Terms of use: this site only turns the data you type into a barcode; it does not create, verify, register or store that data, and nothing is sent to any server. The content you enter and the use of the generated barcodes are solely the user's responsibility, including the right to use GTIN/EAN numbers (licensed by GS1), the accuracy of the information and compliance with applicable law. Links with dangerous schemes and typical attack patterns (scripts, SQL injection) are blocked, but this does not replace your own checks. By using the generator you accept these terms.
Preview
PDF and AI are vector files in CMYK, with black as C0 M0 Y0 K100. PNG, JPG and SVG are RGB.
Test every barcode before use. The user is solely responsible for the accuracy of the barcode.

UPC-A specification
UPC-A (Universal Product Code) is the retail standard in the United States and Canada. Technically it is an EAN-13 whose first digit is 0; that is why scanners configured for EAN-13 return a UPC-A with a leading 0.
Content: digits only — 11 data digits + 1 check digit (12 in total).
The first digit is the number system: 0, 1, 6, 7 and 8 for products; 2 for variable-weight items (in-store use); 3 for drugs (NDC); 4 for in-store/loyalty use; 5 for coupons.
Check digit: modulo 10 (weights 3 and 1), calculated if you type 11 digits.
Optional 2- or 5-digit add-on, separated by a space.
Nominal size (100%): 37.29 × 25.91 mm, module 0.33 mm. Allowed magnification: 80% to 200%.
How to use
Type the content. To create several barcodes, put one per line.
Adjust size, height, margin and colors. The preview follows every change.
Download each barcode in the format you need, or all of them as a ZIP.
In PDF, SVG and AI the size is set by the module X — the width of the narrowest bar, in millimetres. The default for this symbology is 0.33 mm, which is 100% of the GS1 nominal size (80% = 0.264 mm; 200% = 0.66 mm). PNG and JPG use the chosen pixel resolution. If your printer warns about ink spread, increase the bar width reduction.
