Is +1 the same as 011 when calling the US from Mexico?

Not quite. 011 is the international exit code used from inside the United States to dial out, not into. From Mexico, you dial 00 to exit (or just use +1 on a mobile, which substitutes the right code automatically). The US country code is 1. So from a Mexican mobile, +1-212-555-1234 works. From a Mexican landline, dial 00-1-212-555-1234. Using 011 from a Mexican phone won't connect because that code only means "exit" inside the US dialing plan.

Is it ever actually free to call the US from Mexico?

Yes, if both sides use an app like WhatsApp, FaceTime, Signal, or Telegram. Those are app-to-app calls over the internet and cost nothing beyond your data plan. Google Voice gives US-account holders free calls to US and Canadian numbers, including from Mexico, but it requires a Google account verified with a US phone number first. Calls to US landlines or non-app US mobiles always cost something through a carrier, VoIP service, or pay-as-you-go option like World Dialer at $0.04 a minute.

Does the 880/881 toll-free workaround code still work in 2026?

Sometimes, but it's less reliable than it used to be. The 880-prefix service (PaidToll, formerly run by AT&T) routes international callers to US toll-free numbers and bills your originating carrier at full international rates. Some Mexican carriers have stopped routing these codes, especially Telcel prepaid plans. The conversion (1-800 becomes 001-880, 1-888 becomes 001-881) works on AT&T Mexico postpaid and Movistar but fails on others. Finding the direct-dial number on the company's "International Contact" page is the more reliable fix.

Will my Telcel Amigo prepaid plan let me call US numbers at all?

Yes, but only if your balance covers it and the destination isn't blocked. Telcel Amigo prepaid charges around 3-5 pesos per minute (roughly $0.18-$0.30) for calls to US numbers, deducted from your saldo. Some prepaid promotions advertise "Estados Unidos incluido," but those typically only cover regular US landlines, not toll-free numbers. Top up at least 50 pesos before trying a long call. If you're getting "saldo insuficiente" messages, the rate per minute may have changed or the destination isn't part of your included countries.

When does Mexico's time difference with the US change because of DST?

Twice a year. Mexico dropped national Daylight Saving Time in 2022, but the US still observes it. Clocks in the US shift forward on the second Sunday in March and back on the first Sunday in November. From mid-March through early November, Mexico City is 2 hours behind US Eastern Time instead of 1. Border cities along the US-Mexico line (Tijuana, Ciudad Juarez, Reynosa) are an exception and still follow US DST. Always double-check before calling government lines with narrow hours like Social Security at +1 (410) 965-7306.

Call US from Mexico: Landline Numbers Made Easy

Calling the US from Mexico costs $1-3/minute on most prepaid plans. That's $30 for a 10-minute call to your bank. Some Mexican carriers include US calling in their plans - if yours doesn't, here's how to dial correctly and pay $0.04/minute instead.

Why Calling the US from Mexico Gets Expensive

Mexican carriers charge $1-3/minute for international calls on basic plans. Telcel, AT&T Mexico, and Movistar all offer plans that include US calling, but you'll pay $30-60/month for them. If you're on prepaid or a basic postpaid plan, those "included" minutes probably aren't included for you.

The fine print matters. "North America calling" might mean Canada and the US - or it might mean limits, peak-hour charges, or landline-only restrictions. And US toll-free numbers? Those don't work at all from Mexico. More on that in a moment.

For occasional callers who don't want a pricier plan, browser-based services like World Dialer charge $0.04/minute with no subscription required.

How to Dial the US from Mexico

From a Mexican mobile, dial +1 followed by the 10-digit US number. That's it.

Example: +1 (212) 555-1234

If you're calling from a Mexican landline, dial 00 1 then the number:

Example: 00 1 212 555 1234

Mexico simplified its dialing rules in August 2019. The old "dial 001 for international" from mobiles is gone. The confusing "add 1 after the country code for US cell phones" rule is gone. Now it's just +1 plus the number.

If you're following a guide that mentions dialing 044 or 045, or adding extra digits for mobile numbers - that guide is outdated. Ignore it.

The Toll-Free Problem (and Workaround)

US 1-800 numbers don't work from Mexico. Neither do 888, 877, 866, or 855 numbers. Your call either won't connect or you'll get a "number not in service" message.

There's a workaround. Replace the toll-free prefix with a conversion code:

US Prefix	Dial from Mexico
1-800	001-880 + number
1-888	001-881 + number
1-877	001-882 + number
1-866	001-883 + number
1-855	001-884 + number

So 1-800-555-1234 becomes 001-880-555-1234.

But here's the catch: These converted calls aren't free. You're paying full international rates. If you're calling a company regularly, find their non-toll-free number instead. Most US banks and government agencies have international lines specifically for overseas callers.

US Numbers You'll Actually Need

Here are the international (non-toll-free) numbers for US institutions. Save these - they'll work from any Mexican phone.

Institution	International Number	Hours (US Eastern)
Chase Bank	+1 (713) 262-3300	24/7
Bank of America	+1 (315) 724-4022	Mon-Fri 8am-11pm
IRS	+1 (267) 941-1000	Mon-Fri 6am-11pm
Social Security	+1 (410) 965-7306	Mon-Fri 8am-3pm

These are direct lines for international callers. They're not toll-free, which means they actually work from Mexico. For Chase, that +1 (713) 262-3300 number is specifically set up for fraud and identity theft concerns - useful if your card gets flagged while traveling.

Your Calling Options Compared

Three options. Two cost money every month. One doesn't. Here's what each actually costs:

Method	Cost	Setup	Best For
Carrier plan with US calling	$30-60/month	Plan upgrade	Frequent callers
VoIP subscription (Skype, etc.)	$5-15/month	App download	Regular callers
Browser-based (World Dialer)	$0.04/minute	None	Occasional callers

If you're calling the US daily, upgrade your carrier plan. The math works out.

If you need a call once a month, a VoIP subscription is overkill. You're paying $60-180/year for maybe ten calls. That's the subscription tax at work.

World Dialer charges $0.04/minute to US landlines. No subscription required, no app download - it runs in your browser. A 10-minute call to your bank costs $0.40. You pay for the call, not for access to the possibility of making calls.

Time Zone Tips

Mexico City is 1 hour behind US Eastern time. Cancun (Quintana Roo) is the same as Eastern.

To reach US East Coast business hours (9am-5pm ET), call between 8am-4pm from Mexico City. For West Coast businesses, you have until 6pm local time.

One catch: Mexico dropped Daylight Saving Time in 2022. The US didn't. So the time difference shifts by an hour twice a year when the US changes clocks. If you're calling in March or November, double-check the current difference.

The IRS international line is open 6am-11pm Eastern - that's 5am-10pm in Mexico City. Social Security has tighter hours: 8am-3pm Eastern only. Plan your call accordingly.
