For many Americans, the world of international calling can seem a bit daunting. Between dialing prefixes, area codes, and country codes, it’s easy to get lost in the numbers. However, with a little understanding, connecting with friends, family, or business contacts across borders becomes much simpler. One such important piece of information is the country code 51, which unlocks communication with the vibrant and culturally rich nation of Peru.

What is a Country Code?
Before diving into the specifics of country code 51, let’s clarify what a country code actually is. In essence, it’s a numeric prefix that identifies a specific country for the purpose of international direct dialing (IDD). Every country has its own unique code, which is dialed before the local area code and the subscriber’s phone number. This system allows international telephone networks to route calls to the correct destination worldwide. Think of it like an international zip code for your phone call.
The Significance of Country Code 51
When you see country code 51, your immediate thought should be Peru. This South American nation, famous for its ancient Incan ruins, stunning Andean landscapes, and delectable cuisine, is increasingly connected to the United States through tourism, business, and personal relationships. Whether you’re planning a trip to Machu Picchu, conducting business with a Peruvian company, or simply catching up with a friend who has moved there, knowing country code 51 is the first step to making that connection.
How to Dial Peru from the United States
Making a call to Peru from the US involves a few simple steps. It’s crucial to follow this sequence to ensure your call goes through successfully:
- Dial the International Access Code (011): This is the universal code used in the United States to indicate that you are making an international call. You must dial 011 before any country code.
- Dial the Country Code (51): After the international access code, you will dial country code 51 to specify Peru as your destination country.
- Dial the Area Code: Within Peru, different regions have their own specific area codes. These are typically one or two digits. For example, Lima’s area code is 1, Cusco’s is 84, and Arequipa’s is 54. It’s important to know the correct area code for the specific city or region you are trying to reach.
- Dial the Local Phone Number: Finally, you will dial the local seven-digit or eight-digit phone number of the person or business you wish to contact.
So, a complete international call from the US to Peru would look something like this: 011 + 51 + Area Code + Local Phone Number.

Common Challenges and Tips for International Calling
Even with the correct codes, international calling can sometimes present challenges. Here are a few tips to help ensure a smooth connection:
Time Zones
Peru observes Peru Time (PET), which is UTC-5. This means there’s a time difference to consider when calling from the United States. For example, if you’re calling from New York (Eastern Time, UTC-4), Peru will be one hour behind. If you’re calling from California (Pacific Time, UTC-7), Peru will be two hours ahead. Always check the current time in Peru before placing your call to avoid inconvenient ringing times.
Mobile vs. Landline Numbers
While the dialing process for mobile and landline numbers in Peru is largely the same, be aware that mobile numbers often begin with a specific prefix after the area code (e.g., 9 for mobile numbers in many regions). If you’re unsure, it’s always best to confirm with the recipient or look up the specific numbering plan for Peru.
Cost of International Calls
International calls can be expensive, especially if you’re using a traditional landline service. Consider these options to manage costs:
- VoIP Services: Services like Skype, Google Voice, or WhatsApp allow you to make calls over the internet, often at significantly lower rates or even for free if both parties are using the same app.
- International Calling Plans: Many US mobile carriers offer international calling plans or add-ons that provide discounted rates to specific countries, including Peru. Check with your provider for available options.
- Prepaid Calling Cards: These cards can offer competitive per-minute rates for international calls and can be a good option for infrequent callers.
Dialing from a Cell Phone
When dialing from a cell phone, you can often use a “+” symbol instead of the 011 international access code. So, to call Peru, you would dial +51 + Area Code + Local Phone Number. The “+” symbol is a universal international direct dial prefix that your phone recognizes.
Beyond the Numbers: Cultural Considerations
While knowing the numbers is essential, remember that you’re connecting with people in a different culture. A few cultural considerations can enhance your communication:
- Formalities: Depending on your relationship, a slightly more formal tone might be appreciated in initial business calls.
- Patience: Internet and phone infrastructure can vary, so be prepared for occasional connection issues or delays.
- Language: While many Peruvians, especially in tourist areas, speak English, Spanish is the official language. A few basic Spanish phrases can go a long way.
conclusion
understanding and utilizing country code 51 is your gateway to seamless communication with Peru. By familiarizing yourself with the dialing process, considering time differences, and exploring cost-effective calling methods, you can confidently connect with this fascinating South American nation, bridging geographical gaps and fostering stronger connections.
