Best Practices for Custom Barcodes
Use Code128 for shipping—it is the standard
Print at 203+ DPI for thermal printers
Size minimum 2\×1\ (width × height) Add 0.1\ quiet zone (blank space) around barcode, Use pure black & white (no colors), Test one barcode before printing batch, Verify it scans with actual barcode scanner,
Common Barcode Generation Mistakes
Mistake 1: Wrong format for use case
Don't use EAN-13 for custom order codes. Use Code128 instead. EAN-13 is for product codes.
Mistake 2: Too-small barcode
Minimum 2"×1". Smaller barcodes often fail scanning. Use larger if possible.
Mistake 3: Not testing before bulk printing
Always print and scan 5-10 test barcodes. Verify they scan before printing 500+.
Mistake 4: Using wrong quantity of digits
UPC-A must be exactly 12 digits. EAN-13 must be exactly 13 digits. System will reject incorrect lengths.

Yes, but not recommended for tracking. Each shipment should have unique code. For testing, reusing is fine.
Q: What if I need to generate 1000 barcodes?
This tool generates one at a time. For bulk generation, use our eLabelCropper product which has batch barcode generation.
Q: Can I print these barcodes directly?
Yes. Download as PNG, insert into your label design, print normally.
Q: What barcode scanner apps work with these barcodes?
Any standard barcode scanner (hardware or smartphone app) that supports the format you used. Code128 works with all professional scanners.

Frequently asked questions
What types of barcodes can I create with this barcode generator for shipping labels?
You can create Code128, UPC-A, and EAN-13 barcodes. Code128 is ideal for shipping labels due to its high density and support for alphanumeric data, while UPC-A and EAN-13 are standard for retail products.
How do I generate a custom shipping barcode for my specific needs?
Simply input your desired data (e.g., tracking number or product code) into the generator, select the barcode type (Code128, UPC-A, or EAN-13), and customize dimensions or colors if needed. The tool will output a high-resolution barcode image ready for printing.
Can I use these barcodes for international shipping labels?
Yes, Code128 is widely used for international shipping as it supports various characters and is compatible with most global carriers. EAN-13 is also recognized internationally for retail products, making it suitable for cross-border shipments.
What is the difference between Code128, UPC-A, and EAN-13 barcodes?
Code128 is a high-density alphanumeric barcode used for logistics and shipping. UPC-A is a 12-digit numeric barcode for US retail products, while EAN-13 is a 13-digit variant used internationally. For shipping labels, Code128 is recommended for its flexibility.
Are there any size or resolution requirements for printing shipping barcodes?
For reliable scanning, ensure the barcode is at least 1.5 inches wide and has a resolution of 300 DPI or higher. The generator allows you to adjust dimensions, but avoid scaling down too much to prevent scanning errors.
