Thanks - next time I'm in Embarq territory I might use those
Sadly, they've changed the ANAC here in Contel/GTE/VZ territory. It used to be 211. But now 211 and most of the N11 codes are assigned. 211, 411, 511, 711 and of course 911 are now assigned. 311 will soon be assigned (non-emergency version of 911), as will 811 (Miss Utility). 611 used to be repair service in old C&P/BA/VZ territory, but they've moved that to a 800 number.
Just haven't found out what the new ANAC is. I think its a 7 digit number now.
