Sierra Leone SMS verification for product and QA teams

What should you know about Sierra Leone's numbering before testing?

Sierra Leone's country code is +232 and domestic dialling uses a trunk 0. National significant numbers are eight digits, so a mobile written locally as 076 123 456 is +232 76 123 456 in E.164. That leading zero is the most common source of bad data: users type it, forms keep it, and the stored value becomes undeliverable.

Normalise on the way in. Remove spaces and punctuation, drop the trunk digit when a country code is present, and store the full +232 form. If your validation library has an outdated metadata file, refresh it before blaming the route.

Which languages and habits shape SMS in Sierra Leone?

English is the official language and Krio is spoken widely as a common tongue, but verification texts almost always come in English, so parsing is rarely complicated by script. The bigger factor is how people use phones: SMS remains a dependable channel, and mobile money and messaging apps are part of everyday life across much of West Africa.

That is why fintech, remittance and marketplace teams test here. A sizable Sierra Leonean diaspora in the United Kingdom and the United States also means overseas products meet +232 numbers at sign-up, and their onboarding flows need to handle them.

Can I receive Sierra Leone SMS OTP codes with OTP Route?

Yes. The OTP Gateway currently shows more than 1,000 services for Sierra Leone. Popular options in the live snapshot include WhatsApp, Facebook, imo, Telegram, Instagram, TikTok, Google (Gmail & YouTube), Microsoft & Outlook, Snapchat, Signal, LinkedIn, Amazon and Uber.

Availability moves through the day as routes are used and refilled, so read the list live before a test run instead of hard-coding it.

How does the API flow work for country `sl`?

Every call to https://otproute.com/api/v1 carries a Bearer key beginning or_live_, created in the Developer console. Look up ids with GET /api/v1/services and GET /api/v1/countries, confirm the rate with GET /api/v1/prices?country=sl&service=<id>, and create the activation using POST /api/v1/activations with {"service": "whatsapp", "country": "sl"}.

Then either subscribe to activation.sms_received on a webhook endpoint, or poll GET /api/v1/activations/{id}. For webhooks, verify X-OTPRoute-Signature (HMAC-SHA256 of the timestamp, a dot and the raw body, using your endpoint secret) and refuse stale timestamps. Our piece on securing OTP webhooks walks through it.

A practical tip for West African test plans: log the activation id next to your own test-case id. When a run fails, that pairing shows at a glance whether the code never came, came late, or arrived but was rejected by your parser.

How do non-developers get a +232 code from the dashboard?

Support agents and operations staff rarely need code. After signing up, open the OTP Gateway, pick the service, choose Sierra Leone, check the displayed price and confirm. The +232 number appears on screen; paste it into the app, request the SMS, and the code shows up beside the number when it lands.

If the app is slow to send, leave the page open; the countdown shows how much of the window remains, and a cancel button releases the money straight back to the wallet. Anyone on the team can repeat the same steps for a second service, which makes the dashboard handy for quick spot checks before a release.

What if no code reaches the Sierra Leone number?

The activation stays open for 20 minutes. If nothing arrives in that time, or you cancel, OTP Route returns the full amount to the wallet without any request from you. Then:

• wait and retry later, or try another route for the same service;
• confirm the service accepts virtual numbers, since some decline them;
• avoid hammering the order endpoint; space out retries.

Is there a long-term Sierra Leone line, and how do I pay?

There is no self-serve long-term number for Sierra Leone. Dedicated Numbers are sold only for the United States and Canada, from $1.95/month; teams that need a lasting +232 line can email [email protected], and local rules decide what is possible.

Everything else runs on a prepaid USD wallet with no subscription: top up by card or USDT/USDC and receive a PDF invoice for every top-up. A development account can be moved to sandbox on request, returning simulated numbers and codes for integration tests. See pricing.

Frequently asked questions

Can I test a +232 sign-up flow from outside Sierra Leone?

Yes. A +232 number for testing from the OTP Gateway receives the code wherever your team works, and you read it in the dashboard or through the API.

What is the Sierra Leone country id in the OTP API?

It is sl. Pass it in price lookups and in the body of POST /api/v1/activations.

How should I store Sierra Leone phone numbers?

Store E.164: +232 followed by the eight-digit national number, without the trunk zero.

How much does a Sierra Leone verification number cost?

Prices begin from $0.20 per code and depend on the service; the live rate is shown before you confirm.

Will codes come in Krio?

Rarely. Most services send verification texts to +232 numbers in English, though wording depends on each service.

Can a team keep one Sierra Leone number for repeated logins?

Not self-serve: gateway numbers cover one code each, and dedicated lines are US/Canada only. Email [email protected] to ask about other options.

Can I use the same integration for neighbouring countries?

Yes. Only the country id changes, so a test suite built for sl can add other West African routes, such as Liberia, by swapping that value.

What uses are allowed?

QA on your own product, plus running legitimate business accounts you control. Each service's terms still bind you, and the OTP Route Acceptable Use Policy covers every +232 order.
