On this page, you will find instructions for sending letters as a contract customer – both in Finland and abroad.
How to start sending
Write the recipient's name and address on the envelope. Also write the sender’s information on the envelope for possible return of the item.
Place the corporate letter's payment indication or stamp in the top right-hand corner of the envelope.
There are also specific places for other indications and identifiers. As Posti uses automated optical reading of the address information on mailed items, the information must be in the correct locations on the envelope. Correct addresses and correct address markings ensure that the item is delivered to the recipient without delays.
Items indicated on a mailing list must include a Port Payé payment indication (PP) for Economy or Priority letters according to Posti’s instructions and the selected delivery speed. Provide the mailing batch information, such as the payer, product number, quantity, zone, and unit or total weight as well as mailing location using an electronic mailing list.
Pack the letters in boxes with the address information facing the same direction. Large, small, and international letter items must be packed in separate boxes. Small quantities of items can be packed in the same box by, for example, using a rubber band to make separate bundles.
Attach either a covering letter or a control label of an electronic mailing list with the mailing list number to each shipment lot. Remember to sign the electronic mailing list as completed before delivering items to the posting place.
The primary posting place is the Helsinki or Kuopio postal center and the posting time is 5:00 p.m. at the latest. One (1) working day is added to the delivery time for items mailed at terminals. If you are using the Pickup and Delivery Service, please make sure that the items are delivered to the posting place by the last posting time. You can drop off batches of fewer than 100 pcs at a Posti service point or a corporate service point. The items must not be dropped off in a mailbox.
If you are using the Sorting Service, an electronic mailing list will automatically be created for your mailing batch.
Learn more about the Sorting Service which makes preparatory work easier and provides clear and up-to-date mailing instructions.

Download payment indications and instructions for use
Please note: The postal company in accordance with the Postal Act is Posti Distribution Ltd from January 1, 2023. However, Posti Ltd's payment indications will not expire and they can still be produced with a franking machine. There will be no time limit for using printed envelopes.
Franking machine
A franking machine makes mailing simpler and facilitates cost tracking.
This is how to start using a franking machine
Get a franking machine from a retailer. Franking machines are sold and leased by Azolver Suomi Oy (Pitney Bowes) and Quadient Finland (Neopost Finland) and their authorized retailers.
After you have bought or leased a machine, the device vendor notifies us.
Immediately after that, we will send you the order confirmation and service activation notification.
Payment of the operating assets
Pay the desired amount as the machine’s operating assets in the Franking Machine service through Posti’s service channels or into our account at Nordea, OP cooperative bank or Danske Bank. The account numbers and the reference number can be found in the activation notification or on the first page of the transaction breakdown. A device-specific reference number obtained from us must be used in bank transfers.
Danske Bank
BIC: DABAFIHH
Account number (IBAN): FI40 8000 1600 0105 82
Nordea Bank
BIC: NDEAFIHH
Account number (IBAN): FI08 2333 1800 0121 32
OP cooperative bank
BIC: OKOYFIHH
Account number (IBAN): FI71 5000 0120 2018 34
Once the operating assets you paid have been transferred to the top-up center of the device supplier, top up the payment to the franking machine. The balance can also be topped up in several instalments. You can view your balance with a balance query or a zero top-up. In the case of any problems related to the top-up, please turn to the importer or the top-up center. Quadient Finland Oy (Neopost Finland); tel. +358 (0)9 2532 0200 and Azolver Suomi Oy (Pitney Bowes); tel. +358 (0)9 6824 060
We will provide you with a transaction and product monitoring breakdown once a month.
Topping up the operating assets
You can top up the desired amount of operating assets into the franking machine from the top-up center, but only up to the amount stored on the account. After the operating assets run out, the franking machine is locked automatically.
Usage data from the franking machine is automatically transferred to us with each top-up event. Please make sure that the franking machine is regularly connected to the top-up center in order to deliver the necessary usage data to us and a transaction statement to you.
Exceptional top-up
If you have the right to exceptional top-up, you may top up a supported franking machine using a maximum sum of the credit limit specified in the agreement appendix.
An exceptional top-up must be paid to the bank account specified by us within five (5) weekdays from the exceptional top-up.
Consecutive exceptional top-ups are not allowed and an exceptional top-up may not be the first top-up on the machine.
We will charge a service fee in accordance with the franking machine price list for exceptional top-ups. Posti reserves the right to amend the terms of use for exceptional top-up.
The transaction statement contains an overview of the payments and top-ups made on the franking machine as well as a product monitoring report. You can track the number and total cost of the products paid for with the franking machine. Product monitoring requires a scale connected to the franking machine, a valid price memory and a top-up at least every two months, during which the product information is transferred to us.
The top-up may also be a zero top-up or balance query (further information is provided by the importer or supplier of the franking machine). An electric transaction statement is delivered to you once a month free of charge.A transaction statement will not be delivered if there have been no payments or top-ups.
If you choose to terminate the use of the franking machine, you must inform us using the notice of termination below. We will send you a confirmation of termination and, if necessary, instructions for delivering the machine to the importer.
If the franking machine is used in a way that violates the product terms, Posti may terminate the right of use immediately. If the franking machine has not been topped up in the past 12 months, we have the right to terminate the use of the machine without a period of notice. If there are operating assets left on the machine’s account, Posti will request a bank account number from the customer in order to return them. In cases where the customer cannot be reached, the customer can receive the assets left on the closed franking machine’s account upon request.
Postmarking errors
Under certain conditions, we will refund postmarking errors made with a franking machine. Postmarking errors will be refunded if their value is EUR 20 or more and if they are less than six months old.
Please note that Posti does not refund the following postmarking errors:
postmarks removed from envelopes and postcards
stamps removed from parcel items and cases, unless enough of the package is left around the stamp
stamps removed from sticker sheets
mirror images of the stamps
unclear or incomplete stamps
postage reply mail stamps
stamps on undeliverable items
postmarking errors that cannot be verified
In order to receive compensation for a postmarking error, proceed as follows:
Pack the form and the incorrect postmarks securely together with their envelopes in one shipment.
Mail the item to:
Posti Ltd
Franking machine services
ID 5009023
00003 REPLY MAIL ITEM
The postmarking error refund is subject to the charge defined in the price list. Verified postmarking errors are added to the operating assets of the franking machine, from which the amount can be topped up into the machine.
Underpaid items
Underpaid mail items are handled and priced according to the franking machine price list valid at that moment. If this results in additional work or other costs, the customer will be charged a handling fee and/or the costs incurred according to the price list. Posti has the right not to accept underpaid items for delivery.
