What exit code do I dial from a Colombian landline to call the US?

Colombia uses carrier-specific exit codes for landline international calls. Common codes include 005 (ETB), 007 (Orbitel/Tigo), and 009 (Movistar). Check with your landline provider for the correct code. From a mobile phone, simply use the + symbol.

During Eastern Daylight Time (Mar–Nov), the East Coast is 1 hour ahead of Colombia. The US West Coast is 2–3 hours behind Colombia depending on the season.

The most common reasons are: (1) using the wrong carrier exit code on a landline, (2) missing the US country code +1, (3) dialing an incomplete 10-digit US number, or (4) your mobile plan doesn't include international calling. Verify each step, or try calling via Sayfone in your browser to bypass carrier issues.

What US area codes are common for Colombian diaspora communities?

Large Colombian communities in the US are concentrated in cities like Miami (305/786), New York (212/718/347), Los Angeles (213/323), and Houston (713/832). These are among the most frequently dialed area codes from Colombia.

DIALING GUIDE

Step-by-Step: Calling the US from Colombia

Follow these steps to dial any US landline or mobile number from Colombia. The process differs slightly depending on whether you're calling from a Colombian mobile phone or a landline.

1
Dial the international exit code
From a Colombian mobile phone, press and hold 0 to get the + symbol — this replaces the exit code. From a Colombian landline, dial your carrier's specific exit code: 005 (ETB), 007 (Orbitel/Tigo), or 009 (Movistar), among others.
```
Mobile: + | Landline (Movistar): 009
```
2
Enter the US country code
Dial 1 immediately after the exit code or + symbol. This routes your call to the United States telephone network.
```
+ 1 or 009 1
```
3
Dial the 3-digit US area code
Every US phone number begins with a 3-digit area code that identifies the region. Common area codes for cities with large Colombian communities include 305 (Miami), 212 (New York), and 213 (Los Angeles).
```
+ 1 305
```
4
Dial the 7-digit local number
Complete the call by entering the remaining 7 digits of the US phone number. The full US number is always 10 digits (area code + local number).
```
+ 1 305 555 1234
```
Press call or use Sayfone from your browser
If dialing from your phone's keypad, press the call button. Alternatively, use Sayfone in your browser to call any US number at $0.08/min — no app download required.

IMPORTANT RULES

Dialing Rules for Calling the US from Colombia

Keep these rules in mind to avoid failed calls and ensure your connection goes through on the first attempt.

Colombia uses carrier-specific exit codes on landlines

Unlike most countries that use a universal exit code (like 00), Colombia requires you to dial your specific carrier's exit code from a landline: 005 (ETB), 007 (Orbitel/Tigo), 009 (Movistar), among others. From a mobile phone, simply use the + symbol.

US numbers are always 10 digits after the country code

All US phone numbers follow the format: 3-digit area code + 7-digit local number. Both landlines and mobile numbers use this same 10-digit format. There is no distinction in format between mobile and landline numbers in the US.

Do not add a leading 0 before the US area code

When dialing internationally, go straight from the US country code (1) to the area code. Adding a 0 before the area code is a common mistake that will cause the call to fail.

The + symbol replaces the exit code on mobile phones

On most Colombian mobile phones, press and hold the 0 key to produce the + symbol. This universally replaces any carrier-specific exit code and simplifies international dialing.

US area codes can change — verify before calling

Some US cities have multiple area codes, and new ones are added periodically. If a number you've been calling no longer connects, the area code may have changed. Confirm the current area code with your contact.

TIMING & TIPS

Best Times to Call the US from Colombia

Colombia (COT, UTC−5) shares the same base offset as the US Eastern time zone. However, the US observes daylight saving time and Colombia does not, which shifts the gap by one hour for part of the year.

🇺🇸

During US Eastern Daylight Time (mid-March to early November), New York and Miami are 1 hour ahead of Bogotá. During US Eastern Standard Time (November to March), the clocks are synchronized. The US spans multiple time zones, so if you're calling the West Coast (Pacific Time), expect a 2–3 hour difference from Colombia.

Time & windows

US East Coast (EST/EDT)

Same time or +1 hour from Colombia

New York, Miami, Washington DC — during EDT (Mar–Nov), they are 1 hour ahead of Bogotá

US Central (CST/CDT)

−1 hour or same time from Colombia

Houston, Chicago, Dallas — during CDT they match Colombia; during CST they're 1 hour behind

US West Coast (PST/PDT)

−2 to −3 hours from Colombia

Los Angeles, San Francisco, Seattle — 2 hours behind Colombia during PDT, 3 hours during PST

Calling tips

Colombia does not observe daylight saving time, so the time difference with the US shifts twice a year — double-check before calling.
If you regularly call family in Miami or New York, set a recurring reminder for a time that works year-round, such as 7:00 PM COT.
Weekend mornings in Colombia (9:00–11:00 AM COT) are great for catching US East Coast contacts before their day gets busy.
Use Sayfone from your browser to avoid carrier surcharges on international calls from Colombian mobile plans.

Business etiquette

US business calls typically start and end on time. Dial in a minute or two early if joining a scheduled call.
In a business context, a brief greeting followed by the agenda is expected — get to the point after initial pleasantries.
If calling a US office, be aware of automated phone trees. Have the extension number or department name ready.
For trade-related calls, note that US business contacts in import/export may prefer email follow-ups after an initial phone conversation.

TROUBLESHOOTING

Common Issues When Calling the US from Colombia

If your call to the US isn't connecting, review these common problems and solutions.

Wrong or missing exit code from a Colombian landline

Colombia's landlines require a carrier-specific exit code (005, 007, 009, etc.), not a universal 00. Using the wrong code for your carrier will cause the call to fail. Check with your landline provider or switch to a mobile phone and use the + symbol.

Incomplete US number

US numbers must include all 10 digits after the country code — a 3-digit area code plus a 7-digit local number. If you're missing the area code or have too few digits, the call won't connect.

Your Colombian mobile plan may not include international calling

Some prepaid Colombian mobile plans restrict international calls by default. Contact your carrier (Claro, Movistar, Tigo) to confirm international calling is enabled, or use Sayfone via your browser to bypass carrier restrictions entirely.

Call goes to a US voicemail or automated system

Many US numbers, especially business lines, route to voicemail or automated phone trees. This is normal — leave a message or navigate the menu. Having the recipient's extension number ready can save time.

Audio quality issues or dropped calls

If you experience poor audio on a traditional call, try calling during off-peak hours or use a VoIP-based service like Sayfone over a stable Wi-Fi or data connection for clearer audio quality.
