I have traditionally listed my telephone number as "(314) 362-3635".
My previous work number was accessible via an internal 5-digit suffix,
so I listed it as "(314) 36-23635".  Someone complained that that was
improper, and could cause problems for certain exchanges.  Yet another
sources suggested "+1 314 362 3635", under the vague impression that
this was an international standard encoding.

My question is: What is the most portable encoding of a USA telephone
number?  Is there a standards document that addresses this issue?

Note that the number used in the example is no longer valid for me.

[Moderator's Note: You really should not use () around the area code.
The area code part of the number, there is nothing parenthetical about
it. In other words, 123-456-7890 is the preferred way to write it. 
(123) 456-7890 is not preferred.   PAT]
