* NANPA adopted the planning letter numbering system in July, 1996. Most earlier notifications were published as Bellcore Information Letters, numbered as IL-yy-mm-nnn, where yy is the year of publication, mm is the month, and nnn is a sequential number assigned to letters published during that month.
