In the US, they are all individual "contractors". They call them Flex Drivers. They are similar to Uber drivers. Individually hired but are technically contractors. So Amazon does background checks on them but technically they are not Amazon employees, they are "self employed". Which is why many of them drive things like Uhaul vans for deliveries. They try to cram as many orders as they can into a van, and rush them through, to get the biggest possible payout.

It being done by a 3rd party doesn't mean that it is an established delivery company. Per https://logistics.amazon.co.uk/ :

> Drivers are independent contractors with a delivery provider.

> The programme is open to single driver owner-operators as well as larger companies.

I've certainly had deliveries come in unmarked white vans without the driver displaying any sort of company affiliation.

"Amazon Logistics" - it's just a front company

Are you sure about that because all deliveries I have had are clearly not from any of the regular companies you mention?

Is the Amazon Key service available in the UK?

No but you can give a door access code if one is available.
