[1] Due to a law by the regime of the Colonels which ruled Greece since April 1967, athletic clubs that were based in the same city were forced to merge with each other.

In 2003 A.C. Chalkis returned to the national championships after seven years, participating in the 2003–04 season of Gamma Ethniki and finishing 11th.

[9] Although having finished in a safe mid-table position, the team was in a financial turmoil; the entire squad was released [10] and negotiations with potential investors were unsuccessful.

[11] After a planned merger with local club Doxa Prokopiou was not implemented, Chalkida decided to pull out of every championship, remain inactive for a year and re-appear at the local Evia Football Club Association leagues for the 2005–06 season.

[13] The club also won the Evia Amateur Cup six times and finished as runners-up once, with their last victory being in 2012.
