Mã Bưu Điện
Mã Bưu Điện (Tiếng Mẹđẻ: 馬郵電; Postal Code) is the Qwehyongine postal code system. It is officially abbreviated to MBĐ but is often written incorrectly as MBD. As part of the modernization that took place after the Qwehyongine Spring in 1942 and the takeover by the republican government, the President Xầm Đào Nhiếp ordered for a new postal code system. Formulated and put into place by the Qwehyongine Republican Postal Service in 1943 using 1 alphabetic character and 4 numerical digits, it was expanded in 1999 under President Hoàng Lưu to use three alphabetic character and five numerical digits.
A full postcode (Mã đầy đủ, 馬菭都) is a postal code that refers to an entire Prefecture, which uses a revised version of the 1942 system with only two numeric digits rather than four. A Sub-Postal Code (Mã bưu chính nhỏ, 馬郵正𡮈; lit. Small Postal Code) is a code that refers to a Second Level division that uses the 1992 system. Full postcodes are only to refer to Prefecture Postal Centers, and are normally not used for sending parcels out.
The structure of a full postcode of the revised 1942 system uses a single alphabetic character. The single alphabetic character is the first character of that Region. However it is mandated normally that the postal service replace the alphabetic character with the first Tiếng Mẹđẻ character of a region's name e.g. T turns to 徵 (Trung Metropolitan Region), L turns to 老 (Lão Region). The alphabetic character/Tiếng Mẹđẻ character is then followed by two numbers indicating the Prefecture. If two regions share the same first character, the two numbers will indicate which Prefecture it is indicating e.g. T01/徵01 and T16/守16 with 徵 referring to the Trung Metropolitan Region and 守 referring to the Thủ Region.
The structure of a Sub-Postal Code of the 1992 system uses three alphabetic characters. The three alphabetic characters are the first three characters of the Prefecture's name. Unlike the revised 1942 system that substitutes alphabetic characters with Tiếng Mẹđẻ characters, the alphabetic characters are normally not substituted to prevent confusion between the two postal codes. The next two digits indicate the Ward, in which the final three digits indicate the Commune.
Normally, every Ward or Commune will have their own Postal Distribution Center, as it is seen as bad luck to have non-paper items appear in Orthodox Qwehyongine Culture on one's property that are unnatural or man-made without a person's presence. The only heterodox exception to this is the Trieu Island Region, which does not follow this custom. It is also against the Republican Postal Service rules to use a specific address to deliver, and specific addresses are used only for verification purposes. Universities will also normally be given their own communes in which the state provides a Postal Distribution Center to the university. Despite the previous custom being considered unorthodox, this is the case in the Trieu Island Region, with communes that have universities in their designated borders following Orthodox Qwehyongine Culture with non-paper items appearing that are unnatural or man-made without a person's presence.
