Is this table built from the same spec, and just encodes exceptions ( ie. MCCs which may have 2 or 3 digits )?

374 is Trinidad & Tobago, which has both 2-digit and 3-digit MNCs in the spec ( 2 are 3-digit, 1 is 2-digit )
714 is Panama, which also has mixed MNC lengths, mostly 2-digit ( the reverse of T&T )
405 is one of India's MCCs, however in the spec ( ITU-T E.212 ) all of India's MCCs have 2-digit MNCs.  Am I missing something?

Also, in the spec, Canada's MNC (302) is mixed.
