How do most people receive their C19 vaccine invite?

Phone call? Text, letter?
I imagine the invitation typically lists a variety of ways to book, most typically thru a website or app, but also thru 0845 type phone number - correct?

How many/What identity checks happen when booking?

Do people typically get a confirmation afterwards, such as a letter for those that don't have email/mobile?

My parents had a phone call from the GP. I am at a different GP and had a text to book. None of us were asked for ID when we went. Just asked for date of birth.
