Each number has a maximum of ten digits, consisting of 0 through 9, and
. The character “
” can be used as a wild card character (i.e., “do not
care” digit). The system scans all the ARS Leading Digit Plans
simultaneously from left to right. The scan ends as soon as the dialed
number matches a table entry. When using a wild card character, it is
important to use one in each digit position that must be scanned. For
example, to differentiate local and long distance calls with the same
leading digits: Plan 1) 1-
;
Plan 2) 1-215. Note that three wild card
digits were used to ensure that the system scanned the first four digits. A
shorter string of “
”s would send all the calls to the Plan 1 carrier.
