  • UK: Royal Mail IOSS Number and where to put it for Click & Drop

    Posted by Kevin on 14 June 2021 at 9:10 pm

    Royal Mail’s advice is to put your IOSS into the correct field. Sounds simple! But no such field currently exists for Click & Drop.

    For Royal Mail IOSS, thankfully a question was asked on the Click & Drop site which suggests Royal Mail don’t really have a solution so are looking to fudge the issue to keep parcels flowing to the EU.

    Answer from Click & Drop Customer Support:

    Note that this advice is ONLY for Royal Mail Click & Drop. If you use an alternative system for transmitting orders to Royal Mail you will need to speak to you label provider.

    “IOSS should be stored on trading names for customers who are importing files from multiple marketplaces and a different trading names stored for the different marketplaces negating the need to enter the details on each import file.

    For customers who have a direct integration into marketplaces like eBay, Amazon, NOTHS etc. and we pull the orders into Click & Drop from the channel, we will store the appropriate marketplace IOSS number and automatically apply the marketplace IOSS number on the orders for less than 150 Euros in the electronic data we pass when the end of day manifest or the label is purchased. Customers do not need to do anything different in these scenario’s the software will do the work on your behalf.”

    You should NOT display the iOSS number anywhere on the website, package, label, order, invoice or other documentation that can be seen by anyone else but the customs broker. The iOSS number can easily be abused and therefore should be treated very confidentially.

    We advice customers to never show the iOSS number anywhere, but instead use an encrypted number that shows that the seller has an iOSS number, and the real iOSS number can be requested by the person clearing the goods, in order to claim the VAT exemption upon importation.

    Agreed – but it looks like some websites and forums are sharing the IOSS number of Amazon.

    For example, I did a quick search and found Amazon IOSS numbers on

    Although I’m not sure if these are even valid or if there is a way of checking IOSS numbers like you can do with EU VAT numbers via the VIES website.
