❓ eBay Error: Duplicate Title / Listing Identifier Already Used
eBay returns this error when:
- The option “Enable duplicate title detection” is active
- A listing identifier that has already been used is submitted
🔎 What is the Listing Identifier?
The listing identifier is a unique code automatically generated by the module and sent to eBay.
It is created based on:
- The listing title
- The destination eBay marketplace (country)
This mechanism prevents duplicate listings from being published on the same account, which is prohibited and penalized by eBay.
⚠️ When is a Listing Considered Duplicate?
A listing is considered duplicate if:
- It has already been submitted by the module
- It already exists on eBay with the same title
- It is closed or unsold but still visible in “My eBay”
Important: even closed listings are included in duplicate checks.
✅ How to Fix It
Solution 1 — Modify the Title
If you still want to publish the product, slightly modify the listing title so that eBay does not consider it a duplicate.
Solution 2 — Reset the Listing Identifier History
Alternatively, you can force the module to generate new identifiers:
- Go to the module configuration
- Locate the unique ID field
- Enter a new progressive number that has never been used before
This will cause the module to generate new identifiers for future listings.
🖼 Configuration Example
Below is an example of the section where you can modify the unique ID:
