Some call them vanity URLs, other Facebook user names but you can grab your organization's moniker starting starting at 12:01 a.m. eastern on Saturday, June 13. At that point, you'll be able to choose a username on a first-come, first-serve basis for your personal profile (many folks have a personal profile that's work oriented or doubles as personal and professional) AND the Facebook Pages that you administer (only those established by May 31, 2009 and with 1,000 fans or more). Do it here.
If your organization's name or program names are trademarked, go here to prevent the registration of those as usernames by others. But most critically, think carefully about the username you choose. Once it's been selected, you won't be able to change or transfer it!
Here's more on usernames for Facebook pages.
This is a great branding opportunity, and one that's particularly important as more giving moves online. It'll allow your organization to feature a Facebook page URL that's easy to remember — something like www.Facebook.com/CommunityFoodBank — and should be incorporated in all marketing communications, including your email sig lines when appropriate.
If your page doesn't meet the mark at this point, keep checking back with Facebook. It's likely they'll relax the criteria for being able to designate a username after a month or so!
