It’s difficult to imagine life without barcode labels. While we don’t typically think of barcode labelling as playing a core role in our lives, their existence makes numerous aspects of living easier. From grocery shopping to conducting business - across the globe, businesses rely on barcode labels to track their products from acquisition to the final sale.

But why is barcode labelling so important? And what does it actually mean? To answer these questions, we’re going to look at the significance of barcode labelling, what barcode digits mean and clarify how many digits are in a barcode.

What is a barcode label?

Simply put, barcodes are a visual representation of data that is presented in a machine-readable form. Everyone can envision the parallel black lines of varying sizes and widths that constitute a 1D barcode, and the single row of digits printed beneath the rectangle of bolded lines. But what does all of this cryptic information signify?

In 1948, two American inventors - Norman Joseph Woodland and Bernard Silver, invented the modern barcode. They used morse code to create a system that would make it much simpler for supermarkets to automatically read product information during checkout. Since the 1950s, barcode technology has grown exponentially and now includes various forms, including QR codes and other 2D barcodes.

Traditionally, barcode labelling is used in shops to mark and track inventory. Individual labels that differentiate between various products are extremely useful when it comes to providing customers with a quick and accurate checkout experience. Barcode scanners allow us to extract meaningful information from a simple collection of vertical lines.

Outside of retail, barcodes are also used in numerous other settings. Healthcare facilities and hospitals rely on barcode labelling to identify patients and create medical records. Other industries that use barcode labels to identify products (and people) include airlines, entertainment and sporting facilities, government enterprises, schools, home businesses, manufacturers and countless other business types.

Benefits of Using Barcode Labels in Business

Using barcode labels in business brings a wide range of benefits that improve overall operations. One of the key advantages is efficiency—barcode scanning speeds up processes like inventory management, shipping, and checkout, reducing time spent on manual data entry. Accuracy is another major benefit, as barcode labels minimise the risk of human error by automating data collection, ensuring precise information for tracking stock, managing assets, or processing sales. Additionally, barcode systems are highly cost-effective, requiring minimal training and equipment, and they can easily scale as your business grows. Barcodes also improve inventory control, offering real-time data to streamline reordering, reduce stock discrepancies, and improve decision-making. In all, barcode labels are a practical and efficient solution that enhances productivity, accuracy, and cost management in various industries.

Common Uses of Barcode Labels Across Industries

Barcode labels are versatile tools used across various industries to streamline operations and improve efficiency. Here are some common uses:

• Retail: Barcodes are used for pricing and inventory management, allowing businesses to quickly scan products at checkout and track stock levels in real-time.

• Shipping and Logistics: Barcodes are essential for package tracking, enabling accurate and efficient management of shipments from dispatch to delivery.

• Healthcare: Barcodes are used for patient identification and medication tracking, ensuring safety and accuracy in administering treatments.

• Manufacturing: Barcodes assist in tracking raw materials and finished products, providing real-time data on inventory and production status.

• Hospitality: In the food and beverage industry, barcodes help with menu item tracking, stock control, and pricing adjustments.

• Libraries: Barcodes are used for cataloguing books and tracking loans, making it easier to manage large inventories.

• Pharmaceuticals: Barcodes ensure product authenticity and assist in tracking medicines through the supply chain.

These examples demonstrate the broad applicability of barcode labels in improving accuracy, efficiency, and overall operational performance across industries.

How to Choose a Barcode Label

When choosing barcode labels for your business, it's important to consider the specific application and environmental conditions. The material you select should be tailored to the demands of the industry or environment. Some common options include:

• Thermal paper labels: Ideal for short-term use, such as retail receipts or temporary labels, where exposure to heat or moisture is minimal.

• Synthetic labels: Made from materials like polypropylene or polyester, synthetic labels are highly durable and resistant to water, chemicals, and extreme temperatures, making them suitable for industrial, outdoor, or shipping applications.

• Removable labels: Useful in situations where the label may need to be easily removed without leaving residue, such as in inventory management or retail.

When choosing barcode labels, it’s crucial to choose durable labels that can withstand the specific environmental conditions they will face, such as moisture, heat, or chemical exposure. Using the right label ensures that the barcodes remain scannable and legible throughout their lifespan, helping maintain efficiency and accuracy in operations.
 

How to Make Sure a Barcode is Scannable

The best way to check if a barcode is scannable is to scan it yourself!

Of course, you don’t want to print hundreds of barcode labels only to find out after that you made a mistake in their formatting.

When creating your barcode, there are certain standards you should conform to in order to ensure that your barcode is scannable. Ordering pre-printed barcode labels is a practical way to ensure that your barcodes are readable and durable.

There are numerous factors to consider for your barcode labels that can enhance their overall readability and durability, including:

Material

It’s crucial that you print your barcode on material that has proper contrast. The material shouldn’t be too glossy either as this can impact the scanner’s ability to read the barcode. Most barcodes should be printed with black on a white background as colours are typically more difficult for scanners to read.

Font

There is no universal font used for barcode labelling. Readability is key, so it’s important that the font you choose is readable at a glance. Popular fonts include Times New Roman or Helvetica.

Most barcodes also utilise monospaced fonts, which means that each character occupies the same width. This ensures that the numbers can neatly fit into the barcode.

How Many Digits are in a Barcode?

The exact number of digits within a barcode will depend on what standard is used. There are 4 main types of barcodes used globally: 

EAN

EAN is the European Article Numbering System; an international barcode standard used to identify retail products. EAN has two versions: EAN-13 and EAN-8,  comprised of 13 and 8 digits respectively.

Code 39

Code 39 barcodes are typically used for non-retail applications. This type of barcode can have up to 43 characters that include numbers, letters and symbols. It is also possible to encode all 128 ASCII characters, which can be scanned if a reader is in its “Full ASCII” mode.

UPC

UPC (Universal Product Code) is a coding system and symbology, designed to uniquely identify a retail product and its manufacturer. This type of barcode is a fixed length, and includes 2 variations, UPC-A and UPC-E, encoding 12 and 6 digits respectively.  UPC-E is simply a compressed version of UPC-A and allows manufacturers to encode a limited number of 12 digit products codes in 6 digits, making it more suitable for identifying products in small packages.

ITF-14

As the name suggests, ITF-14 barcodes encode 14 digits and are typically used for the marking of shipping containers and packaging containing trade items. ITF means “Interleaved Two of Five”, indicating that it contains an even number of digits (2-width numeric codes), with each 5 bar section of the barcode containing exactly 2 wide bars.

This barcode encoding format is mostly used to encode GTIN-14 (Global Trade Item Number) data, a globally unique 14-digit number used to identify trade items, products, or services.

What Specific Barcode Scanners Should You Use?

With a seemingly countless number of barcode scanners out there, it can be difficult to determine which one is best for your business.

Barcode scanners are typically divided into two categories: laser scanners and imagers.

Laser scanners are intended to be used on traditional linear barcodes (also known as 1D barcodes). These types of scanners can come in standard range or long range.

Meanwhile, imagers can also read patterns and shapes, such as those within a QR code, Data Matrix or any other 2D barcode. They are considered more versatile than laser scanners as they can scan a greater amount of data.

It’s also important to consider environmental factors that may impact the use of the barcode scanners. Barcode scanners that will be handled in warehouses or factories should be durable and built specifically for extreme environments. If your scanner will be used in a retail setting, you may want to consider a fixed mount scanner or possibly a cordless scanner.

Ultimately, even the most high-tech barcode scanner requires quality, durable barcode labels to function.

The Role of Thermal Printers in Barcode Labelling

Thermal printers play a vital role in barcode labelling due to their efficiency, speed, and ability to produce high-quality labels. They are ideal for barcode printing because they deliver precise, clear images, ensuring that barcodes are scannable and legible, even for small labels. There are two main types of thermal printing used for barcode labels: direct thermal labels and thermal transfer labels. Direct thermal printing uses heat-sensitive paper and is best for short-term applications like shipping labels or receipts, as the labels may fade over time with exposure to heat or sunlight. In contrast, thermal transfer printing uses a ribbon to transfer ink onto the label, producing highly durable and long-lasting labels that can withstand harsh environments, making it perfect for industrial or outdoor use. The ability to choose between these two methods makes thermal label printers versatile and efficient, offering businesses the right solution for any labelling need.
