A precisely locating and address confirming method is provided. The method comprises: S1, a printing carrier is divided into several areas with equal interval, and the width of each area is set to be the same with the width of a shelf article depositing unit, and a main bar code containing article depositing position information is printed in the center of each area of the printing carrier; S2, the printing carrier is disposed on the shelf in such a way that each area corresponds to each shelf article depositing unit; S3, the article depositing position information contained in the main bar code is scanned and read when the scanning beam of a manipulator happens to be superposed with the main bar code of the area corresponding to the shelf article depositing unit so as to confirm the address of the article depositing position. The present solution is suitable for an automatic access system for single book, CD, or the similar articles with small size, and the horizontal direction and/or the vertical direction of the article access position is is rapidly, precisely located and the address is confirmed.
