Get a 548 Area Code Local Virtual Number for London, Ontario

The 548 area code is one of the newer telephone area codes introduced in Canada. As part of the North American Numbering Plan (NANP), it serves the southwestern region of Ontario, including major cities such as London, Windsor, Kitchener, Guelph, and Sarnia.

To meet the increasing demand for phone numbers, 548 was introduced as an overlay to the existing 226 and 519 area codes. Ontario operates within the Eastern Time Zone (ET) — UTC-5 during standard time and UTC-4 during daylight saving time.

The 548 area code is located in the southwestern region of Ontario, Canada. It was introduced as an overlay to the existing 226 and 519 area codes and serves the same geographic area. Major cities within this coverage zone include London, Windsor, Kitchener, Guelph, Sarnia, and Stratford.

Because it’s an overlay, the 548 area code does not correspond to a specific city but is assigned across the region alongside its overlay counterparts. As a result, 10-digit dialing (area code + phone number) is mandatory for all local calls.

A virtual number in the 548 area code helps your business build local credibility in Ontario’s growing markets. When paired with features like an auto attendant, it enhances your professional image by routing calls efficiently and delivering a streamlined caller experience—no physical office required.

The 548 area code was officially introduced in June 2016 as an overlay to the existing 226 and 519 area codes in southwestern Ontario. The original 519 area code had served the region since 1953, with 226 added in 2006 to accommodate increasing demand.

As mobile usage expanded and new businesses emerged, the pool within the 226/519 region began to run low. To prevent number exhaustion and support ongoing growth, the VoIp Laws and regulations in Canada approved the addition of 548.

Overlays like 548 allow new phone numbers to be introduced without changing existing ones, ensuring a seamless transition for residents and businesses. Today, 548 is widely used across cities like London, Kitchener, and Windsor, playing a key role in maintaining Ontario’s connectivity while supporting long-term economic and digital development.
