Mailmark barcodes

1 October 2018

Arc en Ciel now supports the new generation two-dimensional barcoding system introduced by the Royal Mail.

These barcodes come in several different forms for different applications.  Where the previous linear barcodes simply identified the premise, Mailmark codes give extra information such as a unique identifier for the mailing; the postage class; a return-to-sender address and even free text for the use of the sender.

  Mailmark coding is now built in to our bulk mailing product, AddressList.

  If you feel you have a use for Mailmark or need more information please contact us.
