How to Call Portugal from the US: A Guide for SMBs and Startups

You’re about to follow up with a digital marketing agency in Lisbon or confirm delivery details with a supplier in Porto — and suddenly, you're wondering: What’s the correct way to call Portugal from the US? 

If you're part of a growing business working with clients, remote partners, or vendors in Portugal, this guide walks you through the essentials — from dialing formats to smart tools that make international calling simple and cost-effective. 

What’s the Portugal Country Code? 

The country code for Portugal is +351. When calling from the US, you’ll need to dial this after the international exit code to make sure your call is routed correctly to Portugal. 

How to Call Portugal from the US, Step by Step 

Here’s how to dial a phone number in Portugal from the United States: 

For Portuguese Landlines: 

1. Dial 011 – This is the US exit code. 
2. Dial 351 – This is the Portugal country code. 
3. Dial the area code (including the first digit). 
4. Dial the local number. 

Example: To call a landline in Lisbon (area code 21), dial: 011-351-21-1234567. 

For Portuguese Mobile Phones: 

1. Dial 011 or use “+” on your mobile phone. 
2. Dial 351 (Portugal’s country code). 
3. Dial the full mobile number (starting with 9). 

Example: If the number is 912-345-678, you would dial: 011-351-912-345678. 

Bonus Tip:  

Press and hold the “0” key to insert a “+” instead of dialing 011. That means you can dial +351-912-345678 and hit call.
