How to Cover Old Shipping Labels and Barcodes the Right Way (Step-by-Step Guide)

Reusing shipping boxes is a smart way to save money and reduce waste. But there’s one common mistake that can cause serious problems during delivery — not properly covering old shipping labels and barcodes.

If old barcodes or addresses are still visible, shipping carriers like USPS, UPS, or FedEx may scan the wrong information. This can lead to delays, misdeliveries, or even lost packages.

In this step-by-step guide, you’ll learn exactly how to cover old shipping labels the right way, avoid costly mistakes, and keep your packages looking clean and professional.

Why You Must Cover Old Shipping Labels Completely

Before we get into the steps, it’s important to understand why this matters.

Old shipping labels contain:

  • Barcodes that can still be scanned
  • Previous delivery addresses
  • Tracking numbers linked to old shipments

Even if you place a new label on top, any visible barcode can confuse scanners. Shipping systems often read the first scannable code they detect — not necessarily the correct one.

Common problems caused by uncovered labels:

  • Packages sent to the wrong address
  • Delivery delays
  • Returned shipments
  • Customer complaints
  • Lost orders

That’s why simply crossing out a barcode with a pen is not enough.

Step-by-Step: How to Cover Old Shipping Labels Properly

Step 1: Remove the Old Label (If Possible)

Start by trying to peel off the old shipping label. If it comes off cleanly, you’re already ahead.

However, in many cases:

  • Labels tear
  • Adhesive leaves residue
  • Paper remains stuck

If the label doesn’t come off completely, move to the next step.

Step 2: Never Use Marker or Tape Alone

A common mistake is using:

  • Permanent markers
  • Packing tape
  • Stickers that are too thin

These methods do not fully block barcodes. Scanners can still read through marker ink or reflective tape under certain conditions.

👉 Result: High risk of scanning errors.

Step 3: Use Proper Blockout Labels (Best Method)

The most effective solution is using full sheet blockout labels designed specifically to cover old information.

These labels:

  • Completely block old barcodes and text
  • Provide a clean white surface
  • Prevent scan-through issues
  • Work with both laser and inkjet printers

These are designed exactly for this purpose and are widely used by e-commerce sellers and warehouses.

Step 4: Apply the Blockout Label Smoothly

When applying the label:

  • Place it directly over the old label
  • Press from the center outward to avoid bubbles
  • Make sure edges are fully sealed

A strong adhesive ensures the label stays in place during transit.

Step 5: Print and Apply the New Shipping Label

Once the old label is fully covered:

  • Print your new shipping label
  • Place it on top of the blockout surface
  • Ensure it’s flat and clearly visible

Now your package is ready for safe and accurate delivery.

Best Practices for Clean and Professional Shipping

To avoid issues and improve efficiency, follow these tips:

✔ Always use opaque labels

Transparent or thin labels may not block old information.

✔ Avoid placing labels over uneven surfaces

Wrinkles or folds can affect barcode scanning.

✔ Keep labels flat and centered

This helps scanners read the correct code quickly.

✔ Use high-quality adhesive labels

Cheap labels may peel off during shipping.

Why Blockout Labels Are the Best Long-Term Solution

If you ship regularly, using proper blockout labels saves time and prevents costly mistakes.

Benefits include:

  • Eliminates scanning errors
  • Saves money by reusing boxes
  • Speeds up packing process
  • Improves package appearance
  • Reduces returns and delays

For businesses, this is not just a convenience — it’s a necessary part of efficient shipping operations.

Who Should Use Blockout Labels?

Blockout labels are ideal for:

  • E-commerce sellers (Shopify, Amazon, eBay, Etsy)
  • Warehouse and fulfillment centers
  • Retail stores shipping products
  • Small businesses and home offices

If you reuse packaging even occasionally, these labels quickly pay for themselves.

Common Mistakes to Avoid

Here are the biggest mistakes people make:

❌ Using markers to cross out barcodes
❌ Covering labels with clear tape
❌ Placing new labels next to old ones
❌ Leaving parts of the old barcode visible
❌ Using low-quality or thin labels

Avoiding these mistakes ensures smooth deliveries and fewer customer issues.

Final Thoughts

Knowing how to cover old shipping labels and barcodes properly can save you time, money, and frustration. While it may seem like a small step, it plays a big role in ensuring your packages reach the right destination without delays.

The safest and most professional method is using full sheet blockout labels that completely hide old information and provide a clean surface for new labels.

If you want to ship confidently, reduce errors, and maintain a professional look, investing in the right labeling solution is a smart move for any business.
