The Scenario
You supervise collections at a financial services company. A new batch of 5,000 debtor phone numbers just arrived from the data team, ready for the auto-dialer. Compliance requires carrier type, line type, and risk flags before the session starts. Dialing a number flagged as high-risk carries regulatory exposure.
The data team gave you raw phone numbers. No enrichment.
The bad version:
- Look up numbers one by one on a carrier lookup website — manageable for 10, impossible for 5,000.
- Export to a bulk lookup service, wait for the file, import it back, spend an hour reconciling column order.
- Skip enrichment, document that you requested it, and hope compliance doesn't audit this batch.
The auto-dialer session starts in four hours.
The Easy Way: One Prompt in SheetXAI
SheetXAI reads your Excel workbook and calls Interzoid's phone validation API for every row.
For each phone number in column A, call Interzoid to retrieve carrier name, line type (mobile/landline/VoIP), and risk score, then write those to columns B, C, and D.
What You Get
- Column B: carrier name per number.
- Column C: line type — mobile, landline, VoIP, or unknown.
- Column D: risk score from Interzoid.
- High-risk rows flagged automatically for exclusion before the dialer session.
What If the Data Is Not Quite Ready
Phone numbers are formatted inconsistently
Normalize all phone numbers in column A to 10-digit format without dashes or parentheses, write to column B, then call Interzoid for carrier, line type, and risk score, writing to columns C, D, and E.
You need E.164 format for the dialer system
Enrich the phone numbers in column C using Interzoid's phone profile API — write the normalized E.164 format, carrier, and geographic region to columns D, E, and F.
Some rows have blank phone numbers
Skip rows where column A is blank. For all other rows, call Interzoid for carrier, line type, and risk score. Flag blank rows as 'MISSING' in column B.
Full compliance pass in one shot
For each phone number in column A: normalize to 10-digit format and write to column B, call Interzoid for E.164 format, carrier, line type, and risk score writing to columns C through F. Flag rows where risk score exceeds 70 as 'HIGH RISK' in column G. Create a filtered view showing only non-HIGH RISK rows for the dialer export.
The auto-dialer session starts on time with a compliant call list.
