The scheme, which included a priority and a standard postal service, was introduced in May 2010.
Beginning on 1 March, the 42p stamps will no longer provide a priority letter service, and will be replaced with 37p stamps.
The announcement comes following an Islandwide survey of 40,000 residents on the Jersey Post.
Chief executive Kevin Keen said: ‘The most common negative point was about the two-tier system. We were going to look at it anyway, as it has been complex to operate and it wasn’t very popular.’
‘With the majority of customer comments relating specifically to this system, there was no doubt that it had to be changed, which is what we are now doing.’
