Barcode Requirements and Troubleshooting
Cahoot requires strict adherence to barcode and product identification standards. Proper use of barcodes ensures smooth fulfillment, accurate inventory management, and error-free order processing.
Important: Each product must have one unique barcode for Cahoot fulfillment. Most scanning issues are caused by physical quality problems (size, paper type, placement), not barcode format incompatibility.
Supported Formats & Configuration
Cahoot accepts these GS1-compliant formats:
- UPC-A (12 digits)
- EAN-13 (13 digits)
- Code 128
- ISBN-13 (books)
- GTIN: Universal product identifier format
Barcode Configuration:
- Primary Barcode: One unique barcode required per product
- Alternate Barcode: One additional barcode supported
- More than two barcodes: Submit a Barcoding Work Order or create separate SKUs
Note about UPC vs. Barcode Fields: The Barcode field is used for all scanning operations. The UPC field is optional and does not impact fulfillment.
Scanner Requirements:
- Code 128 A, B, or C compatibility
- Google Chrome browser for Cahoot web application
Quick Barcode Diagnosis
Before contacting support, check these common issues:
- Size: At least 1" x 2" with white background
- Surface: Avoid glossy paper, foil, curves, or seams
- Quality: High contrast, crisp bars, no smudging or fading
- Test: Scan into a text editor (e.g., Notepad) to verify output
Physical Requirements:
- ✅ Use: Matte white paper, flat surfaces, minimum 1" x 2"
- ❌ Avoid: Glossy/foil paper, curved areas, corners, tape over barcode
Pro Tip: If a Cahoot-generated barcode scans but yours does not, the issue is physical quality, not format.
When contacting support, provide:
- Whether all units have the same issue
- Scan results from a text editor
- Clear, well-lit barcode images
- Test results using a Cahoot-generated barcode
- Scanner make/model (if Cahoot barcodes also fail)
Common Solutions
Most scanning issues are resolved by:
- Increasing barcode size
- Switching to matte white label paper
- Placing barcode on a flat surface
- Improving print clarity and contrast
For persistent issues:
- Submit a Barcoding Work Order
- Use Code 128 format for new products
- Implement supplier quality controls
Important: Inbound shipments with unscannable barcodes may be delayed 5–7 business days for rebarcoding.
Prevention & Best Practices
Before sending products to Cahoot:
- Test barcodes using your own scanner
- Scan into a text editor to confirm accuracy
- Verify physical quality meets standards
- Fix issues before shipping to avoid delays
Quality Assurance Process:
- Supplier Guidelines: Share barcode requirements with suppliers
- Sample Testing: Validate labels before full production
- Regular Audits: Verify barcode-to-SKU mapping
- GS1 Compliance: Purchase barcodes from GS1 for global uniqueness
Remember: Most barcode issues are due to physical quality, not format. Focus on size, material, and placement.
