Telephone Exchange Names

This article is still being worked on, but I wanted to share it before it was completed. If you want to be notified when it is updated leave a comment below.

When I was a child I lived in San Bernardino, California from 1966 to 1969. I can still remember my home telephone number: TUrner 5-2176, sometimes abbreviated as TU 5-2176. My grandparents’ telephone number was TU 3-5155.

If I wanted to call my grandparents, since we both lived in the TUrner area, I only had to dial 3-5155. But if I called someone outside the TUrner area, I had to include the two letters, for example, to call someone at UNion 4-7721 I had to dial 864-7721.

So what or who was TUrner?

The Central Office

Prior to 1955, many people had been using exchange names that were not included in the official list and they were not required to change them. For example, I remember advertisements on television urging me to call RIchmond 9-5171 to go see Championship Wrestling at the Olympic Auditorium in Los Angeles. The official exchange names were PIlgrim, PIoneer, RIverside, RIverview, SHadyside, and SHerwood.

The National Numbering Plan

The National Number consists of ten digits as follows.

Table 1. Composition of the National Number.
Listed Directory Number
Area Code Office Code Station Number
X1 X2 X3 L L N N N N N

Where
L = Any letter from Table 2 below.
N = Any numeral from 0 to 9.
X1 = Any numeral from 2 to 9.
X2 = 0 (zero) or 1.
X3 = Any numeral from 0 to 9 when X2 = 0. Any numeral from 0 to 9 except 1 when X2 = 1.

Table 2. Dial Pulses Corresponding to the Letters of the Office Code Portion of the National Number.
Letters No. of Dial Pulses
A   B   C 2
D   E   F 3
G   H   I 4
J   K   L 5
M   N   O 6

The information in Tables 1 and 2 was taken from “Section II Chart 1: The National Numbering Plan” in Notes on Nationwide Dialing (1955).
