International Number Search and Order Made Easy

As we at Telnyx have continued to expand our product offering and services outside of the US, we realized that our International Number Search and Order process needed a facelift.

While we have always boasted a wide range of international numbers, the original process for ordering these numbers was a bit manual for both our users and our support team.

In order to streamline International Number Search and Order, our teams have been working on augmenting the existing API, adding a new API endpoint, and improving the UI in Mission Control. The resulting changes will automate the process and give users instant visibility into the required documentation, end-user information, and emergency services requirement to purchase and activate international numbers. Ultimately, we have decreased the time to provide the numbers and simplified user interaction.

Users purchasing international numbers will now be able to:

1. Query for document requirements via API by country and number type
2. Reserve their desired numbers for a period of up to 48 hours while gathering the required information and documents
3. Submit information and required documents via the API and portal
4. Be notified and alerted on the imminent expiration of reservation period
5. Be notified and alerted on the success or failure of activating the desired numbers.

Updating the API and adding new features will make bulk number ordering a whole lot easier and faster in international markets. If you’re ready to try it out, head over to our Developer Center where you’ll find all the documents to get started.

If you have questions about our international offering, don’t hesitate to reach out to a member of the Telnyx team.

FAQ

How do I buy a Telnyx phone number?
Create an account, search the inventory by country, type, and features, then purchase and assign the number to a connection. Verify any required address or business details during checkout to meet local regulations.

What types of numbers can I buy with Telnyx?
You can choose local, toll-free, and mobile numbers in many markets, with options for voice, SMS, and MMS. Confirm capabilities by checking supported messaging types for the number you select.

Can I use my Telnyx number for SMS and MMS?
Yes, but support for SMS and MMS depends on the number and country. If you plan to send media, compare formats and handset behavior in SMS vs. MMS before you buy.

How fast are numbers activated after purchase?
Most numbers activate immediately once you complete payment and assignments. Some regulated markets require document review, which can add processing time.

What compliance documents might be required to buy numbers internationally?
Requirements vary by country and number type, and can include proof of address, business registration, and government ID. Prepare accurate documents and ensure your use cases align with local voice and messaging rules.

Can I port my existing numbers instead of buying new ones?
Yes, you can submit a port request with a recent invoice and a signed letter of authorization. After approval, schedule the transfer window and test routing to confirm inbound and outbound traffic.

How should I test a new number for messaging at scale?
Start with a small internal send to validate encoding, delivery receipts, and opt-out handling. For media campaigns, plan contact flows using group or broadcast messaging and run programmatic checks through an MMS API before ramping volume.
