The use of taxis for mail transfer and especially for letters existed long before 1948, though it was generally not very popular because of its relatively high cost, its limited service span, and the fact that it was illegal (during certain periods). However, especially during 1948, the year of Israel's fight for independence, this type of unpopular and unusual mail transport was very important. In view of the steadily-increasing insecurity of the postal services, commencing as early as the beginning of 1948, senders of mail increasingly availed themselves of other means of transport for mail. Therefore, the importance of mail transport by buses and taxis increased, as well as the volume of mail carried in this way. Above all, it was the omnibus company Egged, a Jewish co-operative, which linked virtually all the better-known and larger places of the country by a network of regular routes. Also in existence then was another motorized-transport system, considered unique to Israel, the ”sherut” taxis, which travel in a planned manner on the main routes between Tel Aviv and Jerusalem, Tel Aviv and Haifa, and Haifa and Jerusalem, and the roads leading to Tiberias in the north. A number of taxi companies seized the opportunity to increase profits by adding the transmission of letters and parcels to their passenger services. Thus, the increasing volume of both incoming and outgoing taxi mai in the first few months of 1948 was considerable, and this increase was certainly a manifestation of the unreliability of the British Mandate postal services. The taxi mail of the Transition Period may therefore be logically considered to be part of the postal history of the Transition Period.
