If you try to register multiple Gmail accounts from the same location (such as a public library), at some point Gmail will start to ask you for a phone number verification. This is something I saw a few years ago in France (before GDPR), there is no reason it has changed. I suspect it is to avoid fraudulent accounts while still letting a few mails being registered without verification for first time users in a location.
