Dominican Republic numbering plan & how to dial
Dominican Republic uses an open numbering plan under country code +1-809. After the country code, a 3-digit area or mobile prefix is followed by a 7-digit subscriber number, giving a 10-digit national number. Domestic numbers are often written with a leading trunk "0" that is omitted when dialing Dominican Republic from abroad.
Dominican Republic has 70% internet penetration and is served by 3 major mobile networks (Claro Dominican Republic, Altice Dominican Republic, Viva Dominican Republic). VoIP is permitted and regulated by INDOTEL (Instituto Dominicano de las Telecomunicaciones). The local currency is DOP and the primary language is Spanish, which shape IVR prompts, SMS content, and business-hours handling.
Numbering across the Americas mixes the North American Numbering Plan (+1) with national E.164 plans, so mobile and fixed-line prefixes vary from country to country.
Skipping the exit code
From the US you must dial 011 before the +1-809 country code to reach Dominican Republic.
Keeping the national trunk "0"
Dominican Republic numbers often show a domestic leading 0 — drop it once you've dialed the +1-809 country code from outside the country.
Ignoring the time difference
UTC-4 governs local business hours in Dominican Republic; confirm the time there before placing the call.

FAQ
Calling Dominican Republic — frequently asked questions
The US exit code is 011 for any international call, including to Dominican Republic. It comes right before the +1-809 country code, and Twiching adds both automatically when you dial from the app, so you only need to enter the local number.
Dominican Republic runs on UTC-4. Knowing this helps schedule calls and support hours so they land during the local business day rather than the middle of the night for the person picking up.
Since Dominican Republic is on UTC-4, plan calls around local business hours there rather than US hours — off-hours calls tend to go unanswered. It's worth checking the current time difference before a first outreach call, since it can shift with daylight saving in either country.
Calling Dominican Republic means dialing 011, then +1-809, instead of the domestic US format — plus accounting for the UTC-4 time difference. Domestic US calls skip both the exit code and the international country code entirely.
The subscriber portion of a Dominican Republic number is 7 digits, after the country code and area/mobile prefix. That's the part that identifies the specific line once the call has been routed to the right network.
Yes — Dominican Republic numbers often carry a domestic leading 0 that should be dropped once you've dialed the +1-809 country code from abroad. Keeping that 0 in is one of the most common reasons an international call to Dominican Republic fails to connect.
