Singapore Citizens/Permanent Residents residing in Singapore
Residential address
You need to update the change of residential address in your Identity Card (NRIC) online using the Immigration and Checkpoints Authority (ICA)’s Change of Address e-Service. If you are unable to update your address online, you may appoint proxies who are Singpass holders to submit an application on your behalf or visit ICA for assistance. Find out more about the online change of residential address.
As IRAS is one of the participating government agencies and statutory boards of the One-Stop Change of Address Reporting Service (OSCARS) system, we will be informed of your new address through OSCARS on the next working day automatically.
Mailing address (if different from your residential address)
If you wish to receive correspondence from IRAS at an address other than your residential address in your Identity Card (NRIC), please email us your mailing address.
