| New operational arrangements, The existing mail offices have been classified into Level 1 (L-1) and Level 2 (L-2) mail offices. There would be 89 L-1 and 244 L-2 mail offices under the new set up |
| All L-1 mail offices will close direct bags for each other. An L-1 office will also close bags for all L-2 offices as well as delivery post offices mapped/attached to it |
| All L-2 offices attached/mapped to it an L-1 office can close bags for that particular office. An L-2 office may also close bags for all other L-2 offices mapped to the same L-1 office if the need be. It will also close bags for all delivery post offices mapped to it. |
| An L-2 mail office would not close bags for any other L-1 office to which it is not mapped. Similarly an L-2 office will not close bags for any other L-2 office which is not mapped to the same L-1 office. However, there may be a situation where an L-2 office may require closing bags for an L-1 or L-2 office falling in the same circle or neighboring circle for transmission advantage. Circles should try to keep this number to the bare minimum to the extent possible. In all such exceptional cases, the circle concerned should furnish the list of such offices and destinations for which bag closing is required and seek approval of the Directorate. |
| Post Offices would prepare two kinds of bags (separate for unregistered and registered mail) for their parent mail office (L-1 or L-2 as the case may be), which would be as follows. |
