commissionaire
Synonym discussion
Sense: noun/1
A commissionaire is the most formal and specifically uniformed of these four roles. A doorman is the broadest term — it can refer to anyone who stands at a door, from a casual hotel employee to a nightclub security guard, and has no formal uniform requirement. A porter focuses on carrying luggage inside the building and often works behind the scenes rather than greeting guests at the entrance. A concierge works at a desk inside the lobby and handles dinner reservations, show tickets, and tourist directions — they rarely open doors. A bellboy (or bellhop in American English) carries bags to guest rooms. All four overlap in hotels, but only the commissionaire is defined by his station at the front door and his formal uniform. Example: 'The commissionaire greeted us warmly at the entrance, while the concierge inside helped us book a tour for the next day.'

Etymology
Borrowed from French 'commissionnaire', meaning an agent or messenger, which itself comes from 'commission' (the authority to act for someone). The word entered English in the 18th century, originally referring to a person who ran errands or acted as a messenger. Over time it became associated specifically with uniformed attendants at the entrances of hotels and theatres, especially in Britain.
