How to call Peru | In-depth guide with examples

Peru is one of South America's fastest-growing economies, with a booming mining and natural resources sector, a thriving tourism industry anchored by Machu Picchu and the Inca Trail, and a growing technology and outsourcing sector centered in Lima. Peru's large diaspora community in the United States — particularly in Florida, New Jersey, and California — means that personal international calls are a constant need. Meanwhile, business connections between U.S. firms and Peruvian partners in industries from mining to software development drive high volumes of professional calls.

Whether you're coordinating with business partners in Lima's financial district, reaching tour operators in Cusco, or staying in touch with family in Arequipa or Trujillo, understanding how to place an international call to Peru correctly is essential.

Guide to calling Peru

Before dialing, ensure you're aware of the rates charged by your carrier for international calls to Peru. You should also make sure your connection is reliable to avoid any issues caused by latency or choppy voice transmission.

1. Check the time in Peru

Peru is in the Peru Time Zone (PET), which is UTC-5. Peru does not observe Daylight Saving Time, so the offset is consistent year-round (though it shifts relative to U.S. cities that do observe DST):

• Eastern Time (ET): Peru is the same as ET in winter; 1 hour behind EDT in summer
• Central Time (CT): Peru is 1 hour ahead of CT; same as CDT in summer
• Mountain Time (MT): Peru is 2 hours ahead of MT
• Pacific Time (PT): Peru is 3 hours ahead of PT

Business hours in Lima (8 AM–6 PM PET) overlap well with morning hours in the Eastern and Central U.S.

2. Dial the exit code

For international calls from the U.S., the exit code is 011, indicating you're making an international call.

3. Enter Peru's country code

Next, dial Peru's country code, which is +51, to connect your call to Peru.

4. Dial the area code and local number

Start with 011, followed by 51, the country code for Peru.

For a landline

Peruvian landlines use an area code. Lima's area code is 1 (written as 01 locally — drop the leading zero internationally). Other areas include Arequipa (54), Cusco (84), Trujillo (44), and Chiclayo (74).

Lima landline numbers are 7 digits. To call a Lima landline (01) 432-5678, dial: 011-51-1-432-5678.

For a mobile phone

Peruvian mobile numbers are 9 digits and always begin with 9 (e.g., 987-654-321). There is no area code for mobile phones. To call a Peruvian mobile number 987-654-321, dial: 011-51-987-654-321.

Tips for a successful call

1. Mobile numbers always start with 9. This makes it easy to identify whether you're calling a landline (area code + 7 digits) or mobile (9-digit number starting with 9). The dialing format differs slightly between the two.

2. Lima's daytime hours overlap well with U.S. mornings. Since Peru doesn't observe DST, business calls are relatively predictable. A 9 AM ET call reaches Lima at 9 AM local time in winter — a convenient overlap for U.S. East Coast businesses.

3. Be prepared for regional infrastructure variation. Lima has excellent telecommunications infrastructure, but calls to remote regions like the Amazon basin or high Andes may be less reliable. In these areas, mobile connectivity often outperforms landlines.

4. Peruvian business culture values formality. Initial business calls in Peru tend to be formal. Use titles and surnames until invited otherwise, and take time to build rapport before getting to business. Spanish-language greetings are appreciated even if the conversation is in English.
