Royal Mail Hell Bent On Confusing Its Customers With International Business Mail “Large Letters”

Royal Mail with many of its UK customers still struggling to get to grips with its size based pricing (PiP or Large & Standard Letters – introduced in 2006) have decided to rebrand what they formerly called ‘International Flats’ as ‘Large Letters’.

So far so good you might think.

However, for some reason the rules & size allowances for International Large Letters are not the same as those for UK Large Letter postings.

If you are a user of RM’s International Services and a bit confused you may be interested to know that we produce a range of boxes for the new International Large Letter Sizes
