DNNNNNNN |
A code issued by the NHSBSA Dental Practice Division (DPD) for practising GDP's in Wales and England. The codes are available from the NHS Wales Informatics Service or via the Intranet Service HOWIS. |
Structure
Each GDP code begins with the letter D.
The 2nd to 7th characters are the DPD Practitioner Identifier and the eighth character is a check digit. Check digits are obtained using the 137137 algorithm as follows:
First numeric character
+ 3 times second (numeric) character
+ 7 times third character
+ fourth numeric character
+ 3 times fifth character
+ 7 times sixth character
The check digit is then the unit of the result of this calculation. For example, if a DPD is 334512, then the check digit is computed by:
3 + 3*3 + 7*4 + 5 + 3*1 + 7*2 = 62 – the check digit is 2 and the full code would be: D3345122.
