How to Pack and Send a Parcel With Royal Mail: A Reusable Step-by-Step Guide

Overview

Sending a parcel is straightforward when the preparation is treated as a series of small checks rather than a single trip to the Post Office. The parcel needs to be strong enough for handling, easy to identify, correctly measured, and suitable for the service and destination you choose.

Start by identifying four things: what you are sending, where it is going, how quickly it needs to arrive, and whether the contents require extra protection, tracking, or compensation. These details affect the packaging, label, postage method, and whether a particular service is appropriate.

Before buying postage, measure and weigh the completely packed parcel. Packaging can change the parcel’s size and weight classification, so estimating from the item alone may lead to an incorrect service choice. The Royal Mail parcel size and weight guide and parcel weight guide can help you check the relevant measurements before you compare options.

For a quick start, use this basic sequence:

1. Confirm the destination and delivery requirements.
2. Choose a suitable box or padded envelope.
3. Wrap and cushion the contents individually.
4. Fill empty space and seal every opening securely.
5. Measure and weigh the finished parcel.
6. Prepare the address and postage label.
7. Check restrictions and any customs information required.
8. Obtain and retain proof of postage.

Checklist by scenario

For a standard domestic parcel

• Choose sound packaging: Use a rigid box for items that could be crushed and a padded envelope only for contents that can tolerate some flexing. Reuse packaging only if it is clean, dry, and free from old labels and barcodes.
• Protect the contents: Wrap fragile or separately moving items, place cushioning around them, and prevent movement inside the parcel. The contents should not press directly against the outer walls.
• Seal thoroughly: Use suitable parcel tape across the main seams and reinforce areas that may open during handling. Do not rely on string, thin household tape, or a loose lid alone.
• Measure the finished parcel: Record its dimensions and weight after sealing. Then use the Royal Mail postage calculator to compare available parcel options and delivery speeds.
• Address clearly: Put the recipient’s full name, house or building details, street, town or city, postcode, and any other relevant local information on the front. Add a return address where appropriate.
• Remove conflicting markings: Cover or remove previous addresses, barcodes, labels, and hazardous-goods markings that do not apply to the new shipment.

For a fragile or valuable item

• Choose a new or especially sturdy box with enough room for protective material.
• Wrap each component separately, particularly pieces that can strike one another.
• Use internal cushioning to stop the item moving when the parcel is gently shaken.
• Consider whether the selected service provides the tracking, handling features, or compensation level that fits the item’s importance. Do not assume that every service provides the same protection.
• Photograph the item, its packaging, and the sealed parcel for your own records, especially when sending a sale, return, or high-value possession.
• Read the current service terms before posting. The Special Delivery guide explains the types of considerations to check when a time-sensitive or higher-assurance service may be relevant.

For an international parcel

• Confirm the destination format and include the country name clearly on the final address line.
• Describe the contents accurately rather than using a vague description such as “goods” or “gift.”
• Check whether the destination requires customs information, an item value, or other details before you create the label.
• Review the current prohibited and restricted items rules for both the postal service and destination country. Restrictions can apply to ordinary-looking products, batteries, liquids, food, medicines, and other contents.
• Keep a copy of the customs information, receipt, and tracking reference.

For a return or exchange

• Follow the retailer’s instructions before choosing a postage service; a return label or designated drop-off route may already be provided.
• Include the order or returns information requested by the retailer, but avoid placing loose paperwork where it can damage the contents.
• Pack the item securely even if the original packaging is being reused.
• Keep proof of postage until the retailer confirms receipt or the return is resolved. See the Royal Mail returns guide for a checklist of label and drop-off considerations.

What to double-check

Packaging and presentation

Run your hands over the sealed parcel and inspect every seam. There should be no exposed contents, sharp edges, loose flaps, or surfaces that could catch on other items. If the parcel contains several objects, confirm that none can move freely inside. A small amount of movement can become significant during transport.

Place the address on the largest flat surface where it can be read easily. Keep the label away from folds, corners, seams, tape, and curved areas. If you print a barcode, make sure it is not blurred, creased, covered, or placed over a join in the box.

Service choice

Choose the service based on the delivery window you need, the parcel’s size and weight, the destination, and the level of tracking or compensation you want. A faster service is not automatically the best choice if the packaging, dimensions, or contents do not meet its requirements. If speed is flexible, compare options using the postage calculator rather than choosing solely by habit.

For ordinary domestic items, comparing 1st Class and 2nd Class may be useful when balancing speed and cost. The 1st Class versus 2nd Class guide provides a framework for making that comparison without treating either option as suitable for every parcel.

Restrictions and records

Check the current Royal Mail prohibited and restricted items information before posting, particularly for international shipments, unusual goods, liquids, batteries, or anything that could be considered dangerous. Rules and service conditions can change, so an old checklist should not be treated as a permanent substitute for the latest guidance.

Ask for proof of postage and keep it with the parcel details. Record the date sent, destination, service selected, tracking number if available, and photographs or receipts that may be useful later. The proof of postage guide explains why these records are worth retaining.

Common mistakes

• Using a box that is too large: Excess space encourages movement and requires more cushioning. A well-fitting box is usually easier to protect and close.
• Underestimating the packed size: The item’s measurements are not the parcel’s measurements. Measure after all packaging is in place.
• Leaving old labels visible: A previous barcode or address can confuse sorting. Remove or fully cover anything that is no longer relevant.
• Relying on a handwritten address alone: Handwriting may be acceptable in some situations, but a clear printed label is easier to read. Always follow the service’s labelling requirements.
• Putting the label on a seam: Folds and joins can prevent a barcode from scanning or cause the label to detach.
• Skipping a restrictions check: Familiar household products may still have transport restrictions. Check before sealing and paying.
• Discarding the receipt: Without proof of postage or the tracking reference, resolving a delay or dispute may be more difficult.
• Assuming collection is always available: If you want a parcel collected, check the current collection service, booking requirements, limits, and costs before relying on it. The Parcel Collect guide covers the questions to ask.

When to revisit this guide

Use this checklist whenever you send an unfamiliar parcel, but revisit the details before busy seasonal periods, when sending internationally, or when your packaging and fulfilment process changes. It is also worth checking again when Royal Mail updates its services, prices, size bands, collection process, prohibited items, label formats, or compensation terms.

Businesses that send parcels regularly should review their workflow at set intervals. Confirm that scales are accurate, packaging still protects the contents, address data is current, and staff know where to find the latest service and restrictions information. Recheck the process after changing suppliers, introducing a new product, or receiving repeated damage or delivery queries.

Before your next parcel leaves, complete this final action list:

1. Check the contents against the recipient’s order or instructions.
2. Inspect the packaging and seal every opening.
3. Measure and weigh the complete parcel.
4. Compare the service options and confirm the destination requirements.
5. Review current restrictions, especially for international or unusual items.
6. Attach a clear label and remove old markings.
7. Ask for proof of postage and save the reference with your parcel records.

Keeping this sequence close to your packing area makes each shipment more consistent and gives you a simple routine to update whenever the underlying postal rules or tools change.
