How to Use the +354 Country Code: A Guide for SMBs and Startups

Whether you’re expanding into Reykjavík or supporting a partner in Akureyri, knowing how to correctly dial and format Icelandic phone numbers is key to effective global communication.

This guide walks you through everything you need to know about the +354 country code, how Icelandic phone numbers work, and how a cloud phone system like DialLink can simplify international business calling and messaging.

What Is the 354 Country Code?

+354 is the country code for Iceland. Unlike countries with area codes tied to regions, Icelandic phone numbers follow a closed numbering plan with fixed-length formats, meaning no additional area code is needed.

Here’s how Icelandic numbers are structured:

• Country Code: +354
• Number Format: +354 XXX XXXX

That’s it — just 7 digits after the country code, whether it’s a mobile, landline, or corporate number. There are no geographic codes or extensions needed when calling within Iceland.

Common Pitfalls in International Number Formatting

When SMBs and startups manage cross-border communications, even small errors in number formatting can cause failed calls, misrouted messages, or CRM issues. Here are some common mistakes to avoid when working with Icelandic phone numbers:

• Leaving out the country code (+354): Omitting this will result in failed calls when dialing internationally.
• Assuming Iceland uses area codes: Iceland’s numbering plan does not include regional codes, don’t add extra digits.
• Mixing local and international formats: For VoIP, CRMs, and SMS platforms, consistency matters, use E.164 format (e.g., +3545123456) to avoid syncing issues.
• Assuming toll-free prefixes work the same as in the US: Iceland does not use 1-800 or 1-888 numbers; its toll-free services use different prefixes like 800.

Standardizing phone number formats across your systems ensures a smoother, more professional communication experience.

Common Icelandic Number Format Examples

Note: Toll-free numbers beginning with “800” work domestically. Calls from outside Iceland may not be toll-free and could be blocked by some carriers.

How to Read and Format Icelandic Numbers

All phone numbers in Iceland are made up of 7 digits following the +354 country code. The first digit after the country code indicates the type of service:

• 3, 4, 5: Landlines
• 6, 7, 8: Mobile numbers
• 800: Toll-free numbers
• 900: Premium-rate numbers

Format Variations

• International Format (E.164): +3545123456 — ideal for CRMs, call software, and standardized contact storage
• Local Format (within Iceland): 512 3456 — used for domestic dialing
• International Dialing (outside Iceland): 00 354 512 3456 — when “00” is the exit code (e.g., from the UK or EU countries)

Best Practices for SMBs

• Always use the full international format (+354 XXX XXXX) for consistency
• Save numbers in E.164 format across all tools to avoid failed calls or duplicate contacts
• Double-check toll-free numbers—what’s free domestically in Iceland may incur charges when dialed internationally
• Use CRM integrations like those provided by DialLink to automate call logging and avoid manual formatting errors

Consistent, standardized formatting helps teams work faster, avoid communication errors, and maintain a professional customer experience.
