Direct Dialling In (DDI) allows end-customers to control their own numbering and receipt of calls. A group of Digital channels can have up to 5 DDI number ranges allocated on the same installation. Each DDI number range would provide a continuous sequence of a minimum 10 DDI numbers.
DDI numbers are available for Digital System only.
DDI is not available at all exchanges.
DDI numbers are available to order in blocks of 10 numbers.

Notes:
1) Planning Charges apply to changes to numbers at an installation, per DDI Installation. This charge also applies to changes to any single number DDIs. Where a Customer requests an addition to an existing DDI installation, this charge applies plus any additional number charges which apply. This charge does not apply where the whole DDI range is being ceased or where 10 number blocks are being ceased from the end of the range. However, this charge does apply where number blocks are ceased from the beginning or middle of a DDI range.
2) The annual price associated with this product would normally need to be divisible by 12 to be billable. In line with other products Openreach will now flex the monthly charges by a penny up or down, so that over the course of the year the total price charged is no more than the annual price. The flexing of the monthly charges is shown below.
