Porting guide · Reviewed 2026-08-30

Prepare the records before moving a business phone number.

Portability and timing vary by number, country, losing carrier, records and eligibility. A submitted request is not a guaranteed completion date.

Three porting phases

01 · Prepare

Match account records

Collect the current carrier name, account and number details, service address and authorized account holder exactly as recorded.

02 · Authorize

Submit current documents

Complete the required authorization and provide a recent account record or invoice when requested.

03 · Validate

Test after confirmation

Verify inbound, outbound, caller identity, routing, voicemail, messaging and emergency records where applicable.

Prerequisite checklist

  • The number remains active with the current provider.
  • The person signing is authorized on the account.
  • Name, address, account identifier and numbers match current records.
  • No conflicting order, freeze or pending change blocks the request.
  • The target service has passed a portability and capability review.

Common rejection causes

Record mismatch

Business name, service address, account number or authorized person differs from the losing carrier record.

Number or order conflict

An incorrect number list, pending order, freeze or inactive service prevents validation.

Eligibility or document issue

The number is not portable in the requested context, or authorization/supporting records are incomplete or stale.

About timelines

Simple and complex ports can follow different review paths. Rejections, resubmissions, multi-number accounts, special services and carrier coordination can extend the process. Treat any estimate as conditional, not a guarantee, and preserve operational fallback plans.
