Hi, could someone explain how U.S. athletes (and other types of celebrities) are able to use pseudonyms when checking in at a hotel in the USA?

In Europe, where I live, checking in at a hotel usually needs a valid I.D. document (such as a passport or drivers licence) which always contains a persons real name.
