Postal stationery

 Under construction 

Postal stationery are prepaid stamped envelopes, cards and other specialty items sold by post offices. They are usually prepaid with major types being:
 * Lettercards
 * lettersheets including aerogrammes
 * Newspaper wrappers
 * Postal cards, different from postcards
 * Prepaid stamped envelopes

See each category for details. 



Blank forms can also be sold by post offices for small amounts when there are numerous rates for different destinations. Stamps are then added as for any letter or card. They are called formula or formular stationery items. 



Some post offices have offered stationery in odd sizes or denominations printed to order.

The only modern worldwide postal stationery catalog was produced by Higgins and Gage in looseleaf format (last edition c.1974, with some price updates as late as in 1986). It has not been updated for decades. Other sources are then stamp catalogs by country, with the occasional specialized stationery catalog available like the Michel catalog for German stationery. The Scott US Specialized Catalog does a creditable job of covering US stationery but the US catalogs produced by the United Postal Stationery Society (UPSS) are preferred by specialists.
