If you find a letter addressed to a previous owner after moving into an HDB flat, keep it sealed and return it through the postal service. For an ordinary envelope with your correct unit number but a former resident’s name, mark the outside “Return to sender. Addressee no longer lives here” and look for the returned-mail slot by your block’s letterboxes. If you cannot find one, check with SingPost for the right way to hand it back.
A letter can keep coming because one sender still has an old address on file. Repeated mail from a single sender, a mismatch in your own registered address and suspected use of your address in an active transaction each have a different first point of contact.
- Check the recipient and unit number before returning the envelope.
- Keep the contents private and use an official contact channel for repeat senders.
- If your own registered address looks wrong, contact ICA promptly.
- Keep your move-in documents handy if you need to verify when you took over the flat.

Check the envelope before choosing a route
Check the printed name, unit and postal code. If the address belongs to another flat, tell the postal service the item was delivered to the wrong unit. If the unit is yours and you know the addressee moved, use that description. For an unfamiliar name, “Addressee unknown at this address” describes what you know.
| What you find | First step |
|---|---|
| One sealed envelope for a former resident | Mark it for return and use the returned-mail route |
| An envelope for a different unit | Flag the delivery error to the postal service |
| Repeated letters from an identifiable institution | Contact the sender through its published number or website |
| An incorrect address on your own ICA record | Check ICA’s reporting guidance and contact ICA promptly |
| Signs that someone is actively using the address | Note the facts and contact the relevant institution |
If the item is a tracked parcel or requires a signature, ask the courier how to handle it. You can tell the courier at the door that the recipient has moved and let the courier follow its return procedure.

Contact the sender when the same mail keeps coming
Use the organisation’s official website to find its customer service number or form. Explain that you now occupy the unit and have received repeated mail for someone who moved. Start with details visible on the outside and ask how the organisation records returned correspondence. Share only what the official channel needs.
You can say, “I moved into this unit in October. Letters from your organisation keep arriving for a former occupant. I’ve returned them unopened. Which team should I contact about the mailing address?” If you still have a contact for the seller or agent, you can ask them to pass on a reminder to update mailing details.

Separate a sender’s record from ICA registration
A bank, insurer or school can hold its own mailing details. An envelope tells you which address was printed for that delivery. To check your own registered address or raise a concern about a registration issue, use ICA’s contact channels. ICA says identity-card holders must report a change of residence within 28 days of moving. The person who moved can use ICA’s change-of-address service.
If someone says they are collecting money or delivering a formal notice for a former resident, note the date, organisation and what was said. Verify the organisation independently before sharing household details or purchase papers. Tell the verified organisation when you took over the unit and ask how to record that the person moved. Where the facts suggest fraud or intimidation, use the relevant authority’s official reporting channel.

Frequently asked questions
What if my child brings the letter upstairs?
Ask them to bring unfamiliar envelopes to an adult and leave them sealed. An adult can check the name and address and decide how to return the item.
Should I keep a record of every letter?
For occasional mail, returning it may be enough. If a pattern develops, a private note of dates, sender names and contacts gives you something to refer to. Keep names and envelope photos out of public group chats.
What should I check for my own household?
List the organisations that send you important correspondence. Start with ICA’s address service and confirm separately how your school, employer, bank and insurer handle address updates.
