Format-tolerant phone parsing
The Telephone Parser interprets phone numbers regardless of formatting — spaces, dashes, parentheses, leading zeros and country prefixes are all normalised before analysis.
The solution leverages open-source telephone number parsing and geocoding libraries with proprietary functionality built on top — including carrier identification, line-type detection and geographic resolution.
The parser integrates with Search Cluster for indexing, inexact search recall and detailed record matching, and feeds the Telephone Matcher.
What it produces
Format conversion
National to international (E.164) and back, in canonical form.
Number components
Country prefix, area code and base number returned as separate fields.
Geocoding
Geographic location based on country and area-code data — useful for risk and routing decisions.
Mobile vs. fixed
Identify the line type from the number range — mobile, fixed-line, premium or special service.
Carrier
Initial carrier assignment based on number ranges (note: portability is not reflected).
Validation
Detect numbers that don't conform to any known plan — a useful signal for fraud and data quality.
What the components unlock
Storage canonicalisation
Store one canonical form (E.164) instead of whatever the user typed.
Phone matching
Feed structured numbers into Telephone Matcher for high-quality reconciliation.
Geographic routing
Route inbound calls or messages based on derived country and region.
Risk signals
Premium-rate or unusual ranges raise flags during onboarding and account verification.
