How do I dial a +352 number from Colombia?

Dial 00 plus your carrier code, then 352 and the local subscriber number. +352 is Luxembourg, not the US. On a Claro SIM the full sequence is 00 444 352 followed by the 8 or 9 digit Luxembourg number. On a smartphone, just dial +352 and the number; the SIM translates the + automatically. Luxembourg fixed lines are 8 digits after the country code, mobiles are usually 9 digits starting with 6. Rates from Colombian carriers to Luxembourg run higher than US calls, typically $800 to $1,200 COP per minute. A browser dialer can reach Luxembourg landlines at around $0.04 to $0.08 USD per minute.

Can I receive US calls on my Colombian SIM for free?

No. Incoming international calls on a Colombian SIM are billed as domestic minutes against your plan in most cases, which is effectively free on Tigo and Movistar postpaid pero counts against your prepaid balance on Claro and WOM. The caller pays the international rate from their US carrier. The catch is that some prepaid plans bill incoming international calls at a higher rate than incoming domestic; check with *611 on Claro. If you want a US number that rings on Colombian data, Google Voice gives free incoming calls to US-issued numbers, but you have to set the account up while physically in the US.

Does Colombian DST change my US calling window?

Colombia does not observe daylight saving time, so the gap shifts twice a year when the US moves. From mid-March through early November, Colombia is on UTC-5 while US Eastern is on UTC-4, making Bogota one hour behind New York. From November through mid-March, Colombia and US Eastern align. Practically: a 10 AM Bogota call in July reaches New York at 11 AM, and the same call in January reaches New York at 10 AM. For West Coast institutions, subtract two or three hours from Bogota depending on the season. The IRS opens 6 AM ET, which is 5 AM or 6 AM in Bogota.

Will my Claro pack minutes work to call US mobiles too?

Yes, Claro's LDI packs apply to both US landlines and US mobile numbers in the +1 country code, including Hawaii and Alaska. They do not cover US toll-free 800, 888, 877, 866, 855, 844, or 833 prefixes; those route at the rack rate of $499 COP per minute even when you have a pack active. Pack minutes also cannot be used to Canada, even though Canada shares the +1 country code; Canada falls under a separate "US and Canada" pack on Claro, not the US-only one. Check your plan terms before assuming a Toronto call is covered. The 150-minute pack expires 30 days after purchase.

How to Call US from Colombia (Cheapest Way 2026)

To call the US from Colombia, dial 00 + your carrier's code + 1 + the US area code + the 7-digit number. On a mobile phone, dial + instead of the long prefix and your carrier routes automatically — +1 305 555 1234 reaches a Miami number from any Colombian SIM. The wrinkle: your carrier code depends on which SIM you have. Claro = 00444, Movistar = 009, Tigo = 00414 (mobile) or 005 (landline), ETB = 007, and WOM lets you dial raw + with no code at all.

What you'll pay to call the US from Colombia depends on the carrier and whether you've bought a long-distance pack. Claro charges $499 COP per minute without a pack — about $0.13 USD. Movistar prepaid runs $629 COP per minute. Tigo includes US calling free on its default postpaid plans, which is a real bundle. Here's the full dialing format, the rates, and how to pay $0.04 a minute instead.

How to Dial the US from Colombia

From Colombia, dial 00 + your carrier's code + 1 + the US area code + the 7-digit number.

Dial 00 (the international access prefix)
Dial your carrier code — 444 for Claro, 9 for Movistar, 414 for Tigo, 7 for ETB
Dial 1 (US country code)
Dial the 3-digit US area code
Dial the 7-digit phone number
Example on Claro mobile: 00 444 1 305 555 1234 reaches a Miami line

On a smartphone, you can replace the whole 00 + carrier-code combo with just + and the carrier routes through its own long-distance gateway by default. +1 305 555 1234 works on Claro, Movistar, and Tigo SIMs and gets you to the same place. WOM is built around the + dial — there's no separate CSP code to remember.

If you've seen guides telling you to dial 011, that's the US exit code — used when calling FROM the US, not from Colombia. From a phone in Bogotá or Medellín or Cali, you dial 00 plus your carrier's prefix. From a landline, no shortcut — you have to dial the full code.

Which Carrier Code Do I Dial?

Your carrier code depends on which Colombian SIM or landline you're calling from. Most other countries have one international exit code. Colombia has six, one per long-distance carrier — a quirk inherited from the late-1990s telecom deregulation that nobody has fully unwound.

Carrier | Mobile prefix | Landline prefix

Claro | 00444 | 00456

Movistar | 009 | 009

Tigo | 00414 | 005

ETB | 007 | 007

WOM | + (no code) | —

On a mobile phone, dialing + routes you through your own carrier's long-distance service automatically, so most users never type the four-digit code. The code matters on landlines, on dual-SIM phones where you want a specific route, and on legacy handsets without + support. Dial the wrong CSP from a Claro SIM and the call may fail or route at a third-party rate — Claro will only let you out through its 00444 gateway by default.

ETB on 007 is mostly a Bogotá landline play. Tigo's 005 code is the legacy UNE-EPM landline route still recognized on Tigo-Hogar lines.

Claro, Movistar, Tigo Rates to the US

Without a pack, Colombian carriers charge $324 to $629 COP per minute to call the US. With a pack, the per-minute rate drops dramatically — and Tigo postpaid bundles US/Canada/Puerto Rico calls for free.

Carrier / Plan | Rate to US (COP/min) | USD equivalent (at 3,750 COP/USD)

Claro Móvil prepaid — rack rate | $499/min | ~$0.13/min

Claro Móvil — 10-min prepaid pack ($2,000) | $200/min | ~$0.053/min

Claro Móvil — 150-min prepaid pack ($7,000) | $47/min | ~$0.013/min

Claro Móvil — postpaid pack | "From $79/min" | ~$0.021/min

Movistar postpaid — standard ISD | $519/min (incl IVA) | ~$0.14/min

Movistar prepaid — standard ISD | $629/min (incl IVA) | ~$0.17/min

Tigo postpaid (default plans) | $0 / free to US, CA, PR via 00414 | $0

Tigo prepaid / out-of-pack | From $324/min | ~$0.086/min

ETB | From $380/min | ~$0.10/min

WOM | From $350/min | ~$0.093/min

WorldDialer (browser) | ~$75/min | $0.04/min

Two things stand out. Claro's 150-minute pack at $7,000 COP works out to $47 per minute — that's roughly $0.013 USD, cheaper per minute than WorldDialer. But you have to use all 150 minutes inside the validity window or the unused balance evaporates. If you're calling the US three times a year about a Chase fraud alert, that pack is a poor fit. You use 20 minutes, the rest expires, and you do it again next quarter.

Tigo postpaid is the genuinely competitive bundle in the series so far. If you're on a Tigo pospago plan, US/Canada/Puerto Rico calls are included free through 00414. That's a real free, not a marketing free. WorldDialer's $0.04/min beats every Colombian carrier's rack rate, ties Claro's biggest pack, and loses to Tigo pospago on raw math. The honest pitch: if you're not already on Tigo pospago — and most Claro and Movistar customers aren't — WorldDialer is the no-pack, no-plan alternative.

Do US Toll-Free Numbers Work from Colombia?

US 1-800 numbers will ring from Colombia, but they aren't toll-free — your carrier bills them at full international rates.

This applies to every US toll-free prefix: 1-800, 1-888, 1-877, 1-866, 1-855, 1-844, 1-833. Dial 00 444 1 800 xxx xxxx from a Claro mobile and the call connects, but Claro bills you $499 COP per minute as if it were a normal long-distance call to the US. The "free" only applies inside the US. Some mobile networks also route inconsistently to certain toll-free prefixes — Latin American mobile carriers are documented to occasionally surcharge or block 1-800 traffic.

The fix: find the company's direct +1 (NXX) number. Banks, the IRS, USCIS, and the SSA all publish a non-toll-free line for international callers. Those numbers route from any Colombian network at the same per-minute rate as any other US call — and far less through a browser service.

Your Options for Calling the US from Colombia

You have four ways to call the US from Colombia. Most are designed to be paid for whether you use them or not.

Method | Cost | Setup | Best For

Carrier — rack rate (no pack) | $324-$629 COP/min | None | Single emergency call

Carrier — LDI pack | $47-$200 COP/min | Buy pack, watch validity | Daily callers who'll burn the minutes

Carrier — Tigo pospago bundle | $0 to US/CA/PR | Be on a Tigo pospago plan | Existing Tigo pospago customers

VoIP subscription (Skype legacy, Vonage) | ~$10-$30 USD/mo + per-min | App, account, credit card | Frequent callers

WorldDialer (browser) | $0.04 USD/min | None | Occasional callers

VoIP subscriptions assume you call internationally every week. Most Colombian users with US ties don't — you're in Bogotá, you need to sort a Chase fraud alert, then you don't dial a US number for three months. Paying $15 a month for that is paying for the months you don't call.

LDI packs have the same problem in pesos. Claro's $7,000 COP 150-minute pack buys 150 minutes — at the rack-pack rate ratio it's a real discount. If you use 20 of them, you've paid $7,000 for $1,000 worth of calls and the rest expires in 30 days.

WorldDialer runs in a browser. No app. No pack. No monthly subscription required. Open the tab, add credits, make the call. $0.04 a minute to US landlines, the same rate whether you're in Cartagena or Medellín or anywhere else.

US Phone Numbers You'll Actually Need from Colombia

These are the non-toll-free US numbers that work from any Colombian network. Bookmark them. The 1-800 versions will charge you the same international rate and may route inconsistently from mobile.

Chase Bank | +1 (713) 262-3300 | 24/7

Bank of America | +1 (315) 724-4022 | Mon-Fri 7 AM-10 PM, weekends 8 AM-5 PM

The IRS, SSA, and USCIS all publish these numbers on .gov sites — they're built for calls from overseas. Calling US banks from abroad covers the wider bank list, including the Florida and New York branches most Colombian-American customers actually deal with.

A 15-minute call to Chase from Colombia:

On Claro Móvil rack rate (no pack): $7,485 COP (~$2.00 USD)
On Movistar prepaid rack: $9,435 COP (~$2.52 USD)
On Tigo pospago: free (included in plan)
On WorldDialer: $0.60 USD (~$1,125 COP)

Same Chase. Different bill.

When to Call the US from Colombia

Colombia is on UTC-5, the same as US Eastern Standard Time. You already share US business hours. Colombia doesn't observe daylight saving — the US does — so the alignment shifts by an hour twice a year, but most months Bogotá and New York are reading the same clock.

US East Coast 9 AM-5 PM = roughly 9 AM-5 PM COT (October-March) or 8 AM-4 PM COT (US DST)
IRS opens 6 AM ET = 6 AM COT — early but workable
USCIS opens 8 AM ET = 8 AM COT — normal business hour
West Coast 9 AM-5 PM = 12 PM-8 PM COT (October-March) or 11 AM-7 PM COT (US DST)

This is the rare positive in an international-calling article. Most countries get a brutal pre-dawn window to reach US institutions. From Colombia, you call during your own workday. Schedule a Chase call for 10 AM Bogotá time and it's 10 AM in New York. Done.
