> Upon contacting the operator, users were to also communicate a "SOURCE CODE". It played no part in generating the Unlock code. It may have been a way for the distributors to claim a transaction fee. Browsing eBay, I found many with names indicative of past/present retailers. 12-BSTBY BestBuy, 24-CCITY Computer City, 22-CUSA CompUSA, 88, 11-1111, 38-EB Electronic Boutique, 44-FTRSP Future Shop (Canada), 34-EGGH Egghead Software, and 56-MCTR Media Play/ Musicland.

Why do we think that CCITY is a code for Computer City and not Circuit City?

Presumably MCTR was MicroCenter as well.
