ISO 3166-1 already defines alpha-3 and numeric code elements, as well as
alpha-2.
ISO 3166/MA has added approximately one code element per year on average
since the breakup of the Soviet Union. There are approximately 336
unassigned alpha-2 code elements, and if any of the assigned ones is
withdrawn, it can be recycled in 50 years.

Adapting to this challenge, if and when it arises, should be child's
play for the DNS, which has recently introduced TLDs like
".சிங்கப்பூர்" (or ".xn--clchc0ea0b2g2a9gcd" if
one prefers).

UN M.49 numeric code elements (equivalent to ISO 3166-1) are assigned
alphabetically by English country name, or as close as possible, with
some exceptions related to historical names. There are no allocations by
geographical region.
