How To Call Panama From The United States: A Complete International Dialing Guide
To call Panama from the United States, dial the international exit code 011, followed by the Panama country code 507, and then the specific 7-digit landline or 8-digit mobile number. Successful connection requires navigating the North American Numbering Plan (NANP) exit protocols and ensuring the destination number adheres to Panama’s National Numbering Plan managed by the Autoridad Nacional de los Servicios Públicos (ASEP).
Pre-Dialing Preparation and Infrastructure Requirements
Before initiating an international call to the Republic of Panama, it is essential to understand the technical framework of the connection. Panama operates outside the North American Numbering Plan (NANP), meaning it does not use the +1 country code shared by the US, Canada, and many Caribbean nations. Instead, Panama is part of the World Zone 5 for international calling.
Establishing a stable connection involves verifying both your hardware capabilities and your service provider’s international provisioning. High-latency connections or dropped calls often stem from a lack of "International Direct Dialing" (IDD) permissions on a standard US cellular or landline account.
Essential Checklist for International Connectivity
- Carrier Provisioning: Ensure your US-based service provider (e.g., AT&T, Verizon, T-Mobile, or VoIP providers like Vonage) has international calling enabled. Many prepaid plans block international outbound calls by default to prevent "bill shock."
- The Exit Code (011): This is the mandatory prefix for all international calls leaving the United States via the Public Switched Telephone Network (PSTN).
- The Destination Prefix (507): This is the ITU-T assigned country code for Panama.
- Local Number Structure: Panama transitioned its numbering system several years ago. Landlines are strictly 7 digits, while mobile numbers were expanded to 8 digits (starting with the digit '6').
- Time Zone Alignment: Panama operates on Eastern Standard Time (EST, UTC-5) year-round. Unlike the United States, Panama does not observe Daylight Saving Time (DST). From March to November, Panama is one hour behind US Eastern Daylight Time (EDT).
- Budgetary Considerations: Standard international rates can exceed $1.00 per minute on legacy landlines. Verify the per-minute rate or consider secondary VoIP protocols to minimize egress costs.
Technical Step-by-Step Execution for Calling Panama
Navigating the international gateway requires precise sequence input. Errors in the prefix or the omission of the exit code will result in a local "number not recognized" intercept message from your US carrier.
Step 1: Input the US International Exit Code
The first sequence in any outbound international call from a US landline or mobile device is the exit code. This signals to the local exchange that the subsequent digits should be routed to the international gateway rather than the domestic domestic switches.
- On a standard landline or numeric keypad, dial 011.
- If you are calling from a smartphone, you can replace "011" by long-pressing the 0 key to input a + symbol. The "+" functions as a universal exit code recognized by global GSM and LTE networks.
Step 2: Enter the Panama Country Code
Once the system recognizes an international request, you must specify the destination country.
- Enter 507.
- Do not add a 0 or any other prefix between the exit code and the country code.
Step 3: Determine the Destination Device Type (Landline vs. Mobile)
Panama uses a differentiated numbering system that allows callers to identify whether they are reaching a fixed-line or a cellular device. This is critical because many US carriers charge different rates for "Mobile Termination" compared to "Landline Termination."
- For Landlines: These numbers are 7 digits long. They typically begin with digits such as 2, 3, 4, 7, 8, or 9, depending on the province and the service provider (such as Cable & Wireless Panama or Tigo).
- For Mobile Phones: These numbers are 8 digits long. In 2008, Panama implemented a "6" prefix for all mobile numbers. If you are calling a cell phone, the number will always start with 6, followed by 7 additional digits.
Step 4: Finalize the Dialing Sequence
The complete string should be entered without pauses.
- To a Panama Landline: Dial 011-507-XXX-XXXX
- To a Panama Mobile: Dial 011-507-6XXX-XXXX
Step 5: Monitor the Handshake and Ringback Tone
After dialing the final digit, there may be a 3-to-7 second delay as the signal routes through undersea fiber optic cables (such as the ARCOS-1 or MAYA-1 systems that connect Panama to the US). You may hear a distinct ringback tone that differs slightly in cadence from the standard US double-ring. If the call fails immediately with a fast busy signal, the international trunk lines may be congested, or your carrier may be blocking the route.
Pro-Tip: If you are using a VoIP service like Skype, Google Voice, or Zoom Phone, you generally do not need to dial "011." You usually select "Panama" from a dropdown menu or dial "+507" followed by the number.
Warning: Be wary of "One-Ring" scams (Wangiri) originating from international codes. Only return calls to known Panamanian numbers to avoid high-cost premium-rate connection fees.

Common Connection Failures and Technical Remedies
Even with the correct digits, international calls can fail due to network mismatches or regional restrictions. Identifying the root cause is the first step toward a resolution.
Failure Scenario: The call drops immediately after dialing 011.
- Root Cause: Your US service provider likely has an "International Calling Block" on your account to prevent unauthorized charges.
- Actionable Fix: Log into your carrier's mobile app or call their customer service line to "provision" your line for international long distance.
Failure Scenario: You receive a "Number Not in Service" message despite having the correct digits.
- Root Cause: This is often caused by the "6" prefix requirement for mobile phones. If you were given a 7-digit mobile number, it is outdated.
- Actionable Fix: Prepend a "6" to the 7-digit mobile number to fulfill the 8-digit mobile numbering requirement mandated by ASEP.
Failure Scenario: Heavy echo or voice delay (latency) during the conversation.
- Root Cause: This occurs when the call is routed through low-quality "grey routes" or satellite links rather than Tier-1 fiber optic cables.
- Actionable Fix: Hang up and redial. This often forces the carrier to find a new, more efficient routing path through a different international gateway.
Failure Scenario: Call will not connect from a business PBX system.
- Root Cause: Many office phone systems require an extra digit (usually '9') to reach an outside line before dialing the international exit code.
- Actionable Fix: Dial 9, wait for the tone, then dial 011-507 and the number.
Frequently Asked Questions
Do I need to dial an area code for Panama?
Panama does not use internal area codes in the same way the United States does. The country code 507 covers the entire nation, including Panama City, Colón, and David. The first few digits of a 7-digit landline number technically indicate the region, but they are dialed seamlessly as part of the local number.
How much does it cost to call Panama from a US cell phone?
Costs vary significantly by provider. Major carriers like Verizon or AT&T may charge between $1.00 and $3.00 per minute on standard plans. However, most offer "International Add-ons" for approximately $10 to $15 per month that reduce the rate to $0.05 per minute or include it in an unlimited global calling tier.
Can I use WhatsApp to call Panama for free?
Yes, WhatsApp is the dominant communication platform in Panama. As long as both the caller in the US and the recipient in Panama have the app installed and an active internet connection (Wi-Fi or cellular data), the call is free. You must save the Panama number in your phone's contacts in the format +507-6XXX-XXXX for it to appear in the WhatsApp contact list.
Is there a difference between calling a landline and a mobile phone in Panama?
Yes, the primary difference is the number of digits and the cost. Landlines are 7 digits, while mobile phones are 8 digits and start with the number 6. Technically, mobile termination rates (the fee your carrier pays to the Panama carrier) are higher for mobile phones, which may be reflected in your monthly bill.
What is the best time of day to call Panama?
Because Panama is on EST (UTC-5) and does not observe Daylight Saving Time, you must calculate the difference based on the time of year. If it is summer in the US (Daylight Saving Time), Panama is one hour behind the US East Coast. If it is winter, Panama is at the same time as the US East Coast. Calling during business hours (8:00 AM to 5:00 PM) is recommended for professional inquiries.
