Segment Reporting [Abstract]
Description of operating segments			The Company operates in a decentralized fashion in three principal business segments: The Old Point National Bank of Phoebus (the Bank), Old Point Trust & Financial Services, N. A. (Trust), and the Company as a separate segment (for purposes of this Note, the Parent). Revenues from the Bank's operations consist primarily of interest earned on loans and investment securities and service charges on deposit accounts. Trust's operating revenues consist principally of income from fiduciary activities. The Parent's revenues are mainly interest and dividends received from the Bank and Trust companies. The Company has no other segments.
