Toll-free and premium numbers in Singapore
Toll-free numbers in Singapore start with 1800 or 800 after the country code +65 and have 10 or 11 digits after the country code. Premium-rate numbers start with 1900. Example: 1800 123 4567, or +6518001234567 in E.164.

What each type means for the caller
- Toll-free: 1800 or 800
- Free to the caller, usually only from inside the country; the business that owns the number pays for the call. 10 or 11 digits after +65.
- Premium rate: 1900
- Charged above a normal call at a rate set by the service, with part of the charge going to the service provider. 11 digits after +65.
- Universal access (UAN): 7000
- One national number for a business with several sites, routed to the nearest or chosen office. 11 digits after +65.
- VoIP: 31, 32 or 666
- Numbers issued for internet telephony services rather than a fixed line or a mobile network. 8 digits after +65.
Writing and dialling a Singapore toll-free number
Singapore has no trunk prefix, so the number is the same at home and abroad; in E.164 put +65 in front: 1800 123 4567 becomes +6518001234567. Many freephone numbers still only accept calls from inside Singapore, and a call from abroad that does connect is usually charged.
Toll-free and premium numbers in a phone list
In a lead or customer list, a toll-free number usually reaches a company line rather than a person, and a premium-rate number costs you money to call. The free toll-free number checker flags them in a pasted list or CSV, and the Singapore phone number format page covers mobiles and landlines.

Common questions
- What is the toll-free prefix in Singapore?
- Singapore toll-free numbers start with 1800 or 800 after +65. Every valid toll-free number starts that way, though not every number with those digits is in service.
- How many digits is a Singapore toll-free number?
- 10 or 11 digits after the country code +65.
- Can I call a Singapore toll-free number from abroad?
- Sometimes. Dial +65 and the number. Many freephone numbers only take calls from inside Singapore, and where they do connect from abroad the call is usually charged.
- How do I spot a premium-rate number in Singapore?
- By its first digits: 1900. The prefix tells you the range is charged; the actual price is set per service.

- Ranges, lengths and examples: Google libphonenumber numbering-plan data (libphonenumber-js 1.13.15), the data our validator uses.
- Official plan: ITU-T E.164 national numbering plan for Singapore. The regulator’s filing is the authority when the two disagree.
The numbering plan only knows what a range was issued for.
In the US and Canada mobiles and landlines share the same prefixes, and anywhere a number can be ported or reassigned the range stops telling the whole story. A live carrier lookup asks the network data instead, which is what Pro + Phone ($49.99/mo) adds.
- 5,000 live carrier lookups a month: real line type, including US numbers
