Bulk area code to state lookup: add the state or province and time zone to a list of US and Canadian numbers
In short: Paste numbers or a CSV and get the area code, state or province, country and time zone added to every +1 number. Limit: An area code shows where a number was issued, not where its owner lives now.
Paste a list of US and Canadian phone numbers or upload a CSV, and each valid +1 number gets its area code, the state or province it was issued in, the country and the time zone, from the NANPA area code table. Numbers outside +1, and numbers that fail the format check, are marked and left blank.
Price: this tool is free. Live line type and carrier lookups come with Pro + Phone at $49.99/mo; email checking is from $9/mo. See pricing
Pick United States or Canada for numbers written without a +1.
Sample result
415 is California, 212 is New York and 416 is Ontario, Canada; a UK number is marked not +1.

- Download the file with its area code columns.
- Upload or paste it at /verify. Every address gets a live mailbox check, and the first 100 email checks are free with a Google sign-in, no card.
How do I look up the state for many area codes at once?
- Pick United States or Canada as the default country for numbers written without a +1.
- Paste the list or upload a CSV; the phone column is found for you.
- Press the button and read the new columns: area code, state or province, country and time zone.
- Download the CSV with the original columns plus the four new ones.
Example
- You enter
- Five numbers read as US numbers: (415) 555-0132, 212-555-0100, (416) 555-0134, +44 20 7946 0958 and 555-1234.
- You get
- 3 area codes placed: 415 is California (America/Los_Angeles), 212 is New York (America/New_York) and 416 is Ontario, Canada (America/Toronto). The UK number is marked not +1 and 555-1234 is marked not valid.
- Limits
- Runs in your browser; nothing is uploaded. An area code shows where a number was issued, not where its owner lives now.
What does each new column mean?
The area code is the first three digits after the +1. The state or province is where NANPA, the North American numbering administrator, says that code was issued. The time zone comes from the same table; where a code covers two zones, both are shown.
Overlay codes, which share a region with an older code, are placed in the same state as the code they overlay. Numbers that are not valid +1 numbers get blank columns and a note in the check column.
Is the state where the person is?
Not always. An area code says where a number was first issued. Mobile numbers keep their code when the owner moves, and many people live far from the place their number came from. For deciding when to call, the time zone is a good start; for an address, it is not.
To split a list by time zone for a calling window, use the lead list time zone splitter, and check the hours with the TCPA calling hours checker.
How is this different from the area code lookup?
The area code lookup answers for one code at a time and lists cities and overlays. This tool takes a whole list, reads the area code out of every number however it is written, and adds the answer to each row.
Numbers are read with the libphonenumber data first, so (415) 555-0132, 415.555.0132 and +1 415 555 0132 all give 415.
Who uses this tool, and for what?
- Sales teams
- Sort a US lead list by state or time zone before a call block.
- Marketers
- Group SMS recipients by region to match a local offer or send time.
- Operations
- Find which states a customer export covers, for licensing or tax checks.
What can’t this tool tell you?
- An area code shows where a number was issued, not where its owner lives now.
- Where a code covers two time zones, the tool shows both; it cannot say which applies to a person.
- Only +1 numbers get a place; other countries are marked and left blank.
- The NANPA file changes as codes are added; very new codes may be missing until the table is updated.
Common questions
- Does it work for Canadian numbers?
- Yes. Canadian area codes are in the same table and show the province and country.
- What about Caribbean numbers under +1?
- They are in the table and show the territory or country, such as Jamaica, as the place.
- Why is a number's state blank?
- It is not a valid +1 number, or it is a number from another country code. The check column says which.
- Does it use a carrier or phone-company lookup?
- No. It uses the public NANPA area code table and the numbering plan, never carrier data.
- Does this show a number is active?
- No. It reads the number against its country's numbering plan, or edits text. Nothing here contacts a phone network, so it cannot say a line is connected, who holds it, or that anyone will answer.
- Is my list uploaded?
- No. It is read in your browser and goes nowhere, so a customer list stays on your device.
Well formatted is not the same as reachable.
This tool fixes how numbers are written. It cannot tell you whether a line is mobile, landline or VoIP, or which carrier holds it. That takes a live carrier lookup, which is what Pro + Phone ($49.99/mo) adds.
- Upload a CSV up to 100,000 rows with an email or phone column
- 5,000 live carrier lookups a month: carrier name and real line type
- Emails in the same file get a real SMTP mailbox check
