There are several ways to date postcards that are seemingly undated. This page provides a few general methods for determining a time period or date for postcards.
GENERAL POSTCARD CHRONOLOGY
Postcard producers printed cards that followed the current trends of postcards. Dates can be approximated by the material and design of a postcard. Our Postcard History page provides information about these general trends. For example, a card printed on linen was most likely produced between 1930 and 1945. However, it is important to remember that these dates and time periods are not concrete—they are only generalizations of trends in the postcard industry.
The rate of postage for postcards has changed throughout time and can be used to find an approximate date for postcards. Not all postcards have the required postage amount printed on them, so this method can only be used in instances when the postage is known. The following list is postage for postcards mailed within the United States.1

*The postage rate for most government-produced postcards was $0.01. However, depending on which government-produced postcard it was, the postage could range between $0.01 to $0.04.2 The postage for privately produced postcards was $0.02. This rate for privately produced postcards went down to $0.01 on May 19, 1898, with the passage of the Private Mailing Card Act.
In the early stages of postcard production, government-produced postcards varied in size, depending on the type of postcard.3 Privately produced postcards, also known as private mailing cards, did not need to adhere to the government restrictions. On June 1, 1878, the General Postal Union, an international postal organization, signed a new treaty, changing its name to the Universal Postal Union. This treaty set the maximum size for postcards produced by governments of member nations at 3.5 x 5.5 inches.4
The Private Mailing Card Act of May 19, 1898, stipulated that private mailing cards measure 3.25 x 5.5 inches. After 1901, postcards typically measured 3.5 x 5.5 inches, although variations in size exist. In the 1960s, some printers began producing 4 x 6 inch postcards. Today postcards vary greatly in size and shape, so it is more difficult to use size to date them—but if the size or shape of the postcards differs from the above standards, it’s safe to assume that they were probably made within the past few decades.
CURT TEICH POSTCARDS
Curt Teich & Co., a postcard printing company, operated from 1898-1978 and specialized in view (postcards that have scenic views) and advertising postcards. Curt Teich was the largest volume printer of these types of postcards in the world from the 1920s to the 1940s. Many of the postcards we have at the Archives were printed by Curt Teich & Co. It is easier to give Curt Teich postcards an approximate date because the postcards’ print numbers correspond to production years. This dating guide compiled by the Curt Teich Archives, a wonderful wealth of images and information, provides detailed information about the postcard print numbers and dates.
