[1] After making their List A debut in the 1965 Gillette Cup the county played four matches in the competition up to the 1970.
The knock-out nature of the Gillette Cup means that in most competitions Norfolk only played one match, generally against a first-class county.
From the 2002 competition onwards the opening rounds of the tournament were held during the previous English cricket season.
As a result, Norfolk's last List A match, in the 2004 Cheltenham & Gloucester Trophy, actually took place in August 2003.
Most players also made appearances for Norfolk in the Minor Counties Championship.
