Calling Colombia from United States

Dial 011 (the United States exit code), then 57 (Colombia’s country code), then the local number with its leading 0 removed. So +57 601 234 5678 is dialled as 011 57 601 234 5678. From a mobile you can dial +57 directly instead of 011.
Dialling Colombia from United States: start with 011, the exit code for United States, then 57 for Colombia, then the local number with its leading 0 dropped. The diagram shows those three blocks and the leading-zero rule that catches most people out.
The + shortcut on a mobile replaces the exit code entirely, which is why it works on any SIM in any country.

Step by step

Dialing Colombia from United States

Four steps, and the third one is where almost every failed call goes wrong.

  1. 1

    Dial 011: the exit code for United States

    011 tells the United States network that the call is leaving the country. On a mobile you can press and hold 0 to type a + instead, which works from any country and any SIM; it is the more reliable option when you travel.
  2. 2

    Dial 57: the country code for Colombia

    57 is Colombia's country calling code. It never changes and is the same no matter where you are calling from.
  3. 3

    Drop the leading 0 from the local number

    Numbers written for domestic use in Colombia begin with 0. That digit is a national trunk prefix and is not part of the number. Remove it: +57 601 234 5678 is dialled as 601 234 5678 after the country code.
  4. 4

    Check the local time before you dial

    Colombia is on COT (UTC−5, no DST) and United States is on ET (UTC−5/−4). Work out the overlap before calling; the most common cause of an unanswered international business call is simply the hour.

One thing about Colombia

Colombia moved to fixed 10-digit dialling in 2022: every landline now starts 60 followed by the old single-digit city code.

Frequently asked questions

How do I call Colombia from the United States?
Dial 011, then 57, then the local number with its leading 0 removed. For example, +57 601 234 5678 is dialled as 011 57 601 234 5678.
What is the country code for Colombia?
+57. From United States you reach it by dialling 011 first, or by dialling + directly from a mobile.
Do I include the 0 when calling Colombia?
No. The leading 0 is only used inside Colombia. Including it from abroad is the most common reason the call fails to connect.
How do I call a Colombia mobile from United States?
Exactly the same way as a landline: 011 + 57 + the mobile number without its leading 0. A Colombia mobile in international format looks like +57 320 123 4567.
What is the time difference between United States and Colombia?
United States is on ET (UTC−5/−4) and Colombia is on COT (UTC−5, no DST). Because several of these zones observe daylight saving on different dates, check the current offset rather than assuming a fixed gap.
Is it cheaper to call Colombia over the internet?
Usually, yes. Carrier international rates are typically far above VoIP per-minute rates, and calling from an owned local number also means the person you are calling sees a number they can ring back.
