Get a Dutch +31 Number for Verification Codes or Business Calls

Stuck at a sign-up form that wants a Dutch number?

It usually happens at an awkward moment. You are setting up an account for a Dutch market, testing your own app for users in Amsterdam or Rotterdam, or simply keeping your private mobile number off yet another platform, and the form will not continue without a phone number that can receive an SMS.

A Netherlands virtual number solves that without a Dutch SIM card or a trip to a phone shop. NumberFlare gives you two options, and picking the right one depends on how long you need the number:

• Instant OTP if you only need one verification code, right now.
• A Cloud Number if you need a +31 line you keep for calls, texts, logins and account recovery over the coming months.

The rest of this page walks through both, starting with the quick fix.

How to receive a verification SMS on a +31 number

Instant OTP is built for exactly one code. The process takes a couple of minutes:

1. Create a free account with your email address; a 6-digit code in your inbox confirms it.
2. Add funds to your wallet. Your first top-up unlocks buying.
3. Open Instant OTP, choose the service you are verifying, and select Netherlands as the country.
4. Check the price shown, then buy. A +31 number appears on screen.
5. Paste that number into the service's sign-up or verification form and request the SMS.
6. Watch the live inbox. Most Dutch codes show up there within a minute or two.

Each activation stays open for 20 minutes. If no code reaches the number in that time, you pay nothing: the amount goes back into your wallet automatically.

Which apps work with a Dutch phone number for verification?

Instant OTP in the Netherlands currently covers more than 3,000 services. Some of the most requested ones are:

• WhatsApp, Telegram and Signal
• Google (Gmail & YouTube) and Microsoft & Outlook
• Facebook, Instagram, TikTok and LinkedIn
• Amazon, eBay and Airbnb
• Uber, Discord and Netflix
• ChatGPT (OpenAI) and Claude

The list changes as our carrier partners update their routes, so the dashboard is the best place to check the current selection and price before you buy. Please use each service under its own terms. One account per real person or business is the safe rule, and nothing on NumberFlare is meant for getting around a service's restrictions.

Typing a Dutch mobile number into a form

Dutch mobile numbers are written locally with a leading 06, followed by eight more digits. In international format the zero drops away, so the same number becomes +31 6 and then those eight digits.

When a form has a separate country selector, choose the Netherlands (+31) and enter the number starting with the 6, without the zero. If the form only offers a single field, enter the full number with +31 in front. Adding both the country code and the zero is one of the most common reasons a code never gets sent.

Expect most messages from Dutch services to arrive in Dutch. You will usually spot the code easily anyway, since it is the only run of digits in the text, often next to words such as code or verificatiecode.

What if the code never shows up?

A missing SMS is rarely permanent. Work through these checks before you give up:

• Use the full 20 minutes. Some services queue their messages, so a slow code is not always a failed one.
• Check the number format you pasted, as described above.
• Find out whether the service accepts virtual numbers. Some platforms decline them on purpose. That is the reason Instant OTP refunds automatically when nothing arrives.
• Try again later with a fresh number. A new activation for the same service often succeeds where the first one did not.

If a service keeps rejecting Dutch numbers, you can also look at a nearby market such as Belgium or Germany, provided that fits the account you are creating.

Can I keep a +31 number for calls and texts?

Yes. For a number that stays yours while it renews, request a Netherlands Cloud Number. Cloud Numbers start from $1.95/month and include:

• Calling in Chrome, Edge, Firefox or Safari, with no app, SIM card or extra hardware
• An SMS inbox in your dashboard (SMS support depends on the specific number)
• Call logs and contacts
• Forwarding to your own mobile, plus voicemail

In the Netherlands, Cloud Numbers are available on request, not instant. Choose "Request another country" in the dashboard and our team will confirm availability and price. Dutch telecom rules can require an address or identity check before a number goes live, and the timing depends on that process. Only United States, Canada and Puerto Rico numbers are self-serve and immediate. You can read more on the Netherlands virtual number page.

Instant OTP or a Dutch Cloud Number: which do I need?

Think about what happens after today. If you need a single code for one sign-up and will never log in by SMS again, Instant OTP is the cheaper, faster choice. If the number will be tied to an account long term, used for two-step logins, printed on a website, or given to Dutch customers who call you, choose a Cloud Number. A one-time number cannot help you recover an account months later, but a second phone number you keep can.

Remote teams selling into the Dutch market often end up using both: Instant OTP to check how their own app's SMS flow behaves on +31 numbers, and a Cloud Number as the local contact line.

Paying for your Netherlands number

Everything runs from a prepaid USD wallet. Top up by card or with crypto (USDT or USDC), and the checkout takes the balance from there. Your first top-up unlocks purchases, and you will see the exact Instant OTP price for each service before you commit. See pricing for the starting rates of both products.
