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 $0.02/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 $0.02/minute with no subscription.

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If you're following a guide that mentions dialing 044 or 045, or adding extra digits for mobile numbers - that guide is outdated.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)	$0.02/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 $0.02/minute to US landlines. No subscription, no app download - it runs in your browser. A 10-minute call to your bank costs $0.20. 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.
