How to open an account on Craigslist
You don't need a Craigslist account to use the site's features. You can, for example, post an ad without an account and remove or edit it later by following the link in the email Craigslist sends. If you post rarely, setting up an account may be more trouble than it's worth. For the frequent poster, however, an account can be very helpful. It keeps track of all your posts in one place, making it easier to sort through, edit or remove them.
Direct your browser to Craigslist's "Account Signup" page.
Type your email address into the appropriate field on this page, then type the verification words into the field below where they appear. Click the "Create Account" button.
Go to the inbox of the email account you used to sign up for your Craigslist account. You should have an email from Craigslist with a link to your account. Click this link.
