Service level
The service level determines how quickly the item is delivered. For domestic envelopes, choose the faster Priority or the more affordable Economy. Letters sent abroad are delivered using the Priority speed.
Domestic Priority Letter
Priority Letters are usually delivered by the third business day from the mailing date. If a Priority Letter contains goods, for example, or is unsuitable for machine sorting, the item will be directed to additional sorting, and the delivery speed will be one day slower.
Domestic Economy Letter
Economy Letters are usually delivered by the fourth or fifth business day from the mailing date
International Priority Letter
Priority letters are delivered all over the world the weekday following the mailing or, otherwise, on the first available connection following their mailing. The items are delivered to the destination country primarily via air mail and delivered to the recipient in the destination country within the timeframe for delivery defined by the destination country’s postal operator.
