Certificate of citizenship.. Help entering numbers for 129f

[Milz 0]

I'm about ready to ship my packet out but there's one thing that's bothering me.

Since I had thought I lost my certificate of citizenship, I went through infopass to request my certificate # and A#.

The lady gave me:

certificate # 01xxxxxx (8 digits beginning with a 01)

Alien # A- 02x xxx xxx (9 digit number after the A, beginning in 0)

Now I recently found my citizenship certificate (original) and I'm seeing that first of all the certificate number looks like this : A1xxxxxxx (A1 followed by 6 numbers, total of 8 digits). it is the same number except that the first digit is 0 instead of A.

The Alien # is A2X XXX XXX . again it begins in A as apposed to 0 that the lady gave me.

Is the A interchangeable with 0 or did the lady make a mistake somehow?

Please help.

They are the same. When entering the A# for things on the USCIS site(such as e-verify and paying ELIS fee), they state if that it is less then 9 digits, then insert the 0 at the beginning after the A.
