351 Telephone Code: What You Need to Know
June 15, 2026

The 351 telephone code refers to a calling code used for dialing telephone numbers in Portugal. Understanding how this code works is essential for making calls to or from this country. In the global telecommunications network, each country has its own unique code that aids in connecting international calls, and 351 is specific to Portugal. This post provides a detailed overview of everything related to the 351 telephone code, ensuring you have all the information you need.

What it means / how it works

The 351 telephone code is the international dialing code for Portugal and is designated by the International Telecommunication Union (ITU). When dialing an international number to Portugal, you append this code before the local number, ensuring that your call reaches the correct destination. How does this work?

When you place a call from outside Portugal, you'll typically start with a ‘+’ symbol or the international call prefix of your country (for example, 011 in the USA), followed by 351 and then the local number. The code distinguishes your call as intended for Portugal's telephone network.

For instance, in the USA, if you want to call a Portugal number 912345678, you would dial +351 912345678 or 011 351 912345678. This routing helps networks understand the geographical direction of your call.

Practical scenarios

  • If a business in the USA wants to finalize a deal with a partner in Portugal, they will need to use the 351 code to reach them directly.
  • Vacationers planning a trip to Portugal may want to call hotels or tour operators. They'll need to include the 351 code for smooth communication.
  • If a family member in the USA wishes to contact relatives living in Portugal, they must include the 351 code.
  • Companies with remote teams might frequently communicate with employees in Portugal, requiring the use of the 351 code in cell phones or VoIP systems.
  • Customers calling technical support for a product or service based in Portugal must dial using the 351 code.
  • Participating in international conferences may demand contacting local numbers in Portugal, necessitating the 351 code for seamless connections.
  • Travel agents coordinating with local services in Portugal will include the 351 code to ensure they reach the right contact.
  • Non-profit organizations conducting outreach or aid in Portugal will dial 351 when attempting to connect with local contacts.

Step-by-step / how-to

Here’s a simple step-by-step guide to dial a number in Portugal from any country:

  1. Identify the international dialing prefix for your country (e.g., 011 for the USA).
  2. Dial the prefix followed by the 351 code.
  3. Next, enter the local number in Portugal, omitting any leading zero if it’s included. For instance, if the local number is 912345678, you would dial it as is after the 351 code.

For example, to call 912345678 in Portugal from the USA, you would dial:

011 351 912345678

Safety, privacy & legal considerations
