Costa Rica numbering plan & how to dial
Costa Rica uses an open numbering plan under country code +506. After the country code, a 2-digit area or mobile prefix is followed by a 8-digit subscriber number, giving a 10-digit national number. Domestic numbers are often written with a leading trunk "0" that is omitted when dialing Costa Rica from abroad.
Costa Rica has 74% internet penetration and is served by 3 major mobile networks (ICE (Instituto Costarricense de Electricidad), Claro Costa Rica, Movistar Costa Rica). VoIP is permitted and regulated by SUTEL (Superintendencia de Telecomunicaciones). The local currency is CRC 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 +506 country code to reach Costa Rica.
Keeping the national trunk "0"
Costa Rica numbers often show a domestic leading 0 — drop it once you've dialed the +506 country code from outside the country.
Ignoring the time difference
UTC-6 governs local business hours in Costa Rica; confirm the time there before placing the call.

FAQ
Calling Costa Rica — frequently asked questions
Yes, where locally supported — a single Twiching Costa Rica number can handle both voice calls and SMS. That avoids the overhead of provisioning and managing two separate numbers for one customer-facing line.
A recognisable +506 number tends to get answered more often than an unfamiliar international one — that's the main reason to present local caller ID in Costa Rica. Unknown foreign numbers are frequently screened or ignored, which can quietly suppress answer rates on outbound sales and support calls.
Yes — Costa Rica is one of 191+ countries in Twiching's directory, with virtual numbers, SIP termination, and Tier-1 routing available. It's part of the same platform used to manage numbers across every other country in the directory.
Where locally supported, yes — Twiching's Costa Rica numbers can send and receive SMS in addition to voice calls. That makes a single number usable for both two-way conversations and outbound notifications.
SUTEL (Superintendencia de Telecomunicaciones) is the regulator for Costa Rica. Twiching routes calls in line with its rules for compliant, licensed termination, rather than relying on unlicensed grey routes that can be blocked or degraded.
Calling Costa Rica means dialing 011, then +506, instead of the domestic US format — plus accounting for the UTC-6 time difference. Domestic US calls skip both the exit code and the international country code entirely.
