How to Address Mail to Someone at IMCC Using Iowa DOC’s Pigeonly System

Sending non-legal mail to someone at Iowa Medical and Classification Center (IMCC)? You'll need to address it to Iowa DOC's central mail processor, not to the prison itself. Here's the exact format to use so your letter gets processed and reaches the right facility.

Iowa DOC routes all incoming non-legal mail through a central processing location to help prevent mail contraband. That's why envelopes for IMCC go to Pigeonly's processing P.O. box in Las Vegas: PO Box 96777, Las Vegas, NV 89193. Pigeonly Corrections runs this offsite processing facility, and Iowa DOC says there's no additional cost to you as the sender.

Reminder: If you send non-legal mail directly to an Iowa DOC facility, it will be returned to the sender.

Your envelope needs four pieces of information: the incarcerated person's full name, their offender ID number, the facility name with the correct facility code, and the Pigeonly Las Vegas P.O. box address. For IMCC, the facility code is 1108. Write it as "Iowa Medical and Classification Center (IMCC) - 1108." Getting this code right is what ensures your processed mail gets routed to IMCC after it arrives at PO Box 96777 in Las Vegas.

  • Incarcerated Person’s Full Name
  • Offender ID Number
  • Iowa Medical and Classification Center (IMCC) - 1108
  • PO Box 96777
  • Las Vegas, NV 89193

Once your non-legal mail arrives at the offsite processing location, Pigeonly opens it and scans it into a digital color copy. That copy is then printed and delivered to the appropriate Iowa DOC facility.

Do not send irreplaceable originals. Original non-legal mail is temporarily stored and then securely destroyed under Iowa DOC policy. Originals are not returned to the sender.

  • Letters (including children’s drawings)
  • Greeting cards
  • Postcards
  • 4x6 photos (limit 10)
  • Unbound newsletters

You can include photos in your U.S. Mail using the Pigeonly address format for IMCC, as long as you stay within the photo limit. Iowa DOC also notes that Pigeonly offers additional paid services, which may include cards, photos, and messaging.

Photo rule: Stick to 4x6 prints and keep it to 10 photos per mailing.

  1. Confirm the person’s full name and offender ID. That offender ID number needs to be on the address.
  2. Use IMCC’s facility code and the Las Vegas P.O. box. For IMCC, write “Iowa Medical and Classification Center (IMCC) - 1108,” then address it to PO Box 96777, Las Vegas, NV 89193.
  3. Write the address clearly. Clean, legible addressing helps avoid routing delays.
  4. Only mail what you can replace. Originals are not returned, they are temporarily stored and then securely destroyed.

The fastest way to get mail sent back to you? Sending it straight to IMCC. Non-legal mail sent directly to the facility will be returned, so always use the Pigeonly Las Vegas address instead.
