PRIO letters for business clients

Use our PRIO letter mail service for quick and reliable shipping of business mail such as quotes, invoices, payment reminders, documents, contracts and small merchandise. More than 95% of PRIO items are delivered on the following business day.

Posting locations

We have myriad posting locations throughout Austria, including more than 1.800 Österreichische Post service locations as well as 200 self-service areas where you can post your items. PRIO items can also be posted by placing them in one of our 16,000 letterboxes.

For posting larger volumes (starting at approximately 2,500 items), we recommend our service locations for large volumes and our distribution centres to ensure high-speed processing.

For those highly important PRIO items, registered mail as well as other additional services such as deliver to addressee only, advice or receipt, do not deliver to persons authorised to receive mail, etc. are available.

You have the following options to pay for postage for your PRIO letters:

  • Postage paid in cash:
    Recommended for large volumes.
    Enter your customer information, number of items and weight in your PRIO letter posting list or use our software
  • Paying for postage with a franking machine:
    Convenient and easy postage payment, recommended especially for daily business mail
  • Stamps:
    Great for getting recipients' attention; they add a "special touch" to your items

How to find the right rate category (letter S, letter M, packet S, packet M) for your letter mail items:

  • Item's weight
  • Format (use our sizing template to determine the format)
  • Machine processability yes/no – non-machine processable items are assigned to the next higher rate category

For more information about machine processability of your letter mail items, please read our correct addressing brochure. Alternatively, you can have your item layout checked by your customer advisor, our service centre 0800 212 212 or online.
