How to Use the + 809, 829, and 849 Country Code: A Guide for SMBs and Startups

Whether you’re managing logistics in Santo Domingo or collaborating with a customer service partner in Santiago, formatting Dominican Republic phone numbers correctly is essential for smooth international communication.

This guide walks through everything SMBs and startups need to know about the 809, 829, and 849 codes, how they relate to the Dominican Republic, and how DialLink’s cloud phone system simplifies international calling.

What Is the 809, 829, and 849 Country Code?

These three codes — 809, 829, and 849 — are area codes used within the Dominican Republic, which operates under the +1 country code as part of the North American Numbering Plan (NANP), just like the United States and Canada.

Here’s how it breaks down:

• Country Code: +1
• Area Codes for Dominican Republic: 809, 829, 849
• Number Format: +1 809 XXX XXXX (or 829 / 849)

These codes are interchangeable and cover the entire country. The use of multiple codes allows for better number availability, but they function the same way from a formatting and dialing perspective.

Common Pitfalls in International Number Formatting

Improper formatting of Dominican Republic phone numbers can lead to failed connections or errors in CRM platforms. Here are the most frequent issues:

• Omitting the country code (+1): This is required, even though the number may look like a US number.
• Forgetting to identify the correct area code (809 / 829 / 849): All three are valid and active; assuming only 809 is correct can cause confusion.
• Inconsistent CRM formatting: Always use E.164 format (e.g., +18091234567) for contact records across platforms.
• Incorrectly assuming these numbers are US-based: Because the +1 code covers multiple countries, ensure your system recognizes them as Dominican Republic numbers.

By standardizing number formatting, you reduce delivery issues and enhance automation and reporting accuracy across systems.

Common Dominican Republic Number Format Examples

Note: Toll-free numbers (e.g., 1-800) may not be accessible from outside the Dominican Republic and could incur charges when dialed internationally.

How to Read and Format Dominican Republic Numbers

Dominican phone numbers follow the same structure as US and Canadian numbers, thanks to the NANP system. They’re composed of 10 digits after the country code, divided into:

• Area Code: 809 / 829 / 849
• Local Number: 7 digits (XXX XXXX)

Format Variations

• International Format (E.164): +1 829 123 4567 — recommended for VoIP, CRMs, and standardized databases
• Local Format (within the DR): 829-123-4567
• NANP Long-Distance Format (from the US or Canada): 1-829-123-4567
• International Dialing Format (from outside NANP): 00 1 849 123 4567 — for regions using “00” as their exit code

Best Practices for SMBs

• Save all phone numbers in full international format: +1 849 XXX XXXX
• Recognize that 809, 829, and 849 are interchangeable Dominican Republic area codes
• Standardize phone numbers in your CRM and phone systems using E.164 formatting
• Don’t assume +1 always means a US number, validate with area code logic for the DR
• Double-check toll-free number accessibility when providing support lines

These practices help ensure your calls reach the right people and your systems function smoothly across regions.
