A room number is a number assigned to a room within a building. Its purpose is to identify a particular room, and help building inhabitants locate that room. [1]
Room numbers may consist of three digits, but can be any number of digits. The room number is generally assigned with the first digit indicating the floor on which the room is located. [2] [3]
Similarly to how house numbering systems vary depending on the region, room numbering systems do too. Some numbering systems inform the floor in which the room is located, but not all.
Some places in Brazil use a system in which the floor number is followed by only one number. In this system, apartment 52 is the second apartment on the 5th floor.
In many places, the number of a room is determined by the number of the floor followed by two digits that inform the number of the room itself, even if there are fewer than 10 rooms per floor. This system is used in the United States by the University of Hawaiʻi at Mānoa for buildings with fewer than 99 rooms per floor. [4] This way, the 5th's floor 2nd apartment would be number 502.
In Sweden, floor numbers must have two digits, followed by two digits for the room number. Floor numbers start from 10 at ground level, and go down for underground floors, and up for above ground floors. [5] In Sweden, the 5th's floor 2nd apartment would be number 1502.
In Rome, Italy, some addresses explicitly mention which floor ("piano") the apartment is located at. So an address could read "piano 5, interno 2" for the second apartment in the 5th floor. [6]
Hilbert's paradox of the Grand Hotel is a thought experiment which illustrates a counterintuitive property of infinite sets. It is demonstrated that a fully occupied hotel with infinitely many rooms may still accommodate additional guests, even infinitely many of them, and this process may be repeated infinitely often. The idea was introduced by David Hilbert in a 1925 lecture "Über das Unendliche", reprinted in, and was popularized through George Gamow's 1947 book One Two Three... Infinity.
A postal code is a series of letters or digits or both, sometimes including spaces or punctuation, included in a postal address for the purpose of sorting mail.
Ancient Roman architecture adopted the external language of classical ancient Greek architecture for the purposes of the ancient Romans, but was different from Greek buildings, becoming a new architectural style. The two styles are often considered one body of classical architecture. Roman architecture flourished in the Roman Republic and to an even greater extent under the Empire, when the great majority of surviving buildings were constructed. It used new materials, particularly Roman concrete, and newer technologies such as the arch and the dome to make buildings that were typically strong and well engineered. Large numbers remain in some form across the former empire, sometimes complete and still in use today.
An apartment, flat, or unit is a self-contained housing unit that occupies part of a building, generally on a single storey. There are many names for these overall buildings. The housing tenure of apartments also varies considerably, from large-scale public housing, to owner occupancy within what is legally a condominium or leasehold, to tenants renting from a private landlord.
221B Baker Street is the London address of the fictional detective Sherlock Holmes, created by author Sir Arthur Conan Doyle. In the United Kingdom, postal addresses with a number followed by a letter may indicate a separate address within a larger, often residential building. Baker Street in the late 19th century was a high-class residential district, and Holmes's apartment would probably have been part of a Georgian terrace.
A telephone numbering plan is a type of numbering scheme used in telecommunication to assign telephone numbers to subscriber telephones or other telephony endpoints.

Telephone numbering plans are defined in each of the administrative regions of the public switched telephone network (PSTN) and in private telephone networks.
House numbering is the system of giving a unique number to each building in a street or area, with the intention of making it easier to locate a particular building. The house number is often part of a postal address. The term describes the number of any building with a mailbox, or even a vacant lot.

An address is a collection of information, presented in a mostly fixed format, used to give the location of a building, apartment, or other structure or a plot of land, generally using political boundaries and street names as references, along with other identifiers such as house or apartment numbers and organization name. Some addresses also contain special codes, such as a postal code, to make identification easier and aid in the routing of mail.
