Virtual Office vs PO Box: Which One Can You Register a Company At?
The short answer: a virtual office can be your registered company address in London, New York, Singapore and Dubai — a PO box, in most cases, cannot. Since 4 March 2024 Companies House has refused PO boxes as registered offices outright, US states bar them for registered agents, and Singapore's ACRA has never accepted them. A virtual office clears these rules because it is a street address at a real, staffed building: this catalog lists 155 of them across the four cities, with plans starting at $47 per month in New York.
What is a virtual address — and how is a PO box different?
A virtual address (or virtual office address) is the street address of a real, staffed business center that you license for your own use — on your website, invoices, bank forms and, crucially, your company registration. At Fleet Street, a Regus center in the City of London, reception staff sign for your post at a building with its own postcode, floors and suite numbers; the same model runs across all 83 London buildings in this catalog. Mail can be held, scanned or forwarded, and most plans add pay-per-use meeting rooms.
A PO box is the opposite: a numbered, locked compartment inside a post office, addressed as "PO Box 5847" rather than a street and floor. Only the national postal operator — USPS in the United States, Royal Mail in the UK, SingPost in Singapore — delivers into it, so a FedEx or DHL courier physically cannot reach it. The format announces itself, too: any registrar, bank or customer can see at a glance that there is no office behind the number.
The two products are regulated differently as well. In the US, a virtual address provider operates as a Commercial Mail Receiving Agency (CMRA), and USPS requires each customer to file Form 1583 — "Application for Delivery of Mail Through Agent" — backed by two forms of ID, one with a photo, before the center may accept a single letter. That paper trail is precisely why banks and registrars treat a staffed virtual office differently from an anonymous box.
Company registration: the legal test in four jurisdictions
In the UK, the question was settled on 4 March 2024, when the registered-office provisions of the Economic Crime and Corporate Transparency Act 2023 took effect: Companies House now requires an "appropriate address" where statutory mail will come to the attention of someone acting for the company and delivery can be acknowledged. A PO box fails that test by definition; a staffed center passes it. Non-compliant companies are moved to a default address and risk being struck off. All 83 London virtual offices in this catalog are addresses of exactly this kind, from $74 per month.
In the United States the block sits at state level: nearly every state requires a registered agent at a physical street address where legal papers can be served in person during business hours, and a PO box is expressly barred from that role. Many states apply the same logic to the principal address on formation documents. A New York virtual office from this catalog starts at $47 per month, with a median of $103 across 22 buildings — including Regus at 260 Madison and Signature at 250 Park Avenue.
Singapore is the strictest of the four. Section 142(1) of the Companies Act 1967 requires every company to maintain a local registered office that is open and accessible to the public for at least 3 hours during ordinary business hours on each business day, and ACRA does not accept PO boxes at all. A staffed Regus center such as One Fullerton on the Marina Bay waterfront satisfies the 3-hour rule by default; the catalog lists 34 Singapore buildings from $77 per month.
Dubai ties the trade license itself to the address. The Department of Economy and Tourism (DET) requires mainland licenses to sit on a tenancy registered in Ejari, and a desk in a RERA-approved business center qualifies, while free zones such as JAFZA bundle a flexi-desk address into the license package. Among the 16 Dubai virtual offices here (from $71 per month), Regus BCW inside JAFZA View 18 & 19 covers the free-zone route and the Downtown center covers the mainland one.
Where a PO box fails even when it's legal
Banking is the usual second wall. Know-your-customer teams verify an operating address, and a box number invites requests for proof of premises that a street address rarely gets. A virtual office at a named tower gives compliance something concrete to check: Signature's center on the 37th floor of One Canada Square in Canary Wharf has a reception that answers the phone, which is exactly what a verification call is looking for.
Delivery and perception follow the same line. FedEx, UPS and DHL deliver to street addresses only, so bank cards, samples and signed contracts cannot land in a postal box; and on a proposal, "One Fullerton, Singapore" or "250 Park Avenue, New York" reads very differently from a five-digit box number. With city medians of $103–$168 per month in this catalog, that upgrade costs less than most software subscriptions.
What it costs in London, New York, Singapore and Dubai
Across the 155 buildings in this catalog, entry prices sit in a narrow band: New York from $47 per month (22 buildings, median $103), Dubai from $71 (16 buildings, median $155), London from $74 (83 buildings, median $161) and Singapore from $77 (34 buildings, median $168). The from-price typically covers the address itself with mail handling; live phone answering and meeting-room hours are what push a plan toward the city median.
If you need the address for registration rather than image, start with the cheapest staffed building in the right jurisdiction — the legal tests care about the staffed desk, not the skyline. A $47 Manhattan plan satisfies a state's registered-address logic the same way a $161-median London one satisfies Companies House.
FAQ: virtual office vs PO box
Can you register a company at a PO box?
In the UK, no — Companies House has required an "appropriate address" since 4 March 2024 and moves offenders to a default address pending strike-off. In Singapore, no — Section 142 of the Companies Act demands premises open to the public 3 hours a day. In the US, a PO box cannot serve as your registered agent's address in any state, and most states refuse it on formation documents too. A staffed virtual office passes all three tests.
What is a virtual address?
A virtual address is a real building's street address licensed to your business, with on-site staff who receive, scan and forward your mail — in the US the arrangement is regulated through USPS Form 1583 and the CMRA framework. Unlike a PO box, it carries a street-and-floor format that registrars accept: the 155 buildings in this catalog, run by operators like Regus, Spaces and Signature, all work this way.
Is a virtual office more expensive than a PO box?
At the counter, yes — a bare postal box costs less than the $47–$77 monthly entry prices in this catalog. But a box cannot hold a UK, Singapore or US company registration, so incorporating founders end up buying a compliant address anyway. One street address at, say, MBFC Tower 3 in Singapore replaces the box, the registered office and the courier delivery point in a single line item.
