Poland (+48) verification codes: checklist, API steps and fixes

Pre-flight: what do I need before testing Polish sign-ups?

Run down this list once, and the first Polish order tends to be uneventful:

1. Credentials. Generate a Bearer key in the Developer console (it begins with or_live_). Separate keys for staging, CI and production make rotation painless.
2. Identifiers. Poland is pl. Pull service ids from GET /api/v1/services instead of hard-coding display names.
3. Funds. Top up the wallet; each price is visible before you order.
4. Delivery target. Register an HTTPS webhook and keep its secret out of source control. Polling works too if inbound traffic is blocked.
5. Rate budget. The API allows 300 requests per minute per account, so throttle parallel suites accordingly.
6. Scope. Only verify accounts that belong to your own product, your company or your client, and follow each service's terms alongside our Acceptable Use Policy.

For pipelines specifically, see SMS OTP testing in CI pipelines.

Which services currently send codes to +48 numbers?

For OTP routing, Poland is one of the broader entries in the catalogue, covering more than 2,300 services. The current snapshot of popular ones includes Facebook, Instagram, TikTok, WhatsApp, Telegram, Viber, Signal, Snapchat, Discord, X (Twitter), LinkedIn, Google (Gmail & YouTube), Amazon, AliExpress, Uber and Netflix.

Treat that list as a starting point rather than a promise. Availability on any route changes through the day, so ask the prices endpoint for the specific pair before every order.

What are the exact steps for the Poland OTP API?

Using the SMS verification API at https://otproute.com/api/v1, an automated test does the following:

1. GET /api/v1/prices?country=pl&service=<id> confirms a live price for that service in Poland.
2. POST /api/v1/activations with {"service": "<id>", "country": "pl"} returns the +48 number and an activation id.
3. Your test types the number into the sign-up form and requests the SMS.
4. The handler receives activation.sms_received; if it sees activation.expired or activation.cancelled, it marks the run as not delivered.
5. Without a webhook, read GET /api/v1/activations/{id} every few seconds until the code appears or the window ends.
6. Call POST /api/v1/activations/{id}/cancel when a test is torn down early.

Validate the X-OTPRoute-Signature header before trusting any payload: it holds t=<unix>,v1=<hex>, where v1 is HMAC-SHA256 of <t>.<raw body> signed with the endpoint secret. Reject anything with an old timestamp and make the handler idempotent on the activation id. The webhook security guide shows the check in detail.

Can my operations team order a Polish number without the API?

Yes. In the OTP Route dashboard, open the OTP Gateway, choose Poland, search for the service and confirm the displayed price. After ordering, copy the Poland verification number into the app's verification screen and watch the activation card; the SMS text appears there once received. Nothing needs installing, and the same wallet funds both the browser and the API.

What makes Polish numbers and messages different to handle?

Poland uses a closed numbering plan with no trunk prefix: every number, mobile or fixed, is nine digits after +48. That makes validation pleasantly strict. Reject inputs that do not reduce to nine national digits, remove spaces and dashes users add in groups of three, and store +48 plus the nine digits as a single E.164 string. A stray leading zero is a typo, not a prefix to preserve.

Verification messages often arrive in Polish when the account language is Polish. Characters such as ą, ę, ł and ż fall outside the GSM 7-bit alphabet, so if you send your own Polish OTP texts, expect shorter segments and test the template as it actually renders on a handset. When parsing incoming codes, key on the digits and ignore the words around them.

Common reasons to test here: a product entering the Polish market, localisation QA for Polish-language flows, regional teams that look after business accounts across Central Europe, and apps whose customers include Polish speakers living elsewhere in the EU.

Troubleshooting: why is the +48 code missing?

• The window is still open. Give it the full 20 minutes before concluding anything; you are charged only if a code arrives.
• The service may reject virtual numbers. Some platforms do, and when that happens the automatic refund puts the full amount back into the wallet.
• The route is busy. Retry later, or test a different service route.
• The test is looping. Ordering again every few seconds burns your request budget; add backoff.

Does Poland have dedicated numbers, and how do payments work?

Not as a self-serve product. Dedicated Virtual Numbers, from $1.95/month, are offered only in the United States and Canada. For a long-term Polish line, email [email protected] to ask; local rules decide whether that is possible, so there is no promise of one.

Payments go into a single prepaid USD wallet: no plan, no monthly fee, top-ups by card or USDT/USDC, and a PDF invoice emailed for each top-up. Developers can request sandbox mode on a development account to receive simulated numbers and codes while building the integration. See pricing for live rates.

Frequently asked questions

How can I test a Polish sign-up flow if nobody on the team has a +48 SIM?

Order a +48 number for testing on the OTP Gateway and use it in the flow. The code appears in the dashboard and can be sent to your webhook.

What is the Poland country code in OTP Route API calls?

It is pl, used both in POST /api/v1/activations and in the prices query.

How many digits does a Polish phone number have?

Nine national digits after +48, with no trunk zero. That fixed length makes server-side validation straightforward.

What does it cost to receive a Poland SMS OTP?

Prices start from $0.20 per code and vary by service. The dashboard and the prices endpoint show the exact figure before you order.

Will I lose money if a Polish activation expires empty?

No. An activation that ends without a code, or one you cancel, is refunded to the wallet in full.

Can I simulate the whole Poland flow before going live?

Yes. Ask for sandbox mode on a development account to get simulated numbers and codes without spending wallet funds.
