When I was little my grandparents gave me several gifts of small savings bonds that matured while I grew up. It was a small gift that grew over time and taught me a little about finance.
I'd like to do the same for my nieces but apparently now it's more complicated---you need SSN and other info and I'm not sure what is allowed. While I can get this info, I'm not sure it's appropriate.
In 2018, is there an equivalent investment vehicle one can give as a gift to a young relative?
