The idea
Numeric codes are usually the sum of positions, sometimes with a constant added. Verify against both examples before applying.
Shortcut. Once the sum rule checks out, the units digit decides: P (16) + I (9) + G (7) has units 6 + 9 + 7 = 22 → 2, and only 32 ends in 2.
Common trap. "31" — taking P as the 15th letter (that is O); P is the 16th, and 16 + 9 + 7 = 32.
