Can you forward mail from a P.O. Box? How USPS forwarding works
Yes, you can forward mail from a PO Box using USPS Change of Address. But Marketing Mail won't follow, private carriers never deliver to PO Boxes, and forwarding doesn't fix the bigger problem: banks and DMVs reject PO Box numbers as a primary address.
Yes, you can forward mail from a PO Box to another address using USPS's standard Change of Address process. You can also forward mail to a PO Box from a street address using the same process, as long as the box is active and registered in your name.
The catch: forwarding solves the mail receipt problem. It does not solve the address legitimacy problem, and for expats and nomads, the second problem is almost always the bigger one.
Yes, you can forward mail from a PO Box to another address using USPS's Change of Address process. You can also forward mail in the opposite direction, from a street address to a PO Box. Standard forwarding lasts 12 months and can be extended for up to 18 additional months for a fee. USPS forwards First-Class Mail, Priority Mail, and most USPS packages. It does not forward Marketing Mail. Private carriers (FedEx, UPS, DHL) do not deliver to PO Boxes, so there is nothing to forward for shipments sent through those carriers. The bigger limitation for expats and nomads: forwarding mail from a PO Box doesn't change the PO Box address. Banks, DMVs, and government agencies reject PO box numbers as primary addresses regardless of any forwarding arrangement. If you need a US address that works for banking, driver's license applications, and domicile documentation, a virtual mailbox with a real, non-CMRA street address is the right solution, not a PO box.
Can you forward mail from a PO Box?
Yes. USPS lets you submit a Change of Address request to forward mail from a PO Box to any other delivery address, including a street address, another PO Box, or an international address where USPS delivers. The process works in both directions: from a PO Box to a street address, or from a street address to a PO Box.
How to set it up
Two ways to submit a Change of Address:
- Online at usps.com: $1.10 identity verification fee; takes effect in 7 to 10 business days.
- In person at a post office: free; same processing time.
When you submit the request, choose between two types of forwarding:
- Temporary: runs for 15 days to 12 months. Use this if you expect to return to the PO box address at some point.
- Permanent: indefinite forwarding. USPS forwards your mail and notifies senders of the new address so they can update their records directly.
How long forwarding lasts
Standard forwarding runs for 12 months. Extended Mail Forwarding is available for an additional 6, 12, or 18 months for a fee, 18 months is the maximum extension. You can purchase the extension when you first submit the COA or while forwarding is already active.
One practical note: USPS sends a reminder about one month before your forwarding period expires. When forwarding ends, USPS returns mail to senders for 6 months with your new address printed on the label, giving senders the chance to update their records before the forwarding window closes entirely.
What USPS forwards and what it doesn't
Not all mail is treated equally in the forwarding system. Knowing what USPS will and won't forward prevents surprises.
USPS does forward:
- First-Class Mail: letters, bills, statements, cards
- Priority Mail and Priority Mail Express
- Most packages sent via USPS services
USPS does not forward:
- USPS Marketing Mail: standard bulk mail, catalogs, and most advertising flyers are not forwarded regardless of your forwarding setup. If you receive a high volume of Marketing Mail, it will not follow you to the new address.
- Some Media Mail items are forwarded only if the sender has specifically marked the item for forwarding, and you pay any additional postage difference at pickup.

The private carrier limitation
FedEx, UPS, and DHL do not deliver to PO boxes. They require a physical street address for delivery. This means anything shipped by a private carrier was never delivered to your PO box in the first place, there is nothing to forward.
If you receive packages from Amazon, online retailers, or any business that uses a private carrier, a PO box cannot receive those items regardless of any forwarding arrangement you set up. This is one of the most commonly misunderstood limitations of PO box use.
What PO box forwarding doesn't solve
This section matters most for expats and nomads.
Forwarding your mail from a PO box to a new address redirects the mail. It does not change what the PO box address is, a numbered box at a post office. And a PO box number is universally rejected as a primary address for:
- Bank account CIP verification: US banks require a physical residential address under the PATRIOT Act. A PO box number does not satisfy this requirement regardless of any forwarding arrangement.
- Driver's license applications: every US state requires a physical residential address. A PO box is not accepted.
- Government agencies: IRS, Social Security Administration, voter registration, and most state agencies require a physical address on file.
- Financial institutions and insurance providers: most require a residential street address, not a box number.
The forwarding arrangement is invisible to institutions. They see the address on your account, the PO box number - not the address USPS is forwarding your mail to. Changing the forwarding destination does not update your address with any institution. You must update those separately, directly.
For expats and nomads, this practical distinction matters: a PO box can receive USPS mail and redirect it elsewhere. It cannot serve as a legitimate primary address for banking, the DMV, or domicile documentation. Forwarding solves the logistics problem. It does not solve the address legitimacy problem.
Physical address verification for US banks: a guide for expats and nomads article explains what banks are actually checking for and which address types pass the CIP verification. What is a CMRA address guide covers why even some real street addresses fail that check.
What expats and nomads need instead
For expats and nomads who need a US address that works for both mail receipt and address legitimacy, the right solution is a virtual mailbox with a real street address from a registered provider, not a PO box.
A real street address from a virtual mailbox provider accepts all carriers including FedEx, UPS, and DHL. It provides an address that banks and government agencies can verify against public records. Depending on the provider and the state, it can also serve as the address on a driver's licence application.
The CMRA caveat matters here: not all real street addresses are equal. Addresses provided by CMRA-registered commercial mail services, like UPS Store locations, are flagged in the USPS database and may be rejected by bank compliance systems even though they are technically real street addresses. The CMRA designation is what separates a forwarding address that passes banking checks from one that gets flagged and rejected. Choosing a provider whose address is not CMRA-flagged is the key decision.

Frequently asked questions
Can I forward mail from a PO box to an international address?
Yes, USPS can forward First-Class Mail and some packages internationally where USPS international delivery applies. International forwarding takes longer than domestic and some mail classes may not be eligible. Check usps.com for current international forwarding eligibility before relying on this for time-sensitive documents.
How long does PO box mail forwarding last?
Standard forwarding lasts 12 months. Extended Mail Forwarding is available for an additional 6, 12, or 18 months for a fee. The maximum total extension under the Extended Mail Forwarding programme is 18 months beyond the initial 12-month period.
Does USPS forward packages sent to a PO Box?
USPS forwards most packages sent through USPS. Packages sent via FedEx, UPS, or DHL are never delivered to a PO box in the first place; those carriers require a physical street address and cannot deliver to a numbered box.
Can I use a PO box as my address for banking?
No. US banks require a physical street address for Customer Identification Program verification under the PATRIOT Act. A PO box number is universally rejected as a primary address. Physical address verification for US banks article covers what banks actually accept and how to document a qualifying address.
What happens to my mail when the forwarding period ends?
USPS returns mail to senders for 6 months after forwarding ends, with your forwarding address printed on the label. This gives senders the opportunity to update their records before mail stops being rerouted entirely.
Is forwarding mail to a PO box the same as having a PO box as my permanent address?No. Forwarding to a PO Box temporarily redirects your mail there, but the address on your accounts and records remains your street address until you update each institution directly. To use a PO Box as your permanent mailing address, you must update your address with each institution individually. The forwarding arrangement only handles mail in transit; it does not update any records.
Conclusion
Yes, you can forward mail from a PO Box, the USPS Change of Address process handles it cleanly in both directions. Standard forwarding runs for 12 months and can be extended. Marketing Mail and private carrier packages are the main exceptions.
For expats and nomads, forwarding is the easy part. The harder part is that a PO Box number doesn't meet the physical address requirements for US banks, driver's licenses or domicile documentation, and no forwarding arrangement changes that. If you need a US address that works across all of those purposes, a real street address from a non-CMRA provider is the right starting point.
