It will cost more to send mail from Guernsey from next month.
Guernsey Post is putting up rates from 4 April 2022.
A local stamp is rising by two pence to 52 p and a UK one will be six pence more at 79p.
The price of a letter to Europe will rise by 10p to £1.10 and postage to the rest of the world will be £1.35, up 15p.
The service says it has had no choice but to pass on increases announced by Royal Mail and other operators.
Guernsey Post says it has frozen charges for large parcels to all destinations, as well as some international Large Letters.
“The scale of the increases recently announced by Royal Mail and the same for the charges which we are indirectly required to pay to other postal administrations around the world are far greater this year than we have ever experienced before.
Consequently, and regrettably, we have been left with very little choice other than to pass on most of the increase to our customers.
All of the additional revenue generated by these tariff changes for mail destined outside of the Bailiwick will flow through to pay for the increase in the charges applied to Guernsey Post.
In addition to the increases applied by other postal administrations we have also experienced above inflation increases in sea and air transport costs, much of which we are absorbing." - Boley Smillie, Guernsey Post Chief Executive.
