[comp.dcom.telecom] Help Please Chicago Local Calling

Can someone in the Chicago area please post the cities that will be
included in the 708 area code?

[Moderator's Note: Mercy! All two hundred villages and towns in
northern Illinois?  I haven't the nerve to ask David Tamkin to type in
such a list. The general rule of thumb would be this: Chicago, zip
code 606xx, will be in 312. All other towns in the 600-601-602 zip codes
will be 708. Take any old area code directory you have now. If the
listing for a place in northern Illinois says 815, leave it alone. If
it says 312 and is *not* Chicago, change it to 708. Some 604xx zip
codes will also be in 708, although many are presently in 815.

If someone wants to enter all the 'parks', i.e. Park Ridge, Park
Forest, Forest Park, Oak Park, more; and all the variations on
Chicago, i.e. Chicago Heights, North Chicago, West Chicago, (but not
South Chicago! that *is* part of the city proper); all the 'Forests'
including the two above, also Lake Forest, more, I'll be glad to post
it here. Remember, if it is not "Chicago" -- no more, no less, with a
606xx zip code, and it isn't 815, then it is 708.  Chicago central
offices are usually identified as Chicago-office.name.  PT]

606xx zipcodes pick up some suburban points; for example, what area
code is Cicero going to be in?

602xx and 603xx zipcodes will be in 708.  600xx, 601xx, 604xx, and
605xx zipcodes will, except for those now in 815, be in 708.  (This
contradicts part of what was just sent out by the moderator.  Try
looking at Crystal Lake, IL 60014, using prefix 815-459.)

[Moderator's Note: Carl raises good points. Cicero, IL uses the
Chicago Post Office. It will be in 708 *mostly*, but there will be a
few boundary line 'discrepancies' ala Harwood Heights. The 600xx zip
codes serve far north points, and only a few exceptions in small towns
will be far enough west to be in 815 instead of 708. Speaking of
Crystal Lake, the (old) 312/815 boundary in that relatively secluded
far northwest area was always sort of ragged also. Fox Lake 312 [708]
- 587 has lots of 815 phones in the area, depending on where you are
as you go around the shore of the lake, or down the highway to Crystal
Lake.  PT]

 ... Except for some suburbs such as Niles, which border on the city
of Chicago and are served by the Chicago post office (606xx), but are
in area code 708.
