Add or modify SKUs for eBay listings

In eBay, SKUs are referred to as "Custom Labels".  They aren't required when creating a listing, but they will need to be added wherever they are missing in order to properly sync with an inventory system.

Changing custom labels (SKUs) - One by one method

1. You must be subscribed to eBay’s Selling Manager (free service) or Selling Manager Pro to do this.
2. You can subscribe by clicking on your username in the top-left corner of the screen.
3. Click on “Account setting” and select “Subscriptions” from the left-side menu.
4. Click “Subscribe” next to “Selling Manager”
5. Once you are in Selling Manager, click the “Active” listings tab.  This will display all of your active listings.
6. Look for the “Custom Label” field.  If this field is not visible, you will need to click on “Customize” on the right hand side of the screen and enable the Custom Label column.
7. Click "Add" under the Custom Label column, enter the appropriate SKU, and click “Save”.

Changing custom labels (SKUs) - Bulk method

For bulk updating SKUs in eBay, you will need eBay's File Exchange tool.

1. You can subscribe by navigating to the Subscriptions page (step 1 from above) and clicking "Subscribe" next to File Exchange.
2. Once you are in the “File Exchange Center” click on “Create a Download Request”
3. In the download format, select File Exchange -> Revise Price and Quantity, then click "Save."
4. On the left side of the screen select “Completed Downloads” and you will be able to download a file with your eBay listings in a CSV file.
5. In this file you can adjust the “Custom Label” field to match your SKUs. Don't forget to save as a CSV when finished.
6. Navigate back to the “File Exchange Center” and select “Upload Listings and Updates," then select the file with your changes.
7. You can then select the “View Upload Results” on the left-hand side of the screen to confirm that the file was successfully uploaded (pay attention to the "% of Actions Completed" column).

Common File Exchange errors

• Make sure to save the file in CSV format.
• The ItemID column format may cause errors in the upload if the format is changed by your spreadsheet editing software (Excel tends to do this). As a precaution, we suggest changing the format to “Number" before saving changes to the CSV. You can do this by right-clicking on the column, selecting “Format Cells”, select “Number” and make sure to set the decimal places to "0" (by default in Excel, it is set to 2).
