How to check product IDs
- Upload or paste a feed with headers and an id column. Keep identifiers as text.
- Run the checker to identify missing IDs and IDs appearing more than once.
- Export the findings and investigate the source records before changing IDs or removing rows.
Understand the results
Use up to 10 MB and 20,000 records. The check compares submitted IDs; it does not determine which record is correct. Preserve stable identifiers where possible to avoid unintended product replacements.
