How to Make International Calls from a Landline

Understanding International Dialing Codes

When you call another country from a landline, you combine several parts: an international access code (also called an exit or IDD code), the country code, and the local number. Understanding each part prevents misdials and unexpected charges.

• International access code (IDD/exit code): This tells the telephone network you want to place an international call. Examples: 011 from the United States and Canada, 00 from most of Europe, 0011 from Australia, and 010 from Japan. Your country’s phone operator publishes the exact code.
• Country code: A short numeric code that identifies the destination country. Examples: 1 for the United States and Canada, 44 for the United Kingdom, 91 for India, 63 for the Philippines.
• Trunk prefix (local leading digit): Many countries use a leading 0 (or other digit) for domestic long-distance calls. You usually drop the trunk prefix when dialing from abroad. For example, a UK number written as 020 7946 0000 becomes +44 20 7946 0000 (drop the initial 0).
• Local number: The remainder of the number, which often includes area or city codes.

Standard international format follows E.164: + [country code] [national number]. For example:

• +1 212 555 0123 (New York, USA)
• +44 20 7946 0000 (London, UK)
• +91 80 1234 5678 (Bengaluru, India)

On a landline you rarely have a plus (+) key. Instead you dial your country’s exit code, then the country code, then the national number (without the trunk prefix). On a mobile phone you can often use + instead of the exit code by long-pressing the 0 key, which makes the number portable between countries.

If you call via an operator or a calling card, the provider may give you a different dialing sequence. Always check your landline carrier’s instructions for operator-assisted or premium international services.

Step-by-Step Guide to Dialing International Numbers

Below are clear steps for making an international call from a traditional landline and tips for dialing from a mobile if you prefer.

Step 1 — Verify the full international number

• Get the destination country code and the national number. Ask the person you’re calling to give the number in international format if possible (for example, +44 20 7946 0000).

Step 2 — Find your country’s international access code

• From the US or Canada: dial 011
• From most European countries: dial 00
• From Australia: dial 0011
• From Japan: dial 010 If you don’t know the code, check your landline provider’s website or search for “IDD code [your country]”.

Step 3 — Dial the sequence on your landline

1. Lift the handset (or press speakerphone).
2. Listen for a dial tone.
3. Dial the international access code.
4. Dial the destination country code.
5. Dial the national number, omitting any domestic trunk prefix (commonly a leading 0).
6. Wait for the call to connect.

Example: Calling a London landline (020 7946 0000) from the United States:

• Dial: 011 44 20 7946 0000

Example: Calling a Mumbai landline (022 1234 5678) from the UK:

• Dial: 00 91 22 1234 5678

Step 4 — Ending the call

• Hang up as you normally would. If your carrier charges by minute, be aware of rounding rules; some carriers bill by the minute, others by the second.

How to dial an international number on a landline if you only have the mobile format

• If someone gives you a number in + format (e.g., +91 98 7654 3210) but your landline requires an exit code, replace the + with your country’s IDD code:
  • +91 98 7654 3210 becomes 011 91 98 7654 3210 when calling from the US.

How to dial landline using mobile phone

• On a mobile, press and hold 0 to get the + symbol. Then dial + [country code] [national number]. Using + makes the number work whether you’re on local SIM or roaming.

Operator-assisted and special services

• If your landline uses an operator or international operator access number, follow your provider’s instructions. These services may add operator fees. Avoid them if you prefer lower-cost options.

Tips for Reducing International Calling Costs

International landline rates vary widely between providers and destinations. Use these practical tips to lower your bill.

1. Check your landline carrier’s published rates before you call

• Many carriers display per-minute or per-second rates online. Compare rates for the countries you call most.

2. Use Wi‑Fi calling or VoIP apps for lower per-minute costs

• VoIP apps call real phone numbers over the internet and usually cost less than traditional landlines. Many apps offer per-second billing and credit packs that reduce cost for frequent callers. If you call international landlines often, this can cut your bill significantly. See a deeper explanation in our guide to VoIP phone services explained.

3. Buy credit packs or flat-rate plans for heavy use

• Some VoIP providers offer credit packs with lower per-minute rates or flat-rate bundles for specific countries. Compare the per-minute price and terms. For example, some apps charge as little as $0.02/min to the US or $0.08/min to India on Wi‑Fi.

4. Use callback and calling-card services carefully

• Callback services can reduce costs but add steps: you initiate a request, then receive a call back that connects you internationally. Calling cards can be a good deal for specific destinations but watch for connection fees and rounding rules.

5. Make short, targeted calls and schedule them

• Call during off-peak hours if your carrier offers lower rates, and keep calls concise. Confirm time zones before dialling to avoid long waits and repeated calls.

6. Use local numbers and virtual numbers for frequent contacts

• If you call a business or frequent contact in another country, ask whether they can provide a local or toll-free number. Virtual phone numbers can give you a local presence in a different country and often cost less to call. Learn more in our virtual phone numbers guide and free virtual phone numbers.

7. Try apps that don’t require accounts or long contracts

• Some VoIP solutions let you buy credit and call without creating an account. That keeps things simple and removes recurring billing surprises.

8. Test rates with a short call

• Many services provide a free trial minute or low-cost initial calls. Use a short test call to check call quality and exact billing rules before lengthy conversations.

If you want a quick, affordable option to call international landlines, consider a VoIP app that lists per-minute rates and credit packs. They often give clearer pricing than traditional landline carriers and can save you money on frequent or long calls.

Common Mistakes to Avoid When Calling Abroad

Experienced callers still make avoidable errors. Watch for these common missteps.

• Dialing the trunk prefix from abroad: Including the domestic trunk prefix (often 0) after the country code leads to failed calls. Example mistake: dialing 011 44 020 7946 0000 instead of 011 44 20 7946 0000.
• Using the wrong international access code: Each country uses a different exit code. If you mistakenly dial the wrong one, the call won’t route or you’ll reach an operator.
• Not checking time zones: Calling someone in the middle of the night can force repeated hang-ups and call-backs, which increases cost if your provider bills per connection.
• Ignoring provider surcharges and minimums: Some carriers charge a connection fee or round up to the next minute. Know the billing increments (per-second vs per-minute) to estimate the real cost.
• Assuming mobile numbers and landlines use the same formatting: Mobile numbers often have different prefixes. Always verify the full international format for the number type you’re calling.
• Using operator-assisted calls without checking fees: Operators can add significant per-minute and connection fees. Use operator services only when necessary.
• Forgetting to remove spaces and special characters when dialing on a landline: While spaces improve readability, your landline will not accept letters or punctuation and may treat them as dial errors. Use digits only.

Avoiding these mistakes saves time and reduces unexpected charges.

Alternative Methods for International Communication

If you want to avoid traditional landline costs or increase reliability and flexibility, consider these alternatives.

VoIP apps and services

• VoIP apps place calls over Wi‑Fi or mobile data to both mobile and landline numbers. They often offer lower per-minute rates, credit packs, and per-second billing. For an overview of VoIP options and how they work, see our VoIP phone services explained. VoIP can provide better value than landlines for regular international calls.

Free online video calling platforms

• If the person you’re calling uses the same app and has internet access, video chat and voice-over-internet platforms can be free. See our comparison of free online video calling platforms. These services don’t call landlines unless the provider offers an outbound calling feature.

Virtual phone numbers

• Virtual numbers give you a local number in another country that forwards to your real phone. Use them to accept calls without international charges and maintain a local presence. Our virtual phone numbers guide explains options and costs. You can also find free virtual number options in free virtual phone numbers, though free services often limit features.

Calling cards and international plans

• Prepaid calling cards or special international plans from your landline carrier sometimes fit occasional callers. Compare per-minute pricing and fine print against VoIP alternatives before committing.

Use a hybrid approach

• Use VoIP to call landlines where it’s cheaper, and keep your landline for local or emergency calls. For an in-depth how-to on various methods, see our guide on how to make international calls.

If you prefer a simple app that lets you call international landlines without long contracts, check providers that clearly list per-minute rates, offer credit packs, and provide at least one free trial minute so you can test quality and cost before buying credit.
