What Is the Country Code for the Solomon Islands?
The country code for the Solomon Islands is 677. It is assigned by the International Telecommunication Union (ITU) and is placed after your exit code whenever you call the country from abroad. It identifies the whole nation, from Honiara on Guadalcanal to Gizo in the Western Province.
Many people search for "677 area code", and that is understandable because the US and Canada use three-digit area codes that look similar. The difference matters. In the US, an area code narrows a call to a region within one country. In the Solomon Islands, 677 is the code for the entire country, and the numbers that follow are the national numbers. Local numbers are not preceded by a separate dialing area code, so there is nothing to add between 677 and the number you were given.
Some older sources show notations such as a two-digit prefix before the rest of a landline number. Those leading digits are simply the first digits of a five-digit number. They are part of the number and should be dialed exactly as written.
How to Call the Solomon Islands from Australia
The dialing sequence is the same from every Australian landline and mobile. You enter the exit code for international calls, the country code, and then the national number. Telstra's published guidance gives the Australian format as 0011 plus the country code plus the local number, and the same pattern applies on other Australian carriers.
- Step 1: Dial the exit code. Enter 0011 on a landline. On a mobile you can instead press and hold the 0 key to type the + sign, which tells the network to insert the correct exit code for you. Saved contacts that begin with + work from any country, which is useful if you travel.
- Step 2: Enter 677. This is the Solomon Islands country code. Type it straight after the exit code with no pause.
- Step 3: Enter the national number. For a landline, add the five digits. For a mobile, add all seven digits. Drop any leading zero if the number was written with one, because the Solomon Islands does not use a trunk zero in international format.
- Step 4: Press call and wait. International calls can take several seconds to connect. If you hear a fast busy tone, recheck the digit count before redialing.
Here is how the same number looks in the formats you will meet:
| Where you dial from | Landline example | Mobile example |
|---|---|---|
| Australian landline | 0011 677 2xxxx | 0011 677 7xxxxxx |
| Australian mobile (plus sign) | +677 2xxxx | +677 7xxxxxx |
| Written internationally (E.164) | +6772xxxx | +6777xxxxxx |
| Dialed from inside the Solomon Islands | 2xxxx | 7xxxxxx |
Some Australian providers also offer alternative access codes with different rates, and a few prepaid services use their own access numbers. Check your provider's international rates page, because the cost of the same call can vary a lot depending on the prefix or plan.
Solomon Islands Phone Number Formats: Landline vs Mobile
The Solomon Islands uses two number lengths, and the length tells you the type. According to the published numbering summary, fixed-line numbers have five digits and mobile numbers have seven digits. Knowing this lets you spot a mistyped number before you dial.
Landline numbers Landlines are five digits long, and the leading digits are assigned in blocks by town or island. These are not area codes you dial separately. They are the front of a number that you dial whole.
Mobile numbers Mobiles are seven digits long and the leading digits depend on the network. If you are given a mobile number with only five or six digits, something is missing, and you should ask the owner to resend it.
Toll-free and free-call blocks Five-digit ranges starting 18 are reserved for toll-free services and ranges starting 13 for free-call services. A toll-free number inside the Solomon Islands is generally not reachable for free from overseas, so expect to pay the standard international rate if you dial one from Australia.
Texting SMS to a Solomon Islands mobile uses the same +677 followed by the seven digits. Delivery and pricing depend on your provider, and some messaging apps that use data avoid per-text charges entirely.
| Number type | Digits after 677 | Typical start | Example pattern |
|---|---|---|---|
| Landline | 5 | 14 to 29, 40, 50, 60 to 62 | 677 2xxxx |
| Mobile | 7 | Mobile blocks vary by network | 677 7xxxxxx |
| Toll-free | 5 | 18 | 677 18xxx |
| Free-call service | 5 | 13 | 677 13xxx |
Time Difference Between Australia and the Solomon Islands
The Solomon Islands runs on UTC+11 and does not use daylight saving time, so Honiara's clock never changes. Australia has several zones and some states change their clocks, so the gap varies through the year.
| Australian city | Standard time gap | During daylight saving (about October to April) |
|---|---|---|
| Sydney, Melbourne, Canberra, Hobart | Honiara is 1 hour ahead | Same time |
| Brisbane (no daylight saving) | Honiara is 1 hour ahead | Honiara is 1 hour ahead |
| Adelaide | Honiara is 1.5 hours ahead | Honiara is 0.5 hours ahead |
| Darwin (no daylight saving) | Honiara is 1.5 hours ahead | Honiara is 1.5 hours ahead |
| Perth (no daylight saving) | Honiara is 3 hours ahead | Honiara is 3 hours ahead |
For a family call, late afternoon and early evening in Honiara usually suit people after work or school. For a business call, weekday mornings, roughly 9 a.m. to noon in Honiara, avoid lunch and the end of the day. Always confirm the other side's local time before ringing, particularly when you are calling from Perth, where the gap is largest.
Ways to Call the Solomon Islands from Australia
Dialing is only half of the decision. The method you pick changes the price, call quality and whether the other person needs anything installed. The table compares the common options.
| Method | Best for | What to know |
|---|---|---|
| Standard carrier call (0011 or +) | One-off calls | No setup, but per-minute rates to the Pacific can be high. Check your plan |
| Carrier international add-on | Regular family calls | Bundles can lower the rate; confirm Pacific countries are included |
| Prepaid calling app or card | Occasional calls | Pay for what you use. Compare rates for mobile and landline separately |
| Messaging apps (data) | Chats and video | Free apart from data, but both people need the app and a stable connection |
| VoIP or virtual business number | Businesses and frequent callers | Calls over the internet; rates are often lower, and teams can share numbers |
Standard carrier calls: This is the simplest route because it uses your normal phone, and it works with any Solomon Islands landline or mobile. The downside is cost, since Pacific destinations are often among the more expensive in a provider's rate table. Look up the per-minute rate before a long call.
Messaging and video apps WhatsApp, Facebook Messenger and similar apps work well if both people have a data connection. In practice, mobile data in parts of the Solomon Islands can be slow or patchy outside the main centers, so voice calls may sound better than video.
Prepaid calling apps and VoIP These route your call over the internet and hand it to the local network at the far end, which is why they are often cheaper than carrier rates. If you call the Solomon Islands often, for a business or a relative, a VoIP service is usually the more economical choice. The cost logic is the same one people use when they make international calls from the USA: compare the carrier rate with prepaid and internet-based options before a long call.
Using a VoIP Service or Virtual Number for the Solomon Islands
A VoIP service places calls over the internet instead of a copper line or mobile network. For anyone with a regular need to reach the Solomon Islands, such as a business with suppliers there, an NGO coordinating projects, or a family with relatives, it offers lower rates and more control.
Lower per-minute cost Because the call travels over the internet for most of the journey, rates to the final destination are usually lower than a standard carrier's international price. Compare rates for mobiles and landlines separately, since the same provider may charge differently for each.
Calling from a computer or phone app A web phone or mobile app lets you dial from a browser or smartphone without changing your SIM. This helps when you are traveling or working from a laptop, and it keeps business calls off your personal number.
Caller ID that people recognize People in the Solomon Islands may ignore calls from an unknown foreign number. With the right setup, a business can show a consistent number so contacts know who is calling. Providers handle custom caller ID differently, and rules differ by country, so check what your provider supports.
A virtual number for the other side A virtual phone number lets people reach you on a local-looking number and forwards the call over the internet. Availability of Solomon Islands (+677) numbers depends on the provider, and number activation varies by country, so confirm that before promising customers a local line. Calilio, for one, includes a free local number in the US, Canada or UK with every plan, and the virtual phone number page lists current options.
Call quality over the internet Voice over IP depends on a stable connection at both ends. Aim for low latency and little packet loss, and run a VoIP quality test before an important call. Measures such as latency, jitter and packet loss decide VoIP call quality.
Calling the Solomon Islands for Business
Companies in Australia often call the Solomon Islands for tourism, mining and forestry, fisheries, aid projects and supply chains, and a missed or poor-quality call can cost a deal. A few practical habits help.
Plan around time zones Hold calls in the overlap of both working days. Because the gap is at most three hours from Perth, there is almost always a convenient window, but public holidays differ, so check both calendars.
Record and log calls where permitted Call notes, tags and recordings help a team follow up after a conversation with a supplier. Rules on recording vary by place, so tell the other party and check the laws that apply to you. This is general information and not legal advice.
Share one number across the team A cloud phone system lets several people use the same business number and route calls to whoever is available, so a contact in Honiara reaches a person instead of voicemail. Features such as call forwarding and business hours keep calls moving when someone is away.
Keep a backup channel Because internet access can vary at the far end, confirm an alternative such as a mobile number or messaging app so a dropped call does not end the conversation.
Common Mistakes When Calling the Solomon Islands
Most failed calls come down to a handful of avoidable errors.
Adding a zero Do not insert a 0 after 677. The Solomon Islands does not use one, and it will make the number too long.
Wrong digit count A landline has five digits and a mobile has seven. A number with a different length is incomplete or mistyped.
Calling at the wrong hour Honiara is up to three hours ahead of Australia. A midday call from Perth is already mid-afternoon there.
Assuming the call is free or cheap Premium or toll-free numbers inside the Solomon Islands do not guarantee a free call from abroad. Check the rate first.
Confusing 677 with a US area code A search for "677 area code" can return results about other countries. In the Solomon Islands, 677 is the country code only.

Ready to Get Started?
Calling the Solomon Islands from Australia comes down to a short sequence: exit code 0011 or +, country code 677, then a five-digit landline or seven-digit mobile number, with no leading zero. The time difference is small, and the real decision is which method gives the best price and call quality for how often you call.
For occasional calls, a standard carrier call or a messaging app is enough. For regular family or business calling, a VoIP service can lower the cost and add features. Calilio is a cloud business phone system with a web phone, call forwarding, and Calilio Hub prepaid calling packs for specific countries.
