Adding valid product identifiers

Product identifiers in eBay can be broken down into 4 areas, below are a set of guidelines for adding product identifiers to help you prevent your listings from getting blocked.

Brand

  • Provide the brand name that customers are most familiar with.
  • If your item is unbranded, select ‘unbranded’.

Updates

  • If you’re using any of the following brands, you’ll be required to add a GTIN.
  • Make sure the brand name matches the model. For example:
    Brand: Apple
    Model: iPhone 5C

MPN

  • Make sure you’ve only used alphanumeric digits when using a Manufacturer Part Number (MPN).
  • Use the most specific MPN available. For example: different colours of a product should have different MPNs.
  • Make sure you’re adding your MPN to the correct field on the listing form.

Updates

  • MPN doesn’t contain words like ‘for’, ‘compatible’, ‘see description’, etc.

GTIN

  • Check you’ve added the correct number of digits.
  • Make sure you’ve only used numbers, not letters or other characters.
  • Double-check you’ve added the correct digits.

Updates

  • When creating multi-variation listings, GTIN shouldn’t be the same across all variations.

Item specifics

  • The item specific value shouldn’t be the same as the name of the data field. For example: in the Brand field, don’t enter the word ‘Brand’.
  • MPN, Brand and GTIN have different values.
