Postal Codes in Newfoundland and Labrador
Newfoundland and Labrador's postal codes cover Canada's easternmost province, a rugged, storm-battered landscape of fishing villages, fjords, and the vast, sparsely populated Labrador wilderness to the north. With around 540,000 residents, the province has one of the smallest populations in the country, and St. John's, the capital, dominates the province's economy and population by a wide margin.
How Postal Codes Are Organized Across the Province
Newfoundland and Labrador's postal codes use the leading letter "A" under Canada's national alphanumeric system. St. John's carries codes starting with A1, Corner Brook, on the island's west coast, uses codes starting with A2, and the mainland Labrador region carries codes starting with A0.
Newfoundland and Labrador's Major Cities by Population
The chart below shows just how dominant St. John's is within the province's overall population, dwarfing every other town by a wide margin.
St. John's postal codes cover the province's capital and largest city, one of the oldest European-settled cities in North America, with a colorful downtown known for its "Jellybean Row" of brightly painted houses along the harbor. Corner Brook, on the island's west coast, serves as the main regional hub for western Newfoundland, historically tied to the pulp and paper industry.

Outport Communities and the Fishing Industry
Newfoundland's coastline is dotted with small "outport" fishing communities, many accessible only by boat or a single winding road, that have shaped the province's cultural identity for centuries. The collapse of the cod fishery in the early 1990s hit these communities especially hard, and postal codes in this region often cover towns that have seen sustained population decline since, even as offshore oil development has brought new economic activity to parts of the province.
Labrador and the Mainland
Labrador, the mainland portion of the province separated from the island of Newfoundland by the Strait of Belle Isle, is a vast, sparsely populated wilderness region bordering Quebec. Labrador City and Churchill Falls anchor a regional economy built around iron ore mining and hydroelectric power, quite different from the fishing-based economy found on the island portion of the province.
Why Postal Codes Matter Beyond Mail
In Newfoundland and Labrador, postal codes carry particular significance for the offshore oil industry, centered around St. John's, which relies on postal-code-level data for workforce and logistics coordination. Mining operations in Labrador use postal codes to manage remote workforce housing and shipping logistics. And with many small outport communities facing ongoing population decline, postal-level population data has become an important tool for provincial planning and resource allocation.
