Sending important mail to CEDEX address in France

AHAR

Hi,
I figured this forum may have some experts on sending stuff abroad
I need to send some original hotel receipts to Air France/KLM in order to be reimbursed my expenditure whilst delayed by the volcano in April.
It's a French CEDEX address which sounds like their equivalent to a PO Box?
Can Royal Mail Airsure or International Signed For be used to send to this type of address?
Is it possible to declare that these bits of paper are worth the value of my reimbursement claim? (~£450) If they go missing I won't get the money...
Thanks

Y'know AHAR, I'd ask at the post office, for £450 I wouldn't take any chances.:cool:

Will do. Didn't want to make a wasted journey though if those CEDEX addresses can't accept that kind of mail.

CEDEX isn't the same as a PO box, it's a specific postcode allocated to an organisation that receives a lot of post.

In my experience, a CEDEX post code will also have a full street address - so it should get through

This is the address:
KLM Customer Care Center
TSA 21235
75564 Paris
Cedex 12
France

I'll see what they say at the post office this afternoon.
