How to Avoid Undelivered Packages

Undelivered parcels are costly for your business and frustrating for your customers. For many eCommerce retailers, they remain one of the most persistent delivery challenges. The good news? With the right processes in place, undelivered packages can be significantly reduced.

Below, we explore the impact of failed deliveries and the practical steps you can take to avoid them.

Why Undelivered Parcels Are a Problem

The most obvious impact of an undelivered parcel is customer dissatisfaction. When an order doesn’t arrive as expected, customers may lose confidence in your brand and choose a competitor for future purchases—especially if the delivery was time-sensitive.

This issue isn’t limited to B2C. In B2B deliveries, undelivered parcels can appear unprofessional and disrupt wider operations, damaging relationships with clients and partners.
From a business perspective, failed deliveries also increase operational costs. Time spent chasing couriers, responding to customer queries and arranging redeliveries pulls teams away from day-to-day tasks. In some cases, undelivered parcels can even delay an entire supply chain.

Label Parcels Correctly

Incorrect or unclear labelling is one of the most common causes of failed deliveries.

To reduce risk:

• Always double-check that the full address is correct, including the postcode

• Confirm with the recipient if they’ve recently moved premises

• Ensure labels are clear, legible and securely attached

Using easy-to-read formatting—such as capital letters and durable, weather-resistant labels—helps couriers quickly identify the correct destination and minimises handling errors.

Use Parcel Tracking

Parcel tracking gives you full visibility of a delivery’s journey from dispatch to arrival. This transparency provides reassurance for both you and your customers, particularly for time-sensitive or high-value items.

If a delivery issue does occur, tracking data makes it easier to identify where responsibility lies and resolve the problem quickly. It also provides proof of delivery, which can be invaluable if customers raise disputes or request refunds.

Understand Customs Requirements

When sending parcels overseas, customs delays are a common cause of undelivered or late deliveries.

Before shipping internationally:

• Check local customs regulations, duties and VAT requirements

• Confirm that your goods are permitted in the destination country

• Ensure all documentation is accurate and complete

While EU shipments are generally straightforward, exporting to non-EU countries often involves additional controls. Taking the time to prepare properly can prevent parcels being held in customs and avoid unnecessary costs.

Communicate with the Recipient

Clear communication plays a key role in successful deliveries.

Make sure recipients:

• Know when their parcel is due to arrive

• Will be available to accept it, or

• Have a safe place or process for receiving deliveries if they’re unavailable

Failed delivery attempts — such as arriving when a business is closed or there’s no reception point — often result in parcels being returned to the depot. This creates extra inconvenience for the recipient and can negatively impact their overall experience.

Be Aware of Delivery Scams

If there’s an issue with a delivery, customers may be contacted by phone or email. Unfortunately, scams relating to undelivered parcels are increasingly common.

Encourage customers to:

• Check sender email addresses carefully

• Avoid clicking suspicious links

• Contact the courier or retailer directly if unsure

Staying alert helps protect both your customers and your business from security risks.

Deliver More Successfully, Every Time

By labelling parcels accurately, using reliable tracking, understanding customs requirements and communicating clearly with recipients, you can dramatically reduce the risk of undelivered packages.

Combined with a dependable delivery partner, these steps help ensure parcels arrive on time — keeping customers happy and your operations running smoothly.
