How to use Barcode
- 1

Practical ways to use Barcode
Internal stock labels
Use Code 128 for letters, numbers and common punctuation when your own inventory system controls the identifier.
Retail product artwork
Render an assigned UPC-A or EAN number for packaging, then verify size, contrast and scanning in the final printed design.
Outer cartons
Use ITF-14 when a trading partner or logistics specification calls for a 14-digit shipping-container code.
Choose deliberately
Make the right output
Code 128 for flexible internal IDs
It handles printable ASCII text and is a practical choice for warehouse bins, assets and order references that are not retail GTINs.
UPC-A, EAN-13 or EAN-8 for assigned retail numbers
Match the format to the identifier you have been issued. The tool can calculate a check digit, but it cannot create ownership of a number.
SVG when print quality matters
Choose SVG for packaging or label software that accepts vectors. Choose PNG only when the destination application needs a bitmap.

Frequently asked questions
Does this tool issue official UPC numbers?
No. It creates the barcode image only. Obtain and register official retail identifiers through the appropriate standards organization.
What is Code 128 best for?
Code 128 is compact and flexible, making it useful for logistics, inventory and internal labels when the receiving system supports it.
Are check digits added automatically?
For supported numeric formats, a missing check digit is calculated. A supplied check digit is validated.
How should I test a barcode?
Place it in the final artwork, print on the intended material and scan several samples with the hardware and software used in your workflow.
