Amazon product labels

Frequently asked questions

Does BarcodeStack generate FNSKUs?

No. Obtain the correct identifier and labeling instructions from your marketplace account. Use the marketplace-generated label when required. Do not substitute an internal seller SKU or example barcode.

How do I keep the tags from printing scaled?

Select the required stock size and printer resolution, export a preview and print at 100%. Inspect the output dimensions and encoded identifier. Use ZPL only with a compatible model and review conversion warnings.

Which stock size should FBA tags go on?

Follow the current requirements shown for your specific shipment and printer. The preset suggestions are generic artwork sizes; they are not evidence that a marketplace accepts that stock or layout.

Can I print these in bulk from a spreadsheet?

Import a local spreadsheet or paste private data, then put {{column}} placeholders in text or barcode values. Imports support up to 5,000 rows within file and cell limits; export large jobs in smaller ranges within the output limits. Use a Google Sheets link only for data already intended to be accessible to anyone with that link. Review the values and test a label before a batch.

How do I check the printed size?

Select the measured stock dimensions and your printer's actual resolution. Exported PDF dimensions follow your selection, but drivers, scaling and media feed affect the result. Print at 100% scale (Actual size), measure a sample and test-scan each barcode before a batch.
