Error:
ErrorCode:240
ShortMessage: The item cannot be listed or modified.
LongMessage: The item cannot be listed or modified. The title and/or description may contain improper words, or the listing or seller may be in violation of eBay policy.
We can’t list your item because it looks like it includes a phone number or email address. Contact info is not allowed in listings and repeated attempts to include it could lead to account restrictions. Please remove any contact info before listing your item.
Resolution
As the error outlined, having a phone number in the title or product description is no longer allowed by eBay and you would need to double check and make sure the general Title / eBay Title, general Description or eBay Custom Description wouldn't include a phone number or any other details, that are not allowed and then you can update or relist the item/s and push them to the channel.
