Clarinda's code is 1107, one digit from Anamosa's and one from the Medical and Classification Center's, so it is worth checking twice. Send letters and photos in minutes.

Iowa routes personal mail for every one of its prisons through a single PO Box in Nevada, and separates them by a four-digit code on the address block. Clarinda’s is 1107. Get the code and the box right and the letter goes through; get either wrong and it does not arrive late, it comes back, because Iowa states that non-legal mail sent directly to a prison is returned to sender. What arrives inside is a colour scan rather than the paper you posted.
[Full Legal Name, Offender ID Number]
Clarinda Correctional Facility - 1107
PO Box 96777
Las Vegas, NV 89193
1107 is Clarinda’s code. It is what tells the processing centre which of Iowa’s nine prisons a scanned letter belongs to.
The codes sit close together and a slip lands somewhere real rather than nowhere. Anamosa is 1106 and the Iowa Medical and Classification Center is 1108, one either side of Clarinda’s. Check the digit before you seal the envelope.
The name and offender ID number come from Iowa’s offender search.
The department’s wording admits no exception: any non-legal mail sent directly to an IDOC facility will be returned to sender.
So 2000 North 16th Street is where you go to visit and not where you post a letter. Because Clarinda is in the far southwest corner of Iowa, a letter that bounces has a long round trip before it comes back to you.
Iowa’s correspondence policy names the vendor in its own text rather than describing an anonymous processor: the department contracts with Pigeonly Corrections as its approved mail vendor.
The sequence: the letter arrives at the Nevada PO Box, Pigeonly Corrections opens all non-legal mail and scans it into a digital colour copy, and that copy is printed and delivered to the correct Iowa prison. The paper original is held for 45 days rather than destroyed right away, and the sender can request it back in that window.
It costs you nothing beyond the stamp.
The photo size and the ten-photo count are both firm.
Posted photos are scanned. 4x6, ten at a time, and what arrives is a colour copy rather than the print you put in the envelope.
Photos picked on your phone and sent through Pigeonly reach Clarinda as real colour photographs, printed as photos instead of copied from a scan.
From the far southwest corner of Iowa, where everything else takes longer, that difference is worth knowing.
The original is not destroyed right away. Pigeonly holds it for 45 days, and the sender can request it back for free any time before the last 7 days of that window, so the request needs to go in within the first 38 days.
The parcel goes back only to the address written on the envelope, and the request needs the recipient’s name, offender ID number and facility exactly as they appear on it. It is a one-time request, so a child’s drawing has to be requested on its own, and requested again for the next one.
If the 45 days pass without a request, the original is destroyed and what stays on file is the colour scan already delivered to the facility.
Iowa’s own policy names Pigeonly as the processor, which means a letter you post is travelling to us before it goes anywhere near Clarinda.
That transit is where the time goes. A posted letter spends 3 to 5 business days reaching a Nevada PO Box before any processing begins, and the scanning, screening, printing and shipping back to Iowa all follow after that.
With a free Pigeonly account, a letter for code 1107 never rides to Nevada in a mail sack. You write it on your phone, it is prepared where the processing happens, and the stamp that the posted route still costs you drops out along with the printer and envelope.
The PO Box above is still correct and still works. This is the same destination without the days spent reaching it.

Iowa’s family-facing page caps a message at 13,000 characters or 100 lines, about two pages. Two of the department’s own policies say 14,000 characters instead. That is Iowa’s contradiction rather than ours, and it stands.

To their full legal name and offender ID number, then the line Clarinda Correctional Facility - 1107, then PO Box 96777, Las Vegas, NV 89193. The 1107 is Clarinda's routing code and it tells the processing centre which of Iowa's nine prisons the letter is for.
MailEasier than it should be, because Iowa's codes run in sequence. Anamosa is 1106 and the Iowa Medical and Classification Center is 1108, so Clarinda's 1107 sits between two real codes and a single wrong digit routes your letter to a different prison rather than failing outright.
MailIt comes back. Iowa states that any non-legal mail sent directly to an IDOC facility will be returned to sender, so 2000 North 16th Street is the address for a visit and not for a letter. Given Clarinda's position in the far southwest of the state, that is a long round trip before you get it back.
MailThey get a colour scan of it. Pigeonly Corrections opens and scans non-legal mail, and the copy is printed and delivered to the prison. The paper original is held for 45 days rather than destroyed right away, and you can request it back for free at pigeonly.com/parcel-request within the first 38 days.
MailIowa's correspondence policy names Pigeonly Corrections as the processor, which means a posted letter travels to us before it reaches Clarinda, spending 3 to 5 business days in transit before any processing starts. A free Pigeonly account removes that leg: you upload from your phone and it is printed and prepared from the processing side instead.
MailTen, at 4x6. Iowa's accepted list is letters including children's drawings, greeting cards, postcards, 4x6 photos limited to ten, and unbound newsletters. Photos sent by post are scanned like everything else, so a printed copy arrives rather than the print you sent.
MailNot to Nevada, but Iowa publishes no facility-level legal mail address. The return-to-sender rule covers non-legal mail specifically, and legal correspondence is handled separately. Confirm the exact address with Clarinda on 712-695-7140 before an attorney sends anything.
MailYes, through Pigeonly. Photos uploaded from your phone are printed as real colour photographs and delivered as photographs, and they skip the postal leg entirely. A photo dropped in the post is scanned like every other enclosure, so a colour copy is what arrives.
MailThe offender ID number the envelope needs.
