How Long Does Mail Take and How Do I Know It Arrived?

I sent an inmate a letter with pictures through this website last Tuesday. He says he hasn't yet received it. How long until he receives the letter and how do I know he received it? Is there something that lets us know he has officially received it ?

Once a letter is sent through InmateAid, delivery typically takes the same amount of time as standard US mail to that facility, usually a few business days

Once a letter is sent through InmateAid, delivery typically takes the same amount of time as standard US mail to that facility, usually a few business days depending on the location. There is no tracking confirmation sent to you when your inmate receives it. Mail delivered through the prison system works the same way a regular letter does once it leaves our hands, and facilities do not notify senders when mail is received.

If your inmate says they have not received something after a reasonable amount of time has passed, there are a few things worth checking. The most common reason mail does not arrive is an error in the inmate ID number or facility address on the profile. Even a single digit off on an inmate number can cause mail to be rejected or returned by the mail room.

When a letter comes back to us undeliverable, we research the issue and contact you with what we find. In some cases we discover that an inmate has been transferred to a different facility, or that the ID number on file does not match the facility's records. If we can identify the correct information, we will resend the letter at no charge.

If you have any concern about a letter that seems to be taking longer than expected, reach out to InmateAid directly at aid@inmateaid.com. We will follow up with the facility's mail room on your behalf and let you know what we find.
