Receive +853 Verification Codes in Macao, by API or Dashboard
Yes, OTP Bolt can give you a Macao (+853) phone number for verification: Instant OTP numbers receive one code each, from $0.20 per code, through the dashboard or the REST API. A Dedicated Number that stays yours, from $1.95/month, is available for Macao on request, with availability, price and any address or ID check confirmed by our team before activation.
Testing a sign-up flow that expects a +853 number
Most teams that ask us about Macao are not looking for a phone. They are shipping an app, a booking site or a loyalty program that has to accept Macanese customers, and the phone field keeps breaking in odd ways: a validator that rejects eight-digit numbers, a country picker that lumps Macao in with Hong Kong, or an SMS template that never reaches a real handset.
OTP Bolt lets you run that flow end to end against a real +853 number. Create an API key in your account, then:
- Order an Instant OTP number for Macao and the service you are testing.
- Submit that number in your own sign-up form, exactly as a customer would.
- Poll the order until the code text arrives, then read it in your test script.
- Cancel if your system never sends anything. The charge returns to your wallet.
Endpoints, authentication and response formats are on the developer page. Keep it to your own product and your own QA accounts.
What +853 numbers look like in a form
Macao has no trunk prefix, so there is no leading 0 to strip. Mobile numbers are eight digits and usually begin with 6. In international format you write +853 followed by those eight digits, with no extra characters.
A few things worth checking in your own forms:
- Is Macao listed separately in the country dropdown, with +853 and not +852?
- Does your length check allow eight digits after the code?
- Does the SMS template render traditional Chinese characters? Chinese and Portuguese are the official languages, and English is common in business, so codes may arrive in any of the three.
If a code arrives garbled in the dashboard, that usually points at an encoding issue on the sending side, which is exactly what a test run should catch.
Which apps can send codes to a Macao number?
Instant OTP for Macao currently covers more than 1,600 apps. Among the names people search for most: WeChat, WhatsApp, Telegram, Signal, LINE, KakaoTalk, Google (Gmail & YouTube), Facebook, Instagram, Microsoft & Outlook, Discord, ChatGPT (OpenAI), Airbnb, AliExpress and Alibaba.
Coverage shifts as apps change their own rules, so treat the dashboard as the live source. Some apps decline numbers that are not tied to a SIM, and that is one reason every Instant OTP order carries a refund window.
Getting one code without writing any code
You do not need the API to use a Macao phone number for verification. The dashboard does the same job by hand:
- Open an account at signup; a Google login or an emailed 6-digit code both work.
- Put money in the wallet. Ordering, and the exact Macao price list, open up after that first deposit.
- Pick the app, choose Macao, and order an Instant OTP number.
- Copy the +853 number into the app and ask it to send the code.
- Watch the live inbox. Expect the code there in roughly a minute or two.
Prices start from $0.20 per code; the exact figure depends on the app and is listed on pricing.
The 20-minute window, and what to do when it closes empty
Each order stays open for 20 minutes. If no code lands in that time, or you cancel before one arrives, the full price returns to your wallet automatically. Once a code has been delivered, the order is final and is not refunded.
When nothing shows up, check the obvious first: did you type all eight digits, and did the app actually confirm it sent an SMS? The app may let you resend, and another SMS to the same +853 number is sometimes possible. If the window still closes empty, the refund is already in your balance, and you can try again later or pick a different country if the app allows it.
Should you keep a Macao number instead?
Instant OTP is built for a single code. If the app will text you again later, for a new login or an account recovery, a number that disappears after one use becomes a problem. That is the moment to look at a Dedicated Number, from $1.95/month.
With a dedicated line you get an SMS inbox that keeps receiving verification texts on the same number, calling from Chrome, Edge, Firefox or Safari without a SIM, inbound calls that ring in the browser, and a call log. You pay each term up front from the wallet, an email warns you before it renews, and releasing the line is up to you at any point.
For Macao, dedicated numbers are handled on request. Use "Request a country" in the dashboard; the OTP Bolt team checks availability and price and tells you whether local rules call for an address or ID check before activation. Timing depends on the country. Self-serve activation with no wait applies to just three places: the US, Canada and Puerto Rico.
Paying for it
Everything runs on a prepaid USD wallet. You can top up by card through Stripe checkout or with crypto in USDT or USDC, and PDF invoices are emailed to you, which helps if the spend sits on a company card. Instant OTP orders and dedicated-number renewals both draw from the same balance.

Questions people ask
Can I get a +853 number if I don't live in Macao?
Yes. Instant OTP numbers for Macao can be ordered from anywhere, and the code appears in your browser dashboard. A Dedicated Number for Macao is on request and may involve an address or ID check.
Do I drop a 0 when entering a Macao number?
No. Macao numbers have no trunk 0, so you enter +853 followed by the eight-digit number.
Can my QA team receive SMS online for Macao automatically?
Yes, through the REST API with an API key: order a number, poll for the code, and cancel if your system never sends one. See the developer page for details.
What happens if WeChat or another app never sends the code?
An order that sees no code for 20 minutes is credited back to your wallet on its own. Cancelling before the 20 minutes are up returns the money just the same.
Is a Macao virtual number the same as a Hong Kong one?
No. Macao uses +853 and Hong Kong uses +852, and apps treat them as separate countries. Pick Macao in the dashboard if the app expects a Macanese number.
How much does a Macao phone number for verification cost?
Codes on a +853 Instant OTP number start from $0.20 per code, while a Dedicated Number starts from $1.95/month. Exact Macao prices show in the dashboard after your first top-up.
Can I use a second number from OTP Bolt to keep my personal one private?
Yes, that is one of the main reasons people use it. Choose Instant OTP for a one-off code, or request a Dedicated Number if you will need the same number again.
