01489


01489 is the national dialling code for Hamble Valley in the United Kingdom. Before PhONEday the area code was 0489, with the mnemonic HV 9 where HV are taken from the letters H and V in Hamble Valley – an unofficially recognised geographic area surrounding the River Hamble in Hampshire.[1] The dialling code is rarely ever referred to as Hamble Valley (and its name appears to be generally unfamiliar to the residents of the area that it serves), but is instead referred to as Botley, or less frequently (except by residents of the immediate area) as Bishop's Waltham or Locks Heath. In common with all other British area codes the initial '0' is a trunk prefix that is not required when dialling from abroad.

History

Hamble Valley was included in the Fareham charge group along with the 0329 STD code which served Fareham town centre, Stubbington, Titchfield, and Wickham. The Fareham charge group was unusual because it was a dependent charge group of two Group switching centres (GSC). Hamble Valley telephone exchanges with an 0489 STD code were parented onto the Southampton GSC, and Fareham telephone exchanges with an 0329 STD code were parented onto the Portsmouth GSC.

The routing digits for 0489 in distant STD exchanges were the same as those for Southampton (0703) followed by 92. The routing digits for 0329 in distant STD exchanges were the same as those for Portsmouth (0705) followed by 92.[2]

Hamble Valley telephone exchanges were not arranged in a linked numbering scheme, so 0489 was suffixed with a digit identifying the particular exchange.[3] The same suffix digit was also used in local dialling codes from Southampton.

Bishop's Waltham04893
Locks Heath04895

Hamble valley telephone exchanges gradually became part of a linked numbering scheme during the 1980s with the STD code 0489, and the original 3, 4, and 5 figure numbers became 6 figure, when Strowger telephone exchanges were replaced with digital telephone exchanges.

Calls from the Fareham charge group were charged at local rate to telephone exchanges in the following STD codes:[4]

STD code Location
0329Fareham
0421Southampton ring code
0489Hamble Valley
0701Portsmouth ring code
0703Southampton
0705Portsmouth
0730Petersfield

0983Isle of Wight

Telephone exchanges in 0421 and 0701 were gradually transferred into 0703 and 0705 respectively, and added to their linked numbering schemes.

Former local dialling codes

From Southampton:

Exchange name Dialling code
Botley922
Bishop's Waltham923
Locks Heath925
Durley926
Droxford927

924 was the local dialling code for Fareham (0329) from Southampton, which resulted in 04894 becoming unusable as an STD code.

From Winchester:[5]

Exchange name Dialling code
Botley93922
Bishop's Waltham928
Locks Heath93925
Durley93926
Droxford93927

Calls to Hamble Valley exchanges were routed via Southampton except to Bishop's Waltham which had a direct connection to Winchester. The unpublished dialling code 93923 would also have worked for Bishop's Waltham with the call routed via Southampton. 93 was the local dialling code for Southampton from Winchester.

From Ryde, Isle of Wight:[6][7]

Exchange name Dialling code 1968 Dialling code 1979
Botley9392204892
Bishop's Waltham9392304893
Locks Heath9392504895
Durley9392604896
Droxford9392704897

Calls to Hamble Valley exchanges were routed via Southampton. 93 was the local dialling code for Southampton from Ryde. By 1979 the local dialling codes had been withdrawn and the full STD codes for the exchanges were required.

From Petersfield:[8]

Exchange name Dialling code
Botley04892
Bishop's Waltham04893
Locks Heath04895
Durley04896
Droxford04897

Full STD codes were required in 1971 which implied that no direct connections existed between Petersfield and the Hamble Valley exchanges.
