How do you find out who posted on Craigslist?

Theres a chance that you can uncover who posted the ad by entering that phone number in an online reverse directory, such as White Pages, AnyWho or Intelius. Look for the Reverse Phone Lookup on those sites.

How long does it take for my ad to appear on Craigslist?

You can expect your paid posting to appear within 10 to 20 minutes after you complete it, or 15 minutes after you confirm your email address on a free ad.
