From 7 April the price of sending a letter to the UK will increase from 68p to 73p.
Guernsey Post has announced postal rate rises from next month.
It will cost you more to send a letter out of the Bailiwick.
There's a 5p increase for posting letters to the UK, and if you want to send a letter to Europe, it will cost you 15p more at £1.
Sending a letter to the rest of the world will rise by 25p to £1.20.
There will be no change in the postage for local letters, which will remain 50p.
"We have been able to freeze some of our prices including most Bailiwick rates, all of the medium parcel rates to the UK and some European parcels rates.
"However, Royal Mail are implementing significant prices increases for mail to the UK and because of reforms to the charging mechanisms applied by other countries the cost of sending international mail has increased by 40% over the last twelve months.
"We will be absorbing 50% of the increase in international charges but reluctantly we must pass the rest on to our customers." - Guernsey Post Chief Executive Boley Smillie.
