Upgrade to Amazon UK GDSN
Amazon is making GDSN compliance a priority for all suppliers in the UK and Europe, starting now. This isn’t just a technical update: it’s a fundamental shift in how product data is managed, validated, and shared across the entire supply chain.
GDSN is now the gold standard for supply chain and customer-facing product data, from GTINs, package hierarchy, weights, dimensions and more.
Manual processes are being phased out. Amazon is replacing time-consuming, error-prone Excel audits with automated, hands-off GDSN data feeds.
Immediate impact: vendors who don’t connect their Global Location Number (GLN) and publish via GDSN risk shipment delays, inaccurate inventory, and even product delisting.
Fulfillment accuracy is critical. Case pack errors are a major customer trust issue. GDSN data eliminates these mistakes by providing precise, standardised signals at every stage.
Syndigo is the leading commerce data pool, trusted by 18,000+ customers across 50+ countries.
Here’s what sets Syndigo apart:
With Syndigo, you’re not just compliant, you’re ahead.
Yes, as it based on the number of SKUs you’ll be listing to each Amazon market, we request you follow the steps in the form above to find out the subscription fee for your company.
GDSN stands for Global Data Synchronisation Network and makes it possible for any company, in any market, to share high-quality product information seamlessly. For more information, please visit the GS1 UK website GS1 UK | Global Data Synchronisation Network (GDSN) , or the GS1 locale from which you source your GLNs
If you’re unsure of your GLN, please contact GS1 UK (or your Local GS1 team) who issue GLNs, and they will be happy to help Contact us | GS1
No, the GLN you use must only be linked between Syndigo and Amazon
It will be B2B data, no B2C such as on-pack data, images, etc. Should you wish to publish B2C data to Amazon, please register your enquiry via amazon@syndigo.com and a member of our team will be in touch to discuss this.
All attributes listed below must be accurately populated (achieve a 100% readiness score) before you’re able to publish data to Amazon GDSN. If Amazon changes its mandatory requirements in the future, those revisions will be reflected in the Syndigo platform. We have training videos detailing how to populate each of these attributes and our support team is always on hand should you require additional help.
Our platform has validation rules in place to help with the accuracy of data, eg for packaging weight, Amazon requires this measurement in Grams. If you tried to enter the data in lbs. (pounds), the platform would highlight the error and confirm the correct measurement, before allowing you to populate and share the mandatory attribute.
Yes, you can publish in packaging hierarchies at pallet, case and base level and we have a training video specifically detailing how to do this. We will provide links to the training materials when you subscribe to the service.
If you are already Vendor Central, you should have an ID related to this supplied by Amazon. If you’re still unsure, we recommend contacting Amazon directly to find out.
Yes, if you have login credentials for an HFSS (High fat sugar and salt) account, please continue to use them. We will simply activate Amazon UK (for other Amazon European connections based on need) as a designated recipient to your account, once your contract is in place.
Yes. Once your new contract is in place, your HFSS and Amazon UK GDSN data will exist in the same account – creating one golden record for each SKU. You can set up new users who will publish exclusively to Amazon. Any admin user can set up new users via the platform, alternatively contact our support team for assistance.
No, Amazon UK are not currently set up to receive HFSS data via productDNA powered by Syndigo. Should this change, we will make all clients aware.
We have replicated the successful approach used for HFSS, creating a dedicated training video page for Amazon UK GDSN. Although you may have already viewed some of our training videos, it’s important you view those specific to Amazon UK GDSN as there are key differences.
Please contact amazon@syndigo.com and a member of our team will be happy to discuss this with you.
If you want to use Syndigo to send data to Amazon UK via GDSN, an easy configuration will be to use a secondary GLN to make the registration to the GS1 Global Registry. This secondary GLN will have to be communicated to Amazon, following the Content Authorisation steps Syndigo will provide you. We will also create a link between your current GDSN provider and Syndigo to automatically receive product information from your original source to complete data communicated to Amazon.
Of course. Please contact amazon@syndigo.com with your questions and a member of our team will be in touch.
Yes, we will structure your contract according to your needs. Please contact amazon@syndigo.com with your questions and a member of our team will be in touch.
