Directory Management System (formerly OSIS) Listing

The Directory Management System database contains more than 27 million residential and business names, addresses, and telephone numbers supplied by over 80 UK Telecommunication Providers.

The database currently has 35 licensed users of its data and is the source of all telephone number information in the UK.

Entering your information is simple and quick and the numbers normally appear in the online directories within 3 to 6 months.

Entry into the printed phonebooks - which are distributed nationally - is dependent on the timing of the directory printing schedules and can vary between 6 and 12 months.

Entries cost a one off fee of £10 (ex VAT) for a permanent listing. Please provide the information and do double check its accuracy!
