Key facts

  • Send mail to Waiawa Correctional Facility, 94-560 Kamehameha Highway, Waipahu, HI 96797 — the institution's inmate-mail address, not its street address.
  • Hawaii sends mail to each facility directly. Address it to the incarcerated person’s full name and SID (State Identification) number, then the facility’s own address.
  • Include your full name and return address. Mail without the SID number can be delayed — call the facility if you don’t have it.
  • Incoming mail is screened for drugs (the DCR uses scanners that detect contraband without opening the envelope) and inspected before delivery.
  • Confirm the person’s current facility before mailing — Hawaii also houses some people at the Saguaro Correctional Center in Arizona, which has a separate address.
  • PostPal prints and mails your letter for you the next business day for $5 — with your return address printed so the inmate can write back, and no printer, envelope, or stamp needed.

How to send your letter

  1. 1

    Confirm the person is still at Waiawa Correctional Facility

    Inmates are transferred between facilities without notice. Confirm they are still at Waiawa Correctional Facility — and double-check the SID number — before you mail anything, using the Hawaii Department of Corrections and Rehabilitation (DCR)'s official inmate locator.

  2. 2

    Address it exactly

    First line: the inmate's full committed name and SID number. Then Waiawa Correctional Facility, 94-560 Kamehameha Highway, Waipahu, HI 96797. Add your full return address.

  3. 3

    Keep the contents allowed

    Plain letter-size paper is safest. Do not enclose cash, stamps, gift cards, or any object other than paper — prohibited items get the whole letter rejected. Check the mail rules above before adding photos.

  4. 4

    Send it without a printer

    Write or upload your letter to PostPal with this address prefilled, and we print, envelope, and mail it via USPS the next business day for $5 — your return address printed so they can reply.
