How to Mail Cremated Remains: USPS Packaging and Shipping Guide

Mailing cremated remains can be a practical way to reunite family members, bring a loved one to a chosen resting place, or send a small memorial portion to someone who cannot travel. The process has specific USPS packaging and service requirements, and international shipments have an additional destination-country check. Taking time to confirm the recipient, current postal instructions, and delivery arrangements can make a difficult task more manageable.

This guide covers mailing human or animal cremated remains through USPS. It is general information, not legal advice. Postal rules and destination requirements can change, so verify the current instructions with USPS before preparing a shipment. If you are deciding whether or how remains may be divided or transferred, ask the crematory, funeral provider, or other qualified professional familiar with your circumstances.

Start with the recipient and the reason for mailing

Before ordering a box or creating a label, confirm where the remains are going and who can receive them. Ask the recipient to confirm the exact name and address, the best delivery location, and whether someone will be available to accept the parcel. If the destination is a funeral home, cemetery, columbarium, or crematory, contact the organization first. Ask whether it can receive the shipment, which name should appear on the address, and whether it has specific receiving hours or instructions.

Clarify what is being mailed. It may be a full container, a smaller portion shared with a relative, or an object that incorporates cremated remains. USPS states that its cremated-remains packaging requirement applies to human and animal remains, including remains incorporated into jewelry, blown glass, or other artisan works. The permitted USPS services and packaging rules therefore matter even when the shipment is a small memorial item rather than a full urn.[1]

If you are arranging a family distribution, first make sure the recipient understands what is being sent and agrees to receive it. The article on sharing cremated remains among family may help you think through the family conversation. For decisions about an urn or container, see how to choose a cremation urn. These are separate questions from the USPS shipping rules: a suitable keepsake choice does not automatically make an ordinary shipping box acceptable.

Know which USPS service is permitted

USPS requires cremated remains to be mailed using Priority Mail Express. For international destinations where the service and shipment are permitted, USPS specifies Priority Mail Express International. The USPS guidance says no other service is allowed for these shipments. Priority Mail Express includes USPS Tracking, and USPS lists certain additional services that may be added, including Return Receipt, Insurance, Signature Required, and Signature Waived.[1]

Do not treat the service name as a suggestion or substitute another class because it appears cheaper, more convenient, or familiar. For example, a package containing cremated remains should not be sent using ordinary Priority Mail or another service that is not approved for this purpose. USPS also says stamps cannot be used for these packages. Postage can be purchased at a Post Office retail counter or created through Click-N-Ship or approved USPS PC Postage software.[1]

When using Click-N-Ship, USPS instructs customers to select “use your own package,” choose Priority Mail Express, and select “Cremated Remains Shipping” as the extra service. Follow the current on-screen process and the packaging instructions rather than relying on an old saved label or a previous shipment’s settings.[1]

Service availability and postage costs can depend on the shipment details. This guide does not estimate a price or promise a delivery date. Before finalizing plans for a ceremony, visit, or interment, check the service options and expected delivery information directly with USPS. Build in time to obtain the correct kit and address any questions, but do not assume a particular arrival date based on a general estimate.

Use the required USPS cremated-remains packaging

Since March 1, 2025, USPS requires postal-branded Priority Mail Express Cremated Remains packaging for all shipments of cremated remains, whether human or animal. USPS’s requirement also covers cremated remains incorporated into jewelry, blown glass, and other artisan works. An ordinary box, even a strong one, does not replace the required branded packaging.[1]

USPS lists four kit options: large and small kits, each available in a basic version or a version that includes additional packing materials and a copy of Publication 139. The listed large kit box measures 14¾ by 10¼ by 10 inches; the small kit measures 9 by 7¼ by 5 inches. The basic kits include a sturdy box and a roll of Priority Mail Express packing tape. The other versions also list bubble cushioning, a self-sealing plastic bag, and a copy of Publication 139.[1]

Those dimensions describe the outer kits, not a guarantee that a particular urn or memorial object will fit. Before ordering, compare the dimensions of the item and its existing container with the kit options. If you are unsure which kit is appropriate, ask USPS or the crematory for help rather than modifying a box or improvising a package. USPS directs customers to Publication 139, How to Package and Ship Cremated Remains, for the current packaging, labeling, and addressing instructions.[1]

Kits can be ordered through the USPS Postal Store, with orders limited to five kits at a time. Packaging may also be added through Click-N-Ship after a label has been created and placed in the cart. Some Post Office retail locations may have kits behind the counter, but not all locations stock them, and USPS says they are not displayed in retail lobbies. If you plan to obtain one at a local office, call or otherwise confirm availability before making the trip.[1]

Do not rely on an older instruction sheet that refers to Label 139. USPS says Label 139 has been discontinued and Post Offices no longer supply the orange label. The current postal-branded Priority Mail Express Cremated Remains packaging guidelines replace that older label approach.[1]

Prepare the shipment by following Publication 139

Once you have the correct kit, use the current version of Publication 139 for the exact packing sequence, labeling, and addressing. The USPS overview identifies that publication as the controlling guide for these steps, but the details may be revised. Read it before placing anything in the box, and keep it nearby while preparing the parcel. Do not substitute assumptions based on how ordinary packages are packed.[1]

Set aside enough time to work carefully. Choose a clean, stable surface and gather the required kit and the information you need for the address and postage. If another family member is helping, agree on who will check the instructions and who will verify the label. A second review can help catch a transposed digit or a name that does not match the recipient’s delivery arrangements.

Follow the specific directions for the inner container, any materials supplied with the kit, closure, and placement of the shipping label. Do not add materials or alter the packaging in ways that conflict with Publication 139. If the container is unusually shaped, fragile, too large for the available kit, or does not seem to fit the instructions, pause and ask USPS or the crematory what to do. Avoid forcing an item into a kit that does not appear suitable.

The purpose of this check is not to make the process feel clinical. It is to give the parcel the best chance of meeting the postal requirements and to reduce last-minute uncertainty. If handling the remains feels difficult, a trusted person may be able to assist with practical tasks. You can decide how involved you want to be; there is no single right way to approach the preparation.

Complete the label and keep a clear record

Address the parcel exactly as the recipient has confirmed, and follow Publication 139 for how the address and required markings are to appear. Use the required Priority Mail Express service and select the cremated-remains option when creating postage through Click-N-Ship. At a retail counter, tell the postal employee that the parcel contains cremated remains so the shipment can be handled under the correct service. USPS says postage may be bought at a retail counter or created using Click-N-Ship or approved PC Postage software.[1]

Before the parcel is handed over, compare the printed label with the recipient’s confirmed address. Check the recipient’s full name, organization if applicable, street or delivery details, city, state or region, postal code, and return address. If a funeral home or other institution will receive it, make sure the contact person knows the parcel is coming and can connect it with the right family or arrangement.

Keep a record of the tracking number and the date the package was accepted. Share the tracking information with the intended recipient if appropriate, and retain any receipt or postage confirmation. Tracking is included with Priority Mail Express, according to USPS.[1] A record can help the sender and recipient follow the shipment without relying on memory during an emotionally demanding time.

Choose optional services only after considering the recipient’s circumstances and the current USPS terms. USPS lists Return Receipt, Insurance, Signature Required, and Signature Waived as available additional services. Their conditions and suitability can vary, so ask USPS what each option means for this shipment rather than assuming that one is necessary or that it guarantees a particular outcome.[1]

Check international eligibility before preparing a parcel

An international shipment needs two checks: whether Priority Mail Express International is available to the destination, and whether the destination country permits cremated remains to enter. USPS says international mailing is allowed only when the destination country does not prohibit the contents and the service is available to that country. USPS directs customers to the destination’s Individual Country Listing in the International Mail Manual.[1]

Do not assume that a country’s acceptance of ordinary mail means it accepts cremated remains. Likewise, do not assume that a family member’s prior experience with another destination applies here. Rules can differ by destination, and the USPS country information may not answer every question about documentation or local receiving procedures. Check the current country listing and contact the relevant destination authority, funeral provider, or receiving organization if any requirement is unclear.

Confirm the recipient’s name and address in the format used at the destination, and ask the recipient to verify that they can receive the parcel. If a local funeral home or other professional is involved, ask whether it can advise on local receipt and any documents that must accompany the shipment. USPS’s general guidance does not establish every destination’s separate requirements; do not treat it as a guarantee of entry or delivery.

If the destination-country listing prohibits the contents, or if the required international service is unavailable, do not create a label and hope the parcel will be accepted. Pause and discuss another arrangement with the family and relevant professionals. A family may choose to carry remains in person, arrange a different transfer, or reconsider the timing or location of a gathering. Those alternatives have separate requirements; check them independently rather than assuming the mailing rules apply to travel.

Plan around the kind of remains being sent

A full urn or primary container

For a full container, check the dimensions and shape before choosing a kit. The small and large kit measurements can help you identify a possible fit, but the outer dimensions do not establish that every urn can be packed safely or according to USPS instructions. If a container appears close to the kit’s available space, do not compress, dismantle, or repack it without guidance. Ask the crematory or USPS how to proceed under Publication 139.

A smaller portion for a family member

A smaller portion may be part of a family’s remembrance plan, but it still falls under the USPS cremated-remains packaging and service requirements. Confirm that the intended recipient wants to receive it and that the container can be accommodated in the required packaging. If the choice to share remains has not yet been discussed, consider doing that before shipping. The practical steps for sharing and the postal steps are related, but they are not the same decision.

Jewelry, glass, or another memorial object

USPS expressly includes remains incorporated into jewelry, blown glass, and other artisan works in its packaging requirement. Do not assume that a small object can be mailed as an ordinary gift simply because the remains are enclosed in a finished keepsake. Use the required USPS packaging and service, and follow the current instructions for the object’s shape and protection.[1] If you are choosing a keepsake before mailing, the guide to cremation keepsake jewelry discusses the memorial-item decision separately from the postal workflow.

For any type of shipment, the person who accepts the package should know what is coming and how it will be delivered. If the recipient is away, has limited access to the address, or is coordinating a service, agree on a practical receiving plan before mailing. Mailing should not be treated as a substitute for confirming that the destination is ready to receive the remains.

Common mistakes to avoid

• Using a regular box. USPS requires its postal-branded Priority Mail Express Cremated Remains packaging for human and animal remains. Do not treat a sturdy household box as equivalent.[1]
• Choosing a different mail class. USPS specifies Priority Mail Express domestically and Priority Mail Express International for eligible international destinations. Do not substitute another service.[1]
• Using old Label 139 advice. USPS says the orange Label 139 is discontinued. Follow the current packaging guidelines and Publication 139 instead.[1]
• Assuming a local Post Office has a kit. Some locations may stock kits behind the counter, but not all do. Confirm availability or order through USPS before relying on an in-person pickup.[1]
• Skipping the international check. The destination must allow the contents, and Priority Mail Express International must be available. Check the country listing before preparing the parcel.[1]
• Creating postage without the required option. When using Click-N-Ship, follow USPS’s instructions to select the cremated-remains shipping extra service. Stamps cannot be used.[1]
• Sending before confirming receipt. A correct label cannot ensure that the intended person or institution is ready to receive the package. Confirm the destination and a receiving plan first.
• Relying on an old timeline. Do not promise a family that the parcel will arrive by a specific date based on a past shipment or a general estimate. Check current USPS information and plan with flexibility.

A practical pre-mailing checklist

Use this list as a final review, alongside the current USPS instructions. It does not replace Publication 139.

1. Recipient confirmed: The recipient or receiving organization has agreed to receive the remains and confirmed the address.
2. Shipment identified: You know whether the parcel contains a full container, a smaller portion, or an object incorporating remains.
3. Service checked: You are using Priority Mail Express domestically, or Priority Mail Express International only when it is available and the destination permits the contents.
4. Correct kit obtained: The parcel will use the required postal-branded Priority Mail Express Cremated Remains packaging, not an ordinary box.
5. Instructions reviewed: You have read the current Publication 139 directions for packaging, addressing, and labeling.
6. Address verified: The recipient’s name and address are checked against the information they supplied, and a return address is included as directed.
7. Postage completed correctly: The required cremated-remains shipping option is selected when creating postage, or the shipment is processed at a retail counter.
8. Tracking recorded: You have saved the tracking number and acceptance receipt, and the recipient knows what to expect.
9. International requirements checked, if applicable: The current country listing confirms that the contents are not prohibited and the required service is available.

If any item is uncertain, pause and ask USPS or the relevant professional before sending. A short delay to clarify an instruction is preferable to relying on an assumption about a regulated shipment.

When another arrangement may be more appropriate

Mailing is one option, not an obligation. A family may find that an in-person handoff, a later gathering, or a different destination works better. If you are considering a service at the place where the remains will ultimately be kept, planning a memorial service can help with the gathering itself. For the disposition or use of ashes, the separate guide to meaningful options for cremation ashes may help you consider choices without assuming that any one is right for every family.

If mailing is not possible or does not feel suitable, ask the crematory or funeral provider what transfer options are available. For a journey involving a body rather than cremated remains, the requirements are different; see guidance on transporting a body to another state. Do not use that process as a substitute for checking airline rules or other requirements for carrying cremated remains.

Families may also have different preferences about who handles the container, whether a memorial portion is shared, or when a gathering takes place. It is reasonable to make a plan that is practical and respectful for the people involved. No additional ceremony or keepsake is required in order to honor someone.

Sending remains with care

The essential sequence is straightforward: confirm who will receive the remains, choose the permitted USPS service, obtain the required postal-branded packaging, follow Publication 139, complete postage correctly, and check any international destination restrictions. USPS’s current overview is the key reference for its packaging and mailing requirements, including the discontinuation of Label 139.[1]

Take the process one step at a time. Ask questions when a container does not fit, the destination is unclear, or the instructions seem inconsistent. Keep the recipient informed and retain the tracking information. The care involved in planning the shipment can be part of a family’s practical support for one another, whether or not the mailing is connected to a larger memorial or ceremony.
