American Express added a feature whereby cardholders can generate a virtual card number for online use when you don’t want to give your regular card number.
Go to Account Services -> Card Management -> Add or Manage Virtual Cards. I see this in my online login, but it errors out for me. YMMV.
This is in addition to what AmEx rolled out earlier this year to use a virtual card number via Google Chrome and Android devices.
