13 GCA § 9407.2: Consecutive File Numbers.

Should the filing officer choose to record rather than file all financing statements and related papers, he shall mark each financing statement with a consecutive file number. All other related papers affecting such financing statement shall thereafter bear the same file number. He shall index the same under the name of the debtor (or assignor or seller) in a separate index or in his general index, and under the file number of the original statement.
