Phone numbers are bad, but of course it could be worse. Phone numbers have both escape hatches (VOIP, shared number burner services, or your own psuedonymous SIM + device ID), and friction (people are wary of businesses spamming them).
Pseudonyms don't work for the topic under discussion, issuing credit. And for the general case, since credit issuers would be able to require you to do a non-psuedonym identification, then any other entity can require this as well, unless there were a privacy law.
