Shipping cremated remains by mail in the United States
Shipping cremated remains is not the same as sending an ordinary parcel. The contents are deeply personal, irreplaceable and subject to specific USPS requirements. Whether ashes need to be sent to a family member, a funeral home, a cemetery, a memorial park, an artist or another destination, careful preparation helps prevent delays and gives everyone involved more peace of mind.
In the United States, human and animal cremated remains must be mailed through USPS using the required USPS cremated remains shipping process. This includes Priority Mail Express or Priority Mail Express International service and the USPS Priority Mail Express Cremated Remains Box. The same care applies when ashes are shipped inside keepsakes or cremation jewelry.
In short: cremated remains should be placed in a sealed, sift-proof inner container, protected inside the required USPS Priority Mail Express Cremated Remains Box and shipped with the correct USPS service. Before sending ashes, always check the latest USPS requirements, confirm the destination address and ask the receiving funeral home, cemetery, crematory, artist or family member whether they need specific documents.
Can you ship cremated remains in the United States?
Yes, cremated remains can be mailed within the United States, but they must be sent according to USPS rules. Human and animal cremated remains are treated as restricted matter. This means they are mailable only when the correct USPS service, box and preparation requirements are followed.
This applies not only to ashes in a temporary cremation container or urn, but also to keepsakes and jewelry that contain cremated remains. Because the contents cannot be replaced, the most important goals are secure packaging, clear identification and reliable tracking.
Which USPS service and box should you use?
For domestic mailing in the United States, cremated remains must be sent through USPS using Priority Mail Express service and the USPS Priority Mail Express Cremated Remains Box. This special box is designed to make cremated remains shipments clearly visible during postal handling.
For international mailing, USPS allows cremated remains only through Priority Mail Express International, and only if the destination country accepts cremated remains. International rules can differ by country, so always check USPS country restrictions and the requirements of the destination country before mailing ashes abroad.
Do not treat cremated remains as an ordinary parcel. Do not rely on older instructions about using your own box with a separate cremated remains label. Current USPS guidance requires the USPS Priority Mail Express Cremated Remains Box for these shipments.
How should cremated remains be packaged?
The most important rule is that the ashes must be secure. Cremated remains should be placed in a sealed and sift-proof inner container. This can be a temporary cremation container, a funeral urn, a keepsake, a jewelry item or another suitable container, as long as it is properly closed and ashes cannot escape.
For detailed packing, addressing and mailing instructions, read the official USPS packaging guidance in Publication 139.
The inner container should then be protected inside the required USPS cremated remains box. Use enough cushioning material so the container cannot move during transit. This is especially important if the urn or keepsake is fragile, heavy, handmade or made from ceramic, glass, stone or metal.
A careful shipment usually includes:
- A sealed and sift-proof inner container for the cremated remains
- The required USPS Priority Mail Express Cremated Remains Box
- Cushioning material to prevent movement inside the box
- Clear return and delivery addresses
- Tracking information and postal receipt
- Any documents requested by the recipient
- Customs documentation for international shipments
The package should be sift-proof. This means powders should not be able to escape from the inner container or outer package. This protects the contents, other mailpieces and postal equipment.
Should you use the USPS Cremated Remains Box?
Yes. For mailing cremated remains through USPS, use the USPS Priority Mail Express Cremated Remains Box. USPS offers cremated remains kits through the USPS Postal Store. These kits are made for cremated remains shipments and help make the package clearly identifiable during handling.
The box does not replace careful packaging. The urn, keepsake, jewelry item or temporary container still needs to be sealed and protected inside the package. If the urn is fragile, heavy, ceramic, glass, stone or metal, add extra cushioning and avoid letting the object press directly against the outer box.
What documents should you include?
USPS rules focus mainly on shipping service, packaging, markings and customs information for international shipments. In practice, it is wise to keep documents with the sender and, where appropriate, include copies for the recipient. This is especially useful when cremated remains are being sent to a funeral home, cemetery, crematory, memorial park, columbarium provider or artist.
Useful documents may include:
- A copy of the cremation certificate
- A death certificate, if requested by the receiving party
- Contact details for the sender and recipient
- Instructions from the funeral home, crematory, cemetery, memorial park or artist
- Customs documentation for international shipping
