Alien number is available only for Persons applied for Adjustment of status [I-485] , GC holders and Citizens only. Alien number will be also available in I-140 approval notice of the particular person. The persons who are in non immigrant visas, then they have to provide SSN or Tax ID number [IRS number] for verification.
Mark Twain rather famously said "Persons attempting to find a motive in this narrative will be prosecuted; persons attempting to find a moral in it will be banished; persons attempting to find a plot in it will be shot." Technically he wrote that about the "sequel" (Huckleberry Finn), not about Tom Sawyer, but I think the basic idea holds.
