Private donors, such as Michael and Susan Dell, are also offering contributions. The Dells will give $250 to kids under 10 who live in zip codes with a median household income under $150K, though funds are limited to 25 million children and will be distributed on a first-come basis. If not enough kids sign up, the age range will be expanded.

Additional donors may still step up, so there’s no reason not to open an account for all of your kids under 18. Some funds are limited, so enroll now and activate your accounts as soon as you receive the email confirmation, which will arrive before July 4th.
