Using product identifiers
Using product identifiers
You must include product identifiers when listing in certain eBay categories. These identifiers help buyers find exactly what they're looking for as well as making it easier for search engines to match your items to appropriate queries. Even when they're not mandatory, including product identifiers in your listings can help you attract more buyers.

Product identifiers include the brand as well as unique codes typically found on labels or bar codes. They serve a number of functions, including helping retailers keep track of and manage their stock.
Key product identifiers on eBay.co.uk are:
- Global Trade Item Number (GTIN): A series of numbers assigned to most retail products and includes European Article Numbers (EANs) and International Standard Book Numbers (ISBNs). Visit gs1.org for more about GTINs.
- Manufacturer Part Number (MPN): A number that, in combination with the brand, uniquely identifies a product. Manufacturers use these numbers to manage their product inventory and product lines.
Using product identifiers helps buyers find your items faster by raising the visibility of your listings.
- New listings
- Listings you’ve manually relisted
- Listings where you’ve revised the title, category, GTIN, item specifics or item condition. If you revise other fields, such as price, you don’t need to add product identifiers.
- Listings with variations (from 31 January 2016)
- Good 'Til Cancelled listings (from 29 February 2016)
We encourage you to add product identifiers as soon as possible where applicable so that all your listings remain competitive in search. This supports an even better shopping experience as we move toward a more product-centric shopping experience.
If you sell unbranded items, or items that don’t have product identifiers, you can select Does not apply in order to complete your listing. However, do remember that your listing won't receive the SEO benefits if you select Does not apply. We recommend that you always add product identifiers when they are available.
In My eBay > Selling and in our bulk edit and relist tool, we highlight which of your listings are missing product identifiers. We’ll also highlight relevant product identifiers in the Sell Your Item form and provide tips on how to complete your listings.
