Registered Address in Austria: What It Is and Why It Matters.
No company without a registered address: it appears in the company register, in your imprint and on every official letter. This guide explains what makes an address valid for service of documents in Austria, why a PO box does not qualify and what to check before choosing a provider.
01The basics
What is a registered address in Austria?
A registered address (in German: ladungsfähige Adresse) is a physical address at which documents can be legally served: a real location with a door number where mail actually arrives and can be accepted. A PO box is not a registered address.
The concept comes from the rules on service of documents: at this address, a summons or an official document must be deliverable in a way that makes the delivery legally effective. That requires a physical place clearly attributable to the company or person: an office, business premises, or a staffed location with a letterbox and a company nameplate.
For companies in Austria, the registered business address is therefore more than a mailing address. It is the legal anchor of the company: mail from courts, the tax office and public authorities counts as delivered here, even if nobody opens the door in person. A company that is unreachable at its registered address risks missing deadlines without ever having seen the letter.
Important: registered does not mean you have to work there. The address must be real and reachable, not your daily workplace. This is exactly why professional business address providers with a real location work, while pure letterbox setups and PO boxes do not qualify.
02Where it is mandatory
What you need a registered address for.
Three contexts strictly require a registered address. All three affect practically every business in Austria, from sole traders to a GmbH.
Company register
Every registered company needs a business address in the Austrian company register (Firmenbuch). It is publicly visible and must be an address where documents can be served. Without it, a GmbH will not be registered at all.
Imprint
Websites, newsletters and business stationery require an imprint with an address where the company can be reached. Publishing a private home address there is something many founders rightly want to avoid.
Official mail
The tax office, social insurance, courts and administrative authorities serve documents to the registered business address. Many of these letters carry deadlines: if you do not collect them, the deadline still runs, because the delivery counts as completed.
03The most common misconception
Can a PO box serve as a business address in Austria?
No. A PO box is not a registered address and is accepted neither for the company register nor as the sole imprint address. It is merely a pickup compartment at a post office, not a place where a company can be reached.
The difference is fundamental: a PO box is a collection facility operated by the postal service. Nobody can serve a summons there, nobody can ring a bell, and there is no door number attributable to a company. A registered address, by contrast, is a physical location with a street number and a door where documents arrive and can be accepted.
In practice this means a PO box can complement a registered address, for example for uncritical advertising mail, but it can never replace one. Stating only a PO box in the company register or imprint leads to problems at registration and risks formal objections.

04Understanding official mail
What happens to RSa and RSb letters at a rented business address?
Both types may be collected by anyone holding the recipient’s postal power of attorney. In the 1010.works Premium plan we collect RSa and RSb letters for you under a postal power of attorney. Only items marked “Nicht an Postbevollmächtigte” (not to be handed to authorised representatives) are delivered by the post exclusively to you in person.
RSb is the Austrian category of official letters delivered against signature where a substitute recipient may sign. Typical RSb mail comes from the tax office or administrative authorities.
RSa is the category of letters delivered into the recipient’s own hands. Substitute delivery to housemates, relatives or employees without authorisation is excluded. Delivery may be taken by you personally or by someone you have granted a postal power of attorney.
At 1010.works we receive the collection notices for RSa and RSb mail in every plan. In the Premium plan we collect the held letters from the post office for you under a postal power of attorney; with Basic and Plus you collect them yourself. The only exception are items marked “Nicht an Postbevollmächtigte”: the post hands these exclusively to you in person.
05Vetting providers
What should you look for in a registered address provider?
Check five things: a real physical location instead of a letterbox, transparent pricing, a clearly defined mail process, a postal power of attorney for RSa and RSb mail, and short notice periods.
01
A real location
The address must be an actual office or business premises you can walk into. Pure letterbox addresses without a staffed location put the validity of the address at risk.
02
Transparent pricing
The total price including mail reception, scans and forwarding should be public before you sign, with no quoting phase and no hidden surcharges.
03
A clear mail process
How do you learn about new mail, how fast is it scanned, how does pickup work? A combination of digital scanning and self-pickup at flexible hours is the benchmark.
04
Power of attorney for RSa and RSb
A provider holding your postal power of attorney can collect official RSa and RSb letters from the post office for you. Ask whether this is offered and which plan includes it.
05
Notice periods
Monthly cancelability protects you if your needs change. Long minimum terms are unnecessary for a business address and usually benefit only the provider.
