DialPhone International calling guides

How to call any country from the US — dialing steps, country and exit codes, number formats, and business calling tips.

Placing a call from the US to another country follows a consistent pattern: the US exit code 011, then the destination country code, then the national number (usually dropping a leading zero). This cluster gives the exact dialing steps, country codes, and formatting for calling specific countries, plus the practical differences between mobile and landline dialing.

Read these if your team calls customers or suppliers abroad, you are setting up international dialing on a business line, or you just need the correct sequence to reach one specific country.

Methodology

How we research this cluster

Country codes and dialing formats are checked against ITU-T E.164 assignments and each destination country national numbering plan. Guides describe the dialing mechanics generically; where DialPhone calling coverage or rates are referenced, they reflect current published plan details rather than estimates.

Most articles in the international calling cluster get re-verified every 90 days against current vendor pricing pages, product documentation, and primary regulatory sources. Where a vendor changes pricing or feature scope between verification windows, the affected article is flagged in our editorial dashboard for immediate update. Last-modified dates on every article reflect the most recent verified-as-of date, not the original publication date. The full corrections log is summarized in the editorial standards page.

Cross-cluster reading: the business phone cluster covers fundamentals around cloud PBX migration, number porting, and AI-era voice features; the contact center cluster covers omnichannel routing, agent assist, and CCaaS evaluation; the UCaaS cluster covers platform strategy and migration playbooks; and the industry solutions cluster covers vertical-specific deployments. The communications glossary defines the terminology referenced across every cluster, and the open VoIP Pricing Research 2026 report grounds the pricing benchmarks.

Factual corrections: support@dialphone.com with the article URL and the specific claim. Errors get corrected publicly with visible last-updated dates and a brief change note in the article body where the original copy was material to the reader's decision.

FAQ: international calling

How do I call another country from the US?

Dial the US exit code 011, then the destination country code, then the local number. For most countries you drop the leading zero of the national number. For example, to call a UK number you dial 011 + 44 + the number without its leading 0. From a mobile you can usually replace 011 with a + sign.

What is the difference between an exit code and a country code?

The exit code (011 in the US) tells your carrier the call is leaving the country. The country code identifies the destination — 44 for the UK, 91 for India, 61 for Australia. You always dial the exit code first, then the country code, then the national number.
