What about if you used your first and middle name with all other details different?

In this case, provided the family name/last name Is not used, then you'll be fine.

Without the last name, It's very difficult to conclusively Identify whether an account Is linked. That Is, family names are a lot more unique than first & middle names.

One thing i have never understood though, I have used a different delivery/billing address before, some websites don't question it, others do.

As per my example above, It depends how the company's claims department Is structured and whether the representative will take the extra step to cross-check the details at hand.

For Instance, If I have enough time at work, I will check the Information. If It's close to my lunch break, I don't bother and simply process the claim.

Is there no way to know in advance if the order will get cancelled due to the billing address not being the one the card is registered to?

Orders are processed by companies Internally, so from a consumer's standpoint, It's not possible to know what happens prior to when the order Is punched Into their systems.
