The Council of Architecture (COA) is the statutory body under the Architects Act 1972 that maintains the Roll of Architects — only persons listed in this Roll are entitled to use the title 'Architect' and submit drawings to municipal authorities. Each Registered Architect carries the suffix CA / <six-digit> after their name. State municipal corporations, colleges teaching architecture and clients verify a person's RA status before relying on signed design submissions. The COA Roll lists qualification, university, year of registration and any current suspension. Foreign architects practising in India must additionally register on the Roll under reciprocity provisions.
