Everything you need to write with confidence
How to find someone, what you can send, and the mail rules that keep your letter from being turned away.
How do I find or look up an inmate?
You can start right here on our Write to Prisoners page. To search more broadly, use the free Federal Bureau of Prisons Inmate Locator for federal inmates, or your state's Department of Corrections (DOC) “offender search” for state facilities. You'll need the person's full name or ID number, and the tool will show their current facility and mailing address.
What exactly do I write in a first letter?
Keep it short, warm, and honest. Introduce yourself by first name, mention that you wanted to reach out, and share something ordinary — a book you're reading, the weather, a bit of encouragement or prayer. You don't need to discuss their charges or sentence; let them lead if they want to. Sincerity matters far more than length.
What information goes on the envelope?
You must include the person's full committed name and their ID/inmate number, followed by the exact facility address. Without the ID number, mail is often returned. Always add your own return address — a P.O. box is perfectly fine if you'd rather not share your home address.
What am I allowed to send?
Rules vary by facility, but generally you can send plain handwritten or typed letters and a few standard photos. Commonly banned items include: cash, stamps, stickers, glitter, crayon or marker, laminated items, Polaroids, anything with a strong scent, and inappropriate images. When in doubt, stick to paper and blue or black ink. Check the specific facility's website before sending anything unusual.
Is it safe? Do I have to share personal details?
Yes, letter-writing is a well-established ministry. Protect your privacy by using a P.O. box for your return address and sharing only what you're comfortable with. Never send money, gift cards, or account information, and be cautious of any request for financial help. Trust builds slowly — there's no need to rush.
How long until I get a reply?
Expect anywhere from a few days to several weeks. All incoming and outgoing mail is screened by the facility, which adds time, and postage or paper isn't always easy for someone inside to come by. Patience and consistency are the real gift — keep writing even before you hear back.
Do I have to be Catholic — or religious at all — to write?
Not at all. Our ministry is Catholic-rooted and many of the people we serve are Catholic, but anyone with a kind heart is welcome to write, and the people you write to come from every background. Share your faith if it's natural to you; more than anything, just be a caring, steady presence.
Can I write anonymously or through the ministry?
You should always use a real return address so replies can reach you, but that can be a P.O. box rather than your home. If you'd like guidance or prefer extra privacy, reach out through our Contact page and we'll help you get started safely.
