How POTSAudit Works

Three steps from bill to report in under a minute.

1

Upload your phone bill or enter a number

Drag and drop your carrier bill — AT&T, Verizon, Lumen, and most carriers supported in PDF, CSV, or Excel format. We extract every phone number and line description automatically using AI. Prefer to check a single number? Enter it directly without uploading anything.

Your uploaded bill is stored securely and available to download from your report.

2

We look up every line by wire center and carrier

Using the NPA-NXX (first 6 digits of each number) we identify the specific telephone wire center serving that line and cross-reference it against copper retirement filings. We also enrich each number with real-time carrier data:

  • Carrier — the current serving carrier for that number
  • Line technology — landline, VoIP, non-fixed VoIP, or mobile
  • Registered name — caller ID name on file, if available

Retirement status is determined from AT&T's FCC filings:

  • Retired — service has already ended
  • Deadline approaching — retirement within 90 days
  • Scheduled — retirement date set, over 90 days out
  • Notice filed — retirement process started, no date yet
  • Not listed — no retirement filing found

Get your report with replacement options

Every line is classified by type — fire alarm, elevator, fax, security, voice — and paired with its retirement status, carrier details, and a direct link to the FCC notice if one has been filed.

At-risk lines are matched with compliant replacement options (Ooma AirDial, Alarm.com CopperLink, VoIP alternatives) with estimated costs and savings. Your report has a permanent link you can share with your facilities team, contractor, or carrier.
