All Federal Agencies should provide their web site address on every form of correspondence with the public.
Currently, most agencies have their agency title, physical mail address, and phone number. It should be a "no brainer" to also list the web site address along with the other contact information, directly under the agency phone number.
By doing this, the American public will be able to immediately access the web site to find out answers to their questions, get entitlement information, and prevent some follow-ups to that agency.
This simple measure will save millions of dollars for federal agencies.
