(a) In assigning PII numbers--
(1) Use only the alpha-numeric characters, as prescribed in this subpart; and
(2) Do not use the letter ``I'' or ``O''.
(b) If department/agency procedures require other identification on the solicitation, contract, or other related instrument forms, enter it in such a location so as to separate it clearly from the PII number.
(c) Enter the basic PII number, including Federal supply contract numbers and any supplementary numbers, in the spaces provided on the solicitation, contract, or related instrument forms. Separate the major elements by dashes, e.g., N00023-90-D-0009 (not necessary in electronic transmission). If there is no space provided on the form, enter the number in the upper right corner of the form and identify what it is (e.g., Supplementary Number N00023-90-F-0120).
