São Paulo Transporte (SPTrans) (English:São Paulo Transport), is the name adopted on March 8, 1995 by themunicipal local government which aims to manage the public transport system with buses inSão Paulo. Until 1995, it was known asCompanhia Municipal de Transportes Coletivos, which, when translated from Portuguese to English, it is theMunicipal Public Transport Company. All bus lines are operated by concessionaires under the supervision of SPTrans, providing business planning and management of public transport. The SPTrans issues work orders for each line of operation, including setting paths, hours of operation, and necessary fleet. The fare can be made in cash or bycontactless smart card calledBilhete Único. The company also manages the bus lanes and bus terminals in the city.
Bus routes managed by SPTrans have four digits or three digits plus one letter according to the service type, and a two-digit extension number, which is10 by default.[1][2]

Regional and radial bus routes within São Paulo are composed of four numerical digits in the range0,1,2 ...9. The first digit indicates the origin of the route according to the set area. The second digit is a0 for a regional route or between1 and6 for a radial route, which indicates that the route separates from the main avenue of the region. The rightmost two digits serve as a serial number.
Inter-regional and diametrical bus routes within São Paulo are composed of three numerical digits and an alphabetic digit in the rangeA ... Z. The first two digits have the same values as the regional and radial routes. The third digit indicates the region where the route ends. The fourth digit, a letter, indicates the route taken to the destination.
Following the four digits is the two digits that serve as the extension number.
The current four-digit bus route numbering system SPTrans uses today, where the last digit is analphanumerical digit, was established in 1976, but was not fully implemented due to citywide changes that were carried out according to the development, and the management change within the São Paulo's city hall.[3]
DuringMarta Suplicy's administration, between 2001 and 2004, the city was again divided into nine operational bus areas citywide, only this time from1 to9 and there were some changes.
For example, the Santana region, in the northern zone of São Paulo, which until then was area1, is now classified as area2, but most of the lines that pass through the Santana region are still numbered where the first digit is1.
In 2003, when the Pirituba terminal (which is in area1) was created, new lines were implemented, where the first digit is an8 or a9. The last digit is an alphanumeric digit.

The current model of municipal public transport in São Paulo divides the city into nine different areas, and for eight of them (1 - Northwest,2 - North,3 - Northeast,4 - East,5 - Southeast,6 - South,7 - Southwest and8 - West) lots were established for the distribution of companies and cooperatives that will provide transport services by buses, minibuses, vans and trolleybuses. Area 9 is in theCentral Zone of São Paulo, which encompasses the entire expanded centre of São Paulo, which does not have specific lots, so there is no company that operates specifically within these limits. The lines that operate only within the limits of area9 are the responsibility of companies in areas1 to8, normally, the one closest to the point considered as the beginning of the line (a rule that has several exceptions).
