What you get with a rented +32 number
You get a real Belgian mobile number for a single verification. That matters because many services reject VoIP lines (see non-VoIP number). Enter the number in the service’s signup form, request the code, and watch the app. The SMS usually arrives within a minute and appears on the number’s card, as in the screenshot.

Every number comes with a timer called the activation window. If no SMS arrives before the timer runs out, the activation cancels and the full price goes back to your balance automatically. You pay only for numbers that actually received a code, and the refund needs no support ticket.
What Belgium numbers cost right now
Belgium rentals start at $0.04, and the price depends on the service you pick. Each service shows its price before you rent, and one rental covers one verification. You top up your balance by card or crypto, and each number you rent is paid from that balance.
Prices and stock for Belgium change through the day. If the service you need shows no Belgian numbers, try again later or pick one of the other 35+ countries in stock, as long as the service accepts numbers from that country.
Who this is for: travellers, expats and teams
Travellers can use a +32 number to sign up for a local app during a week in Brussels or Ghent, and their home SIM never gets exposed. Expats can set up a second account tied to a Belgian number and keep their personal number off yet another signup list.
QA teams testing one-time-password flows for Belgian users can rent numbers through the REST API, which has examples in Python, Node.js, Go and PHP. A test script can request a +32 number, trigger the OTP, read the code and confirm the login step without anyone touching a phone.
Why do services check the country of your phone number?
What the +32 prefix tells a service
A sign-up form reads a phone number before it sends a single SMS. The country code +32 tells the service the account belongs in Belgium, so it can set the region, currency display, store catalogue and default language. Belgium has three official languages (Dutch, French and German), so some apps ask you to pick one when they see a +32 number.
The digits after the country code matter too. Belgian mobile numbers start with 4 after +32 and have nine digits in total, for example +32 4xx xx xx xx. Geographic landlines start with an area code instead, such as 2 for Brussels. A validation library can tell from that pattern alone whether a number is a mobile line, and many services only send verification codes to mobiles.
Why real mobile numbers work where VoIP numbers fail
Many platforms run a carrier lookup before sending a code. The lookup returns the network that issued the number and its line type: mobile, landline or VoIP. Internet-issued numbers are cheap to create in bulk, so many sign-up flows reject them or put them through extra review.
A number issued by a Belgian mobile operator comes back from that lookup as an ordinary mobile line. That is why a non-VoIP number on a real SIM gets the code in cases where an app-based number gets an “invalid number” error or never receives the SMS. MarioSMS rents real mobile numbers, one verification at a time, so the +32 number you use passes the same line-type check as a local resident’s SIM.
When a Belgian number matters for travellers and expats
Some local services restrict features or eligibility by number country. A food delivery app, a regional streaming catalogue or a municipal booking portal may expect a +32 mobile before it shows Belgian content or accepts a sign-up. Travellers on a foreign SIM can hit that wall on day one, and expats waiting on a local contract can stay stuck for days. Renting from the Belgium numbers page gives you a +32 mobile for that one sign-up, priced from $0.04 depending on the service.
How do you rent a Belgium number in the MarioSMS app, step by step?
The steps are the same on iOS, Android and the web app at app.mariosms.com. You choose the service first and the country second, so the price you see is the price for that service on a +32 number. The screenshot shows that order in the country list.
Pick the service, then Belgium in the country list
Once you confirm, the app holds the number for one verification and starts a timer. You paste the number into the sign-up form, request the code and keep the app open. As the screenshot shows, the code usually lands on that same screen within a minute.
The code arrives in the app, usually within a minute
Top up your balance by card or crypto
- Open the iOS or Android app, or sign in at app.mariosms.com.
- Open the balance screen and add funds by card or crypto.
- Check that the balance covers the service you plan to use.
Belgium numbers start at $0.04, and the exact price depends on the service. A small top-up covers one sign-up. If a rental never receives a code, the refund goes back to this same balance.
Pick the service, then Belgium in the country list
- Search for the app or website you are signing up for.
- Open the country list and select Belgium (+32).
- Check the price shown for that service and confirm the rental.
The same +32 number can cost different amounts on different services, which is why the service comes first. The Belgium numbers page lists what is in stock if you want to compare before you top up.
Enter the number and request the code
- Copy the +32 number from the rental screen.
- Paste it into the service’s sign-up form.
- Tap the button that sends the one-time code.
Belgian mobile numbers have nine digits after +32 and start with 4. Some forms have a separate country dropdown. Set it to Belgium and paste only the nine digits. Do not add the domestic leading 0 after +32, since many forms reject that format.
Read the code in the app or dashboard
- Go back to the rental screen in the app or the web dashboard.
- Wait for the SMS. It usually arrives within a minute.
- Type the code into the sign-up form before the timer runs out.
The timer is the activation window for that rental. If no SMS arrives before it ends, the activation cancels and the full price goes back to your balance automatically. A $0.04 Belgium rental that never gets a code costs you nothing, and you can rent another number from the same list.
Which services and prices should you expect for Belgium numbers?
On MarioSMS, prices start at $0.04 per number. The final price depends on two things: the service you pick and the country. The Belgium numbers page lists the current price and stock for each service, and those figures change during the day.
Why the same country costs different amounts per service
Each Belgian number can only be used once per service. When a service already has many accounts tied to the numbers in stock, fewer clean numbers are left for it, and those cost more. Some services also filter numbers more strictly, which makes a working number harder to supply. A service with few registrations in Belgium can stay near the $0.04 floor. A large messaging app costs more on the same Belgian number.
Generic numbers versus service-specific numbers
Rent the number under the exact service you plan to verify. The price and stock you see for that service mean the number has not already been used to register an account there. If you rent under one service and send the code request from a different app, the number may already belong to an account on that app. The SMS may then never arrive, or it may arrive for someone else’s account.
| Choice | What you get | Risk |
|---|---|---|
| Number rented for the exact service | Matched to that service’s sign-up | Low, and refunded if no SMS arrives |
| Number rented for a different service | Price may be lower | The code often never arrives |
What to do when Belgium is out of stock for your service
- Wait 15 to 30 minutes and refresh the list. Stock comes back as new numbers are added.
- Check whether the service actually needs a Belgian number. Many services accept any country and only use the number to deliver the code.
- If Belgium isn’t required, pick another country that has stock for the same service. MarioSMS has 35+ countries to choose from.
- If Belgium is required, keep checking the list. Don’t rent a number under a different service.
Testing Belgian OTP flows through the REST API
QA teams can rent Belgian numbers through the MarioSMS REST API instead of the app. The docs include examples in Python, Node.js, Go and PHP. A typical test script requests a number for the service under test and triggers your app’s OTP send. It then polls for the code and checks the result. Each activation has its own timer, and failed runs are refunded to your balance, so a nightly suite only pays for the Belgian codes that actually arrive.
What should you do when no SMS arrives on your Belgium number?
A missing Belgian code usually has one of three causes. The number was mistyped, the resend was pressed too early, or the service filters that number range. Each Belgium number you rent stays reserved for you while its activation timer counts down, as the screenshot shows. That gives you a fixed window to work through the checks below.
A Belgium number, reserved while the timer runs
You don’t pay for a code that never shows up. If the window closes without an SMS, MarioSMS cancels the number activation and refunds the price to your balance on its own, as the image below shows. You don’t need to open a ticket or send a request.
Follow these steps in order while the timer is still running:
- Check that the number on the service’s form has the +32 prefix and no leading 0.
- Wait 60 seconds. Most codes appear in the app or dashboard within a minute.
- Press resend on the service once.
- Keep the activation open and watch the timer.
- If the timer expires, wait for the automatic refund and then rent a fresh number.
Check the number format and the +32 country code
Belgian mobile numbers have 9 digits after the +32 country code and begin with 4, as in +32 4xx xx xx xx. Inside Belgium people write them with a leading 0 (04xx). If the form already shows +32 in a country picker, type only the remaining digits. Entering “+32 04…” adds an extra zero and the SMS never reaches the number.
Resend once, then wait inside the timer
If no code appears after about 60 seconds, press resend on the service one time. Repeated taps can trip the service’s rate limits, and that delays every later attempt. Keep the app or app.mariosms.com open and let the timer run. A resent code often arrives 30 to 90 seconds after the first one.
What happens when the timer runs out
When the activation window ends without an SMS, the activation is cancelled and the price goes back to your balance automatically. The number is released at that point, so a code sent later will not reach you. Start a new activation. Don’t resubmit the old number on the service’s form.
When to switch service or try a fresh number
Rent a new Belgium number straight after the refund if the first one expired even though the format was correct and you resent only once. Some services block specific number ranges, and a different number often gets past that block. If two or three fresh numbers fail on the same service, check that service’s stock on the Belgium numbers page.
What are the legitimate limits of a rented Belgium number?
A rented Belgium number handles one verification inside one activation window. It suits a short list of jobs and is a bad fit for others. The full rules are on the acceptable use page, and the summary below follows them.
Uses that fit: privacy, second accounts and testing
- Privacy hygiene. You can sign up for a marketplace, forum or delivery app in Belgium without giving out the number on your personal SIM.
- Second accounts for legitimate reasons. For example, a separate work profile, a project account or a community page that you run yourself.
- QA and OTP testing. You can check that your own app sends an OTP to a +32 number, that the text displays correctly and that it arrives within your timeout. The REST API includes Python, Node.js, Go and PHP examples for scripting these checks.
Uses that do not fit
- Opening new accounts on a service that has banned you.
- Pretending to be another person, a company or a Belgian resident in order to mislead anyone.
- Mass sign-ups meant to spam, scrape or get around a platform’s per-user limits.
None of these is acceptable use, whatever the country of the number.
Why a one-time number is a poor choice for long-term recovery
You can use a rented number only during its activation window. After the timer ends, you can’t receive anything on it. If a service later sends a login code or a password reset to that number, you never see the SMS and the account can be locked. For any account you plan to keep, change the phone number to one you own as soon as signup is done. Then set two-factor authentication to your own number or to an authenticator app.
Belgium phone number for SMS: frequently asked questions
How much does a Belgium number for SMS cost?
MarioSMS prices start at $0.04 per number. The exact price for a +32 number depends on the service you need the code for, so one app can cost more than another. The Belgium numbers page shows the current price for each service before you rent. You pay once for each verification.
How long does the code take to arrive?
Most codes show up in the MarioSMS app or dashboard within a minute after the service sends them. Every number has a timer that marks its activation window, and the code has to arrive before it runs out. If nothing comes after 2 or 3 minutes, check that you entered the number with the +32 prefix and in the format the service expects.
Do I get my money back if no code comes?
Yes. If no SMS arrives before the timer ends, the activation cancels and the price goes back to your MarioSMS balance automatically. You don’t need to open a ticket or ask for it. You can spend the refunded amount on a new Belgian number or on a number from another country.
Can I use the same Belgium number twice?
No. Each rental covers one verification during one activation window. After the timer ends, the number stops receiving messages for you. If a service sends a second OTP later, for a login or a password reset, you won’t see it. For a new code, rent a new number.
Do I need to be in Belgium to use a +32 number?
No. The SMS goes to a real Belgian mobile number, and MarioSMS shows the code in the iOS app, the Android app or the web app at app.mariosms.com. You can read it from any country with an internet connection.
Can I get Belgian numbers through an API?
Yes. MarioSMS has a REST API with examples in Python, Node.js, Go and PHP. QA teams use it to rent a +32 number, read the incoming code and test OTP flows automatically. Your balance pays for API rentals, and you can top it up by card or crypto.
