P.O. Box – for small amounts of mail
The P.O. Box service is a convenient option for smaller businesses if the amount of incoming mail is not very large and the items fit in a locker that measures 400 × 532 × 170 mm (width × depth × height).
The P.O. Box service provides your business with its own P.O. Box and a P.O. Box address that is independent of your business’s street address.
You can choose your own locked P.O. Box at a location that suits you best.
Your mail will be delivered to your P.O. Box every weekday and you can pick it up whenever you want.
Example of a P.O. box address
A Posti P.O. Box address is made up of your business’s name, the P.O. Box number, a postal code ending in the number 1 and a city/municipality.
Company Ltd. P.O. Box 67 02341 ESPOO, Finland

Corporate Address – for businesses of all sizes
With the Corporate Address service, your business will receive a permanent P.O. Box address, and your business's mail will be delivered to the address of your choice. The service is suitable for situations where you need multiple P.O. Box addresses for different departments in your company, for example.
The Corporate Address is a P.O. Box address that is independent of your business's street address and does not involve a physical P.O. Box with its size limits.
Corporate Address is always accompanied by a separately agreed Pickup and Delivery service. With the service, you can receive letters and parcels to your preferred address every weekday.
