The Regiment was known as the Royal Norfolk Regiment for only twenty-four years. Initially, regiments were known by the name of their colonel, then in 1747 a numbering system was introduced and this Regiment became the 9th Foot.

The first link to Norfolk was made just under 100 years after the Regiment was formed and became The 9th (East Norfolk) Regiment . In 1881 all numbered infantry regiments were given stronger geographical links and a fixed regimental depot. Thus the Regiment became 'The Norfolk Regiment' and Britannia Barracks were built in Norwich as headquarters for recruiting, training and accommodation for the soldiers.
