1. Delivery without a handover
Check whether the selected service permits delivery through the letterbox. A parcel may still fail to fit or encounter an inaccessible delivery point.
Sending Letterbox-Sized Parcels from the Netherlands: What to Know
A letterbox parcel is a parcel designed to fit through a letterbox opening, so it can be delivered without a doorstep handover. Whether that works depends on the packed dimensions, the letterbox opening and the selected delivery service. Do not assume a product qualifies just because it is small.
What makes a parcel letterbox-friendly?
The binding constraint is thickness. Length and width matter, but a parcel only becomes letterbox-friendly when it can pass through the opening — so thin, flat and lightweight is the profile. Choose packaging that protects the product and stays within the selected service limits. Do not rely on compressing the parcel to make it fit.
Exact size and weight allowances differ per carrier and per country, and they change over time. In the Netherlands you will see the Dutch term brievenbuspakje; in the UK, Royal Mail uses its large letter format for the same idea. Always check the current rules of the carrier and service you use — and remember they apply to the packed parcel, including packaging.
Letterbox parcel, small parcel, mailbox parcel — the differences
These terms get mixed up constantly. Here is the practical breakdown:
- Letterbox parcels must fit through a letterbox opening. Thickness is the limit.
- Small parcels are the wider range. For Vareya, Suitable smaller parcels have combined dimensions below 900 mm and a maximum length of 600 mm. Product fit is confirmed during qualification. Important: that combined-dimensions profile describes our overall small-parcel range — it is not a letterbox limit. A parcel can comfortably sit inside the small-parcel range and still be far too thick for a letterbox. Letterbox-friendly is a stricter, thickness-driven subset of the small-parcel world. See small parcel fulfilment in Europe for the wider profile.
- Mailbox parcels / mailbox-friendly parcels — "mailbox" is mostly an American-English word for the same delivery idea, but be careful online: searching for "mailbox parcel" often brings up virtual mailbox and mail-forwarding services, which are a completely different thing. When we say mailbox-friendly, we mean letterbox-compatible.
What to check before choosing letterbox delivery
2. Service-specific prices
Compare the letterbox service with the relevant parcel service using the same destination and packed weight. Check all applicable fees rather than assuming a saving.
3. Customer requirements
Check whether tracking, a signature or a handover is important for the order. Choose the service around those requirements.
None of this means every product should be forced through the slot. Fragile items, high-value products that benefit from a handover or signature, and anything that needs protection beyond a mailer are better served as standard parcels.
The lightweight angle
Letterbox-friendly products are almost always on the light side, and lightweight products deserve a fulfilment partner who is built around them. Carrier prices step up in weight and size bands; small, light, boxable items may fit different price bands and storage arrangements. Check packing time and storage needs for the actual order mix. That is exactly the profile Vareya is set up for from Breda — we specialise in cosmetics, supplements, phone cases, accessories and other smaller parcel products. Vareya is generally best suited to brands shipping 500 or more orders per month. Product fit is confirmed during qualification.
How fulfilment handles letterbox parcels
Letterbox fulfilment is a packaging discipline as much as a shipping one. The same product can be letterbox-friendly in one mailer and a standard parcel in another — so the packing choice is made per product line, and sometimes per order. Vareya's shipping system can automatically select an appropriate carrier for each shipment, based on destination and parcel characteristics. And we agree packing instructions with you before go-live. PostNL is Vareya's main carrier for shipments within the Netherlands. DHL, Asendia, FedEx and Royal Mail remain part of the carrier network for other routes.

Frequently asked questions
Does a letterbox parcel need a signature?
By design, letterbox delivery is a no-handover service. If signature or handover matters for your product, choose a standard parcel service instead.
Why did my parcel not fit through the letterbox?
Check the actual letterbox opening and the packed parcel, including any bulge, filler or item that shifted in transit. Thickness is only one of the dimensions to check.
Can Vareya handle both letterbox and standard small parcels?
Yes. Letterbox-friendly products are part of our small-parcel profile; Product fit is confirmed during qualification.
