GS1 DataBar & DataBar Online

The GS1 DataBar is a stacked omnidirectional barcode created by the global standards organization, GS1. The GS1 DataBar was designed to fit on small loose produce items that are not large enough to accommodate a UPC barcode. The barcode is printed on a PLU sticker and supplemented by the 4- or 5-digit PLU code as the human readable portion. The PLU code can be used as a back up as it can be entered manually at the point of sale if the barcode does not scan. It is important to reiterate that the GS1 DataBar is used for loose produce and not packaged produce (e.g. bags or clamshells) or case-level identification. If a larger individual produce item has a UPC barcode (e.g., watermelon), it does not need to have a separate GS1 DataBar created.

The GS1 DataBar is encoded with a 14-digit Global Trade Item Number or GTIN. It enables the capture of brand-owner identification for loose produce instead of only the category of the item via the PLU code. Although it will identify the brand owner, it does not contain information to assist with full traceability efforts (i.e., batch/lot number or pack date).

Benefits of GS1 DataBar

The implementation of GS1 DataBar barcodes on PLU stickers has many advantages to both retailers and suppliers.

• Improved category management
• Increased checkout speed
• Improved inventory accuracy
• Enhanced product quality management efforts
• More products automatically and accurately identified at point of sale
• Shrink control via front-end accuracy
• Facilitated self-checkout

The PLU sticker with the 4- or 5-digit PLU code alone provides information required to charge the correct price at the point of sale but provides limited information for category management.

Retailers who successfully implement the GS1 DataBar barcode for scanning realize many benefits. The point-of-sale (POS) transaction time is reduced from 4 seconds to manually key the 4- or 5-digit PLU code to 1 second to scan the barcode. They are able to implement category management down to supplier and item level and can determine the sell through (retail units sold vs. purchased) by item and by supplier. This information can indicate the effectiveness of each supplier's cold chain and guide the retailer’s decision as to which suppliers they purchase from. Retailers are also able to understand sales and profits by supplier and by variety, no longer just at the item or category level.

Retailers can use the data to enhance their Computer Assisted Ordering process and, when dealing with a recall, can verify which stores scanned the recalled product and take appropriate action based on this information.

Gross margins increase due to scanning accuracy, eliminating the potential for human error that can occur when using manual PLU entry. Many cashiers memorize PLU codes or sometimes enter them incorrectly. Some do not read the PLU sticker, assuming the product is conventional when it is organic or enter the wrong PLU code. Not all red apples are Red Delicious!

Customers using the self-checkout stations report increased satisfaction with the process when GS1 DataBar scanning is enabled.

The benefits of GS1 DataBar to suppliers are discrete visibility of their product’s quality, sell through and shrink in each of their customer’s supply chains, brand differentiation and category management that facilitates collaboration with retailers and longer term planning.

Transitioning From PLU Code to GS1 DataBar

For each PLU-coded product you sell, you will need to create a corresponding 14-digit GTIN using the following steps:

1. Obtain a GS1 Company Prefix
   • Contact GS1.
     
     
2. Create your 14-digit company-specific GTIN.

GS1 Company Prefixes will rannge in length from 7 to 11 digits, depending on the company’s capacity, so item reference number lengths will also vary as indicated in the following chart.

Formatting the GTIN for DataBar

The GS1 Stacked Omnidirectional DataBar has a 14-digit data structure for the product identification number.

For the United States and Canada, the 14-digit GTIN for the GS1 DataBar is built using the GTIN-12 and includes the following components:

• Indicator Digit: Used to define the packaging hierarchy of a product. This number is always a “0” for loose or bulk items.
• GS1 Company Prefix: A number assigned by GS1 that uniquely identifies a company from any other company in the world. (The GS1 Company Prefix is the UPC Company Prefix with a preceding zero added.) Contact GS1 to obtain your Company Prefix or for more information.
• Item Reference Number: Assigned by the owner of the GS1 Company Prefix to identify the item; the length is based on the length of the prefix.
• Check Digit: The last digit which is calculated by an algorithm and serves as a “checks and balances” to ensure the preceding digits were entered correctly. To calculate the check digit, use the Check Digit Calculator.

For the Rest of the World, the 14-digit GTIN is built using the GTIN-13.

1. Begin with the Indicator Digit, which is always '0' for the GS1 DataBar for loose produce.
2. Follow with the GTIN-13 for the item.

It is not advised to assign the PLU code as the item reference number (e.g., a company having an 8-digit or 9-digit Company Prefix will not have enough digits to use a 4-digit PLU as an item reference number). The owner of the Company Prefix can assign whatever numbers they wish as the item reference number, but it is suggested that no intelligence is built into the Item Reference Numbers. Instead, start with the number '0' and continue to assign the numbers in sequence for all items in your product catalog.

It is recommended that GTINs are assigned to your items using the same granularity as the PLU code (Commodity, Variety, Size Group). As most retailers' systems are used to this level of granularity, it will make the transition much easier if each companies' GTINs equate to this level of granularity.

There are label manufacturers available to assist with the creation of the GS1 DataBar on your PLU stickers.

With the implementation of GS1 DataBar increasing, PMA created a simple data synchronization tool called DataBar Online. DataBar Online acts as a central repository for data exchange and provides a single point of contact between trading partners. The tool is designed for use by sellers of loose/bulk produce to communicate their 14-digit GTINs and corresponding PLU codes to their buyers. Buyers can then download this information into their point-of-sale systems to scan the GS1 DataBar on individual produce items rather than manually entering the PLU code to identify the product.

It is important to note that DataBar Online is used for item-level identification only (e.g., PLU-coded produce); it is not intended for package- or case-level identification.

Benefits of DataBar Online

• Provides a single source to exchange data in one consistent file format.
• Offers an automatic download feature to ensure the most accurate and complete data exchange.
• Improves checkout processes with increased accuracy and speed (from 4 seconds to 1).
• Reduces no scans or not on file scans.
• Can remedy emergency buy situations.
• Retailers can search for suppliers of a particular commodity by searching a specific PLU code.
• Suppliers are only required to enter their data once and do not need to communicate their GTINs and PLUs to various retailers directly.
• Alleviates cashiers’ doubt in scanning and automatically keying in the PLU code

Implementing DataBar Online

Buyers

Buyers can log in to DataBar Online and select individual suppliers to download or opt to download the entire database of GTINs.

Note: It is advised that buyers download the entire database to avoid omitting GTINs that have been uploaded by third-party companies. Failure to do so could result in ‘not on file’ scans and other scanning issues.

For additional implementation resources, buyers can contact PMA’s Supply Chain Efficiencies team.

Suppliers

To begin using DataBar Online, suppliers must build their 14-digit GTINs for each produce item. The first step to building item-level GTINs is to obtain a GS1 Company Prefix. (Information on how to correctly build 14-digit GTINs can found in the article, GS1 DataBar.) The second step is to assign the corresponding PLU code. PLUs for each commodity can be searched within DataBar Online. All 4-digit PLUs must begin with a three (3) or a four (4,) and all 5-digit PLUs must begin with a nine (9) to indicate an organic commodity. Detailed information for PLU codes can be found in the PLU Search section of the International Federation of Produce Standards (IFPS) website.

Retailer assigned codes cannot be used in place of valid PLU codes as these codes are assigned to different commodities by different retailers. Uploading these codes in DataBar Online could inadvertently corrupt a retailer's point-of-sale system. Retailer assigned codes must be communicated to retailers directly.

When GTIN and PLU code assignment is complete, the next step is to build an Excel comma-delimited (.csv) file with the 14-digit GTINs in the first column and the corresponding 4- or 5-digit PLU codes in the second column. This is the file used to upload the data in DataBar Online. Once the .csv file is created, the data should be verified using a text editor, such as Notepad. Note that multiple GTINs may correspond with a single PLU code. Detailed instructions on uploading data can be found in the Tutorial.

All subsequent data that is uploaded will be appended to the current data and create a running GTIN list. No data will be overwritten.

Following the initial upload, the GTINs can be updated individually as needed in the Update Online section of DataBar.

Utilizing the Data

To update individual GTINs in DataBar Online, suppliers have the option to add, revise or delete records through the Update Online feature. The Download option can also be used to verify the uploaded data.

Retailers and other buyers can download supplier data manually or use the web service option to automatically download the information. The automatic web service ensures that buyers have the most current data.

Fees

Suppliers who are PMA members pay a one-time access fee of $300. Non-member suppliers pay a one-time access fee of $1,100.
