# PRODUCT321: Barcode ambiguous

## What this means[​](#what-this-means "直接链接到 What this means")

More than one product matches this barcode.

WCPOS cannot pick between them safely, so nothing was added. Search for the product by name, and give each product a unique barcode in the store to fix the clash.

## What to do[​](#what-to-do "直接链接到 What to do")

Check the details below before trying again. Retry after making the change above; retrying without it will fail the same way.
