Because 12345 belongs to the public service hotline, it was set up by the Chengdu Municipal People's Government to facilitate the general public and improve the government's urban management and public service level. Through this hotline, many related policies can be consulted or problems can be reflected to relevant government departments for them to solve.
Therefore, if you need to consult the 12345 service hotline in Chengdu, just dial directly, without adding the area code.
