Where can I find the credit card's expiration date?

I searched all over the invoice, etc. its not there, which is good.

I assumed it would come to me via email with their numbers. I receive the two numbers pieces perfectly, but neither contains an expiration date. Here is our test example.

Email 1:

lease direct this email to the Accounting department so that it may be
filed along with the online order it relates to:

Order: 5

Middle Digits: 11111111


Email 2:

Payment Method
------------------------------------------------------
Credit Card

Visa 4111XXXXXXXX1111

These rest is address information. Its seems like it should be here. Is there a third place that order information is stored?

Thanks,
