Franked mail is done by a machine. It does not have a stamp on. The machine is bought by a business or company and the cost of the postage is bought at the post office and input into the machine. You probably get loads of letters with no stamps but with a red circle saying how much the letter has cost. Hope this helps.
Franking is process used by businesses.Essentially some business make a deal with mail companies, whereby they pay a single fee for all the mail that goes fromthem. Sometimes its more, sometimes less than the fee they pay, but instead of stamping every letter they pay a single regular fee for all their mail.These companies get franking machine, which is essentially like a printer. You put letters through them, and the letters get stamped with a postage mark and code which recognises the letter as having come from that company.Those boxes that say franked only refer to letters that have been stamped in this way by a re-paid franking machine by a company.
