Is this a US number? +1 checker for the US, Canada and the Caribbean

In short: Reads each +1 number's area code against NANPA's database: US state, US territory, Canada, or another +1 country such as Jamaica or the Dominican Republic. US-only and non-US CSVs. Limit: Numbering plan only: the area code says where a number was issued, not where the person is or whether the line is live.

A +1 number is a US number only if its area code belongs to a US state, DC or a US territory. +1 is shared by 25 countries and territories in the North American Numbering Plan, so 876 is Jamaica and 204 is Canada. Paste numbers or a CSV to see each one's country from NANPA's area code database.

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

How do I check whether phone numbers are US numbers?

  1. Paste numbers, one per line, or upload a CSV; the phone column is found automatically. Ten-digit numbers without a code are read as +1.
  2. Press Check the +1 numbers. Each row gets its area code, the state, province or country NANPA records for it, and whether it's a US number.
  3. Look at the counts: US states, US territories, Canada, other +1 countries, other country codes, toll-free or service codes, and area codes not in service.
  4. Download the full report, the US numbers only, or everything that isn't a US number.

Example

You enter
(415) 555-0132, +1 876 555 0147, 1-204-555-0199, (787) 555-0110, +44 20 7946 0958 and (999) 555-0100.
You get
(415) 555-0132 is a US number (California); (787) 555-0110 is a US territory (Puerto Rico); 1-204-555-0199 is Canada (Manitoba); +1 876 555 0147 is another +1 country, Jamaica; the UK number has another country code; area code 999 isn't in service. Download US numbers only or the rest.

How do I know if a +1 number is from the US?

Look at the area code, the three digits after +1. The North American Numbering Plan, run by the North American Numbering Plan Administrator (NANPA), covers the United States and its territories, Canada, Bermuda and 17 Caribbean countries and territories, all on country code +1. Each area code belongs to exactly one of them: 212 is New York, 416 is Ontario, 876 is Jamaica, 809, 829 and 849 are the Dominican Republic.

This checker reads every area code against NANPA's area code database, so it also catches reserved test numbers such as 555-01xx that some libraries leave without a country. Puerto Rico, the US Virgin Islands, Guam, the Northern Mariana Islands and American Samoa are US territories and count as US numbers; they're shown separately so you can treat them differently if you need to.

Which area codes are not in the US?

Canada has its own area codes (204, 226, 236, 249, 250, 289, 306, 343, 365, 403, 416, 418 and more), and 18 other countries and territories have one or more: Anguilla 264, Antigua and Barbuda 268, Bahamas 242, Barbados 246, Bermuda 441, British Virgin Islands 284, Cayman Islands 345, Dominica 767, Dominican Republic 809/829/849, Grenada 473, Jamaica 876/658, Montserrat 664, Saint Kitts and Nevis 869, Saint Lucia 758, Saint Vincent and the Grenadines 784, Sint Maarten 721, Trinidad and Tobago 868, and Turks and Caicos 649.

They are dialled exactly like US numbers, 1 plus ten digits, which is why they slip into US lists. Calls and texts to them are international: carriers and SMS platforms price them by country, and US rules such as the TCPA aren't the rules that apply there. The FTC has warned that some of these codes are used in one-ring callback scams; see the one-ring scam checker.

Does a US area code mean the person is in the US?

No. The area code says where the number was issued, not where the phone is. People keep their numbers when they move, numbers are ported between carriers, and VoIP numbers can be bought in any area code from anywhere. A US area code means the number belongs to the US numbering plan; it doesn't prove the line is live or who holds it.

That needs a live carrier lookup, which this page doesn't do: nothing here contacts a network, and the result comes from numbering-plan ranges only.

Who uses this tool, and for what?

SMS teams
Pull Caribbean and Canadian +1 numbers out of a US audience before a send, so international rates and other countries' rules don't catch you out.
Sales teams
Keep a US dialing list to US numbers, and route Canadian leads to the team that covers Canada.
Fraud and signup teams
Flag signups whose +1 number is outside the US when you only serve US customers.
Data teams
Fill a country column for a +1 list without guessing from the + code alone.

What can’t this tool tell you?

  • Numbering plan only: the area code says where a number was issued, not where the person is or whether the line is live.
  • Ten-digit numbers without a code are read as +1; a foreign number written without its code will come back as not valid.
  • US territories count as US numbers; split them out with the report's place column if you need to.
  • Up to 500 rows a run without an account and 25,000 when signed in with Google.

Common questions

Is +1 always the United States?
No. +1 is the country code for the whole North American Numbering Plan: the US and its territories, Canada, Bermuda and 17 Caribbean countries and territories. The area code after +1 decides which.
Is area code 876 in the US?
No. 876 (and 658) is Jamaica. It is dialled like a US number, 1-876 and seven digits, but a call to it is an international call.
Is a Canadian number a US number?
No. Canada shares +1 and the ten-digit format with the US but has its own area codes, such as 416 and 604. Many US plans include calls to Canada, but it's a different country.
Are Puerto Rico numbers US numbers?
Yes. Puerto Rico (787, 939), the US Virgin Islands (340), Guam (671), the Northern Mariana Islands (670) and American Samoa (684) are US territories in the US numbering plan.
Can you tell if a number is a cell phone from the area code?
No. In the US and Canada mobiles and landlines share area codes. The landline or mobile checker explains what the numbering plan can and can't say; only a carrier lookup gives the line type.

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
