I have questions about my annual invoice...

Plus icon dark blue indicates you can unfold elementMinus icon dark blue indicates you can merge elements

A PO number is missing on my invoice. What should I do?

You can easily do this via My GS1 under 'Invoice and payment'.


Can I change the contact person and/or address on my invoice?

Yes. You can change your contact person, address and other relevant information about your company via My GS1 under 'Company information'.


‍CanI get a new invoice issued?

Yes, you can. It takes place in the following two steps:

  • Log in to My GS1 and update your company information (e.g. the name of the new contact person or your new company address)
  • Then fill out our contact form and enter the invoice number of the invoice you want a new one issued for in the free text field

There is an administration fee of DKK 150.00 to have a new invoice issued.


How do I cancel my membership or stop using a GS1 service?

You can terminate your GS1 membership or stop using a GS1 service at any time. You can do so by completing this termination form.

IMPORTANT! Before you cancel your GS1 membership, it is important that you make sure that your GS1 subscription is not linked to electronic invoicing, registration of a location or anything else that you had not thought would be affected by your GS1 membership. If you are in doubt about anything, please contact us to be sure before you cancel your membership.


How long is the notice period for GS1 membership and GS1 services?

According to GS1's terms and conditions, there is a notice period of three months prior to the end of the calendar year. Your membership of GS1 and your GS1 services are paid in advance as an annual subscription and are automatically renewed at the beginning of the year.

If you wish to terminate your GS1 membership (and thus also all associated GS1 services), you must terminate your membership no later than on the 30th of September of that year. You must use the following termination form for correct termination.


How do I transfer my membership?

How do I get a login for My GS1/GS1Trade Activate?

For a login to My GS1, which is also valid for GS1Trade Activate, please contact us via our contact form.


Why is my price different from last year?

There can be several reasons why the price on your invoice is different from last year:

  • This may be because you have purchased a GS1 service where you only paid for the remaining months in the year of registration, and as part of the annual invoice pay for a full year
  • This may be because the GS1 service is tied to your usage, which has increased or decreased
  • This may have to do with the fact that the prices for membership, GS1 services and other services change continuously and are adjusted annually according to the net price index, cf. GS1's membership conditions‍

You can always find the current prices on our subscription prices page.

I have questions about GS1Trade Image

Plus icon dark blue indicates you can unfold elementMinus icon dark blue indicates you can merge elements

What types of product images will I receive?

Depending on the type of packaging, our standard image package includes up to 9 exposed packshots jpg and png from different angles and 6-8 planogram images in png.


‍Whydoes GS1 offer an image service?

GS1TradeImage is a sister service to our product database, GS1TradeSync, and because standardized photos linked to product data is a requirement in today's trade, we have chosen to kill two birds with one stone and make it possible to combine the two services.


Who has the image rights?

You have. Our professional photographers take care of all the technical stuff, and afterwards you should not think about photo credit or other rights issues.

Copyright belongs to the photographer according to Danish law


Can I upload images myself?

Yes, it is possible to upload images in GS1TradeSync yourself. However, please note that retailers only receive images from approved photographers and they choose not to use them for marketing purposes or planograms unless you become certified yourself.

Contact GS1Trade Image for more information


How do you get certified?

If you can provide professional product images yourself, it is possible to become certified in current image specifications and provide images that are automatically forwarded to data recipients.

Certification is a one-time benefit that is valid as long as specifications are met. If certification is revoked, a new certification process will be required.

What's the difference between Product Creation, Quality Assurance and Label Check?

Product creation: We create your products in GS1Trade Sync with quality control of the product.

Quality check: We make sure that your physical product matches the master data found in GS1Trade Sync and sign off with a quality stamp in GS1Trade Sync.

Label Check: We check the updated label information of your previously quality checked products.*

‍*does not require submission of physical products.


How do I get a new product quality assured?

When launching new products, your trading partners need to know selected product data before the product goes on sale. Therefore, contact your customer first to find out about requirements and deadlines.

Logistics information such as dimensions and weight ensure correct handling in warehouses, ingredients and allergens help your customers comply with legislation, and planogram images ensure the best possible in-store presentation. If you also want product images, you can use our GS1Trade Image service.


What happens to my products after a quality check has been completed?

When you book an appointment for GS1Trade Exact, you choose what to do with your products after the data quality check is complete.
‍Returns*: We will arrange returns, but you pay for the shipping yourself.

Destroy: We take care of destroying your products. Refrigerated & frozen products are always destroyed and cannot be donated/returned.

Donate: We make sure to pass on your products to charitable causes such as Mødrehjælpen and Project Homeless.

*When orders are completed, an email notification will be sent that samples are ready to be picked up. In cases where GS1Trade Exact does not hear from you within 10 business days, samples will be donated.


Do you also take product photos?

With our GS1Trade Image service, we take product images, planogram photos and environmental images.

GS1Trade Image is located at the same physical address as GS1Trade Exact, which makes it easy and convenient to let us handle the images at the same time.


How long is your processing time?

We perform the quality check within 10 business days of receipt. It is possible to order express handling, which halves the processing time. Express costs 100% on top of the selected service.

I have a question about GS1Trade Activate

Plus icon dark blue indicates you can unfold elementMinus icon dark blue indicates you can merge elements

GS1Trade Activate and GTIN

With GS1Trade Activate, you can keep track of how many GTINs from your company prefix you have used and what they have been used for.

You can also keep track of whether GTINs already in use are still active. GS1Trade Activate automatically generates the next available GTIN in accordance with the GS1 standard, and you can generate barcodes based on the GTINs you have registered in the tool.

You can also use the system to create your barcodes for products and pallets, for example.

For GTIN, it's also worth mentioning that GS1Trade Activate is connected to the GS1 Registry Platform and supports Verified by GS1.

The latter is basically a global directory of who owns the rights to a GTIN. If you fill in product information such as product text, brand name and net content, this information will also appear in the overview.

‍Readmore about Verified by GS1


GS1Trade Activate and GLN

You can also keep track of your GLNs with the GS1Trade Activate platform, so you have an overview of what your GLNs are used for. As with your GTINs, you can also update whether your GLNs are active or not.

If GS1Trade Activate sounds like something for you, please contact our Member Service to get started. We also have regular free online courses in the tool that you can sign up for.

How many GTINs/GLNs do I have left?

This is where GS1Trade Activate really can be an efficient tool. You simply log in to the system and get an overview of your prefixes, GTINs and GLNs. You can then create all the GTINs you've used, and when you need to create new GTINs, the system can automatically give you the next available GTIN based on your prefix.

I have questions about GTIN...

Plus icon dark blue indicates you can unfold elementMinus icon dark blue indicates you can merge elements

What is a GTIN?

A GTIN is a globally unique product number used to identify your online or physical products, no matter what industry or sector you represent.

Many people know the GTIN as a barcode, but technically a GTIN is the number found under the barcode symbol itself.

To create GTINs for your products, you need to purchase a GS1ID subscription in My GS1. After making your purchase, you will receive a unique company prefix with which you can create GTINs and other identification numbers.


Are GTINs and barcodes the same thing?

A GTIN is the number below a barcode, so technically a GTIN is not a whole barcode, but only a part of it.

However, many of our members use the term GTIN when referring to barcodes. For this reason we often also use the term GTIN on our website when referring to barcodes to avoid confusion.


How many GTINs do I need?

On My GS1 you can choose a variety of packages that contain different numbers of identification numbers. How many you need depends on how many products you have.

Read more about GTINs


When do I need to change GTINs?

A product needs a new GTIN when:

- Change of functionality or recipe, e.g. ingredients

- Change in net content

- Change of dimensions or gross weight by more than 20%

- Addition or deletion of certification mark, e.g. kosher or CE

- Change of primary brand, i.e. the brand known to the consumer

- A time-bound or promotional product

- Change the number of units in the package/box

- Changing a predefined combination, for example in a package of two or more consumer units that are combined and sold as one consumer unit

- Modification of a price printed on the packaging

- Launching a brand new product

What do I do if my company goes through a merger, acquisition or sale?

To avoid using barcodes you no longer subscribe to or using someone else's company prefix, keep the following in mind when your company constellation changes:

When merging

Transfer prefixes to the company that will continue to exist if the products are to continue with the same barcode numbers.

Download a transfer form

Acquisition of parts of a company, e.g. purchase of a brand

Prefixes used on the covered brands must be transferred from the selling company to the buying company. If this is not possible, new barcodes must be assigned and labeled, which the buying company is entitled to use. Note that only the entire prefix can be transferred, not individual GTINs.

Download a handover form

Sale of a business

If a company is sold, the buyer must either take over the prefix from the seller (and thus take over the subscription with GS1 Denmark), or relabel the products with new barcodes. You can order your own prefix for barcodes on My GS1.

I have questions about GLN...

How do I get a GLN location number?

You receive one GLN as part of your GS1 membership. Not a member or want to purchase more GLNs? Then you can buy them on My GS1 with a GS1ID subscription.

Go to My GS1

What is a GLN location number?

With a Global Location Number (GLN), you can uniquely and uniquely identify physical, functional, legal, or digital entities. That is, a sender, recipient, buyer, seller, supplier, manufacturer, place of delivery, place of payment, store, internal department, etc. Yes, even a specific shelf can have a GLN to identify this particular physical device.

GLNs are used to identify the WHO and WHERE in various relations involving trade or exchange of information. WHO are legal and functional entities, WHERE are physical and operational (digital) locations.

When you as a public or private company acquire a GLN, it is to get a unique electronic address associated with a number that contains information about where and how an electronic invoice should be delivered. In principle, you buy a unique electronic mailbox, which itself acknowledges the sender for receiving documents.


What is the structure of a GLN?

A GLN is structured with a fixed length of 13 digits. A GLN issued by GS1 Denmark starts with the number structure 57.


Can I use GLN in a barcode?

Yes, a GLN can be used in a barcode to identify a physical delivery address, or to provide relevant delivery or billing information.


Do I need GLN to use other GS1 services?

You must be in possession of a GLN if you connect to GS1Trade Sync and GS1Trade Transact.


Can I transfer a GLN if a location closes or changes?

If the location of a physical location changes and GLN does not change, deliveries will go to the "old" address that exists.

It is therefore important that you as soon as possible inform trading partners of a new GLN or changes associated with a GLN.

Please note that there are different rules for when to change the GLN depending on what the number is used for - legal, functional, physical or digital locations. Contact our advisors if you are unsure which category you belong to.

Plus icon dark blue indicates you can unfold elementMinus icon dark blue indicates you can merge elements
