Requirements for Charity Listings

• Sellers may only list items on behalf of a registered charity if that registered charity has already provided the seller with written authorisation to collect charitable funds on their behalf.

• If the seller has valid written authorisation from a registered charity then the seller must display such an authorisation in their listing.

• If the registered charity is listing the item, the organisation’s charity number must be included in the listing.

• The seller’s listing must comply with all applicable conditions of the written authorisation.
