Why am I asked for credit card information when setting up my postage provider?

​All Stamps.com accounts that are registered through ShipStation are free of charge; however, the payment information that is required during registration is the payment method used to the purchase of postage through ShipStation. The USPS postage providers require your account to be funded in advance to purchase postage when necessary.
