  • No complex services attached to the line

CAT C — Complex Port

Required if any of these apply:

  • ISDN lines
  • Hunt groups
  • PBX services
  • Bundled service packages
  • Multiple numbers on a single service

CAT Special

Mobile Verification Process

Mobile ports include an additional ownership verification step:

  1. A unique verification code is sent to each phone number being ported (via SMS or call)
  2. You must provide each code to BlazeSMS to confirm ownership
  3. All numbers must be verified before the port can proceed

LOA Requirements

  • Save as a non-editable PDF
  • Fill in all required fields completely
  • Information must match your current carrier's records exactly
  • Address must be a local Australian address (required for emergency services)

Common Rejection Reasons

Reason How to Fix
Company information mismatch Verify exact company name and details with current carrier before submitting
Complex services not declared Check for hunt groups, ISDN, or bundled services — let BlazeSMS know so the port is classified as CAT C
Associated numbers Ask current carrier to disassociate linked numbers, or port all associated numbers together
Disconnected number Ensure all numbers are still in-service — do NOT cancel with current carrier before port completes

FOC Date Changes

Once your port date is confirmed:

  • Minimum 48 business hours' notice required before the scheduled FOC date
  • Contact [email protected] to request changes

Key Definitions

  • CAT A/C/Special: Australian port categories that determine the complexity and timeline of a port. Category is based on the services attached to the number, not the number itself.
  • ABN (Australian Business Number): A unique 11-digit identifier for businesses registered in Australia. Required for business account ports.
  • Hunt Group: A feature where incoming calls are distributed across multiple lines — triggers CAT C classification.
  • ISDN (Integrated Services Digital Network): A type of digital phone line — triggers CAT C classification.
  • PBX (Private Branch Exchange): A private telephone network within an organization — triggers CAT C classification.

Notes

  • Australia's category system means you MUST correctly identify your port type upfront — misclassification is a common rejection reason
  • Mobile porting has the most stringent identity requirements (2 forms of government ID)
  • The mobile verification step (SMS/call codes) is unique to Australia and must be completed before the port proceeds
  • Never cancel your service with the current carrier before the port completes — disconnected numbers cannot be ported
  • Invoice must be recent (within 30 days)
