An affordable Standard letter is suitable for mechanical sorting and it is delivered at the same speed as a Priority or Economy letter. When your letter item is suitable for Posti's mechanical handling, the Standard letter is the most affordable option. In addition to optical reading requirements, suitability for machine handling also sets some dimension, shape, material, color and content requirements for the letter item.

If the address is incorrect or obsolete, the Standard letter will go through address clarification and it will be delivered to the recipient's valid mail address without extra charge. If the correct address cannot be determined, the letter will be returned to you.
