All registered property agents have a unique CEA registration number e.g. R123456A. This must be displayed with their names on their estate agent cards that must be worn when they meet clients, and shown on advertisements that they put out.
When you have an agent’s CEA registration number, name, or mobile number, you can verify his details via the Public Register on the CEA website or CEA@SG mobile app (available for download on the Apple App Store and Google Play Store).
