Is it legal to use someone else's address for an LLC?

With their permission, you can often use another person's address as a mailing or principal address. It does not work as a registered agent unless they agree to act as the agent. Using an address without permission, or to conceal who runs the business, can be treated as a false filing, and the rules vary by state.

Can I use a family member's address for my LLC?

Yes, with their clear permission, a family member's address can serve as a mailing or principal address. Keep in mind that business mail, tax notices, and service of process for the LLC can arrive at their home, so make sure they understand and agree before you list it.

What happens if someone used my address for their LLC?

You can contact the business division of the state where the LLC was filed to report it and ask how to dispute the record. It is also worth watching for mail arriving in that business name at your address, since that mail is meant for an entity you do not control.

Can You Use Someone Else's Address for Your LLC?

Key takeaways

You can sometimes use another person's address for your LLC, but only with their clear permission and only for certain slots, such as a mailing or principal address.
It does not work as a registered agent unless that person agrees to act as the agent, because the registered agent must consent and be available to accept legal mail.
Using an address without permission, or to hide who is behind the business, can be treated as a false filing, and the rules vary by state.

Before you start

Get written permission from the person whose address you want to use, since their home will receive business and legal mail.
Separate the slots first: a mailing address, a principal address, and a registered agent address each follow different rules.

Who this is for

Founders thinking about using a friend's or family member's address for a new LLC.
Owners weighing a borrowed address against getting their own business address.
Anyone who discovered their address was used for a business they do not own.

You can sometimes use someone else's address for your LLC, but only with their permission and only for certain slots. Their address can work as a mailing or principal address, while using it as your registered agent, or without consent, creates legal and practical problems.

This guide covers where a borrowed address is allowed, what can go wrong, why permission matters so much, and why a business address of your own is usually the cleaner answer.

Yes, With Permission, and Only for Some Slots

Like most address questions, the answer depends on which slot you mean. A friend or relative's address behaves differently across the three places your LLC needs an address.

Slot	Someone else's address?	Condition
Mailing or principal address	Often workable	With their clear permission, since their home receives the business mail
Registered agent	Only if they agree to be the agent	The person must consent in writing and be reachable at that address often enough to accept service of process, with the exact standard set by state law
Bank account	Risky	Banks expect an address tied to the business and may question a mismatch

Permission is the thread running through all three. An address you have not been given the right to use is the core problem.

What Can Go Wrong

Even with permission, borrowing an address pushes real consequences onto someone else. It helps to know what you are asking them to take on.

Legal mail and service of process for the business can be delivered to their home, including documents tied to a lawsuit. Delaware, for one, requires an agent to be present often enough to accept service and forward it to the company.
Government and tax notices arrive at their address, so a missed letter becomes their problem to forward to you.
If they move or change their mind, you lose the address and have to update every filing that used it, including IRS Form 8822-B for the business mailing address or location.
Their privacy is affected, since the address becomes part of your public business record.

Permission is not a casual yes over text. The person is agreeing to receive your business and legal mail, and in some cases to be named on public filings, so it is worth treating like the commitment it is.

Put it in writing

Get clear, written permission, and make sure the person understands that service of process and tax notices for the business can arrive at their door. A quick written agreement protects both of you if anything is ever questioned.

Doing It Without Permission Is a Real Problem

Using an address you have no right to use, or listing one to hide who is really behind a business, is a different matter from a friend helping out. Business filings are signed under penalty of perjury, and in Florida a signer who knew the information was inaccurate can owe damages to someone who relied on it. How this is treated varies by state, so this is general information rather than legal advice.

The reverse happens too. If you find that your address was used for an LLC you do not own, you can contact the filing state's business division to report it. Colorado, for example, lists including an address in a filed document without the owner or occupant's consent as a complaint ground. Read the limits before you count on it, though: the same office says the complaint process is not for disputes with someone you know, such as a former partner, family member, or friend, and that a review plus a possible Attorney General referral can take several months. A borrowed address that went wrong with someone you know is usually a private legal matter. Either way, check whether mail in that business name is arriving for you.

A Cleaner Alternative: Your Own Business Address

Most people asking this question really want to keep their home address private without leaning on a friend. A business address of your own solves that without putting someone else's home on your filings or in front of a process server.

A professional business address keeps both your home and a friend's home off the public record.
Mail scanning means business mail and government notices reach you directly rather than through someone else's mailbox, while service of process still goes to your registered agent.
You control the address, so it does not disappear if a relationship or living situation changes.

Using someone else's address for your LLC can work for a mailing or principal address when you have their genuine permission, but it is not a fit for your registered agent unless they agree to serve, and doing it without consent invites real trouble. The person whose address you use is taking on your business and legal mail, which is a bigger favor than it first appears.

If the goal is privacy or simply a professional address, getting your own is usually cleaner than borrowing one. It keeps everyone's home off the public record and makes sure the important mail reaches you.
