Mae Ofcom yn parhau i dderbyn ceisiadau am Rifau Daearyddol i'w defnyddio at ddibenion drama. Mewn ymateb i hyn, mae Ofcom wedi pennu amyrwiaeth o Rifau Ffôn Daearyddol at ddibenion rhaglenni drama (rhifau 1000 o fewn pob Ardal Cod Daearyddol).
Mae'r cynnwys isod ar gael yn Saesneg yn unig.
1. Ofcom has not selected a telephone number range for all geographic area codes, as it has to ensure that there is sufficient numbering capacity available to meet future requirements for 'real' telephony purposes. Telephone numbers recommended for drama purposes cannot be allocated to communications providers for their customers because of the potential influx of calls that customers might receive should their telephone numbers be shown in a drama.
2. Ofcom suggests using numbers in the 01632 range (no area code) for any geographic area code not listed.
3. The use of any telephone number in the ranges below does not imply that the number has been allocated. The numbers will not be allocated to communications providers in the foreseeable future.
