About this tool
Every US state and Canadian province has its own telephone area codes. Looking up which code a region uses — or reversing a code to find its location — is annoying to do from scattered references. This tool collects US and Canadian area codes into one searchable list.
Enter an area code to reverse-search its region (212 → New York, 310 → Los Angeles), or browse all codes for a state/province. It's ideal for phone-field testing, overseas operations, or simply figuring out where a number is from.
Common use cases
- Generate test phone numbers whose area code matches the region, avoiding obviously fake numbers
- Reverse-search an unknown area code to find its state/city
- Browse area codes per state for regional testing
- Determine location from a phone/address in customer service, logistics or e-commerce
FAQ
- Are these real area codes?
Yes. Codes map to real state/city allocations (212=New York, 310=Los Angeles, 213=California), suitable for region identification.
- Can I reverse-search?
Yes. Both 'enter code → find region' and 'browse all codes by state/province' are supported.
- Is Canada included?
Yes, along with the US states, area codes for Canadian provinces are covered too.
