What each type means for the caller
- Toll-free: 13 or 18
- Free to the caller, usually only from inside the country; the business that owns the number pays for the call. 5 digits after +677.
- VoIP: 51 or 52
- Numbers issued for internet telephony services rather than a fixed line or a mobile network. 5 digits after +677.
Writing and dialling a Solomon Islands toll-free number
Solomon Islands has no trunk prefix, so the number is the same at home and abroad; in E.164 put +677 in front: 18123 becomes +67718123. Many freephone numbers still only accept calls from inside the Solomon Islands, 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 Solomon Islands phone number format page covers mobiles and landlines.

- 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 Solomon Islands. 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
