About Standard Names and Codes (SNAC)
SNAC was a database that provided tables of ONS standard names and codes for a range of UK geographies.
It enabled users to relate areas to their respective geographic hierarchies.
The database offered alternative administrative area names and codes as used by Communities and Local Government (DCLG) and the Department of Health (DH).
SNAC provided information on a range of geographies including Output Areas/Super Output Areas, and various administrative, electoral and health areas.
A full listing of geographies covered is provided in the User Guide. The 2010 version of SNAC, which was the last in its current format, contains the old style hierarchical coding only, and not the new 9 character coding.
From 2011 onwards the new GSS Coding and Naming policy for some statistical geographies will be implemented.
From this date, where new codes have been allocated they should be used in all exchanges of statistics and published outputs that normally include codes.
From 2011, SNAC will only contain frozen geography information.
The Code History Database (CHD) will replace SNAC for the current geography information.
The Code History Database (CHD) provides multiple functionality including details of all codes, relationships, hierarchies and archived data.
Initially, the CHD will be used in parallel with the Standard Names and Codes (SNAC) database, but ultimately it will replace it.
SNAC is an MS Access 2002 database (MS Access 97 and MS Access 2000 formats are available on request - please contact us).
It is also available in MS Excel, but with reduced content and functionality.
The SNAC User Guide found in the Downloads section provides further details on the product.
Availability and cost
The 2010 edition of SNAC can be downloaded free of charge from the Downloads section.
