Prefix-based lookup
Phone numbers are normalized before matching the most specific reference prefix.
HLR API
Phone-number insights.
A basis for your decisions.
Enrich your business workflows with number types, providers, and reference regions through prefix-based HLR lookup.
Solution scope
Understand phone-number data
with clear context.
The HLR API supports phone-number reference data integration. Results depend on the available dataset and mappings, rather than a live check on an operator's network.
Structured information
Number types, providers, and city or area-code references based on available mappings.
Integration requirements
Discuss response formats, API access, and usage policies for your application.
The scope above is a starting point for discussing your needs. Features, schedules, integrations, and implementation quotes are confirmed with the billio team.
Integration overview
Information that's
easy to process.
This example shows how lookup information can be structured. Production fields and API contracts follow the agreed integration documentation.
- Prefixes are preserved as strings.
- Matches use the longest applicable prefix.
- Reference regions are not a subscriber's current location.
Sample payloadILLUSTRATION
{
"success": true,
"data": {
"prefix": "08xx",
"number_type": "MOBILE",
"provider": "Illustrative provider",
"region": "Reference region"
},
"meta": {
"dataset": "illustration"
},
"error": null
}{
"number": "08xxxxxxxxxx"
}Illustrative data. No phone number is submitted or looked up.

Workflow overview
Steps that are
easy to understand.
01
Prepare the input
The system accepts and normalizes the number format according to the agreed rules.
02
Match the prefix
The canonical resolver uses longest-prefix matching against the applicable reference data.
03
Read the result
Mapping information is returned in a structured API response.
