# ManifestBench > Free carton manifest check in your browser. Scan carton, pallet or serial IDs with a phone or scanner and see what is missing. No account needed. Import a UTF-8 CSV list of distinct carton, pallet or serial IDs, choose the ID and description columns in the preview and confirm that each row is one distinct ID. Scan each label with a phone camera, a keyboard barcode scanner or by typing. A listed ID shows as Seen in this check, a second scan of it as Already seen and anything not on the list as Unexpected ID. Review the missing IDs at any point, correct a mistaken observation with a reason, finish the check to freeze a summary and reopen it with a reason. Download a CSV of every observation and missing ID, an A4 PDF report or a portable project backup. Keep the check in this tab, save it on this device or prepare the tool for offline use. ## Pages - [ManifestBench carton manifest check tool](https://manifestbench.smartfact.ai/app/): Free carton manifest check in your browser.
