Duplicate NHS Numbers
A duplicate is where 2 or more NHS Numbers exist for one NHS patient. We investigate and confirm whether the NHS Numbers relate to the same person.
When duplicate NHS Numbers are confirmed the records are merged, leaving the patient with a single unique NHS Number.
The outcome of the investigation is reported to the primary healthcare provider for the patient concerned.
Read about a duplicate registration case study.
Advice for members of the public
If you are a member of the public who has two or more NHS numbers you will need to contact your GP surgery. Alternatively, please contact your Clinical Commissioning Group (CCG) if you are not registered with a GP.
