Surrey Police appealed for help to find 14-year-old Emma and 15-year-old Matthew from Farnham last week after they were reported missing from their homes last Thursday (October 28) morning.
But on Friday, the force issued an updated statement confirming they had been found.
A police spokesman said: "We are pleased to report that missing teenagers Emma and Matthew have been found safe and well.
"Emma and Matthew were reported missing yesterday (October 28).
"Thank you to everyone who provided information and shared our appeal."
