where can I locate the K-1 Visa number

[benoy]

Please help me to locate the visa number in the passport. Is it printed in red ink on the lower right on the visa page or is it the control number on the upper right?
The number printed with red ink does not say if it is a visa number.
Any help would much be appreciated.

I used the red number (on her K-1VISA) when I filed I-485 for my wife.
