AnyWho.com is an online telephone directory owned by AT&T. It was founded under ownership by AT&T Corporation, and became a subsidiary of The New AT&T in November 2005. Its listings are currently provided by YELLOWPAGES.COM, a wholly owned company of AT&T that was formerly a BellSouth - AT&T joint venture. AnyWho.com was to be integrated into YELLOWPAGES.COM, however, BellSouth rejected due to issues relating to AT&T's stake in YELLOWPAGES.COM. That integration is to be likely, however, due to BellSouth's acquisition by AT&T.
