Fifa has rejected an application by Zanzibar to be granted full membership of world football's governing body.
Zanzibaris will continue to play in the colours of Tanzania
Zanzibar has been using the flag of Tanzania since its union with the former Tanganyika back in 1964.
But relations between the Zanzibar Football Association and the Football Association of Tanzania have never been rosy.
The Zanzibaris split from their mainland counterparts in August 2002 and have been actively seeking full membership of both Caf and Fifa ever since.
But at the end of a two-day executive committee meeting in Zurich, Fifa said it would continue to regard Zanzibar as an affiliate of Tanzania.
The world body said Zanzibar is "not an independent state recognised by the international community at present, nor is it likely to be in the foreseeable future."
Last year Zanzibar was welcomed as a full member of the Confederation of African Football (Caf).
But, curiously, the Indian Ocean island is not allowed to enter a national team in the African Nations Cup.
Zanzibari teams do take part in continental club competitions - the Champions League and the Confederation Cup - though.
The island competes in East Africa's Cecafa Cup as an independent member.
