Craigslist allows you to set a specific location for an item in the "Specific Location" box. Although Craigslist sites are broken down by city, the specific location box is helpful if your town does not have a Craigslist site and you are posting the item on the nearest metro area's site. It's also useful for specifying a neighborhood or community within a city. You can access the listing editor to change the specific location after creating your Craigslist ad.
Visit the Craiglist site for your city and click "My Account." Sign in to your account to bring up the listing editor.
Access the email address you used to create the listing, if you did not create a Craigslist account when you listed the item. Click on the email you received from Craigslist marked "POST/EDIT/Delete -[Item Name]."
Click on the "Edit Again" button at the bottom of the listing page.
Scroll to the "Specific Location" box. Delete the current specific location, and then type the new location.
Click on "Continue" to save the changes to your item's location.
