Area Code 22 – Pichincha

Geographic Significance and Coverage

Area code 22 is the National Destination Code (NDC) for the province of Pichincha in Ecuador, with the capital city Quito as its primary hub. This code covers the Metropolitan District of Quito and surrounding cantons, including Cayambe, Mejía, Pedro Moncayo, Pedro Vicente Maldonado, Puerto Quito, San Miguel de Los Bancos, and Rumiñahui. As a geographic code, it is tied to the PSTN infrastructure of the region, serving both fixed-line residential and business subscribers.

Dialing Formats and Procedures

When calling a fixed-line number in Pichincha from within Ecuador, dial the trunk prefix 0, followed by the area code 22 and the 7-digit subscriber number. The national format is 0 22 XXX XXXX (or 02 2XXX XXXX when written with the trunk prefix). For international callers, dial the Ecuador country code +593, then the area code 22 (without the leading 0), followed by the 7-digit number: +593 22 XXX XXXX.

For example, a local call within Quito to a number like 2 234 5678 would be dialed as 02 2234 5678 from elsewhere in Ecuador, and as +593 22 234 5678 from abroad. Note that the area code is an integral part of the national numbering plan; even local calls within Quito require the full national number (including area code) when dialed from mobile phones.

Overlay and Numbering Considerations

Currently, there is no overlay code for Pichincha; the area code 22 remains exclusive to the province. However, due to growing demand, the telecom regulator (ARCOTEL) has implemented number conservation measures. Subscriber numbers are 7 digits long, and the total length of a national significant number (NSN) is 8 digits (area code + subscriber number). This structure is consistent with ITU-T E.164 recommendations.

Practical Information for Callers

• Local callers: When dialing from a fixed line within Pichincha, you may omit the area code if your service provider supports local dialing, but it is safer to include the full number to avoid misroutes.
• National callers: Always include the trunk prefix 0 before the area code when calling from other provinces.
• International callers: Replace the trunk prefix with the country code +593 and drop the leading 0 of the area code.
• Mobile calls: Calls from mobile phones to fixed lines in Pichincha require the full national number (e.g., 02 2234 5678).

Understanding these dialing rules ensures seamless connectivity with businesses and residents in Ecuador's capital region.
