Are the Lost numbers really a credit card number?

You know, if you add an extra 4 to the beginning of the Lost numbers it’s the beginning of a Chase credit card.

4 4 8 15 16 23 42 XX

Or in credit card format:

4481 5162 342XX

I can hear the conversation.

“What numbers should we use?”

“Oh – let’s use my credit card number. It’s long enough. We’ll just regroup the numbers.”

“Dude – someone might figure it out. Take off the first and last number so they can’t use it.”

“Oh. Right. Yeah. Cool – let’s do that.”
