SLT RAINBOW PAGES is Sri Lanka’s only telephone directory published by SLT Digital Services (Pvt) Ltd [formerly SLT Publications (Pvt) Ltd], a fully-owned subsidiary of Sri Lanka Telecom PLC (SLT) - the pioneer and foremost telecommunication solutions provider to the nation.
The telephone directory is published and distributed primarily to all SLT subscribers including government organizations, business organizations, religious institutions, residential customers etc. The word ‘directory’ has been very synonymous with Sri Lanka Telecom since it is the only publisher of telephone directories in Sri Lanka since 1939. Formerly, publication of telephone directories was carried out by a separate department of SLT. However, from 1983 to 2000, publication of telephone directories was outsourced to a third party, but in the year 2001, it was brought back to SLT. Then the telephone directory was branded as SLT RAINBOW PAGES and the first SLT RAINBOW PAGES Directory was published in the year 2002. In the year 2008, publication of the telephone directory was brought under the purview of a separate organization viz. SLT Publications (Pvt) Ltd, merely established as a wholly-owned subsidiary of SLT to undertake this task for providing a much better service.
