The first section of line 2 was opened on October 28, 1999, from Zhongshan Park to Longyang Road. This section, which included 12 stations, totaled 16.3 kilometres (10.1 mi). A year later coinciding with the tenth anniversary of the development and opening up of Pudong, marking the official opening of the line, Zhangjiang High Technology Park was added to the eastern part of the line, adding 2.8 kilometres (1.7 mi).^[5] Four new stations, located west of the Zhongshan Park station, opened in December 2006, extending the line to Songhong Road. This section added 6.15 kilometres (3.82 mi) to the line. Four years later, in preparation for the 2010 Shanghai World Expo, the line was significantly expanded. In February, the Zhangjiang High Technology Park station was rebuilt. In addition, another eastern segment took line 2 to Guanglan Road.^[6][7][8] A month later, the line was extended westward to East Xujing, adding 8.0 kilometres (5.0 mi) to the line including a stop at Hongqiao Airport Terminal 2.^[9] On April 8, an eastward extension added 8 stations to the line, totaling 26.6 kilometres (16.5 mi) and taking line 2 to Pudong International Airport.^[10][11] On July 1, Hongqiao Railway Station opens to the public with the opening of the railway station of the same name.

In October 2006, it was decided to rename three stations on line 2 by the end of the year,^[12][13] adopting a new naming scheme: metro stations, unlike bus stops, are no longer supposed to be named after neighbouring vertical streets, but famous streets and sights in the vicinity, making it easier for visitors to find these places. The renamed stations are Century Avenue (formerly Dongfang Road), East Nanjing Road (formerly Middle Henan Road) and West Nanjing Road (formerly Shimen No. 1 Road).

Up to April 19, 2019, when an eight-car train started serving the whole line 2 in a regular schedule,^[16] the east section of line 2 was served by a four-car fleet. Line 2 had a piecewise service pattern during morning peak hours whereby the suburban segment between Guanglan Road station and Pudong International Airport station (Now Pudong Airport Terminal 1&2 station) is partially served by a four-car fleet in addition to the regular eight-car fleet serving the whole line. Already since 28 December 2018, during off-peak times, an eight-car fleet from National Exhibition and Convention Center station or Songhong Road station may terminate at Pudong Airport Terminal 1&2 station, but most trains still terminate at Guanglan Road station or Tangzhen (only during peak hours).
