Phone numbers I'm pretty sure about. It got joked about on Seinfeld https://www.youtube.com/watch?v=WgfaYKoQxzQ https://www.youtube.com/watch?v=WgfaYKoQxzQ Wikipedia claims that >Until 2004, RadioShack routinely asked for the name and address of purchasers so they could be added to mailing lists. Name and mailing address were requested for special orders (RadioShack Unlimited parts and accessories, Direc2U items not stocked locally), returns, check payments, RadioShack Answers Plus credit card applications, service plan purchases and carrier activations of cellular telephones. But that claim isn't sourced.
