I've recently been sending a few letters and one of them has not been delivered yet, and I don't think I stuck the stamp in the top-right corner of the letter. So does it matter if a stamp is not stuck in the top-right corner of a letter and why are stamps frequently placed here on post?

  • Welcome to TSE. This question does not appear to be related to travel, but for what it's worth, each postal service sets its own standards for how to format letters and parcels for delivery, and by and large these follow international addressing conventions set forth by the Universal Postal Union (established in 1874 and now an agency of the United Nations). – choster Jan 17 '20 at 23:14

    Historically top-right corner may have been chosen because the majority of postal workers sorting the post manually were right handed. Not placing it in the standard location will delay delivery because the letter will not pass the automatic sorting process and will have to be sorted by hand throughout its journey. – Traveller Jan 18 '20 at 0:02

    You would do well asking this on the History SE because there’s a really good background to postage and international mail handling standards. – Moo Jan 18 '20 at 0:55

    I’ve just checked Wikipedia and UPU. Wikipedia has no content on the postage zone of an envelope. UPU is impenetrable both technically and in terms of clarity. – Samuel Russell Jan 19 '20 at 0:49
  • mind that the only (now deleted) answer to this question is off topic for this History.se but would have been on topic in the context of travel.se. – jwenting Jan 23 '20 at 5:49


When the first adhesive stamp (then usually called a 'postage label stamp'), the Penny Black, was introduced in May 1840, instructions were given to place the stamp above and to the right of the address. These instructions were printed on the sheets of 240 stamps by the printers Perkins, Bacon & Co. (an example can be seen here). The decision to do this was made by Sir Rowland Hill, the primary force behind the new postal system.

Rowland Hill decided as early as December 31st, 1839, that "Certain instructions as to the position of the stamp when used [were] to be engraved round the margin of the plate." On March 26th. 1840, he writes : "In the margin to the plates insert the following inscription — if possible once at each end and twice on each side of the plate....Place the label above the address and towards the right hand side of the letter.

Unfortunately, the above (otherwise detailed) source does not give his reason for this instruction, and neither do Hill's own The life of Sir Rowland Hill and the History of penny postage (1880), nor his daughter Eleanor Smyth's work Sir Rowland Hill; the story of a great reform (1907). An earlier publication by Hill, Post office reform: its importance and practicability (1837) mentions only the idea of putting the adhesive stamp on the back of the envelope. However, it seems most likely that Hill (1) was following precedent (albeit an inconsistent one) and, (2) gave the instruction as one of a number of decisions aimed at making the new postal system as simple as possible.


On the first point, precedent relates to the fact that handwritten postal charges, as well as franked letters, were most commonly (but not always) marked above and to the right of the address, as shown in the examples below:

The same can be found for the United States:

The Post Office Department issued its first postage stamps on July 1, 1847. Previously, letters were taken to a Post Office, where the Postmaster, clerk, or assistant would note the postage in the upper right corner.

Why usually the right side, not the left?

As noted in comments above, the use of the right part of the envelope is, in part, likely due to the fact that most people are right-handed. Note that, prior to the introduction of uniform postage rates for any distance within the country (see the 1839 Postage Act), the post master would have needed to see the address to determine the cost of sending the letter because a letter from London to Dover, for example. would have cost less to send than one from London to Leeds. Writing the cost in the centre or on the left of the envelope would likely mean the hand covering the address, making it difficult to read (and maybe double check) the address and write the postage rate at the same time. For a righthander to put the postage rate on the left is not a major hassle, but it is easier to put it on the right side. The fact that some letters have the postage written on the left side may reflect a small number of left-handed post masters.

Why usually the top, not the bottom?

The above, though, does not explain why the top right rather than the bottom right was most commonly used even prior to Rowland Hill's instructions. Again, practical considerations are the most likely explanations. First, under the old system, postage was post-paid, not prepaid, so the deliverer and receiver would need to check the cost at the point of delivery, before the letter could be handed over. As we tend to look at the top of an envelope (or sheet of paper) before the bottom, it seems logical to put the price at the top where it will be more quickly seen. A possible second practical consideration is that long addresses sometimes leave little space at the bottom of the envelope, and I would venture that the top right corner was/is more likely to have some empty space than the bottom right corner.


In the Bacon, Hill and Smyth works cited above, Rowland Hill was concerned that the new postage system would operate smoothly, efficiently and profitably in all areas. He paid a great deal of attention to detail, and it is likely that he realised that postal workers checking large numbers of envelopes for the new postage label stamps would be able to work more quickly if these stamps were (more or less) to be found in the same area of the envelope (i.e. the eyes would quickly learn where to expect to find the stamp at first glance). Thus, what had previously been the only most common location now became the standard - the top right hand corner.

In the US, there does not appear to have been an actual instruction to the public to place stamps in the top right corner. According to Daniel Piazza, Chief Curator of Philately at the Smithsonian National Postal Museum,

When postage stamps were first issued in this county in 1847, there appears to have been a great deal of confusion over how to use them and possibly also where to place them, at least for a time,...Placement was less important in the days when all stamps were hand-cancelled individually by postal clerks. With the introduction of high-speed cancelling machines starting in about the 1890s, the placement of stamps in the upper-right corner became more important to be as efficient as possible.”

(Note that the article which cites Daniel Piazza is somewhat misleadingly titled.)

As the postal reforms by Britain from 1839 had proved to be largely successful (and profitable), other countries mostly followed the British example, though it is clear that the preference for the use of the top right corner for prices and franking was already widespread in the US and many other countries.

Things can go wrong, even when people read the instructions...

As an amusing footnote, there was still some confusion about the placement of adhesive stamps in the UK despite Rowland Hill's best efforts. Shortly after their introduction, Hill related the following story:

While the stamps were still new that large section of mankind which never reads public instructions was occasionally at a loss where to affix the adhesive. Any corner of the envelope but the right one would be chosen, or, not infrequently, the place at the back partly occupied by the old-fashioned seal or wafer. Even the most painstaking of people were sometimes puzzled, and a certain artist, accustomed, like all his brethren of the brush, to consider that portion of his canvas the right hand which faced his left, was so perplexed that he carried to the nearest post office his letter and stamp, knocked up the clerk, and ... asked politely, " Which do you call the right hand of a letter?" "We've no time here for stupid jokes," was the surly answer, and the window shut again directly.
