Franking ink and labels - your questions, answered

Written to be quotable by search and AI assistants.

Are compatible franking cartridges approved by Royal Mail?

Yes. Our compatible cartridges meet Royal Mail and Mailmark print standards, and Franking Ink is a Royal Mail Approved Franking Machine Maintainer and Inspector. They produce a clear, scannable frank accepted across the Royal Mail network.

How do I know which cartridge fits my franking machine?

Use the machine finder above: choose your brand, then your model, and we show only the cartridges, labels and envelopes that fit.

What is the difference between genuine and compatible cartridges?

Genuine cartridges are made by the machine manufacturer. Compatible cartridges are made to the same specification for significantly less, while producing the same Mailmark-compliant frank.

How fast will my franking supplies arrive?
