TL;DR. From a UAE landline, dial 00 1 800 555 0142; from a mobile, +1 800 555 0142. Many US toll-free lines refuse callers outside North America. Internet calling apps are a weaker fallback here than elsewhere, because the UAE regulator restricts VoIP that is not licensed or approved.
You can dial it, but many lines will not answer. The US company pays for toll-free calls and picks where they may come from: the US only, the US and Canada, or the US and the Caribbean [5]. The Gulf is never on that list. AT&T says that from outside North America, toll-free numbers usually don't connect or aren't free [6].
So a call from Dubai or Abu Dhabi on a UAE mobile or landline may connect and be billed as an international call, may play a recording, or may fail with no message. Your best first move is the company's number for overseas callers, dialed from a regular UAE phone.
How do you dial a US 1-800 number from the UAE?
Dial 00, then the US country code 1, then the ten-digit number. The UAE's exit code is 00 [1], and the US shares country code 1 with Canada [1]. On a mobile, type +1 and the number: the plus sign replaces 00. Keep all ten digits after the 1 [6]. The same pattern serves every US toll-free code.
Same pattern for 833, 844, 855, 866, 877 and 888 [7].
If the number has letters, such as 1-800-FLOWERS, convert them on the 1-800 letters page.
Can you use calling apps in the UAE to reach a 1-800 number?
Be careful. The UAE regulator, TDRA, treats VoIP as a telecom service. Its FAQ says apps not provided by a licensee, built with one or approved by TDRA are very likely illegal to use for voice calls, and users may be liable [2]. Licensees must block unlicensed VoIP [2]. This is not legal advice; check TDRA's current guidance.
That changes the ranking below for UAE readers. The scores are the same as for every country, but here the internet-based options carry an extra question mark. Viber itself lists the UAE among countries where Viber Out may have connectivity issues [3]. I found no TDRA statement approving TwinPhone, Viber Out or Google Voice for calls.
So in the UAE my first choice is the company's overseas number, dialed over a regular UAE line. An app is only an option if you are sure it is permitted where you are.
Which way to call a US toll-free number from the UAE works best?
The ranking below uses one published method for every country, and I did not change the scores for the UAE. Read it with the TDRA caveat above: the internet-based routes may not be permitted here, while the company's own overseas number, dialed over a regular phone line, raises no such question. A UAE SIM dialing the 1-800 number directly scores low on reach.

It is not free. If the call connects through your UAE operator, you pay your plan's rate for an international call to the US. US visitors on roaming pay roaming rates: T-Mobile charges AED 1.84 a minute for cellular calls in its covered destinations [19], and Google Fi AED 0.73 on two plans [36]. A collect call placed through the operator costs you nothing where the company accepts one.

TwinPhone lists AED 0.073 a minute [12] and bills nothing for failed calls [12], but some US lines accept only certain states [14], and the TDRA rules above apply to any internet calling service. I read its page on dialing the US from the UAE; it does not change what TDRA says. I left Viber Out out of this table because of its own UAE warning.
What should you do if the 1-800 number won't connect from the UAE?
Find the company's number for overseas callers and dial it from your UAE phone. Many large US banks and agencies publish a regular +1 number or a collect line, and both work over the normal phone network. If none exists, ask for chat, email or a callback. That keeps you clear of the VoIP question entirely.
Search the company's contact page for "outside the US". The IRS lists +1 267 941 1000[4].
Ask for a collect call where offered: Bank of America lists +1 315 724 4022[8], placed through the local operator [8].
Look for a country access code. Wells Fargo lists international toll-free access codes by country [46].
Use chat, secure messaging or a callback request if the company offers one.

Can you use an app for emergency calls in the UAE?
No. In the UAE, call 999 for the police and 998 for an ambulance, from a regular phone; both work anywhere in the country [49]. TwinPhone cannot dial emergency numbers [14], and personal Google Voice accounts cannot either [31]. A US 1-800 number is never an emergency route. More countries are on the 1-800 from abroad hub; the basics are on the home page.

Viber lists the UAE among countries where Viber Out may have connectivity issues [3]. Do not count on it for an important call.
