[4][5] According to the Jamaica Football Federation, Barrett earned 127 caps for his country, but this figure has not been officially acknowledged by FIFA because the JFF includes all matches, even against club sides, youth or olympic teams.
He played his final FIFA international in 2000 against Honduras in the 2000 CONCACAF Gold Cup; he came on as a substitute for midfielder Winston Griffiths as Aaron Lawrence was sent off.
Warren Barrett played a big role in 1998 Qualification,'Road To France' without conceding a goal on home soil.
On 26 July 2010, Barrett was suspended from all coaching duties by the JFF for an altercation with a match official at Jarrett Park.
He was the goalkeeping coach of the Jamaican squad that finished as runners-up in the 2015 CONCACAF Gold Cup.
