Phone Number Checker Singapore: Mobile, Landline, VoIP or Overseas?

Free · No sign-up · Updated October 2026
Free check of any Singapore phone number's format and type (mobile, fixed line, VoIP, 1800, overseas) from IMDA's numbering plan, plus ScamShield advice.

Checked in your browser. Nothing is sent, looked up or saved.

This checker reads the number's format only. It cannot tell you who called: Singapore has no public reverse phone directory, and mobile numbers can be moved between telcos, so the digits do not reveal the network or the owner.

Got a suspicious call?

Advice from the Singapore Police Force and the National Crime Prevention Council.

  • Hang up and check. Government officials will never ask you to transfer money or give bank log-in details over a phone call. Call the official number of the agency or bank yourself, from its website or the back of your card.
  • Unsure? Call 1799. The ScamShield Helpline runs 24/7 and can tell you whether something is a known scam (+65 6869 1799 from overseas).
  • Watch for a + you did not expect. Only international calls show a + in front. Don't pick up +65 calls unless you are expecting one from overseas; your telco can also block international calls if you opt in.

How to report it

  1. Report the number in the ScamShield app, which also blocks calls from numbers linked to scams.
  2. If you have lost money or shared bank details, call your bank's 24-hour hotline straight away to freeze your accounts.
  3. Make a police report online at police.gov.sg (e-services). Call 999 only if you need urgent police help.

How this works

Singapore numbers have no area codes. Under IMDA's National Numbering Plan (Issue 2, February 2026) a phone number is 8 digits and its first digit sets the type: 8 and 9 are mobile numbers, 6 is fixed line (and some internet phone services), and 3 is IP telephony (VoIP) and data-only services. Numbers starting with 2, 4 or 5 are reserved for future use, so no Singapore line has one. The country code is +65.

Toll-free numbers are 1800 followed by 7 digits and premium-rate numbers are 1900 followed by 7 digits. Codes starting with 1 that are 4 or 5 digits long are special services (such as 1799, the ScamShield Helpline, and 1777, the SCDF non-emergency ambulance), 5-digit codes starting with 7 are SMS short codes, and 995 (SCDF) and 999 (police) are emergency numbers.

Since April 2020, Singapore telcos show a + in front of the caller ID only for international incoming calls. A call that shows +65 therefore came through an overseas network: either a Singapore phone roaming abroad, or a scammer faking a local number. The checker runs entirely in your browser and only reads the format. It cannot identify the caller or the telco, because Singapore has no public reverse directory and mobile numbers can be ported between operators.

FAQs

How can I find out who called me in Singapore?

You can't from the number alone: Singapore has no public reverse phone directory, and this tool only checks the number's type and format. If the call was suspicious, call the ScamShield Helpline on 1799 (24/7) to check, and report the number in the ScamShield app.

Is a number starting with 3 a scam?

Not necessarily. Singapore numbers starting with 3 are 8-digit VoIP (IP telephony) numbers under IMDA's numbering plan, used by internet calling services and some businesses. They are not tied to a SIM card, so treat unexpected calls from them with care.

Why does a call show +65 in front of the number?

Because it came in through an overseas network. Since April 2020 only international incoming calls display a +, so a +65 caller is either a Singapore phone roaming abroad or a spoofed number. The police and IMDA advise not picking up + or +65 calls you are not expecting.

How many digits is a Singapore phone number?

8 digits: mobile numbers start with 8 or 9, fixed lines with 6 and VoIP numbers with 3. Toll-free 1800 and premium 1900 numbers have 11 digits, and short codes such as 995, 999 and 1799 have 3 to 5.

Where do I report a scam call in Singapore?

Report the number in the ScamShield app, call your bank's hotline at once if you have lost money, and make a police report online at police.gov.sg. The ScamShield Helpline (1799) can tell you if something is a scam but cannot take police reports; call 999 for urgent police help.
