PT] Patrick is right in a general sense, but 'the lower the box number, the longer the person has been a member' is not true in an absolute sense. MCI ID (mailbox) numbers appear to be assigned in groups. Mailboxes which are assigned in sequence may have a pattern similar to the following ... 410-0001 411-0002 412-0003 413-0004 ... 419-0010 410-0011 411-0012 etc. Additionally, there is some sort of check-digit mechanism built into mailbox numbers so that not every sequential number is used.
