There are two main classes of Addressed Admail in Canada. These are "NDG" and "LCP".
NDG stands for National Distribution Guide. This is a manual guide, prepared by Canada Post. With this guide, bulk mailers can sort mail at several levels. However, the lowest sort level is only direct to postal station. Although there are savings when you compare the bulk NDG rate to first class rates, the NDG rates are generally higher than LCP rates.
LCP stands for Letter Carrier Presort. LCP mailings are sorted with specialized computer software. This software will attempt to create letter carrier bundles wherever possible. In these cases, the bundles can be given directly to a letter carrier for a particular route. As the sort breakdown is much finer with LCP, mailers using this service frequently enjoy significant savings as compared to the NDG service.
