Frequently asked questions
- Which barcode format should I choose?
- Code 128 is recommended for general modern retail, shipping, and inventory because it encodes full ASCII alphanumeric characters with high density. Code 39 is widely used in legacy automotive and defense applications.
- Will these barcodes scan with physical scanners and smartphones?
- Yes. The barcodes are generated with standard quiet zones and exact ratio bar patterns recognized by all standard laser, CCD, and smartphone camera barcode scanners.
- Can I download vector SVG barcodes for printing?
- Yes. You can download crisp vector SVGs that scale infinitely for high-DPI label printers and packaging artwork without blur.
- Can I encode letters and numbers?
- Yes. Both Code 128 and Code 39 support letters (A-Z), numbers (0-9), and common punctuation symbols (hyphens, dots, spaces, slashes).
- Is there any limit on barcode generations?
- No. You can generate unlimited barcodes for personal or commercial use free on TheToolss.
