The service operates 24 hours per day, 7 days per week, 365 days per year.
Calls to 111 will be assessed, advice given and, if needed, patients will be directed to the most appropriate local health services. This could be Accident and Emergency (A&E), an urgent care centre, an out of hours GP, a community nurse, a walk-in centre, an emergency dentist or a pharmacy.
There are now only three numbers to know: 999 for life-threatening emergencies, your GP surgery telephone number and 111.
Calls to 111 are free, including from mobiles. For more information, including leaflets about NHS 111 in different languages, please visit the NHS Choices website. NHS Choices also has lots of health information including symptom checkers.
