Instructions for sending letters

Write the recipient’s name and address in the bottom right-hand corner. Enter the sender’s information in the top left-hand corner. You can find street addresses and postal codes in the postal code search.

Sending items abroad? Write the address according to the common practice in the destination country. However, write the country name in CAPITAL LETTERS. See the country-specific instructions. Select the recipient’s country in the menu below “Postal addressing systems in member countries and/or territories”.

Place the stamp on the top right-hand corner of the letter or postcard.

Place the stamp on the top right-hand corner of the letter or postcard and the Plus Sticker on the left of the stamp. The Plus Sticker can only be used in the Finnish mainland. If you’re using All-in-One envelopes or pre-paid postcards, place the Plus Sticker next to the payment indication.

Of course! Wrap the item in cardboard, bubble wrap or other suitable material for protection. Pack the item carefully so that the envelope and the content do not fall apart when dropped to the mailbox or during mechanical mail handling. Make sure that the content is not dangerous or harmful.



Check the maximum dimensions and weights for letters. For example, the maximum dimensions of a domestic letter are 25 x 35.3 x 3 cm and 2 kg.
 


Please note! If you want to send goods in a letter to outside the EU, register the content of the letter before sending. Specify the content also on the CN22 customs slip on the envelope.


Did you know that many ordinary products, such as nail polishes and perfumes, are easily flammable? Flammable items should not be sent by post.

Your item must not contain dangerous goods, objects or other prohibited substances.

If you want to send cash, securities, precious metals, jewels or other valuables, send them as an insured item. Insured items go through special security handling.

Check the country-specific bans and restrictions before sending items abroad.

Calculate the price or see the consumer prices.

You can buy stamps almost anywhere. Stamps are sold in more than 3,000 locations in Finland. In addition to postal outlets, stamps are available, for instance, at kiosks, grocery stores, bookstores and service stations.


You can also order stamps directly from Posti.

Yes, you can! The old 1st and 2nd class no-value indicator stamps are still valid as such. They have the same value as the domestic no-value indicator stamp. You can even use Christmas no-value indicator stamps (the snowflake symbols) all year round. However, pay attention to their value and add the necessary extra stamps.

You can check the current value of no-value indicator stamps in the price list.

Are you the sender?

We deliver standard domestic letters and postcards usually within four weekdays. Standard letters can’t be tracked, and if the letter has not unique tracking code, its detailed movements cannot be found out. If the letter is equipped with a Plus Sticker, we will deliver it in two weekdays. Item Tracking will show when the Plus Item has been delivered.

You can track the delivery trackable letters with the tracking in the Item Tracking. Check the delivery times of trackable letters in Posti’s delivery time inquiry.

In the case of an Insured Letter, Posti pays compensation up to the insured value. Therefore, you should mail all items of value as an Insured Letter. Normally, it’s not possible to verify afterwards the movements or delivery of a standard letter. That’s why it’s not usually possible to receive compensation for them. You can use Item Tracking to check when an item equipped with a Plus Sticker is delivered to the recipient.

The precondition of compensation is that we can establish that the damage occurred while we were responsible for the item. The occurred damage is verified by receipts. More information on compensation criteria and maximum amounts.
