UK Government Data Standards Catalogue (GDSC), Version 2.1, Agreed 01.09.02. GDSC:
This is a type of POSTCODE.
If a PATIENT has no fixed abode this should be recorded with the appropriate code (ZZ99 3VZ).
For overseas visitors the POSTCODES OF USUAL ADDRESS field must show the relevant country pseudo postcode commencing ZZ99 plus space followed by a numeric, then an alpha character, then a Z. For example, ZZ99 6CZ is the pseudo-postcode for India. Pseudo-Country postcodes can be found in the NHS Postcode Directory.
The 8 characters field allows a space to be inserted to differentiate between the inward and outward segments of the code, enabling full use to be made of Royal Mail postcode functionality.
The e-GIF standard POSTCODE should be used for all new and developing systems and for XML messages. For existing CDS EDIFACT messages however, POSTCODE OF USUAL ADDRESS should be used, due to the need to use the exceptional codes listed above.
This data element is also known by these names:
