How to Use a Macao (+853) Number for OTP Codes and Calls
NumberFlare lets you receive a verification code on a Macao (+853) number with Instant OTP, starting from $0.20 per code, and you can also request a Macao Cloud Number for calls and SMS, starting from $1.95/month. Instant OTP is fully self-serve and refunds you if no code arrives. A Macao Cloud Number is arranged on request after our team confirms availability, price and any local address or ID requirement.
Is a +853 number the same as a Hong Kong or mainland China number?
No, and mixing them up is the most common mistake on sign-up forms. Macao has its own country calling code, +853. Hong Kong uses +852 and mainland China uses +86. If an app asks for your region, choose Macao specifically; a Macao number entered under Hong Kong or China will fail validation or send the code to the wrong place.
If your project spans the region, the Hong Kong and China pages explain what is available there.
Who typically needs a Macao virtual number?
Macao is a compact territory with a large flow of visitors and businesses linked to tourism and hospitality, so the reasons for wanting a +853 number tend to be practical:
- Businesses abroad that serve Macao customers and want a local-looking contact line.
- Developers and QA teams confirming that their sign-up flow handles +853 numbers correctly.
- Residents and frequent travelers who prefer a second phone number for sign-ups instead of exposing their personal mobile.
The first group usually needs a Cloud Number. The other two can often get by with Instant OTP alone.

Steps to receive a Macao SMS code
- Sign up with your email and enter the 6-digit confirmation code.
- Make your first wallet top-up, which unlocks purchases and displays per-service prices.
- Choose Instant OTP, pick the service, then choose Macao.
- Copy the +853 number into the app asking for verification.
- Read the code from the live inbox, usually within a minute or two.
Each number is reserved for 20 minutes. If the code does not come through in that time, you pay nothing and the funds return to your wallet automatically.
Formatting tips for Macao phone numbers
Macao numbers are eight digits after +853, and mobile numbers begin with 6. There is no leading zero to drop.
- Country picker present: select Macao (+853), then type the eight digits.
- Single input box: write +853 followed by the eight digits, without spaces.
Chinese and Portuguese are the official languages, so a verification message may be written in Traditional Chinese, Portuguese or English. You only need the numeric code.
Getting a Macao Cloud Number for ongoing calls
A Macao Cloud Number is not something you can buy in a few clicks; that instant option covers the United States, Canada and Puerto Rico only. For Macao, open the dashboard and choose Request another country, or email [email protected]. Our team replies with availability and pricing and explains whether an address or ID check is needed before activation. The timeline depends on those local requirements.
A Macao Cloud Number gives you:
- calling from Chrome, Edge, Firefox or Safari, with no SIM or app
- forwarding to your own mobile, plus voicemail
- call logs, contacts and an SMS inbox, though SMS depends on the specific number, since these lines are mainly voice
Choose it over Instant OTP when the number must stay yours, for example as a booking line for visitors or a contact number for local partners.
How payment works
Everything is paid from a prepaid USD wallet, topped up by card or by USDT/USDC. With crypto, the exact amount displayed, including decimals, must be sent on the chosen network. Your wallet balance is applied first at checkout, and PDF invoices are emailed automatically. Details are on the pricing page.
