A business address in downtown Modesto.
Establish a professional business address, manage your mail securely, and boost your business presence — without the overhead of a full office.
What is a virtual office?
A professional business presence, minus the overhead.
A virtual office gives your business a real, professional address without the expense of leasing a traditional office. Maybe you no longer want clients seeing your home address when they look up your company, maybe you want to expand your presence into the Central Valley, or maybe you just need a secure location to accept important mail and packages on your behalf.
At Nine3One, you get the credibility of a downtown Modesto location plus the support of an onsite team to manage your mail while you work from anywhere. It's a great fit for running a remote company, launching a new business, or simply upgrading to a better mailing address — easy to stay professional and organized.
Why choose a virtual office at Nine3One?
Nine3One isn't a PO box or a faceless mail center. We're a boutique coworking space with an onsite team, real offices, and beautifully designed meeting rooms.
That means:
- Your business address is legitimate and professional — usable for licensing, bank accounts, websites, and business cards
- Your mail is handled by real people, not lockers, and is stored securely for you
- You have a physical place to work or meet whenever you need it
- We're centrally located in downtown Modesto, steps from City Hall and easily accessible from across the Central Valley — including Turlock, Ripon, Manteca, and Stockton — making it an ideal solution for businesses operating locally or remotely throughout California
It's flexibility — without sacrificing credibility.
Getting Started
How does it work?
Just a few steps and you'll be ready to use your new business address.
Sign up for your plan
Choose the virtual office membership that fits your needs. We offer a few options designed for different businesses.
Complete Form 1583
After signing up, you'll complete a USPS Form 1583 and upload your ID. This registers your new address with the post office and allows us to accept mail on your behalf.
Verify with an online notary
Once your form and IDs are submitted, you'll be connected with an online notary who verifies your identity and finalizes your Form 1583. As soon as we receive that confirmation, your mailbox is active.
