What did IBM use as my License Key Center account ID?
For orders placed with IBM since October, 2003, your License Key Center account ID will be your IBM site ID. Each time you place an order against the same site ID, the license keys for that order will flow into the corresponding License Key Center account. For orders placed with Rational prior to October, 2003, your License Key Center account ID will be the Rational account number given to you on the Rational License Key Certificate shipped with your order.
