Calling the US from abroad · 2026
US phone number for cold calling from abroad: four ways compared
Last updated September 4, 2026
The question arrives in the same words from Karachi, Lahore, Delhi, Lagos, Nairobi, Bogotá and Manila: “I have a cold calling job for a US client. How do I get a US number?” The answers on the forums are consumer number apps that suspend you the first week, or “just use Twilio” without the rule that now blocks a Twilio account opened abroad from calling the US at all. Here are the four routes with the walls stated, the wholesale cost, and the calling windows for each region.
The short answer
The route that works is for your US client to own the Twilio account. They buy a US local number for ~$1.15/month and invite you into a browser dialer; calls cost ~$0.014/min plus a browser leg, about $22 a month at 80 dials a day. An account you open from abroad can buy the number but, since 8 October 2025, cannot call +1 numbers until Twilio approves a Business Profile. There is no free US number you are allowed to cold call from.
The four routes
| Route | How you get the number | The wall | Cost | Verdict |
|---|---|---|---|---|
| 1. The US client owns the Twilio account | Client upgrades Twilio, buys a US local (~$1.15/month), connects a browser dialer, invites you by email | None for +1 calling. Client does the Business Profile once, which also unlocks A attestation on its numbers | ~$0.014/min + browser leg; ~$22/mo at 80 dials/day, billed to the client | The route that works for an agent or a small agency |
| 2. Your own Twilio account, opened abroad | Sign up, add a card, buy a US local number | No +1 calls until a Business Profile (ID + selfie) is approved; Individual profiles do not count | Same wholesale rates once approved; you carry the bill and rebill the client | Works for a registered agency that wants telephony on its own books |
| 3. A managed line from the dialer | Pick a US or Canadian area code at checkout; live in about a minute | Hard caps: 1,500 minutes and 400 dials a day per line; voice only | $49/month including the number and Pro for 3 users | A solo caller who wants a number today and no carrier console, ever |
| 4. A consumer virtual-number app | Download, pay $1–15 a month, get a number in an app | Terms bar telemarketing and auto-dialing; no list, no recordings, no team; numbers get suspended | Per-minute bundles at retail, often several times wholesale | For receiving verification codes, not for dialing a list |
Why route 2 stopped working in October 2025
Twilio's error documentation for 21216 and 13225 (“Call blocked by Twilio”) now carries a specific line: if the account was created outside the United States or Canada on or after 8 October 2025, a Business Primary Customer Profile must be created and approved before any call to a +1 number will connect, and support cannot lift the restriction by hand. The profile wants a legal business name, a physical address, a website, an authorised representative, a government ID photo and a selfie. Twilio quotes up to 48 hours for review.
For a registered agency this is one afternoon of paperwork and then the account behaves like any other. For an individual agent it is usually the end of route 2, because the profile is for businesses. That is not a loss: the US client is the party liable for the calls under US law, so the client should own the number, the recordings and the compliance record. Route 1 gives you exactly that, and you never touch a Twilio console.
The monthly bill on route 1 or 2, at wholesale
Two legs per browser call: the US leg at ~$0.014/min, billed once someone or something answers, and the browser leg at $0.004 a minute, billed from the moment you dial. Carriers round every answered call up to a whole minute, so each voicemail pickup costs a full minute even when you hang up in five seconds. For one agent at 80 dials a day, 21 days, 25% voicemail, 10% connect, three-minute talks:
| Line | Per month |
|---|---|
| US leg: 924 billed minutes (504 talk + 420 voicemail) × ~$0.014/min | $13 |
| Browser leg: 2,016 minutes incl. ~1,092 unanswered rings × $0.004 | $8 |
| One US local number | $1 |
| Telephony, one agent | $22 |
| Dialer software: free for one person to 500 calls/mo; $29 per 3-seat pack beyond | $0–$29 |
Compare the per-seat dialers agencies are told to buy: Mojo about $99–149 a licence, PhoneBurner $140–183 a user, ReadyMode from about $199, each with US minutes bundled but each before a single hour of the agent's own time. The full line-item list is in Twilio cold calling cost.
When to call: the US business day in your time zone
US law allows sales calls from 8 am to 9 pm in the prospect's local time; the productive office window is about 9 am to 4 pm. For an East Coast list (Eastern time), that window falls at these local times. Pacific-coast prospects are three hours later again.
| Where you sit | 9 am – 5 pm New York, March–November | November–March |
|---|---|---|
| Karachi / Lahore (UTC+5) | 6:00 pm – 2:00 am | 7:00 pm – 3:00 am |
| Delhi / Mumbai (UTC+5:30) | 6:30 pm – 2:30 am | 7:30 pm – 3:30 am |
| Lagos (UTC+1) | 2:00 pm – 10:00 pm | 3:00 pm – 11:00 pm |
| Nairobi (UTC+3) | 4:00 pm – 12:00 am | 5:00 pm – 1:00 am |
| Johannesburg (UTC+2) | 3:00 pm – 11:00 pm | 4:00 pm – 12:00 am |
| Bogotá / Lima (UTC-5) | 8:00 am – 4:00 pm | 9:00 am – 5:00 pm |
| Buenos Aires (UTC-3) | 10:00 am – 6:00 pm | 11:00 am – 7:00 pm |
| Manila (UTC+8) | 9:00 pm – 5:00 am | 10:00 pm – 6:00 am |
Regions that keep their own daylight saving (parts of South America, none of South Asia or West Africa) shift by an hour on their own dates; check the pair of cities you actually work between.
Caller ID, attestation and spam labels from overseas
The prospect sees the US number on the account, with its area code, whatever country the browser is in. Whether the phone shows “verified” is STIR/SHAKEN attestation, and it follows the account: a Twilio number assigned to an approved Business Profile with the SHAKEN/STIR trust product gets A attestation; a caller ID verified from another provider is capped at B. Spam labels then follow behaviour, not geography: a number dialed several hundred times a day with short calls gets flagged wherever the agent sits. Rotate numbers by volume, not by country; see how many numbers a calling team needs.
Where each route loses
- Route 1 needs a client willing to spend fifteen minutes in Twilio. Some will not. Send them the ten-minute setup guide; if that fails, route 3 exists.
- Route 2 is dead for individuals until Twilio changes the rule. Do not spend a week on appeals; the documentation says support cannot override it.
- Route 3 caps you. 1,500 minutes and 400 dials a day is plenty for one agent and not enough for three; and it is voice only.
- A bad connection beats every route. Browser calling needs a stable link; on a mobile hotspot a local SIP softphone will sound better.
US law applies to calls received in the US. The Do Not Call Registry, 8 am–9 pm local hours and caller identification rules bind the US business you call for, and that business will be the one fined. Insist on a scrubbed list before the first shift; see do you have to scrub the DNC list.
Your client's Twilio, your seat, their US number.
The client connects Twilio in ten minutes and invites you by email. You dial from the browser on their number; recordings, transcripts and AI scoring land in their account. Free for one person, $29 a month per 3 seats after that. No Twilio? A managed line is $49/month.
Start dialingQuestions people actually ask
How can I get a US phone number for cold calling if I live outside the US?
Four ways, in descending order of how well they work for cold calling. One: the US client you call for opens a Twilio account, buys a US local number for ~$1.15/month, and gives you a seat in a browser dialer; this avoids every wall. Two: you open your own Twilio account from abroad; you can buy the number, but since 8 October 2025 you cannot call +1 numbers until Twilio approves a Business Profile with ID and selfie. Three: a managed line from a dialer vendor, which gives you a US number and minutes with no carrier account at all. Four: a consumer virtual-number app, which will give you a number but will usually suspend you for telemarketing. There is no free US number that is allowed to be used for cold calling.
Is there a free USA number for cold calling?
Not one you are allowed to cold call from. Google Voice is US-only and prohibits telemarketing; TextNow-style free apps forbid commercial calling and drop numbers that go unused; trial numbers on Twilio can only call verified recipients. The cheapest legitimate US number is a Twilio local at about $1.15 a month, which is less than the cost of one lost afternoon to a suspended free account.
Why does Twilio block my calls to US numbers from my account in India or Pakistan?
Twilio applied a rule on 8 October 2025: accounts created outside the United States or Canada on or after that date cannot place calls to +1 destinations until a Business Primary Customer Profile is approved in Trust Hub. The failure shows as error 21216 or 13225, "Call blocked by Twilio", and Twilio's error documentation states support cannot remove the block manually. Submit a Business profile (legal name, address, website, authorised representative, government ID photo, selfie); Twilio quotes up to 48 hours for review. An Individual profile does not satisfy the rule.
What does it cost per month to cold call the US from abroad on your own Twilio?
Wholesale: ~$0.014/min for the US leg, about $0.004 a minute for the browser leg (which also bills ringing time), and ~$1.15/month for the number. At 80 dials a working day with a quarter reaching voicemail and one in ten reaching a person for three minutes, that is about 924 billed minutes and roughly $22 a month of telephony. Dialer software on DialSheet is free for one person up to 500 calls a month and $29 a month per 3 seats beyond that.
Will US prospects see a local number when I call from overseas?
Yes. The call is carried over the internet from your browser and enters the US phone network from the US number on the account, so caller ID shows that number and its area code. Whether it shows as "verified" depends on STIR/SHAKEN attestation, which follows the account that owns the number: a Twilio number assigned to an approved Business Profile with the SHAKEN/STIR trust product gets A attestation; a verified caller ID from another provider gets B at best. That is another reason for the US client to own the account.
Do US telemarketing laws apply to me if I am calling from another country?
Yes. The TCPA and the Telemarketing Sales Rule cover calls received in the United States wherever they originate, and enforcement lands on the US business the calls are made on behalf of. Consumer lists must be scrubbed against the National Do Not Call Registry, calls stay between 8 am and 9 pm in the prospect's time zone, and you identify yourself and the company. Business-to-business calls are exempt from the registry but not from the rest.
