The STP was reorganized into the Syndicat des transports d'Île-de-France (Stif) in 2000, giving the agency the ability to enter into competitive contracts with operators and more tightly control its expenses.

In 1975, as a means of simplifying the somewhat complicated fare collection across the disparate public transit systems across greater Paris, the Carte orange travel card was introduced.

[2] During the 2000s, in response to hundreds of incidents involving trackside intrusions being recorded, STIF launched a program to retrofit platform screen doors at many of its existing stations in order to minimize such occurrences and enhance safety.

[8] One year later, an consortium comprising Alstom and Bombardier Transportation were selected to supply 255 X’Trapolis Cityduplex double-deck electric multiple units to replace aging rolling stock on lines D and E of the Île-de-France network under a €3.75 billion arrangement.

[9] In June 2015, a contract valued at €20 million was awarded to Alstom Transport to develop and install an automatic train operation (ATO) system on RER A of the Réseau Express Régional network servicing Paris.

[10] During February 2017, it was announced that STIF and the public transportation company Keolis had signed contracts valued at €750 million to partner on improving the bus network serving Greater Paris.
