Boeing Numbering System


The system you speak of was first introduced by Boeing in the 1950s with production of the 707. The launch customer of the 707 was Pan Am, and the specific model they had purchased was the 707-120, the initial production version. Thus, the Pan Am aircraft became the 707-121 and Pan Am's numeric designation became 21 (20 represented Boeing itself). The pattern continued with new customers receiving subsequent numbers from 22 to 99. Once 99 had been reached, additional customers received the earlier numbers of 01 to 19. After exhausting the two digit designations, Boeing introduced an alphanumeric system consisting of one letter and one number ranging from A0 to A9, B0 to B9, and so on. This system was also expanded by reversing the order and creating additional codes ranging from 1A to 9A, 1B to 2B, etc. The most recent expansion of the system includes the use of double letters that don't appear to follow any set pattern.

Thus, the following list allows a user to decipher the original customer of any Boeing commercial aircraft built since the early 1950s (complete to the best of our knowledge). For example, a 737-5H4 is a 737-500 bought by Southwest Airlines while a 747-436 is a 747-400 built for British Airways. The codes remain even if the specific airplane has since been sold to another airline, such as a 757-225 originally built for defunct Eastern Airlines but now operated by Airtours. Note that the list also includes buyers of the Boeing Business Jet (BBJ) who are typically corporate operators and not airlines.
