1847usa.com is an identification site for U.S. Postage Stamps and is free for all to use, subject to copyright restrictions. Please feel free to email 1847usa if you are unsure in the identification of your U.S. stamp or to report errors and omissions.

Special IDENTIFIERS for the 19th Century stamps have been added, one for the classic stamps, 1847-1869 and one for the Bank Notes, 1870-1890. Commemmorative stamps after 1970, revenue stamps, possessions and postal stationery are not covered. Regularly issued stamps, sometimes refered to as "definitives", are included through 2000. Please visit the LINKS page for links to websites that cover modern commemoratives.

For information on stamp values, please see the Scott Specialized Catalogue of U.S. Stamps and Covers.. Keep in mind, condition and centering are often more important in determining a stamp's value than the Scott number alone and for this reason, PSE's Price Guide is highly recommended.

You are encouraged to use 1847usa.com as a starting point and to seek information from other sources as well, in particular by seeking out the suggested additional readings at the bottom of many of the identification pages.
