How to Get a +385 Croatian Number for Sign-Up Codes

Checklist: what to sort out first

People come to OTP Bolt for a Croatian number for a handful of reasons. A holiday-apartment host on the Adriatic coast wants guests to message a local number, not a personal one. Croatians living in Germany or Austria want a +385 account for something back home. A developer is testing an app before launching it in Zagreb. Each case starts the same way.

• [ ] Account created at /signup, with email plus a 6-digit code or with Google
• [ ] Wallet topped up once (card via Stripe or USDT / USDC), which unlocks ordering and exact prices
• [ ] App name confirmed, since prices differ per app
• [ ] Phone field of the app open and ready
• [ ] A clear answer to: do I need this number again later?

Which apps work with a Croatia phone number for verification?

Croatia has one of the wider app lists on OTP Bolt, with more than 1,700 apps on Instant OTP. Common picks include WhatsApp, Viber, Airbnb, Telegram, Google (Gmail & YouTube), Facebook, Instagram, TikTok, Uber, LinkedIn, Microsoft & Outlook, ChatGPT (OpenAI), Amazon and eBay.

Viber has long been popular in Croatia alongside WhatsApp, so it is worth checking both if you are setting up a contact line for guests or clients. Exact coverage and prices are live in the dashboard and do change. OTP Bolt is independent of all these apps; their names are their owners' trademarks.

From order to code in five moves

1. In the dashboard, open Instant OTP, select Croatia, then select the app.
2. Look over the price for that app (from $0.20 per code), then confirm the order.
3. Copy the +385 number. Its 20-minute window starts now.
4. Put the number in the app and request a verification SMS.
5. The code arrives in your live inbox, normally within a minute or two. Enter it in the app.

The number serves that one verification. If you need to receive SMS online on a Croatian number repeatedly, skip ahead to Dedicated Numbers.

Writing a +385 mobile number correctly

Croatia uses a trunk prefix, so the leading 0 you see in local writing disappears in international format. A mobile number written at home as 09x xxx xxxx becomes +385 9x xxx xxxx. Croatian mobile numbers start with 9 once the zero is gone.

In practice: choose Croatia (+385) in the form's country selector, then type the number without its first 0. Entering +385 09… is a frequent mistake and many apps will reject it or send the SMS nowhere.

Croatian is the official language. Local banks, shops and delivery services will typically send texts in Croatian ("Vaš kod je…"), while international apps use your account language.

The SMS never came: what now?

• Format first. Look for a stray 0 after +385. Fix it and request again.
• Resend. Many apps have a resend link; another SMS can sometimes arrive on the same order.
• Read the app's error. Some services do not accept virtual numbers. If so, try another country in OTP Bolt for that app.
• Cancel or wait it out. Cancelling before a code shows up refunds the full price to your wallet, and an order that reaches the end of its 20 minutes without a code is refunded automatically.

A code that reached your inbox is a completed order, so that charge stays.

Choosing a Dedicated Number as your Croatian second number

Pick a Dedicated Number over Instant OTP when the number has to keep working: login codes next season, account recovery, or a phone line guests can call about check-in. Prices start from $1.95/month.

Croatia is on request. Send a "Request a country" from the dashboard and the team looks into availability and price for a +385 number, and tells you if an address or ID check is needed before activation. Timing differs from country to country; by comparison, numbers in the United States, Canada and Puerto Rico can be bought and switched on by yourself in minutes.

With an active number you get:

• Unlimited verification texts in an SMS inbox
• Calls made from Chrome, Edge, Firefox or Safari, with no SIM
• Incoming calls answered right in the browser tab, logged with times and numbers
• Prepaid renewals from the wallet, an email reminder ahead of each one, and the option to release the number at any time

Testing a Croatian launch via the API

Before going live in Croatia, QA teams can call the REST API with an API key to order a +385 number, poll for the code and cancel leftovers. It shows quickly whether your form strips the trunk zero correctly and whether Croatian characters such as č, ć, š and ž survive in your SMS template. Docs: /developers.
