I would use <unitid> at the top level of your finding aid, in the archdesc/did.
<unitid type=”oclc” id=”[put number here]”/>
That’s pretty much exactly what unitid is for. From http://www.loc.gov/ead/tglib/elements/unitid.html: “Any alpha-numeric text string that serves as a unique reference point or control number for the described material, such as a lot number, an accession number, a classification number, or an entry number in a bibliography or catalog.”

Subject: Where in record to put OCLC #?
I'd like to start including the OCLC numbers for our collections in the finding aids. If you are including there (or something similar), how are you encoding it? So far, my best idea is a general <note>, but I feel like there must be a better option. We are already using <eadid> for our own collection numbering system.
