Serial number on SE?

[Roy]

Howdy!
Received my first PRS, a A55e, yesterday. On initial inspection I could not find a serial number on the guitar. Any hints on where I should be looking or is this normal on the SE?
Sweetwater included a card with a serial number which I used for registration.
Thank you!

Never mind, I found it. It’s on the made in China headstock sticker (bummer I was intending to remove that eyesore).

Hi there ,
yesterday I bought an tonare "blind", will arrive this week.

On the sticker inside stands "CC171014813" --> does that mean it´s a 2017?
