Who called from 6034220000

Its the Nat'l passport agency.

I get "this call cannot be completed" when I dial this number, telling me that it is not a correct number.  Does anybody know another number that is working?

It's the National Passport Center

When you call the national passport office you need to dial a 1 in front of the number. I get calls daily to my cell because people do not put a 1 in front of the number.

We have received calls from this number late at night and early in the morning, they do not leave a message! Who the heck are they?!
