How to Call Colombia from the US
Colombia changed the way its phone numbers look in 2022, and the old seven-digit landlines you may have scribbled down years ago no longer connect. This guide walks through the +57 country code, the new 10-digit format for both landlines and mobiles, the time difference, and the cheapest reliable way to reach a Colombian number, straight from your browser, with nothing to install.
Colombia's country code and the 2022 numbering change
Colombia's country calling code is +57. From a US phone you dial the international format as 011 + 57 + the 10-digit Colombian number. From a browser service like Phonecall you just enter + 57 and the number, and the exit code is added for you, so the same saved contact works whether you are home in the US, traveling, or abroad.
In 2022 Colombia moved every fixed line to a uniform 10-digit format. Landlines now begin with 60 plus a single region digit: Bogotá fixed lines start 601, Medellín 604, Cali 602, and Barranquilla 605. Mobile numbers are also 10 digits and always start with a 3. If you have an old number that is only seven or eight digits long, it will fail, you need to rebuild it in the new format before dialing.
- Bogotá landline: +57 601 XXX XXXX
- Medellín landline: +57 604 XXX XXXX
- Cali landline: +57 602 XXX XXXX
- Any Colombian mobile: +57 3XX XXX XXXX
Time difference between the US and Colombia
Colombia runs on Colombia Time, UTC-5, and the whole country sits in a single time zone. Crucially, Colombia does not observe daylight saving time, so its clock never moves. That makes the math seasonal: in winter Colombia matches US Eastern exactly, and in summer, when most of the US springs forward, Colombia is one hour behind Eastern, two behind nowhere because it simply stays put.
In practice that means a call placed at noon in New York reaches Bogotá at either noon or 11 AM depending on the season. A comfortable window to catch family at home or a business open is roughly 9 AM to 8 PM Colombia Time, which lines up neatly with daytime hours anywhere in the continental US.
The cheapest way to call Colombia from the US
US carriers bill Colombia as an international destination, and without an add-on the per-minute charge to a Colombian mobile climbs quickly. There is a large Colombian community in the United States, heavily concentrated in South Florida and the New York and New Jersey area, and for the steady rhythm of family check-ins and small-business calls those carrier rates add up over a month.
A browser-based VoIP call routes over the internet directly to the Colombian carrier, so you pay only the destination rate, a few cents a minute, shown on screen before you dial. Phonecall bills per second instead of rounding up to the next minute, has no monthly fee and no minimum top-up, and gives every new account one free 60-second call. App-to-app calling on WhatsApp is free too, but it only reaches someone with the app open on a smartphone, it will not connect to a Colombian landline, a bank, or a clinic reception desk.

Frequently asked questions
What is the country code for Colombia?
Colombia's country code is 57. From the US you dial 011 + 57 + the 10-digit number on a regular phone, or simply + 57 and the number from a browser-based service like Phonecall.
Why does my old Colombian landline number no longer work?
In 2022 Colombia switched every fixed line to a 10-digit format. Landlines now start with 60 plus a region digit, for example 601 in Bogotá or 604 in Medellín. An old seven-digit number must be converted to the new format before it will connect.
What is the time difference between the US and Colombia?
Colombia is on UTC-5 year-round and does not use daylight saving time. It matches US Eastern in winter and is one hour behind Eastern in summer when the US is on daylight saving time.
How do I tell a Colombian mobile from a landline?
Both are 10 digits, but a Colombian mobile always starts with the digit 3, while a landline starts with 60 and a region digit. The dialing format, +57 then 10 digits, is identical for either.
Calling Colombian landlines vs mobiles
Rates to Colombian landlines and mobiles differ slightly, and Phonecall shows the exact figure for the number you typed before you connect. Whichever you are calling, the format is the same, +57 and 10 digits, and the call runs over carrier-grade HD voice, so a relative in Medellín or an office in Bogotá hears you clearly.
