DS-160 asks me for my Border Crossing Card number.

Hello there!

I found a lot of threads on this, but none with the actual answer.

I'm at the stage on the DS-160 where I have to fill my prior visa number. I have a BCC (Border Crossing Card), and on the form it says there's a 12 digits number on the first line of the MRZ (Machine Reading Zone) on the back of the card.

The problem is that there's no 12 digit code. There are 12 alphanumeric characters on the right of the first line. They start with MEX, but when I enter this, it says it's invalid, because it has letters. If I enter just the numbers, it also says it's invalid.

There's a checkbox that says "I don't not know", which I can check to continue with the application. But I'm not sure it's a good idea to continue like that.

Here's a BCC sample

It's for Mexican citizens

Thanks a lot for your time!

This old thread suggests people used "Do not know" without issues but I have no personal experience:

Thanks. I saw that thread, but there was no follow through. On most threads on the web is the same.

One friend told me he used the BCC number without the letters and without the starting zero, and it worked. But I don't know.
