Oracle Park Seating
The interactive AT&T Park seating chart includes the row numbers for each section (just hover over the section).Note, the 100s sections typically begin with row 1 and end with row 41. On average, the 200s sections begin at row A and end at row M. In the 300s sections the first row is usually A and the last row is 18.
Oracle Park with Seat Numbers
The standard sports stadium is set up so that seat number 1 is closer to the preceding section. For example seat 1 in section "5" would be on the aisle next to section "4" and the highest seat number in section "5" would be on the aisle next to section "6". For theaters and amphitheaters (i.e. venues that don't have sections around the entire stage) seat numbers follow a different logic. Instead the lower numbered seats are typically closer to the center of the stage while higher seat numbers are further from the center of the stage.
