El Salvador numbering plan & how to dial
El Salvador uses an open numbering plan under country code +503. 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 El Salvador from abroad.
El Salvador has 52% internet penetration and is served by 3 major mobile networks (Tigo El Salvador, Claro El Salvador, Digicel El Salvador). VoIP is permitted and regulated by SIGET (Superintendencia General de Electricidad y Telecomunicaciones). The local currency is USD 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 +503 country code to reach El Salvador.
Keeping the national trunk "0"
If a El Salvador number is written with a leading 0 for domestic use, omit that 0 after the +503 country code when calling from abroad.
Ignoring the time difference
El Salvador runs on UTC-6. Check local hours before dialing so calls don't land outside business time.
