Changing your address in Singapore
One government update fans out — everything else is on you.
Government systems mostly sync from one ICA update. Banks, insurers, telcos and subscriptions do not — each keeps your old address until you change it. Mail that still arrives at the old unit is your remaining to-do list.
1.Government first (one update, wide effect)
Do the ICA update before anything else — many agencies follow automatically.
- ICA eCOA: report the new address
Log in with Singpass at go.gov.sg/ic-address. A 6-digit PIN is mailed to your NEW address; enter it to verify, then paste the address sticker on your IC. Free of charge.
- Let OSCARS fan out, then verify MyInfo
Participating agencies (IRAS, HDB, CPF and others) update within about one working day. A day later, open Singpass → MyInfo and confirm the new address shows.
- Check mailing address separately (IRAS and others)
OSCARS updates your residential address. A different mailing address does not move with it — check myTax Portal → Update Contact & Notice Preferences.
Residential and mailing addresses are separate fields in several agencies.
- Special cases: overseas move, work passes
Moving overseas: register a Local Contact Address with ELD to stay on the electoral roll. Work pass / LTVP holders update via MOM or ICA FDW eService instead.
2.Private sector (no auto-sync)
None of these listen to OSCARS. Update each one; many apps can pull the new address from MyInfo once you tap update.
- Banks, cards and insurers
Statements, replacement cards and policy letters go to the registered address. Most SG bank apps let you sync from MyInfo after your ICA update — do ICA first, then this is two taps.
- Utilities, telco, town council / MCST
SP or Open Electricity account for the new place, close or transfer the old one. Update billing addresses at your telco and ISP. Inform town council or condo management.
- Employer, school, clinics, memberships
HR records, school contact records, family clinic, dental, gym, season parking.
- Delivery addresses: Shopee, Lazada, Amazon, food apps
Change the default address and delete the old one, or your next parcel goes to a stranger. Check saved addresses in ride apps too.
3.Safety net
You will miss some. Make the misses visible instead of silent.
- SingPost mail redirection for 3–6 months
Every redirected letter identifies an organisation you forgot. Update it, then wait for the redirect to go quiet.
- Ask the new occupant (if you can)
Mail still arriving for you at the old unit after 2–3 months is the definitive list of what you missed.
