Private X.25 networks don't have assigned network numbers.  The number
you're thinking of is an X.121 address.  X.121 addresses begin with a
DNIC, Data Network Identification Code.  DNICs for the United States
are passed out by either Dep't of State or the FCC, I can't remember
which.  These folks are working from allocations made by the CCITT. 
However, you can't have one, because those are only for public
networks.  Really, you don't need one, anyway.  It's only useful if you
connect to a public X.25 network.

So, you say, "but we do want to connect to a public X.25 network."  In
that case, the United States has a thing called "Shared DNICs," which was
set up by the FCC and ANSI as part of an inquiry made a couple of years ago
when we noticed that we were running out of numbers.  Under the Shared
DNIC principle, you get a range of X.25 numbers under your public network
provider DNIC.  Tough if you want to change providers.  

So, unless you have folks OUT of your X.25 network who need to make data
connections (i.e., not PAD connections) INTO your X.25 network, I wouldn't
bother.  

Now, if you were the Canadian Coast Guard, things would be different...

Another possibility for you is to grab one of the "ships at sea" DNICs,
which I've never understood what they were for, but if they apply to
anyone, they might apply to you (look in the back of X.121 to see).
