Honduras Verification Numbers for Central American Product Teams

Why do teams building for Central America need a Honduran number?

Honduras is often one stop on a wider Central American rollout, next to Guatemala, El Salvador and Nicaragua. Each of those countries has its own dial code and its own routes, so a flow that works on a Guatemalan number tells you little about what a customer in Tegucigalpa or San Pedro Sula will see.

Three situations come up again and again:

• Market launch. A fintech, delivery or marketplace app opening in Honduras wants proof that its sign-up SMS actually reaches +504 numbers before ads go live.
• Spanish localisation QA. Honduras is Spanish-speaking, and codes usually arrive in Spanish. Some accented letters sit outside the basic GSM alphabet, so a template that uses them may be sent as Unicode and split earlier than expected. A real Honduran test number shows you the final rendering.
• Diaspora customers. Many Hondurans live in the United States and still manage accounts tied to a home number, which matters for remittance, telecom top-up and support teams.

Messaging habits lean heavily on WhatsApp in this region, so a +504 test that covers it reflects how most local users actually sign in.

What does a +504 number look like in a database?

Honduran numbers are eight digits long and the country uses no trunk prefix. A local number is written as XXXX-XXXX, and the international version simply adds the country code: +504XXXXXXXX.

That simplicity hides one trap. An eight-digit string without a country code looks like a valid number in several other countries, so a parser that guesses the region from length alone can attach the wrong code. Keep these habits:

1. Always store E.164: +504 plus eight digits, nothing else.
2. Strip the dash people type between the two halves.
3. Record the country chosen in your sign-up form and use it when normalising, rather than inferring it.

A consistent format also makes it easy to match an incoming code to the right test user when you run many activations in parallel.

Which services can I test on a Honduras verification number?

The current snapshot for Honduras shows more than 1,700 services. Popular ones include WhatsApp, Facebook, Instagram, Uber, TikTok, Telegram, Google (Gmail & YouTube), Microsoft & Outlook, Amazon, Discord, Snapchat, LinkedIn and ChatGPT (OpenAI).

What is routable changes over the day, so read the live list from the API or dashboard at the moment you order. A service that is missing at noon may be back later.

How do I receive Honduras SMS OTP codes through the API?

Authenticate against https://otproute.com/api/v1 with a Bearer key starting or_live_, created in the Developer console. The sequence for a Honduras OTP API test looks like this:

• GET /api/v1/services returns service ids; GET /api/v1/countries confirms that Honduras is hn.
• GET /api/v1/prices?country=hn&service=<id> gives the live price, so your script can refuse anything outside budget.
• POST /api/v1/activations with {"service": "<id>", "country": "hn"} reserves the +504 number and returns an activation id.
• The code reaches you as an activation.sms_received webhook, or through polling GET /api/v1/activations/{id}.
• POST /api/v1/activations/{id}/cancel ends an order you no longer need.

Webhook requests are signed. Compute HMAC-SHA256 over <t>.<raw body> with the endpoint secret, compare it with the v1 value in X-OTPRoute-Signature, and drop old timestamps. Handle duplicates by treating the activation id as the idempotency key. Limits worth remembering: 10 API keys, 5 webhook endpoints and 300 requests per minute per account. The developer overview and the integration guide go deeper into this SMS verification API.

What is the dashboard route for non-technical staff?

Not everyone on a launch team writes scripts. From the OTP Route dashboard, anyone with access can open the OTP Gateway, select Honduras and the service, read the price, and confirm the order. The +504 number appears on the order page; paste it into the app, request the code, and the SMS shows up on the same screen. Our QA testing page describes how teams split this work between engineers and testers.

My +504 code did not arrive. Now what?

An activation stays open for 20 minutes. You only pay if the code arrives: when the window ends empty, or you cancel, the full amount goes back to the wallet automatically.

Before ordering again:

1. Wait out the window instead of stacking a second order on top.
2. Check whether the service accepts virtual numbers; some decline them by design.
3. Try again later or with another service route for the same flow.
4. In automation, use a back-off rather than a tight retry loop, which burns rate limit and rarely helps.

Can I get a permanent Honduran line, and how is billing set up?

No self-serve long-term number exists for Honduras. Teams that need a persistent +504 line can email [email protected] to ask, but availability depends on local rules and cannot be promised. For comparison, Dedicated Numbers are sold only in the United States and Canada, from $1.95/month, and suit staging accounts that must log in again later.

OTP Route bills from one prepaid USD wallet with no monthly fee and no plan. Top up by card or with USDT/USDC; each top-up produces a PDF invoice by email. A sandbox mode for development accounts, on request, simulates numbers and codes so you can test the integration without spending funds. Follow each service's terms and our Acceptable Use Policy.

Frequently asked questions

Can I verify a Honduran account for my app without living in Honduras?

Yes. Order a +504 number from the OTP Gateway, trigger the code in your app, and read it in the dashboard or by webhook, from anywhere.

Does Honduras use a leading zero in phone numbers?

No. Honduran numbers have eight digits and no trunk prefix, so the E.164 form is just +504 followed by those digits.

What country code does the API expect for Honduras?

Use hn as the country id when you request prices or create an activation.

How long do I have to use a +504 number for testing?

Each activation lasts 20 minutes and covers one verification code.

Am I charged when the service never sends the SMS?

No. Missed or cancelled activations are refunded in full to your wallet automatically.

Is OTP routing for Honduras different from Guatemala or El Salvador?

Yes. Each country has its own routes and service list, so test the specific market your users live in.

Can I pay for Honduras verification numbers with stablecoins?

Yes. The wallet accepts card payments as well as USDT and USDC, and every top-up comes with a PDF invoice.
