Footnote call number. Reference call number?

Hello. I have found the term "footnote call number," which relates to numbers like the one at the end of this sentence.[1]

Am I wrong if I call those numbers that call endnotes "endnote call numbers"?

And am I wrong if I call those numbers that indicate references at the end of papers "reference call numbers"? Or should I call them "reference numbers" only?

Thank you.

[1] Footnote.
