How to Check Number Portability
Submit Number(s)
Submit the phone number or numbers through dashboard upload or API call.
HLR Query
The system performs an HLR query to return the serving network in real time.
Receive Data
Get information about the current operator, status, and line type in milliseconds.
Optimize Routing
Use that data within your messaging platform to route messages more efficiently.
Key Use Cases
SMS Aggregators and CPaaS
Reduce termination costs with direct‑to‑carrier routing.
Financial Services
Verify that a number is still with the stated carrier for fraud protection.
Regulatory Compliance
Some regions require correct carrier tagging on outbound traffic.
All lookup functions—single, bulk, and history—are available through REST API and SDKs, letting you embed Portability Check directly in provisioning, billing, or routing logic.
Pricing
Portability queries use the same usage‑based model as number validation: pay per successful result—no monthly minimums.
Got Questions? We've Got Answers
What is HLR?
The Home Location Register (HLR) is a central database in a mobile network that contains details about each subscriber, such as their current operator, status, and service settings. It helps determine the correct routing path to deliver SMS or calls to a mobile device.
How fast are lookups?
Lookups are extremely fast, with results typically returned in just milliseconds. This makes it safe and practical to run checks in real time, even within live message flows.
Can I combine validation and portability checks?
Yes, you can run both number validation and portability checks in a single workflow. They use the same API key, which simplifies integration and reduces overhead for your development team.
