Notes about the codification

The constitution of the MSAR, on 20.12.1999, has introduced some changes in Macao’s philately, specifically in the issuing Postal Administration’s designation and in the identification code of stamps and souvenir sheets.


In the first case, the designation “República Portuguesa” was replaced by “Macau, China”, on the second case, the issue “Macau Retrospective”, in 19.12.1999, marked the ending of the codification series in use, with the last codes S193(4/1), S193(4/2), S193(4/3) and S193(4/4), for stamps and S194(1/1), for the Souvenir Sheet.


By terminating this series, it offered an opportunity to create new series and codes, not only for stamps and souvenir sheets, but also to other philatelic products, like first day covers, booklets, information brochures, commemorative envelopes, postcards, etc., and also to all the postmarks associated with new issues, commemorative cancellation services and exhibitions.


All the new series have started with the number 001 and are sequential.


The decision by Macao Post and Telecommunications of creating a code system, presented here, had the following two objectives:
  • Decrease the possibility of falsification of the coded products.
  • Offer the collectors an easy and fast possibility of, at any time, knowing if their philatelic collections have been complete or not.

As far as the first objective is concerned, to decrease the falsification worldwide, the Universal Postal Union, in conjunction with the World Association for the Development of Philately (WADP), has also created a worldwide numbering system (WNS), to which the Macao Post has joined after January 1st, 2002, being the approved code represented by MO xxx yy, in which MO represents the Macao Postal Administration, xxx represents the numerical sequence started by 001 and yy represents the year of the issue.


The codes printed on the Macao Post and Telecommunications' philatelic products are generally composed by a literal part (S, B, … etc) identifying the product, and by a numeric sequence (xxx = 001, 002, 003, etc.) identifying the order.


As for stamps and souvenir sheets, there is also an additional indication (y/z), in which the variable “y” shows the number of stamps in the series of that issue, and the variable “z” showing in the series of stamps, that specific stamp (See the following example).


THE CODES USED ARE AS FOLLOWS
Issues (Stamps) S xxx(y/z)
Souvenir Sheets B xxx(y/z)
First Day Cover, w/stamps ENA xxx
First Day Cover, w/Souvenir Sheets ENB xxx
Commemorative envelopes issued by Macao Post and Telecommunications Bureau ENC xxx
Commemorative envelopes issued by other entities ENX xxx
Information Brochures PGL xxx
Booklets with stamps BLK–S xxx(y/z)
Booklets with Souvenir Sheets BLK–B xxx(y/z)
Postcards of new issue BPL xxx
Commemorative Postcards issued by Macao Post and Telecommunications Bureau BPC xxx
Commemorative Postcards issued by other entities BPX xxx
New issue, Commemorative or Exhibition Postmarks C xxx

In order for collectors and readers to understand better the use and meaning of the codes, here are some examples:
