What a United States number unlocks

A US phone number says almost nothing about itself. Porting has mixed landline, wireless, and internet numbers into the same area codes, and NANPA says they can no longer be told apart by area code. Services that care run a carrier lookup instead, which sorts each number as mobile, landline, or VoIP.

That lookup is where free app numbers fail. Craigslist says VoIP and international numbers are not supported for verification, and Telesign publishes tutorials on rejecting VoIP at signup because those numbers are cheap in bulk. A dedicated US number from us is a non-VoIP carrier number, so it lands in the mobile bucket.

The US is the one market where we sell every SMS tier. A one-time verification is cheaper for a single signup, and a rental fits a week or a month on one app. The dedicated number is one +1 line for accounts you keep and may need to recover.

Common use cases

Craigslist posting

Craigslist verifies posters by phone and does not support VoIP or international numbers. A dedicated +1 carrier line clears that check and stays on the account for every later repost.

One line for accounts you keep

Put the same US number on the marketplace, messaging, and developer accounts you plan to hold for years, so a recovery code sent next spring still reaches a line you control.

QA for your own signup flow

Test your app's SMS onboarding and recovery against a real US carrier number, the way customers' phones receive it, and read the parsed code from the API inside automated tests.

Phone numbers for AI agents in United States

AI agents that handle logins and account recovery for your team stall at SMS verification checkpoints. Platforms reject VoIP numbers outright, and shared OTP pools run dry mid-task.

A dedicated non-VoIP number receives OTPs over the VoidMob API, so after a one-time key setup the agent reads its own codes. The number stays assigned to your account across sessions, with no shared pool to compete for.

A USA number works best when the login comes from a USA IP too. A mobile proxy on a local carrier keeps the number and the connection telling the same story.

Frequently Asked Questions

Common questions about a dedicated United States number.

Can I get a free US number for SMS verification?
Free numbers exist, but they are public: every code sent to a receive-SMS website can be read by anyone who opens the page, and most of those numbers are VoIP ranges that carrier lookups flag. A dedicated number is private to your account and sits on a carrier range.
Is +1 only for US numbers?
No. +1 is the North American Numbering Plan code, shared by the US, Canada, and several Caribbean countries. The three-digit area code after it is what places a number in the US.
Why does Google Voice fail verification when a carrier number works?
Google Voice is a non-fixed VoIP number, the category Twilio's documentation uses it to illustrate, and services that block VoIP read that category from carrier data rather than from the digits. A carrier number never falls into that bucket.
Should I buy a one-time code or a dedicated US number?
For a single signup you will never need to verify again, a one-time code is cheaper, and it refunds in full if nothing arrives within 15 minutes. If the account matters later for logins, recovery, or a second service, a dedicated number keeps the same +1 line on it for as long as you renew.
Can I choose the area code?
No. Numbers are assigned automatically, so you choose the country but not the area code or state. Because Americans keep their numbers when they move or switch carriers, an area code no longer says much about where a subscriber lives anyway.
Is the number only mine, and how long do I keep it?
Yes: it is assigned to your account alone and billed monthly, and with auto-renew on it stays yours, while switching auto-renew off lets it lapse when the paid month ends.
Do I need ID, and where do the codes show up?
No ID to sign up or to pay with crypto. You sign up with a crypto wallet or an email, pay from a crypto-funded balance, and read each code on the number's page in the dashboard or over the API and our MCP server.
