My wife applied for the 50k mile card in late June before the offer expired. Barclays Customer Security called, asked questions and then requested copies of her drivers license, social security card and utility bill. The address that they gave her didn't even include the word "Barclays" - only "Customer Security" with a PO Box in Wilmington, Delaware. I called Barclays, using the number on the back of my Miles and More card, spoke to the representative and she confirmed that it was Barclays that requested the info and they need the copies mailed - no e-mails or faxes. Did anyone else have a similar experience and do you know why they're asking for copies of sensitive info?
