without this height difference but it looks nice with this height difference and shows a clear separation of the left and right digits. For example, compare these two barcodes:

I am using list slicing to get the even and odd digit positions and then doing some arithmetic for the check digit calculation. It might have been better to let the user input the check digit and then compare that to our calculated check digit and make sure the entered barcode is correct. It would have made the barcode entry more robust but I will leave that error detection up to you.

I really enjoyed diving deeper into barcodes and learning more about their history and implementation. This is a very fascinating field and I do plan on exploring it more in the future. I will probably try to tackle QR codes next as they are slowly replacing barcodes everywhere and can encode a lot more information in a much smaller space. It would be fun to try and implement a QR code generator in Python.

EAN-13 and UPC-A barcodes are widely used to identify retail items.The barcodes encode 13-digit and 12-digit number respectively. At the firstglance, it is easy to create them. Unfortunately if you are using thefont-based solution, it is not that easy as you may think. There area couple of reasons:

An EAN-13 barcode encodes a 13-digit number. This number has a checkdigit at the end based on modulo 10 algorithm. Using Morovia UPC/EAN/Booklandfonts, a total number of 15 characters are needed to encode the wholebarcode symbol, as depicted below:

In our case, the first digit is 9, the encoding pattern fordigit 2 to digit 7 should be OEEOEO according to thetable above. Because all of them print human readable text below, theshcemes B and D are used. The left-hand odd encodings for digits 7 and 5are themselves (7 and 5). The left-ahdn even encodings for digits 8, 0 and3 are i, p and e respectively. Adding them all together we get the barcodestring for this part: 7ip7e5. ff782bc1db
