If your first letter gets through, odds are you’ll write again—and that's the goal. Sending a letter is one of the simplest, most impactful forms of support. This guide walks you through the rules and logistics so your mail makes it to its destination.

1. Pick Someone to Write
Start with our Prisoner Registry. We include current mailing addresses and any facility-specific notes when available.
2. Confirm Their Location
People get moved. Before mailing anything, double-check the person’s location using VINELink, the federal inmate locator, or a state corrections lookup. Many such links are available on our Tools Page.
3. Follow the Rules
Most facilities require:
- White paper only, single-sided
- Plain envelopes—no security patterns or designs
- Typed or handwritten is fine, but use black or blue ink only
- No glitter, glue, stickers, or decorative items
- No cards, Polaroids, or printed photos unless explicitly allowed
- No perfume, stains, or smudges
Stay plain and simple—mailrooms reject anything even slightly questionable.
4. Include Your Return Address
Your return address must appear on both the envelope and the letter itself. If you prefer not to use your home address, consider a PO box or our Email Proxy.
5. Send It
Use standard postage. Assume staff may read it—so keep things respectful and clear. That said, it doesn’t need to be formal. Simple support matters.
