C-File Number Help

[jrd01]

Hello, in the picture below in the Oath document, is the C-File Number for my great grandfather the 7 digits at the bottom?

(Also here is the picture: https://imgur.com/a/dQ39BCD)

#2256394


and if so when inputting in USCIS, would I add a "c" before it? "C2256394"

Thank you!

Yes, the # you see at the bottom of the document is the Certificate (C-file) number.
