Question 1

How do I buy a US phone number from GreatNumber?

Accepted Answer

Pick a number from our inventory, add it to your cart, and pay online. GreatNumber is a California-registered company founded in 2010, so you are buying from a real US business, not an anonymous reseller. After payment we send your account details and help you port the number to your carrier.

Question 2

Are these real US numbers I actually own?

Accepted Answer

Yes. These are real US phone numbers. It is a one-time payment and the number is yours for life — no monthly fees, no renewals, no hidden costs. After porting to your carrier you only pay your carrier's standard service fees.

Question 3

Can I use the number for SMS and app verification (e.g. WeChat)?

Accepted Answer

Once the number is ported to a carrier, it works like any normal US phone number with full voice and SMS. You can receive text messages and use it for account and app verification. We do not control third-party apps' own policies, so we cannot guarantee any specific service, but a properly ported real US number works for standard SMS.

Question 4

How long does it take to get my US number working?

Accepted Answer

We deliver your number details promptly after payment. Porting the number to your carrier (AT&T, T-Mobile, Verizon, or most VoIP systems) typically takes 3–14 business days, and our bilingual team assists you through every step.

Question 5

Do you offer support in Chinese?

Accepted Answer

Yes. GreatNumber provides full bilingual service in English and Chinese (中英双语服务), both online and at our 9 physical stores.

Question 6

Do I actually own the number after I pay?

Accepted Answer

Yes. It is a one-time payment and the number is yours for life — no monthly fees and no renewals. We deliver your number credentials within 24 hours of payment, and you can then port the number to your own carrier, so control of the number stays entirely in your hands.

Question 7

Do I need US ID documents to buy a number?

Accepted Answer

No US ID documents are needed for the purchase itself. When you port the number into a carrier, you follow that carrier's own account requirements, and our bilingual (English/Chinese) support team assists you through the process.

Question 8

Can I port the number to the carrier I already use?

Accepted Answer

Yes. We support porting to T-Mobile, AT&T, Verizon, and most other carriers and VoIP systems. The transfer typically takes 3–14 business days, and we assist you every step of the way.

Question 9

Do I need to buy a separate phone plan after purchasing?

Accepted Answer

The number itself is a one-time buyout. Calling and texting service is provided by the carrier you port the number into, under that carrier's own plan — the number price does not include a service plan.

Question 10

What happens if delivery or porting fails?

Accepted Answer

If we are unable to deliver the number for reasons on our side, it is handled under our refund policy. If a port runs into obstacles, our bilingual support team helps you resolve it — we have served over 10,000 customers in 15 years.
