Royal Mail Support

Royal Mail’s support site is a good place to start if you have a question specific to your account, or a general inquiry about the services and solutions they offer.

If your international parcel exceeds the limits above, it must be shipped via Parcelforce Worldwide. Each country has its own size and weight restrictions, which are available in the Worldwide Directory on their website.


Royal Mail offers a tool called Price Finder that allows you to estimate what a particular shipment might cost, and optionally buy postage for that service right on their or’s site. In addition, you can reference prices from the printable price guide provided by Royal Mail and Parcelforce.

Shipping Guidelines

Certain items require some special preparation and packaging attention, so Royal Mail provides a guide for wrapping and packaging specific kinds of products on their website.

Some goods are completely prohibited from being sent in the UK post, while others are allowed, but with restrictions, and international parcels have their own prohibitions and restrictions.

Shipments outside of the European Union require customs declaration forms.
