That will match if there is at least one number in the string. I think
you need something like
/\A[0-9]\z/
or
/\A\d\z/

or possibly even better you could use something like
validates_numericality_of :phone_code, :only_integer => true,
:greater_than => 0
Though I think this would allow a leading + character.

if you are going to use a regexp you might as well use
validates_format_of rather than doing it yourself
