In short
You need a US number when the form accepts only +1 or the service works only with American numbers. Choose your service and the United States in @HushNumBot or on the website, enter the number as +1 and 10 digits and wait for the code in your order. If no SMS arrives within 15 minutes, the money returns to your balance.
People look for an American number when a service targets the US, when the form has +1 fixed, or when they test how an app behaves for American users. In every other case, choose the country by stock and price. A US number is not "better" than others; it simply fits a particular form.
When you really need a US number
- the sign-up form does not let you change the country and shows only +1;
- the service or app is available only to American numbers;
- you test sign-up, messaging or onboarding for users in the US;
- the account is already tied to an American number and the service asks you to confirm it again.
How to enter an American number
A US number is the country code +1 and 10 digits: a three-digit area code and a seven-digit subscriber number. If the form has a country picker, choose United States (+1) and paste the 10 digits without the leading 1. If there is one field, enter the whole number: +1 and 10 digits.
Canada and some Caribbean countries also use +1, so some forms detect the country by area code and may show a Canadian flag. That is not an order mistake: you chose the United States, and the number is American.
Why American sites sometimes reject a number
Many US services check the line type: mobile, landline or internet telephony. Some do not send codes to numbers their database considers virtual. Another reason is frequent attempts: after many code requests in a row, the form stops sending SMS for a while.
- the form shows an error before sending the code: try another number, or another country if the form allows;
- no code within a couple of minutes: do not press "send again" repeatedly, wait;
- the number was accepted but the service asks for another verification method: that is the service's call.
Codes from short codes
In the US, verification codes often come not from a regular number but from a short code of 5–6 digits. Such messages do not reach every number: it depends on the carrier and the line type. If a code from an American service is late, repeating the request usually does not help: let the order time out with a refund and take another number.
What it costs
The price depends on the service and country pair, not the country alone. For some services an American number costs more than popular Asian countries; for others it is cheaper than numbers in high demand. The exact price shows before you pay, so compare options first.
Activation or rental
One code needs only a one-time activation. If the service will ask for a code on the same number again (a new device or two-factor authentication), you need a rental, if it is available for that service and country.
Frequently asked questions
Can I use an American number if I am not in the US?
Yes. The number receives SMS wherever you are: the code appears in your order. But the service may separately check your region, IP address or payment method: those are its rules.
How is a US number different from a Canadian one?
Both use +1; they differ by area code. Some forms show them as different countries. In Hush SMS you choose the United States and get an American number.
Why did the US code come from a short number?
American services often send codes from short codes of 5–6 digits. That is normal: the code still appears in your order if the carrier delivers it.
Check Hush SMS on one order: if the code does not arrive within 15 minutes, the money returns to your balance automatically.
