Danish +45 Numbers for Verification and Business Calls
Yes, you can get a Denmark (+45) number on NumberFlare: Instant OTP gives you a number for one verification code from $0.20 per code, charged only if the code arrives, and a Cloud Number gives you your own line for calls and SMS from $1.95/month. Danish Cloud Numbers are available on request, with our team confirming availability, price and any address or ID check.
How do Danish phone numbers work?
Denmark keeps things short. Every number is eight digits after +45, with no area codes and no leading zero, whether it belongs to a mobile or a landline. That makes Danish numbers easy to enter correctly:
- Select Denmark (+45) in the country list of the app or website.
- Type the eight digits that follow +45, nothing more.
- If there is only one field, paste the full number from your NumberFlare inbox, plus sign included.
Greenland (+299) and the Faroe Islands (+298) have their own country codes, so a +45 number is always a number from Denmark itself. Texts from Danish companies are normally written in Danish, although the code you need is plain digits.
Which services send OTP codes to +45 numbers?
Right now, Instant OTP covers more than 1,700 services in Denmark. Some of the most requested:
- Telegram
- Google (Gmail & YouTube) and Microsoft & Outlook
- Facebook, Instagram, Snapchat and TikTok
- ChatGPT (OpenAI) and Claude
- Discord, Signal and Viber
- Airbnb, Uber and Amazon
The list changes with live supply. If a service you expect is missing, check later in the dashboard. We are not affiliated with any of these brands, and you remain bound by each one's terms of use.
Receiving a Danish code: the short version
- Open an account with your email and the 6-digit verification code.
- Put money in your wallet by card, or with USDT or USDC crypto. Purchases unlock after the first top-up.
- Choose your service, then Denmark, and check the price on screen.
- Enter the +45 number in the service and trigger the SMS.
- Watch the live inbox: Danish codes normally show up within a minute or two.
A Denmark phone number for verification stays active for 20 minutes. You only pay when a code is delivered. If none comes, the wallet is refunded automatically.
When the code is slow or missing
Give the full 20 minutes before deciding it failed, since some platforms queue messages. Then check the basics: did the app keep Denmark as the country, and did you enter all eight digits? If everything looks right, the service may simply not accept virtual numbers. In that case the refund covers you, and you can try a new +45 number for the same service at a later hour. Pressing resend repeatedly rarely helps and can make the service slow down.
Can I get a Danish Cloud Number for calls?
Yes. A Danish Cloud Number starts from $1.95/month, but it is not instant. Self-serve, same-day Cloud Numbers are limited to the United States, Canada and Puerto Rico. For Denmark, use Request another country in the dashboard. Our team confirms whether a +45 line is available and at what price, and tells you if Danish rules call for an address or ID check before activation. Timing varies.
After activation you can make and take calls in Chrome, Edge, Firefox or Safari, forward calls to your mobile, use voicemail, and keep call logs and contacts in one place. Calls are the main feature; SMS depends on the specific number. The Denmark virtual number page has more on the business side.
What a virtual +45 number is good for, and what it is not
A Danish second phone number makes sense for a company selling to customers in Copenhagen or Aarhus, a Nordic support team working remotely, someone relocating who wants a contact number before a local SIM is set up, or developers checking their own app's Danish sign-up flow.
It is not a replacement for MitID, the national digital ID that Danish banks and public services use to log you in. MitID is tied to your identity, and a number you buy does not change that. Choose Instant OTP for a single code; choose a Cloud Number when the line must stay with you. Planning for the wider region? See Sweden and Norway.

Frequently asked questions
For one-time codes, yes: Instant OTP needs no documents. A Danish Cloud Number is arranged on request, and local rules may require an address or ID check first.
No. Danish numbers have no trunk prefix, so you enter +45 and then the eight digits.
One code through Instant OTP starts from $0.20, and the exact price depends on the service. If no code arrives within 20 minutes, you are not charged.
An Instant OTP number covers one code only, so it is a poor fit for an account you want to keep. For long-term use, request a Danish Cloud Number from $1.95/month.
You should not expect that. MitID and Danish banking logins are linked to your personal identity, and NumberFlare does not offer a way around those checks.
It depends on availability and on any verification needed under local rules. Our team gives you the details after you send the request from the dashboard.
Card payments and crypto top-ups in USDT or USDC go into a prepaid USD wallet. For crypto, send the exact amount shown on the network you chose so it is credited correctly.
Yes, for genuine uses like guarding your private number, signing up a business or testing your own product. Follow each service's rules and keep to one account per real person or company.
