The workspace
Calculate from 11 digits, validate 12, and never let the tool silently change an encoded value.
How it works
Paste 11- or 12-digit UPC values or upload CSV/Excel data.
Calculates for 11 digits, validates for 12.
Row-level validation flags digits and check digits.
Inspect the first UPC-A previews.
Export SVG, PNG, ZIP or a basic PDF.
Check digits
UPC-A uses 12 digits. The final digit is a check digit calculated from the first 11 digits. This tool can calculate the check digit for 11-digit values or validate the check digit for existing 12-digit UPC-A values.
Use cases
Use only with valid product identifiers
Print with correct quiet zones and scale
SVG export is preferred for vector workflows
Identifier requirements vary by platform
Render existing UPC values only
Barcode-image generation from existing values
Boundaries
Test data
You can use sample or random-looking UPC-A values for testing barcode rendering, scanner demos or internal mockups, but random UPC values should not be used as official retail, marketplace, Amazon, GS1, music or distribution identifiers. Official UPC/GTIN numbers must come from the proper issuing source.
Music releases. For music products, UPC/EAN/JAN codes identify a commercial release such as an album, EP, single or video. ISRC is different: it identifies individual songs or music videos. This tool only renders UPC-A barcode images from values you already provide; it does not issue music UPCs or ISRCs.
Trust & transparency
It renders UPC-A images and checks digits. It is not an issuer and not an Amazon tool.
UPC-A rendering and file generation run in your browser. Raw UPC values, GTINs, product identifiers, file names or spreadsheet contents are not sent to analytics, logs or server-side processing.
This tool creates UPC-A barcode images from values you provide. It can calculate or validate the final check digit, but it does not issue, register, license, verify or sell official UPC, GTIN, GS1, Amazon, iTunes, FNSKU, ISBN or music identifiers.
It does not create an Amazon-approved product identifier, FBA label, shipment label or FNSKU label. Marketplaces may verify product identifiers, brand ownership, catalog data or GTIN validity, and requirements vary by platform, category, brand and exemption status.

Yes, you can download a ZIP of SVG or high-resolution PNG barcodes, or export a basic PDF.
Yes, enter an 11-digit value and the tool calculates the final check digit to produce a valid 12-digit UPC-A.

No. This tool creates barcode images and can calculate or validate check digits, but it does not issue, register or license official UPC, GTIN or GS1 numbers.
Official retail product identifiers come from GS1 or your local GS1 member organization.
Pricing is set by GS1 and varies, so check GS1’s official site directly for current costs.
You can render a UPC-A barcode image from a value you already have, but this tool does not create an Amazon-approved product identifier. Check Amazon’s current product ID requirements before listing.
No. FNSKU, shipment and FBA box labels are a separate Amazon workflow. Use a Code 128/FNSKU workflow after checking Amazon’s current label requirements.
You can use sample or random-looking values for testing barcode rendering only. Random values should not be used as official retail, marketplace or GS1 identifiers.
