Donor communications provider meaning

A donor communications provider is the customer’s existing telecoms provider from which a telephone number is transferred (ported) to a new, recipient provider during number portability. The role arises where a number is being, or has been, ported for fixed or mobile services. In the UK, the term Donor Provider is used in Ofcom’s General Conditions of Entitlement governing switching and number portability. In Ireland, ComReg regulation and industry codes use the equivalent terms donor operator or donor service provider. Usage and obligations are broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland. Key legal features and practical significance: - Facilitates number portability by validating port requests and releasing numbers to the recipient provider without undue delay. - Must not obstruct or unduly delay porting; any charges must be cost-based and compliant with regulatory rules. - Coordinates technical and administrative processes (for example, routing and data exchange) to ensure continuity of service until the port completes. - Has residual duties post‑port, including final billing, ceasing the old service, and updating records (such as caller line identification and routing) to avoid mis‑delivery of calls. Typical contexts include switching agreements, porting disputes, and regulatory compliance under Ofcom and ComReg rules.
