We currently do not have postal codes for Singapore available in Tableau directly.
We currently support postal codes in the following areas:
- New Zealand
When we add Singapore postal codes it would be helpful if we could validate them against your data. If you could attach a workbook with them listed here or even an Excel workbook with them listed, we would appreciate it.
Geopostcodes.com offers the database cost $200. Tableau should be affordable to purchase it and upload it.
This database should be trust worthy, just need some users to try them out.
There are sample data available from the website.
The cost may be higher depends how geopostcodes classified the application in Tableau.
Details should be found in the website.
