Coded postal obliterators
Coded postal obliterators are a type of postmarks that had an obliterator encoded with a number, letter or letters, or a combination of these, to identify the post office of origin. They were introduced in the United Kingdom of Great Britain and Ireland in 1843, three years after the first stamp was issued. They became common throughout the nineteenth century but very few remained in use until the twentieth century.
The practice of cancelling a stamp on a letter with a device to prevent reuse and applying alongside, or on the reverse of the article, a dated stamp including the post office name, began in 1840 when postage stamps were introduced in the United Kingdom.
Soon, in many countries, various systems developed where the obliterator had a code identifying the post office of origin. Most such codes were enclosed within a design of dots, rays, bars or concentric circles or ovals to ensure the effective cancellation of the stamp. Similar designs without an enclosed code are known as dumb or mute obliterators. Later the duplex canceller with the datestamp on the left and the obliterator on the right came into common use. Coded obliterators were used throughout the nineteenth century but few persisted to the twentieth century.
Coded obliterations are collected by philatelists and rare examples can command high prices.
Postal administrations which used coded obliterators include:
United Kingdom and colonies
The first coded obliterators were numerals within a Maltese cross design used at the London mail centre from 1843. From 1844 distinctive and different barred designs were introduced for England, Scotland and Ireland. England and Wales numerals were within a circle of bars, while Scotland used a rectangular form and Irish codes within a barred diamond. Codes corresponding to London postal districts e.g. W21 were also used.British Post Offices abroad

used a series of numerals within three concentric circles. Some duplex obliterators were used. They were all withdrawn in 1873.France
The obliterator was as a diamond or trapezoidal shaped grid of dots, measuring about 20 millimeters on each side, with a set of numbers at its center. The number consisted of anywhere between one and four digits, and was unique to the post office that used it. For this reason, such numbers are sometimes referred to by philatelists as "town numbers."Two main types of the losange were used, the "losange à petits chiffres" from 1852 to 1862, and the "losange à gros chiffres" from 1862 to 1876. Distinguishing the two is based largely on the size of the numbers and the size of the dots in the cancel. The dots are noticeably smaller in the "losange à petits chiffres" and its numbers measured approximately 4 millimeters high. Town numbers between 1 and 4494 are documented. Town numbers from 3704 to 4018 and 4222 indicate use at a French Post office abroad.
The "losange à gros chiffres" obliterator had numbers twice as big being nearly 8 millimeters tall. Since the overall size of the cancel remained the same, a larger portion of a large number obliterator consisted of the town number. The list of numbers used increased as the number of new post offices opened, with numbers known up to 6449. Town numbers 2387 and from 5079 to 5156 were those assigned to French post offices outside continental France.
