If your iPhone, iPad, or iPod touch is lost or stolen - Apple Support

razmee209 has already provided you with a support link on what to do if your iPhone is stolen.

In addition, you should do the following as soon as possible:

1. Change your Apple ID.
2. Contact your local law enforcement agency and report it stolen.
3. Contact your cellular provider so they can "blacklist" the phone. This will prevent it from being used on any cellular network.

Please read the advice in the link posted by razmee209 above.
