You can send Sandboxx letters from anywhere in the world to anywhere in the US. You can send letters to civilian and business locations and even US prisons.
Sandboxx letters sent to the following Basic Training locations have additional features like address formatting, overnight shipping, and tracking:
- MCRD Parris Island
- MCRD San Diego
- Lackland Air Force Base
- Fort Benning
- Great Lakes Naval Base
We also support all FPO/AE/APO/PPO locations. Foreign non-military destinations are not currently supported. Letters sent to FPOs or Ships will be delivered along with other USPS letters sent to those addresses.
All Sandboxx letters, to any location, contain a pre-addressed reply envelope. Each reply envelop has a First Class US stamp printed on it. If you are sending from abroad, this postage might not be sufficient for the reply envelope to get back to you. Your recipient would just need to add the appropriate postage alongside the First Class stamp.
If your address does not appear in the list of suggested locations, just select “Enter Address Manually”. (Note, we cannot verify the accuracy of your address format if you chose this option.) If you are having difficulty entering an address, please don’t hesitate to reach out through the Sandboxx app. (Just tap Team Sandboxx on iOS or the white conversation icon in the top right of the home page for Android).
