From Ammoland:

AmmoLand News has reported that the ATF has been scanning nearly one billion “Out of Business” records using optical character recognition (OCR) software. If you did not know already, out-of-business FFL’s 4473 documents from gun sales made over the duration of that business have been turned over to the ATF. These “out of business” documents include personal information, including social security numbers, addresses, height, weight, eye color, etc. The ATF claims that this database is not searchable by name. This claim is true on the surface because the ATF has disabled the field within the software, but that field can be easily re-enabled at any time with just a few clicks of a mouse.
