NHS COVID Pass
Digital versions can be accessed by downloading the NHS App (you must be registered with a GP surgery in England), or by using the online NHS COVID Pass service. Paper versions can be requested online or by calling 119 if you’re travelling in more than 4 weeks’ time. You also need to make sure your NHS COVID Pass and Passport are both in the same name.
