TL;DR: A domicile address is a physical, residential, or dedicated business street address where a trademark applicant lives or operates their primary business. The USPTO requires a domicile address for all trademark applications to crack down on fraudulent filings. P.O. boxes, virtual offices, and registered agent addresses will not satisfy this requirement.
If you are filing a trademark application, you might be surprised to find that the United States Patent and Trademark Office (USPTO) requires you to provide a “domicile address.”
For many business owners—especially those who work from home or use a P.O. Box for privacy—this raises a few immediate questions. Here is a breakdown of what a domicile address is, why the USPTO demands it, and how to protect your privacy when providing it.
Why Does the USPTO Require a Domicile Address?
A few years ago, the USPTO updated its rules and procedures to mandate a physical domicile address for every single trademark applicant.
The primary goal of this rule change was to crack down on scammers and fraudulent trademark filings, particularly from overseas bad actors who were hiding behind virtual addresses. By forcing applicants to provide a verifiable physical location tied to the owner, the USPTO aims to maintain the integrity of the trademark register.
Whether or not this policy has actually reduced scams is up for debate, but the reality is that the rule is here to stay. Every applicant must now have a physical address tied to their trademark file.
What Counts (and Doesn’t Count) as a Domicile Address?
The USPTO is incredibly strict about what qualifies as a domicile address. If your main business address falls into any of the “unacceptable” categories below, you will receive an Office Action from the USPTO requiring you to provide an actual domicile address before your application can proceed.
Here is a quick reference guide to what the USPTO will and will not accept:
| Unacceptable Addresses (Will Trigger a Refusal) | Acceptable Domicile Addresses (Can be hidden from public records) |
| P.O. Boxes | Your personal home address |
| Virtual office spaces | A home address of one of the business owners/officers |
| Shared office spaces (without a dedicated suite specific to your business) | A dedicated, physical commercial office or storefront |
| Mail drop locations (e.g., The UPS Store, Mailboxes Etc.) | |
| “Care of” addresses (e.g., law firm’s address) | |
| A registered agent’s address |
What About My Privacy?
If you run a home-based business or use a P.O. Box specifically to keep your home address off the internet, you might be hesitant to hand your residential address over to a federal database.
Fortunately, your domicile address can be hidden from the USPTO’s public records. If you use a P.O. Box or a virtual office as your public mailing address, you can list that as your primary correspondence address. You will still be required to provide your physical domicile address to the USPTO on the backend, but you can request that it be masked. This ensures your home address is not easily accessible to someone randomly searching public USPTO files.

Frequently Asked Questions (FAQs) About USPTO Domicile Addresses
Can I hide my home address from the public USPTO database? Yes. If you operate your business out of your home and want to protect your personal privacy, the USPTO forms allow you to provide two different addresses. You can list a P.O. Box or a virtual office as your public Mailing Address, and enter your actual home address exclusively in the hidden Domicile Address field. As long as you keep these fields separate, your home address will remain masked from the public-facing trademark database.
What if my domicile address is outside the United States? If your primary residence or principal place of business is located outside of the US, you must provide that foreign domicile address. However, providing a foreign address triggers a strict USPTO rule: all foreign-domiciled trademark applicants must be represented by a U.S.-licensed attorney. You cannot file or respond to USPTO actions on your own.
Does the USPTO actually verify the address I provide? Yes, they absolutely do. USPTO examining attorneys regularly check submitted addresses against USPS databases and commercial mail receiving agency (CMRA) lists. If the address you provide flags as a UPS Store, a virtual office building, or a mail-forwarding service, the examining attorney will issue an Office Action formally rejecting the address and pausing your application until a valid physical location is provided.
What if I travel full-time and genuinely do not have a fixed physical address? If you are a “digital nomad” or live full-time in an RV without a permanent physical residence, you cannot simply bypass the rule. Instead, you must file a formal “Petition to the Director” of the USPTO requesting a waiver of the domicile address requirement. In this petition, you must provide a verified statement of facts explaining your extraordinary living situation and why you cannot provide a standard fixed address.
