MPS Documentation - the Person_ID handbook

Documenting how the Person_ID is generated via the Master Person Service (MPS), to make the current process of linking data in the NHS more transparent and easy to understand.

The Person_ID is a unique patient identifier used by NHS England with the objective of standardising the approach to patient-level data linkage across different data sets. The Data Linkage team has produced a detailed documentation of the data linkage algorithm used to create the Person_ID, namely the Master Person Service (MPS). The figure below is an overview of the process. The full documentation is available in this NHS England site.
