Cultural Tip
In France and most French‑speaking countries the universal emergency number is 112, not 911. When you are in a French‑speaking region, dial 112. However, many French speakers living in or traveling to the United States and Canada will still refer to the number as “le 911”. Using the article “le” before a telephone number is common in French (e.g., le 112, le 17). Keep your tone calm and concise when you actually make the call.
