In the Washington D.C. area, the CNA Bureaus do not require any identification
from the caller; you just give them the number and they give you the data. 
Strangely the numbers are not local calls to the D.C. calling area though,
being down in West Virginia. The Non-Pub Bureau seems to work the same way,
allowing you to do DA lookup on Non-Published numbers. The only thing that 
has changes in either of these services in years is that the Bell breakup
caused the Bureaus to be broken up into different calling numbers for each
area, rather than a single number per company (i.e. C&P).

There was a list made available long before the breakup that listed all of the
numbers for the entire CONUS. These changed with the breakup, but our friend
Ma Bell made sure that most of the numbers had Intercept on them giving the
new numbers..... They even screw themselves up, so don't be so hard on them
when they screw you up too.....
