(a) Notice under this chapter shall be in writing unless oral notice is reasonable under the circumstances.

(b) Notice may be communicated in person; by telephone, telegraph, teletype, or other form of wire or wireless communication; or by mail or private carrier. If these forms of personal notice are likely to prove impracticable in particular cases, notice may in addition be communicated by a newspaper of general circulation in the area where published or by radio, television, or other form of public broadcast communication.

(c) Written notice by a domestic or foreign corporation to its members, if in a comprehensible form, is effective when mailed, if mailed with first-class postage prepaid and correctly addressed to the member's address shown in the corporation's current record of members. If the corporation has more than 500 members of record entitled to vote at a meeting, it may utilize a class of mail other than first class if the notice of the meeting is mailed, with adequate postage prepaid, not less than 30 days before the date of the meeting.

(d) Written notice to a domestic or foreign corporation (authorized to transact business in this state) may be addressed to its registered agent at its registered office or to the corporation or its secretary at its principal office shown in its most recent annual registration or, in the case of a foreign corporation that has not yet delivered an annual registration, in its application for a certificate of authority.

(e) Except as provided in subsection (c) of this Code section or in the articles of incorporation or bylaws, written notice, if in a comprehensible form, is effective at the earliest of the following:

(1) When received or when delivered, properly addressed, to the addressee's last known principal place of business or residence;

(2) Five days after its deposit in the mail, as evidenced by the postmark, if mailed with first-class postage prepaid and correctly addressed; or

(3) On the date shown on the return receipt, if sent by registered or certified mail or statutory overnight delivery, return receipt requested, and the receipt is signed by or on behalf of the addressee.

(f) Oral notice is effective when communicated if communicated in a comprehensible manner.

(g) In calculating time periods for notice under this chapter, when a period of time measured in days, weeks, months, years, or other measurement of time is prescribed for the exercise of any privilege or the discharge of any duty, the first day shall not be counted but the last day shall be counted.

(h) If this chapter prescribes notice requirements for particular circumstances, those requirements govern. If articles of incorporation or bylaws prescribe notice requirements, not inconsistent with this Code section or other provisions of this chapter, those requirements govern.
