[comp.dcom.telecom] Correction to NPA list posted by Michael Grant

covert@covert.DEC.COM (John R. Covert) (02/24/88)

If you are planning on keeping a copy of the area code list provided
by Michael Grant, you should make the following corrections:

903 is unassigned
706 is Northwestern Mexico
708 is assigned to Illinois effective next year (312/708 split)

To answer Michael's question about how much of Mexico is covered by 905 and 706:

905 is Mexico city only (equivalent to +52 5 XXX XXXX);
706 is Northwestern Mexico only (equivalent to +52 6X XXX XXX).

These are special codes for North American use only to support calling from
exchanges which cannot dial 011+ yet.  Other countries must dial with +52.
