Required. Enter up to 50 letters, numbers, or other characters to identify this lease. Letters are automatically converted to upper case. You select the lease using this number throughout EZLease; all individual lease reports are printed in alphanumeric order (numbers first, then letters) by lease number. The lease number must be unique; if you enter a number already used by another lease in this file, EZLease notifies you and asks for a new lease number.
