From tele- and lexicon. Built from 208 regulator and numbering-plan sources and refreshed every week or month.

What Telexicon does
National regulators hand out telephone numbers in blocks: to mobile networks, landline carriers, VoIP providers and API platforms. Each regulator publishes those allocations in its own format, language and schedule. Telexicon collects them all, puts them into one consistent record, checks every update, and answers questions about any number in milliseconds.

Who it's for
Telexicon is used by teams that route calls, bill for them, register users against them, or need to trust a list of them.
OTT voice, chat and social apps, two-factor login services
The problem
Fake accounts sign up with numbers nobody can be reached on: freephone, premium rate, unallocated ranges, or virtual numbers rented by the thousand from an API platform. Each one costs you verification SMS, support time and fraud losses.
With Telexicon
Check the number at sign-up and get an allow, flag or block verdict with a reason. Block the bad ranges before you send a single code. Flag the grey cases for extra checks instead of turning real users away.
Carrier sales, rates and routing teams
The problem
Supplier ratesheets arrive weekly with thousands of dial codes. Some codes are priced as one network but belong to another, or are billed as mobile when the regulator says they are landline. Mistakes show up as margin loss and billing disputes weeks later.
With Telexicon
Upload the ratesheet and get every row checked against the regulator's own allocations. Codes billed to the wrong network or type are flagged. Coarse codes that span several operators are shown with each holder, so you can split them correctly.
Banks, fintechs, marketplaces, telecoms fraud desks
The problem
A phone number is part of a customer's identity, but a VoIP or API-platform number is far easier to obtain and discard than a mobile on a real network.
With Telexicon
Add number type, operator type and assignment status to your risk score. Every answer carries a reason code your analysts can explain to an auditor.
Customer operations, marketing and data quality teams
The problem
Customer databases fill up with mistyped, truncated and out-of-service numbers. Agents waste dials, SMS campaigns go to landlines, and nobody can say how much of the list is usable.
With Telexicon
Upload a list of up to a million numbers. Get a summary by number type and a row-by-row file showing which numbers are mobile, which are landline, and which are invalid or unallocated, with the reason for each.
MVNOs, CPaaS platforms, calling-card and voice service providers
The problem
Rating, routing, fraud rules and number provisioning all need the same reference data, and building it means tracking hundreds of regulators who change formats without notice.
With Telexicon
Take one consistent, versioned dataset through one API. We track the regulators, catch format changes, and review every material update before it reaches your lookups.
Capabilities
Every tool reads the same versioned numbering data. Pick the one that matches the size of the question.
1 number
allow, flag or block for sign-up to calling apps, with a stable reason code.Up to 1,000,000 numbers
Every prefix
Optional, one number at a time
On a single number in the portal, Telexicon can also ask which network serves it today. The regulator's allocation and that serving-network answer stay separate. When both come back, a comparison says whether the number has moved away from its range owner.
Lists, ratesheet checks, and partner API lookups use the regulator record only. Serving-network lookups are billed per query.

Vocabulary
What kind of number the plan says it is, and what kind of operator holds it. Telexicon answers both and never lets one overwrite the other.
The service class in the national numbering plan. Regulator truth, taken range by range.
A UK 056 or French 09 number stays voip. A mobile range held by a CPaaS brand stays mobile.
What kind of business holds the range. Curated by our analysts and checked on every new holder that appears in a regulator file.
OTT registration guidance
Calling and messaging apps lose money when accounts register with numbers nobody can be reached on: freephone, premium rate, unallocated ranges, numbers rented by the thousand from an API provider.
Every lookup returns an ott_registration verdict and a short reason code. The rules are evaluated in a fixed order and the first match wins, so the same number always gets the same answer, and you can explain it.
This is registration guidance. It does not claim the caller ID presented on a call is genuine.
How data changes
Each source runs on its own schedule and every change becomes a versioned release. A routine update ships on its own. Anything that removes ranges or changes who wins a lookup waits for a person.
Fetch
The source is pulled on schedule, weekly or monthly, from the regulator's register or published plan.
Stage
Ranges are written to an immutable candidate. Lookups keep answering from the current release.
Evidence
Signed checks compare the candidate with the published plan: rows, number space, invalid ranges, winner changes.
Release
Routine changes inside the source's policy publish automatically. Material ones go to a reviewer who approves with MFA.
Roll back
Every release is a manifest. Returning to the previous one is a single, audited switch.
Coverage
Each country is fed from the regulator's own register where one is published, and from the national numbering plan filed with the ITU where it is not. Every source is also reviewed by an analyst on a rotation.
| Country or territory | Code | Source | Refresh |

Ways to use it
The same data sits behind every way in, so an answer in the portal matches the answer your systems get from the API.
Web portal
Check single numbers, upload lists and ratesheets as CSV or Excel, and download results. No code needed. Access is role-based, with MFA for sign-in.
API
Call the lookup from your sign-up flow, fraud engine or switch. One JSON envelope, vendor-neutral source names, and a correlation id on every request.
Batch jobs
Large lists run in the background and come back as a CSV. Start one from the portal, close the tab, and download it when it is ready.
Data exports
Export every stored prefix and original holder for a number type, for one country or the whole world, to load into your own routing or rating tables.
Developers
Partner API lookups return the regulator's allocation: range owner, number type, operator type, and the OTT verdict. A serving-network answer exists only on a single number in the portal, and it is not part of the partner key.
