Introduction to Location (GLN)

13 August 2021

Introduction to Location (GLN)

Note: this article is ONLY for members who licensed a Global Location Number (GLN). If you licensed a Company Prefix, and want to learn more about the GLN associated with the Company Prefix, please view the Location User Guide.  

About Your Legal Entity GLN:

When you first license the GLN, you also receive a secondary GLN known as the Legal Entity GLN. This is used to consolidate all GS1 US licenses that your company holds. In GS1 US Data Hub, the Legal Entity GLN is referred to as the Top Level GLN, and it is automatically assigned as the "Parent GLN" of your Licensed GLN. Note: you also receive the Legal Entity GLN when you license a Company Prefix or GS1 US GTIN.   


How to Make Your GLN Active in GS1 US Data Hub:

After you license a GLN from GS1 US, you receive the 13-digit GLN in the "Welcome" e-mail from GS1 US. You can notify your business and trading partners about this GLN. You can also make your GLN "active" in GS1 US Data Hub, so your business and trading partners can search for and locate this GLN, to facilitate correct location identification. 

When you enter GS1 US Data Hub | Location for the first time, the Top Level GLN and your licensed GLN are automatically populated in a “Draft” state. The address information matches what was provided when the GLN was licensed. You can set the Top Level GLN as the “parent” of your licensed GLN, change the Location Name, and then make the GLNs “active” in GS1 US Data Hub. This allows them to be viewed by GS1 US Data Hub | Location View/Use subscribers. 

Learn More: For detailed steps on how to make the GLN active, read the Make Location Active Quick Start Guide. Or view the Make Your Location Active instructional module in the GS1 US University Learning Management System (sign in is required).

 

What if Your Address Changes?

If the company address associated with your GLN changes, visit myGS1US and click the “Manage Company Info” tile to change the company address in that area. You can then enter GS1 US Data Hub to change the address for this GLN.



GS1 US Data Hub Support of Company Prefix for GTIN-13s

GS1 US Data Hub Support of Company Prefix for GTIN-13s

As of May 24th, 2021, GS1 US Data Hub supports the Company Prefix for GTIN-13s that you may have licensed with GS1 US. 

When you log into GS1 US Data Hub, you’ll see that the GTIN-13 prefix is displayed on the main page, along with any other Company Prefixes and/or GS1 US GTINs you may have licensed with GS1 US. You can then generate EAN-13 barcodes for products to which you assign GTINs using that prefix. 

Any products you created previously with this Company Prefix outside of GS1 US Data Hub are NOT automatically entered into GS1 US Data Hub. You can import these products using these steps:

How to Import Your Existing GTIN-13 Products:

Step 1. From the Data Hub main page click Product, then the Import link. 

​Step 2.
Select the industry for these products from the main Import page.

Step 3.
​Click Download Import Template link and save this spreadsheet to your computer. Open this spreadsheet, and enter the products' values or copy them from another spreadsheet. Columns with green-colored headings are required. Note: all GTIN-13s must be entered as 14 digits, with a leading zero serving as a filler digit.

Step 4. Click Browse on the Import page and locate your completed spreadsheet on your computer. Click Submit. GS1 US Data Hub will process the items and add them to the system. If you have any errors, they will be listed in the Errors column.

Step 5. If you review a product detail record of any of the products you imported, you'll see that a GTIN-13 (EAN-13) is displayed, rather than the GTIN-12. And when you click "Barcode", you'll see that barcode image available is an EAN-13.

For specific details on how to import products, refer to the Working with Product Import User Guide.

View a demonstration, Company Prefix for GTIN-13s: Importing Existing Products, available on the GS1 US University Learning Management System (sign in is required).


How to Create Products with the Company Prefix for GTIN-13s:

You can also use GS1 US Data Hub to create new products using this prefix. Download the Company Prefix for GTIN-13s Quick Start Guide for quick steps. For more details about field definitions and other GS1 US Data Hub - Product functionality, view the Product Create/Manage User Guide.



About the Serial Shipping Container Code - SSCC

12 February 2021

About the Serial Shipping Container Code - SSCC

The Serial Shipping Container Code (SSCC) is an 18-digit GS1 Identification Key used to identify a logistic unit. The SSCC is different from the GTIN, as the SSCC acts as a license plate to track a shipment of logistics units through the supply chain. The GTIN uniquely identifies trade items (products and services). 

It is possible for a trade item, such as a pallet, to be a trade item AND a logistic unit, so both a GTIN and an SSCC may be used. The SSCC is encoded in the GS1-128 barcode and included on the GS1 Logistics Label (a sample is shown here), making it possible to track the logistic unit in transit, and locate this unit within a storage area or warehouse.

You cannot create the SSCC in GS1 US Data Hub. View a list of GS1 Standards Professional Barcode Image and Print Vendors to help you generate the SSCC in a GS1-128 barcode. The SSCC is typically generated out of the logistic management system, e.g. the warehouse management system. 

Please note that if you have licensed a GS1 US GTIN instead of a GS1 Company Prefix, you cannot create the SSCC.

Work with My UPC-A Barcode

8 April 2020

Work with My UPC-A Barcode

To generate a UPC-A barcode image in GS1 US Data Hub, you must first create the product detail record. When you assign a GTIN to the product, and click “Save,” the product status changes from Draft to PreMarket. The “Barcode” tab then displays. When the product is in the PreMarket status, you can print a "For Placement Only" or FPO barcode image. When the product is ready to share with the marketplace, change the status to In Use. Click the "Barcode" tab to download the barcode image or send the barcode definitions with a print vendor. 

Note: if you licensed a GS1 US GTIN, the status of your product is already In Use. To view the barcode image for a GS1 US GTIN, click the "Product" link. From the Manage Products page, click the "Description" for the product (in blue text), then click the "Barcode" tab.

View Create My Product and Generate a UPC-A Barcode for steps you can take to create a product.

Here are questions members have asked about working wit the UPC-A barcode in GS1 US Data Hub:

Q. Can I change the size of my barcode?
A. While you can change the size of your barcode to best fit your packaging, you should stay within the sizing restrictions noted below. If you are selling very small or oddly shaped products, other barcodes (besides the UPC-A) are available. However, some scanners are limited in what they can read and the choice of an alternate barcode should be researched before being pursued.  

Please contact one of the GS1 Standards Professional Barcode Image and Print Vendors to assist you with sizing changes.

Q. How big or small can I make my barcode? 
A. The size of your barcode will depend on the size of the bars themselves, which is given by the width of the narrowest black bar (this is called the X -dimension). These are defined in the 

GS1 General Specifications (GS1 symbol specification tables):

- The Minimum X-dimension for the UPC-A barcode is 0.0104 inches;
- The Maximum X-dimension for the UPC-A barcode is 0.0260 inches;

Based on the X-Dimensions sizes noted, the corresponding height of the barcode will be:

- For Minimum X-dimension (0.0104 inches), the bar height for the UPC-A barcode is 0.72 inches, and the minimum width is 1.174 inches (you can select this Minimum barcode size in GS1 US Data Hub)

- For Maximum X-dimension (0.0260 inches), the bar height for the UPC-A barcode is 1.8 inches, and the maximum width is 2.936 inches (you can select this Maximum barcode size in GS1 US Data Hub)

Note: "bar height" refers only to the bars and does not include the human readable interpretation (numbers) or drop-down bars (as highlighted in the image below). GS1 US Data Hub provides the human readable interpretation and drop-down bars in the image file you can download.

Also, "truncating" the barcode (reducing the height of a barcode relative to its length) is not recommended, as truncation inhibits the ability of a symbol to be scanned at the point-of-sale.

For assistance with resizing the barcode, please contact a  GS1 Standards Professional Barcode Image and Print Vendor.

Q. What are the dimensions of the "Target” UPC-A barcode image file that can be downloaded?
A: In GS1 US Data Hub, if you select "Target" from the Size section (the default selection), the dimensions of the UPC-A barcode image file, which includes the human readable interpretation and Quiet Zones, is approximately 1.15 inches in height and 1.58 inches in width. U.P.C. barcodes have a fixed relationship between barcode height and width, so if one dimension is modified, the other dimension must be altered by a proportional amount. For this reason, you should NOT resize or crop these barcodes.  

Q. What is the format of the barcode image file?
A. To save the barcode image file, click the "Barcode" tab, then "Preview Barcode." The Preview Barcode window opens. Click the Download button (highlighted below). GS1 US Data Hub provides the file as the PNG "Image Type." The PNG format is the only format available. If you require another format, such as EPS (or vector format), it’s recommended that you click the “Export Definition” button to export the barcode definitions and share these with a GS1 Standards Professional Barcode Image and Print Vendor, who can generate other image types.

Q. Will my UPC-A barcode scan?
A. The UPC-A barcode image generated by GS1 US Data Hub will scan as intended (when there are no image modifications made). However, brand owners must take an important step outside of GS1 US Data Hub to ensure their products are properly identified at retail point-of-sale. They must send this product/GTIN/barcode data to their trading partners. When this product data is shared with trading partners, the trading partner can then populate their databases so their point-of-sale scanners can retrieve the product data using the GTIN within the scanned barcode.

To learn more about barcode testing and sharing your product data, visit the GS1 US Test/Verify Printed Barcodes and GS1 US Share Information Electronically pages.

Also, read the Data Hub Frequently Asked Questions to learn about the benefits of enabling "product data sharing" in GS1 US Data Hub.

 

Q. How much space do I need on either side of my UPC-A barcode? 
A. The space (or Quiet Zones) to the left and right of your UPC-A barcode must be at least nine times the X-dimension. This means they must be at least 0.0936 inches for the minimum x-dimension and at least 0.234 inches for the maximum X-dimension. If packaging or label space allows, additional open space to either side of the barcode is recommended to allow for printing needs.

 

Q. How much space do I need above my UPC-A barcode? 
A. There is not a requirement for blank space above or below a UPC-A barcode.

 

Q. What colors and backgrounds can I use in my barcodes?
A. GS1 US Data Hub presents the barcode with black bar colors on a white background. If you or your print vendors decide to change the colors, try to make your barcodes with as much contrast between the bars and the background as you can. Don’t choose similar colors for both. The best color selections for bars and background are:
- Best background colors are white, followed by red and orange;
- Best bar colors are black, followed by dark blue or dark green.

 

Q. Are there barcode placement best practices I should consider?
A. Yes, here are a few:
- Do keep the barcode on a flat surface; don’t wrap a barcode;
- Do make the barcode easy to scan; don’t add multiple barcodes on a unit or case;
- Do make sure nothing sits over the barcode; don’t cover the barcode;
- For items intended for retail point-of-sale (POS), the preferred barcode placement is on the lower right quadrant of the back. Alternative placement for a barcode is the lower right quadrant of a side of the container other than the back; bottom marking is acceptable.

For more best practices, please view the GS1 US Place Barcodes on Products page. 

 

Q. Can I download multiple barcode images at one time?
A. No, but as a best practice, you can use the Manage Products screen to download each image:

- Click the In Use tab
- Click the product detail record
- Click the Barcode Tab
- Click Preview, then the Download button

Q. My products are cylinders and my barcodes are not scanning. What can I do?
A. If the angle of the curve is greater than 30 degrees,  you should orient your barcodes so that they align with the length of the tube and the symbols look like a ladder, as shown in the image below (as opposed to a picket fence). This will help prevent the extremes of the symbol to disappear around the curve (both ends cannot be visible to the scanner at the same time).
