What happens after I submit a listing?

This is what to expect after you send in your listing:

• You will receive a confirmation email. You will need to confirm your listing through this email.
• Our staff will review your submission and verify that it meets our listing policy.
  • If approved, you will receive an email notification. You will need this email later. Please keep it for your records.
  • If your listing does not meet our listing policy, you will receive an email explaining why and with recommendations on how to revise your submission.
• Approved listings usually appear on our website the following business day.

Listings on our website expire in 30, 60 or 90 day periods. You should receive an email three (3) days before your listing is set to expire asking if you would like to extend your listing for another 30, 60 or 90 days. If you do not respond to that email by the time your listing expires, your listing will be removed from the IMEX listings page.

How do I delete or change my listing?

• If you exchange your material and want to take down your listing, click the "exchanged" link in your approval email.
• If you exchange some of your material and want to list the remaining material, email us at imex@kingcounty.gov and we can help facilitate the re-submittal process.
