It’s essential to ensure that your Facebook profile has a username set. However, we’ve encountered situations where Facebook prevents users from creating a username, particularly with brand-new accounts. Fortunately, we have a solution for this!
Facebook allows users to create up to four additional internal profiles within one account. You can find more details in this article: https://www.facebook.com/help/5637701596308695/?helpref=faq_content.
If you’re unable to create a username for your main profile, some users have successfully created an additional profile where Facebook permits adding a username, effectively bypassing the issue.
This approach also offers the advantage of starting fresh with a new profile, allowing you to build a targeted friends list from scratch.
