Avoid Shipping Delays: The Best Way to Attach Shipping Labels

Shipping delays can’t only cause inconvenience to customers; they can cripple a business. A single delayed package can spiral into negative reviews, refund requests, and lost customer trust. While weather disruptions and courier inefficiencies are often blamed, one surprisingly preventable cause goes unnoticed- improper shipping label attachment.

Labelling errors might seem minor, but they have major consequences. Poor label placement can lead to failed barcode scans, lost packages, and costly delays. The good news? These mistakes are easy to prevent. By following the best practices for attaching shipping labels, you can significantly reduce these risks and ensure seamless deliveries.

In this blog, we’ll break down the most common shipping label errors, where you should never place a label, and how to fix these issues before they cost you money- and customers.

Where You Should Not Paste Labels

Attaching a shipping label might seem like a simple task, but improper placement can create significant delays. A misplaced label can lead to failed barcode scans, sorting errors, package reroutes, or even lost shipments. To ensure a smooth delivery process, avoid placing labels in the following problematic areas:

Over Seams or Edges

Placing a label over a box seam might seem convenient, but it can lead to barcode distortion when the box is handled, opened, or compressed. If the box bends or flexes, the label may tear, wrinkle, or become unreadable. Shipping couriers rely on smooth, intact barcodes for scanning- if the scanner can’t read it, your package may be delayed or misrouted.

Best Practice: Always place labels on a flat, continuous surface where they won’t be compromised by package movement or handling.

On Corners or Curved Surfaces

Labels that wrap around the edges or corners of a package become difficult for automated scanners to read. A barcode that stretches over a curved surface may get cut off or distorted, preventing proper scanning. This can result in the package being flagged for manual processing, adding delays and potential misrouting.

Best Practice: Keep labels fully visible and applied to the largest, flattest part of the package to avoid issues.

On Wrinkled, Textured, or Uneven Surfaces

If a label is applied to a rough, uneven, or textured surface, it may not adhere properly. This can lead to peeling, air bubbles, or wrinkles, which obscure important tracking details. Additionally, labels on wrinkled packaging film or poly mailers might shift or crumple, making barcodes unreadable.

Best Practice: Before applying a label, smooth out the surface of the package and press the label firmly to ensure a solid attachment.

On Packing Tape

Many businesses mistakenly apply shipping labels directly over packing tape, thinking it provides extra security. However, glossy or reflective tape surfaces can interfere with barcode scanning. Additionally, if the tape starts to peel, the label can come off with it, leading to a lost or untraceable shipment.

Best Practice: Stick labels directly onto the box or mailer itself, not over-tape. If extra protection is needed, cover the label with a single layer of matte, non-reflective tape, ensuring it doesn’t cause glare.

In a Hidden or Obscured Area

Placing a shipping label on the bottom of the package, under flaps, or in an area that gets covered during stacking can cause serious delays. If a warehouse worker or courier doesn’t immediately see the label, your package may sit untouched or be mistakenly sent to the wrong location.

Best Practice: Position labels on the top-facing surface of the package in a clear, visible area where they won’t be covered during transit or storage.

On a Previously Used Label

Reusing boxes is a great sustainability practice, but failing to completely remove or cover old shipping labels can confuse automated systems. If scanners pick up an old barcode instead of a new one, your package might end up at the wrong destination.

Best Practice: Remove all previous labels before applying a new one. If removal isn’t possible, completely cover old barcodes with a blank label or opaque tape to prevent misreads.

Top Labelling Errors and How to Correct Them

Mistakes with shipping labels can lead to unnecessary costs and shipping complications. Here are some of the most common errors and how to avoid them:

Misaligned or Wrinkled Labels

A label that is not applied smoothly can be difficult to scan, leading to processing delays. Always apply the label to a flat, clean, and dry surface, smoothing it out to remove any bubbles or wrinkles.

Using Low-Quality Printouts

Faded, smudged, or poorly printed barcodes can be unreadable, causing packages to be held up or rerouted. Use a high-quality laser or thermal printer to ensure clear, smudge-proof printing. Always verify that barcodes are fully legible before shipping.

Incorrect Label Size

Some businesses use labels that are too small or improperly formatted, making scanning difficult. Follow courier guidelines for label dimensions. Standard shipping labels should be at least 4×6 inches for optimal readability.

Placing a Label Over an Old One

Recycling old boxes is great for sustainability, but failing to remove old labels can cause confusion for automated sorting systems. Always remove or completely cover previous labels to avoid misrouting.

Failing to Secure Labels Properly

Labels that are loosely attached can peel off, leading to lost shipments. Use adhesive labels rather than taping over paper printouts. If tape is necessary, use clear tape over the entire label to prevent peeling.

Common Label Errors: A Guide to Avoiding Costly Mistakes

Shipping labels contain critical information for package tracking and delivery. Errors on these labels can be costly, leading to lost packages, re-shipments, and unhappy customers. Here’s how to avoid the most frequent mistakes:

Incorrect Address Information

Mislabeled addresses can result in returned shipments, additional shipping fees, and customer dissatisfaction. To avoid this, always double-check the following before printing and attaching the label:

• Ensure the street numbers and names are accurate and match the recipient’s details.
• Verify the pin codes to prevent misrouting of the packages.
• Include the apartment or house number if applicable, as missing unit numbers often cause delivery failures.

Missing or Incorrect Weight and Dimensions

Couriers use weight and size information to calculate shipping costs. Entering incorrect dimensions can lead to unexpected fees or rejected shipments. Always weigh and measure packages accurately before generating labels.

Failing to Include a Return Address

Without a return address, undelivered packages may be lost indefinitely. Always include a return address to ensure packages can be returned to origin, if needed.

Using Non-Compliant Labels

Each courier has specific requirements for label placement and formatting. Ensure your labels meet these standards to avoid rejection at drop-off points.

Forgetting to Test Barcode Scannability

If a barcode cannot be scanned, package tracking is disrupted, increasing the risk of loss. Always test barcodes before shipping by scanning them with a smartphone or barcode scanner.
