Four-digit phone numbers were primarily used in the United States before the widespread adoption of area codes and seven-digit dialing. This system was prevalent from the early 20th century until the late 1950s, when the North American Numbering Plan was introduced, requiring the use of three-digit area codes and seven-digit local numbers. The transition to seven-digit dialing became standard as more telephone lines were added and the need for more numbers grew.

For a four-digit ID code, you would have 10x10x10x10, so 10000 different codes. With a five-digit and one letter ID code, you have 10x10x10x10x10x26 or 2,600,000 different codes. So there are 2,600,000-10,000 more, or 2,590,000 more codes.
