My name is Alice, and I'm one of the Guru Team here at Shopify, thanks for reaching out to us on the forums!
At this time, we have the option for a customer to checkout using a phone number, and if a customer chooses this option, then they can receive their updates on their order via SMS. If a customer opts for this option at the checkout, they cannot create an account unless they add their email address too. At this time, customers need to enter an email address to create an account and not just their phone number. You can see more on this here, and for sure it's something we can look to adding in the future as the platform expands! ?
I hope that helps and if you have any other questions or need anything at all, please let me know and I’ll do all I can to help!
