The Telegraph Numbering Plan is the system which allocates telephone and telegraph numbers in Great Nortend which is administered by the General Post Office's Telegraphic Department.

History

As the name suggests, the original Telegraph Numbering Plan was originally devised in the early 20th century after the Great Astyrian War by the General Post Office to provide for a more efficient method of directing telegraph messages for telegrammes. In the 1950s, a major revision was undertaken to unify the expanding telephone network with the telegraph network and to provide for a way of directing the increasing number of voice calls and telegraphs.

Format

Telephone

Normal telephone numbers are eight digits long and comprise a four digit area number and a four digit subscriber number. In order to dial a subscriber number at another exchange, the operator prefix 0 must be dialled first, followed by the area number and then the subscriber number. When dialling a subscriber at the same exchange, no trunk prefix or area number is necessary.

A subscriber number is a four digit number, the first digit whereof may be any number from 1 to 8. Other digits may be any digit from 0 to 9. This provides 8,999 possible combinations per telephone exchange. Telephone exchanges are based in towns and larger villages which usually are also the post town of the region. Most have between 100 and 3,000 subscribers. The Numbering Plan allows for future expansion, by increasing the number of digits in a subscriber number.

The four digit area number is displayed in letters and is is split into two portions, the first two letters being the county code and the last two letters being the specific exchange code. The area code is linked with the post office number insofar as the first two digits of a post office number is usually the exchange code.

For example, the postal region of Asham has the postcode Eamshire 27. Thus, Asham telephone exchange which services the postal region of Asham has the area number EAAS, EA denoting Eamshire and AS denoting Asham postal region. This is dialled on the telephone 3227.

Subscriber numbers are allocated according to which sub-p Non-geographic numbers are available for special services. They are dialled beginning with the operator prefix 0 followed by a two digit code. These codes are :

• 10 XXX XXX: Local rate numbers
• 11 XXX XXX: Technical numbers
• 30 XXX XXX: Free call numbers
• 48 XXX XXX: Government numbers
• 50 XXX XXX: Concession rate numbers
• 60 XXX XXX: National rate numbers
• 81 XXX XXX: Premium rate level 1 numbers
• 82 XXX XXX: Premium rate level 2 numbers
• 83 XXX XXX: Premium rate level 3 numbers
• 88 XXX XXX: Special numbers

Subscriber numbers for non-geographic numbers may be as short as three numbers. For example, dialling 0 10 520 connects to Langton's Bank.

Simply dialling 0 will connect the caller to the operator, who can conect the call. 0 00, or “triple-nought” is the emergency number which will connect the caller to a specialised emergency call operator who can quickly arrange the appropriate emergency response. It is possible to call an operator at another exchange by dialling the area number and then the 'subscriber' number 0.

Telegraph

Telegraph numbers, which are used to direct telegraphs and send telegrammes, are also incorporated with the Numbering Plan. Telegraph numbers begin with the telegraphic prefix 9.

Telegrammes which are sent through the GPO network are sent with a geographic number corresponding to the appropriate destination post office, or appropriate intermediate office. They are six digits long, comprising of the same four digit area number as with telephone numbers, and a two to four digit subscriber number corresponding with the post office.

Commercial telegraph subscribers have non-geographic numbers with the two digit code 84. For example, Langton's Bank's telegraph number is 9 84 520.

International access

The GPO does not currently allow most subscribers to directly dial international numbers. Rather, subscribers must dial 0 for the operator, and say the international telephone number. Some exchanges offer international subscriber dialling to select subscribers. In these cases, the international dialling prefix is 0 13.
